GAS MPG

[NJHummerGuy]

Just got my tank filled up for 1st time since getting the new wheels.....got 18mpg!
What are others getting?

[The Green Lantern]

http://www.elcova.com/infopop/emoticons/icon_mad.gif - city 12-14 mpg(supreme), highway 16-17 mpg

[DarthKarl]

I get about 14.5 mpg city and 17.5 on the highway.

[wannabeH3]

seems i get 14.5 everywhere...

[NoMoGMPG]

You all must wear steel shoes! I get 14mpg in my H1!

How come the H1 highway in hawaii is considered a interstate http://www.elcova.com/infopop/emoticons/icon_confused.gif.
Also How much would it cost me for a small house in hawaii. i just might retire early and Hawaii could be the place http://www.elcova.com/infopop/emoticons/icon_cool.gif (As long as i can get my H3 and 442 and bikes over there

[HumbleAg]

I'm up to 4500 miles now, and I've checked mileage on every tank. Best has been 18, worst 16. Almost all were right at 17. Mixture of highway/city driving, but not a whole lot of stop and go traffic.

There are three interstate highways on Oahu. They will connect to the US when Hawaii becomes a state (jk). Avg prices are in the $500k range.

BTW I am getting 14 mpg.

[black20]

14.5 miles city with 20 inc wheels

[PCBeach]

Automatic..Was doing 19.5 Hwy and 15.5 city..changed to Mobile 1 at 3000 miles.. Now with 5000m getting 20Hwy and 16 city.. Oh yes its flat here in the Florida panhandle and I am old and slow!!!Have checked every fillup.

[psywzrd]

I've yet to break 13mpg. I know I have a heavy foot but that seems a bit low to me.

[HummerJim]

Yep, 28,450 miles here and a consistent 18 mpg on the highway - mostly all highway lately.

[firm]

There's a difference in MPG with the base and with the adventure package. I was getting around 18-19 with the base, 16 with the adventure. Must be the tires. The base also accelerates better.

[fourfourto]

Its funny how they dont rate them differently. I wonder if they ever tested adventure mpg or
0-60 , 1/4 mile times ,braking ect.They probobly based all info on lux or base http://www.elcova.com/infopop/emoticons/icon_confused.gif

[Steve - SanJose]

All - I'm getting a consistent 15 mpg in mixed suburban driving around Silicon Valley. I've only done one coastal highway trip (not all freeway) and got 18 mpg.

Hummer Jim - what speed did you generally cruise at when you got 18mpg. I plan to take some road trips later which means cruising at 80 mph in central California. What type of mileage should I expect?

firm - I'm not surprised that the base accelerates better on the street (in high range) because of the significant difference in tire diameter. Of course in low range the adventure package will accelerate and climb better because of the shorter gearing.

[km406]

Is it better for gas mileage to use the cruise control or not? Also, how are you guys getting different numbers for your highway and city driving. I do a mix of both, so it's hard to estimate when I check my mileage at fill-up time.

[DarthKarl]

Originally posted by km406:

It all depends on your driving habits. The cruise control will generally want to down shift a lot in order to maintain the speed that you have set (that’s of course its job in life). This is especially true if you're driving on a hilly road. If you're looking for MPG over constant speed, then you're better off by controlling the accelerator yourself and letting your speed drop down on inclines (and therefore not down shifting as much as the cruise control would otherwise do). If you have a heavy foot on the highway (never letting your speed drop below the speed limit and downshifting a lot), then your MPG could actually be better with the cruise on.

[HummerJim]

Steve San Jose - I can tell you from my experiences in the Yukon where the roads are long and straight and the traffic is sparse that cruising 65 mph you will get in the 18s on flat pavement and crusing 80 mph you will get in the 16s - wind resistance is a big factor and the frontal area creates a lot of drag- induced and parasitic. My best ever was north of Whitehorse on the long (95 miles?) gradual downhill straighaway with a brisk tailwind running 66 mph with the cruise- an honest 20.2 mpg. I have the base, and I have heard mileage is not quite as good with the Adventure. I had so much fun up there I'm planning another trip only earlier in the summer for 2006 - late July probably.

[f5fstop]

I can say that my average of 18+ for highway driving from MI to TN in Sept, consisted of highway speeds around 75 from MI to TN, and in TN at 80 mph.
Almost the entire trip was set with the cruise on. From MI to KY is primarily flat, from Louisville KY, to Elizabeth Town KY, is hilly, from Elizabeth KY to TN border is primarily flat with a few rolling hills.
From the TN border Northern Nashville is flat with a long decline at Ridge Top. From Northern Nashville to Centerville, is hilly.
Trip home produced almost the same identical mileages.
This was on a new engine, not even broke in, temps were anywhere from the 60s to the 80s.

[NEOCON1]

with 4k on my automatic I get 16 around town my commute is 25 miles and about half freeway and half city I average 18 and thats going 70 on the freeway. On a run back from a trip to pismo truck loaded and 40 psi in tires got 21.5 mpg cruise was set about 63 and openroad for 200 miles was very pleased . So if your not in a hurry and run your tires a little high on pressure you can get over 20 mpg with an automatic .

[WikidPete]

Wow my first tank of gas got about 12 - 13 mpg http://www.elcova.com/infopop/emoticons/icon_eek.gif mixture of City / Highway driving. This time I filled up with 89 and well see how that does on the second tank. Hopefully gets better when the engine gets broken in.

[TNTH3]

First two tanks got 16.5 on 87.

[xburbman]

I was tracking it for about 8 tanks.....12-15mpg city/14-16 highway...but I have a very heavy foot...mostly 75-85mph on the highway. I was a little dissapointed, but in the end I just said "scr** it!"...it's Got2B cause of my heavy foot! I've very much enjoyed the way it drives.

thanks for clarifying... was expecting to hear that you needed to run like 89-91 octane for optimal performance....

[bigdog100]

Most accurate way to check mileage? Fill up, set 0 on trip, then drive, wait till empty and divide mileage by 23?

Is there a more accurate way?

[PARAGON]

Originally posted by bigdog100:

Is there a more accurate way? not even close.

fill up, keep up with mileage, fill up again, divide the amount of fuel it took to fill back up into the total mileage on the previous tank and voila.

Do that on a couple of fill ups and you know what your average is.

[RubHer Yellow Ducky]

BigDog

what do u do when u run out of gas?

RYD

[startin\' young]

filled up for the first time the other day got 16.8 city/highway. if you have the adv pak the highway miles is poted at 19 instead of 20 for base pkg

[HummerNewbie]

It you calculated your mileage correctly, I think you got the highest mileage anyone has gotten out of their first tank.

[yat74]

15 mpg Highway/city combined with the stock 265's, I'm looking to go to 285's let's see what happens.

[The Green Lantern]

1. first tank before all my mods = 16.8 mpg/city

2. after marker lights, sidesteps and splash guards = 14.7 mpg/city

3. SMA brushguard and fog lights = 14.2 mpg/city

4. 35's = 12.8 mpg/city after my first tank.

5. Gobi rack and offroad lights (next) = ?????? http://www.elcova.com/infopop/emoticons/icon_mad.gif

[Steve - SanJose]

My mileage has crept down lately to about 14.7 mpg (from 15) running around Silicon Valley (city combined with fast freeway driving). I consider the mileage to be acceptable for this type of truck running on Chevron regular.

My H3 was purchased in July and now has 15K miles. Tires are stock 32".

S.

[Kid Shyleen]

About 6.5K, and 15-16 MPG. Nothing to write home about. But then again, I do run it agressively around town...and why not...it's YELLOW!

You would have thought that the 5cyl engine would have provided more results. Especially given the available power. Dissapointed. I guess I'll have to upgrade to the Alpha, or the TD when it arrives...that'll show 'em! http://www.elcova.com/infopop/emoticons/icon_cool.gif

[tonio]

15 all around, and I'm not easy on it.

[Disnydad]

Okay, I've got just over 800 miles on the H3 and just finished my first mileage check. Right now with mostly local and a few 10 mile jaunts on the interstate I'm showing 15.778 mpg.

My F-150 5.4 V8 that I traded was getting 13.8 mpg local.

[Dave LV]

6600 miles.
As low as 11 mpg around town for a daily 6 mile commute.
15 mpg doing 80 mph.
21 mpg doing around 55 mph.

Cruise control supposedly gets better gas mileage because a human foot keeps moving just a little and thus pumps unnecessary gas in.

[RubHer Yellow Ducky]

Last Nite I happeded to calu my total average since mid -Jan when I got her...

Got around 3500 miles now so after 3 months getting overall around 15 mpg. That includes 1 trip to Orlando.

My right foot does weight a lot more then my left but i use cruise contro; as much as possible. Hate 2 think what it would be like if it wasn't level ground. Being able to use regular for the first time since 1998 is a plux...

RYD

[HummerJim]

37,270 miles on the H3 as of this morning. Still a tight machine with no rattles or annoying noises! My rear wheel flares are getting a little rock chipped (my only complaint), but I'm not a mud flaps kind of guy for the front wheels. Gas mileage for the last 7 fill ups has averaged 16.87, but this has been 75% highway travel with a heavy foot.

[Disnydad]

Just did another mileage check at about 1200 miles of mostly local driving. 16.3 this time.

[HummerNewbie]

Damn I must have a heavy foot. Just filled up this morning and with 3,238 miles I got 12.98 on the last tank. I drive pretty much all city except 3 miles each way to work on the highway. Of course it doesn't help that I do between 70 and 80 for those 3 miles.

[Steve - SanJose]

At 15,500 miles +, my last 5 tanks have averaged 14.7 - 15.9 mpg. City traffic combined with high speed freeway (70-85mph).

S.

[Huck BB62]

I was getting a consistant 16mpg commuting. My commute is 45 miles twisty mountain road down and up 4200' elevation change. I grannied it (easy gas pedal, keeping speed through the corners, losing speed up hills instead of keeping it constant, no passing etc.) last tank and got 18mpg. This is a great increase as it allows me one more day without filling up and saves $6 a tank. I've been calculating every tank. I'm sure that our H3 would get 20 on the freeway.

[H3HUMVEE]

I'm consistently getting 20+ MPG out of my H3... Best tank that I have checked was 21.6 and the worst was around 17 during "break in". this is with mixed driving and speeds under 65 MPH.

[Av1ator]

Years ago when the VW bug was getting big in America people used to brag about the great gas milage they were getting. WELL..this one gentlemen I know of was getting AMAZING gas milage..60-70 even a 100 miles to the gallon...it seems his neighbor was slipping a gallon or two in his tank to see how tall the tales would get!

20mpg is impressive, driving under 65mph in California is impossible on the freeway.

[Agriv8r]

have had 41 owners reporting 14.3 to 19.7, but no one getting over 20 yet.

[f5fstop]

Latest city driving, all stop and go to work and back, is 15.4 so it is going up to what it was last summer.
Can't complain, it is reated 16/20 or 16/19 and that is under ideal conditions.

Just remember all you in the west and other areas that use Ethanol fuel, your mileage will suffer a small amount.

the last tank I got 12.4 mpg http://www.elcova.com/infopop/emoticons/icon_mad.gif

[Beastmaster]

For those of you who are running the Adventure package or are running 33's, please adjust by increasing your total mileage by 3.7%.

So, if you're ran 100 miles on the odometer, you've actually run 103.7 miles.

The 3.7 percent can make a difference in regards to your overall MPG. For example (in a perfect mathematical world using 11 gallons of fuel exactly):

Running 32's (base/lux)
200 Miles run
11 Gallons used
200/11 = 18.18 MPG

Running 33's (Adventure)
200 Miles run (on odometer)
207.4 miles actual (3.7% difference)
11 Gallons used
207.4/11 = 18.854 MPG

For high mpg you could fill up on top of a hill that is 10 miles long coast down it at 65mph at the bottom refuel you mpg will be sky high
I did it with a murano and the gas computer said 99.9 mpg by the bottom of the hill http://www.elcova.com/infopop/emoticons/icon_biggrin.gif

In that situation the H3 should get at least 75mpg http://www.elcova.com/infopop/emoticons/icon_eek.gif

[Steve - SanJose]

Only once in over 15K miles have I hit 18mpg. But I haven't tried any long downhill runs with a fillup and I haven't fixed my lead foot.

Why? There are different calibrations for the off-road and the regular package. I have to assume GM has a different odo calibration in each one. So, if the vehicle came from the factory with the larger tires, the odo SHOULD be correct, those who installed larger tires will have an innacurate speedo. Even with that, your calculations will not be accurate for all H3s.
My speedometer is off by under two miles at 70 mph, calculated on two separate GPS units, on two different trips, and I even did the mile marker versus the stop watch a few times on flat ground in IN.
I'm probably getting a little less in mileage than I stated earlier, but it would be about .4 per mile.
Since those trips, I have uploaded two different calibrations but have not rechecked the miles on the speedo versus the GPS units. Hopefully, one of those calibrations corrected this error.

(NOTE: Federal Law allows a 5$ plus or minus on speedos.

So far I am so impressed with this vehicle that I almost forgot about mileage. I bought the base model with not one single option. (Don't need anything else) Slate blue. 5 speed. I decided when I bought it to either take the trrain to work, or keep it under 65 (barely).
Anyone driving nice and keeping track of mileage with a standard?

Welcome to the forum ... keep it under 65 and shift when the indicator flashes on the dash and you should get 20+ MPG .. of course no one on here will believe you http://www.elcova.com/infopop/emoticons/icon_wink.gif

[Scouts Out]

i have been doing allot of high way driving (Pittsburgh to Harrisburg) and Pittsburgh to Ft Knox and pittsburgh to Ft Dix. I consistantly averge over 18 and closer to 20 when I set the cruise at 75mgp and relax. Around town ( lots of hills) just sucks at around 12 mpg.

[Av1ator]

Let me throw one more log on this fire.

Maybe the ones that are getting really poor gas milage are ones that have low compression problems and don't know it yet.

My milage certainly got better after they put the new top end on it. Last tank I got 17.8 mostly interstate at 70 MPH..I do have the automatic transmision with adventure package. I have really tried to get better milage by watching the speed and the best I have seen is 18.2. Maybe with careful driving the smaller tires and the 5 speed you can break 20 MPG but I wouldn't have the patience to do it everday.

[RubHer Yellow Ducky]

LOOK

Cut all the name calling and BS.

All i'm saying is that only ONE person that we know of is getting 20+ MPG on the AVERAGE. I don't know how many are registered on the H-3 Forum, lets say 500 (i know i'm way off to high AND to low) but thats 1 in 500. The odds can't be correct, OR theres a lot of people who have compression problems and if thats it then GM has a really BIG PROBLEM.

SO

without name calling and BULL CHIT has anyone got a GOOD LEGIT ANSWER???

I would have to say that my average of 13 MPG is a matter of 90% city driving, almost always running 75-80 when on the highway and a not so light foot. I wish I was getting 17 or better but I love driving the H3 so much that I am still extremely happy driving it at 13 MPG.

Well, before all my mods I was getting 17.8 mpg average mostly city driving. But now I'm getting 12.4 mpg...but it's all good, gas mileage is never an issue for me, even I get 5 mpg I'll still be driving my H3 and go off roading. http://www.elcova.com/infopop/emoticons/icon_wink.gif

Yeah, I think that has something to do with it. I know I've put on a lot of weight (to my rig, not myself http://www.elcova.com/infopop/emoticons/icon_wink.gif ). With the weight of my UCP, roof rack, hi-lift, air compressor, toolbox, etc...its all got to have an effect on the mpg

My milage certainly got better after they put the new top end on it. Last tank I got 17.8 mostly interstate at 70 MPH..I do have the automatic transmision with adventure package. I have really tried to get better milage by watching the speed and the best I have seen is 18.2. Maybe with careful driving the smaller tires and the 5 speed you can break 20 MPG but I wouldn't have the patience to do it everday.

Interesting thought, but the PCM will start registering misfires, and turn on the MIL light, as soon as there is any notable wear in the intake valve guides of cylinder one. In addition, a rough idle should start quit soon after the MIL light comes on.
If you drive with the misfires, it might affect mileage enough to be noticeable; not sure.

I still only see one (1) person averaging 20+ MPG (city/hwy). Maybe he has an experimental engine in his that we or he doesn't know about

OR

As was stated the entire fleet of H-3's has compression problems (EXCEPT HIS)

I agree, 20+ is high. Only way I could see me getting that type of mileage on the highway is at around 55 going east bound through Nebraska or Kansas, with the cruise locked.
Last year on the highways, I did get 18+ running from Detroit to Nashville, no cruise, averaging about 80+, including the rolling hills of KY and TN. That was totally highway, except for stops for more fuel and pit stops for the doggie.

[Goosey]

First tank about 5/8 gone at 225 miles. Does anyone have reason to believe that mileage goes up significantly after breakin?
Also does the gas gage grop like a rock after 1/2 way?
Still lovin this vehicle, looking like 15.6 avg without lead foot.

[HummerNewbie]

I have not seen any increase in MPG after 3K miles and yes, the gauge drops much faster after 1/2 tank and even faster below 1/4 IMO.

[H3HUMVEE]

OK , RYD ... let me see if I can break this down for you, I'm sure you still wont believe me but I really don't care and I have no reason what so ever to make up my mileage to impress you or anyone else on this forum. OK here we go ... first off I'm driving a base model with the 5 speed manual transmission and the 32 inch tires, To get optimal gas mileage with the manual transmission the computer monitors the engines rpm's and torque and tells you when to shift via a little flashing icon on the dash. How many people in your survey are driving that combo??? I can also tell you with the 4:56 rear, speed is the big MPG killer in the H3 and that's why I keep my highway speeds at around 60 MPH when you get up to 70+ MPH your mileage will go right down the toilet.. also to get the best mileage I try to accelerate as slowly and smoothly as posable and use the shift indicator .. I will admit this is "slug" driving but I drive 90 miles a day to work and need to conserve my gas and with that kind of driving I'll get over 20 MPG every tank... If I drive my H3 hard, shifting between 2500 and 3000 RPM's and running 70+ MPH on the highway my mileage drops to around 18.. also I didn't start getting my best mileage until after 6,000 miles. As far as my math skill I have managed a multi million dollar company for the last 20 years and was probably able to calculate gas mileage before most of you stopped wetting yourselves. http://www.elcova.com/infopop/emoticons/icon_wink.gif

I'll go with that. I can see it is possible; although, I have to say it is definitely not a standard, but with that driving habit. Hell, I drive like a maniac, at 80 and I got 18.91 (figuring in the speedo versus GPS difference, 18.51).

Just a question, but if you manage a multi-million dollar company, why do you need to be so concerned about how much you spend on gas??? Seems to me that you would have enough money that it really wouldn't matter.

Around here if you drive 60 on the highway, you will get run over by school busses (and everyone else). I'm sure I don't make as much money as you, but I bought the H3 NOT as an economy vehicle and I knew what I was getting into. I don't see taking the chance of causing an accident worth saving a couple bucks a month (which is about all we're talking about here). But it may be different where you live, so to each his own.

Not bad at all since we went from Mojave CA and on thru Last Chance Canyon and Golar Gulch (again). We spent 6 hrs on the dirt roads much in low range and with lots of stops,rocks etc. I gassed up at home and still had 8 gallons in the tank!

I can dig it!

I am sure I can get 20 mpg with cruise control set at 70mph on a long hwy run.

[RubHer Yellow Ducky]

ZERO your trip meter when you FILL up with GAS.
The next time you Fill up divide the number of gallons & 10th of gallons you use into the total number of miles you have driven. Include the 10th of miles also. This will tell you your miles per gallon.

What we are looking for is if anyone else except MFW is AVERAGING (city/hwy) 20+ MPG.

If you are truly only getting 134 miles to every tank there is definitely something wrong or your statement isn't correct. I am leaning toward the latter.

[HUMRCHIC]

I should have clarified it is 67 miles each way...Oops..Sorry.

[HUMRCHIC]

OK, So I am I suppose to drive it until it is absolutely out of gas? Or close to it. I don't wanna get stuck atop the mountain I travel over everyday!!

[DarthKarl]

If you are filling up frequently and want to do a quick gas milage check, try going to a particular gas station and pump. Fill up until the pump clicks off. Then zero out the trip meter.

The next time you need to fill up, go back to the same station/pump (it also helps to fill up at about the same time of day - with approximately the same outside temperature) and fill it up again until it clicks off. Record the amount of gas it took and then check the trip meter...do the math and you should have a fairly accurate reading on what your mpg is. Of course doing a number of milage checks and averaging them all out over time will give you a better idea of what your overall mpg is.

[HummerNewbie]

Originally posted by HUMRCHIC:

I understood that, thus the 134 miles per tank.

Originally posted by HUMRCHIC:

Never said that. What I said is if you are only getting 134 miles per tank there is something wrong. Based on your statement that you fill up every day at $52 a pop, you would be at least fairly close to empty. My last fill up the low fuel light was on and it cost me $54, went 240 or so miles (don't recall exact mileage) and got right at 13 MPG. Based on roughly the same cost for the fill up and your stated miles for that tank you would be getting an estimated a 7.5 MPG. Now, these are estimates because I don't actually know what the cost of gas is where you are but our prices are generally on the high side of the national average. You have to take into consideration that you are driving over a mountain but the estimated 7.5 MPG is ugly. If you know how many gallons you put in after driving the 134 miles we can calculate what your MPG is.

[fourfourto]

Man some of you are making it so complicated.

Fill it up drive, divide miles driven by amount of gas used = MPG .Average a couple tanks if you want exact MPG for a time period.
Not rocket science http://www.elcova.com/infopop/emoticons/icon_biggrin.gif

Last tank I got 17 MPG mixed driving only 60-70 MPH on highway with running it 2 times for 5 minutes 4 times a week for dvd so not to stress battery(wife uses dvd during lunch time).No auto start used during last fill up.

[HUMRCHIC]

OK. Gas here is 2.99 per gallon. I filled up yesterday and it was 52.00. I went to work. 67 miles. I came home 67. miles. I now sit on a half of a tank. That is 134 miles per half tank plus roughly 2 is equally 268 per tank. That sounds sucky to me. Am I wrong?

[HUMRCHIC]

OH OH OH. I don't fill up EVERY DAY!!! It is every other day. I just noticed that in your post.

I calculate your mileage at 15.41 based on the info you provided. What I did was took the $52 you spent on gas and divide by $2.99 which gives you 17.39 gallons. I then took your two day 268 miles average and divided that by 17.39 gallon and got 15.41 MPG. Of course this is not by any means as accurate as basing it on your exact miles driven and gallons pumped but gets you close. Not bad considering that you are driving over a mountain two times a day. I live in extremely flat FL and I don't get that good.

I like it. Does provide a lot of info. Temps, pressures, fuel consumption, etc.
Little complicated to navigate though and the backlight could be brighter.
It tells me that on the last full tank I averaged 17.4 MPG. That was a long highway trip from NJ to PA and back. Terrain was mostly flat and I used cruise control a lot and was generally at 70mph.
The tank before that I averaged 14.3 MPG. That is my daily commute traffic. Real congested stop and go traffic from NJ to NY and back. Mostly flat, some hills, LOT of braking and accelerating, averaging between 15mph to 30mph.
Never found a good place to mount it permanently, so it just sits in top right corner on top of dash. Stays put, doesnt slide and wire to OBDII connector I leave coiled on side of dash. Never gets in way. Well I pretty much found out what I wanted to know. If anyone in NY/NJ area wants to borrow it and try it out, lemme know.

[nmikes]

on road trips I can get over 20 miles per tank... but that is with the tires at 40psi and cruise set at 65 cruising through Kansas. I don't know if it really makes a difference but I put the high octane in as well. Bombing around town I still get around 17mpg... but I never do any hard accelerating, braking, or powering through traffic. If you are getting single digit fuel economy something sounds wrong. I had a borla exhaust put on my F-150 and my fuel economy went to the ****ter... dealer said it was because the larger exhaust didn't provide enough back pressure for a clean burn. Don't know how true that is but I think hills and start and go traffic will put your fuel economy into the toilet with the gear ratios what they are. But there are people more informed on such things than I, I'm just hypostulating.

You'll never get that.

Unless you drive nothing but Highway at a continuous, 100 percent duty cycle of the truck (meaning, you fill the truck while you're driving down the road) AND at a constant speed that is never unwavering AND you are in an ideal road condition of perfectly flat with no additional wind drag, you will never achieve anywhere close to 20mpg.

Being realistic, if you achieve about 17-18mpg mixed mode (city/hwy), you're doing really, really great. The vehicle is only rated for 20MPG highway anyways, 16MPG city.

You will likely achieve the best gas mileage when you run it (probably) around 3500/4000 rpm. That's above the RPM for max torque, and it's approaching the highest point of the horsepower curve, which is at 5600 rpm. Somewhere in between 2800 rpm (max torque) and 5600 rpm (max horsepower) will be your magic number (in RPM) that will give you the most efficiency.

The results are in. On my FIRST tank and more city driving than usual with a base model and 5 spedd I'm getting 17.75 mpg avg. I am an engineer and my math is fine. I think 20+ on the highway is very obtainable. I'm hoping for 18+ average. That's pretty for for this class of vehicle. I'l switch to my usual synthetic oil and gain possibly as much as 1 mpg.

I'm sure your calculation of 17.75 is reasonably accurate. The hope of 20 mpg is not realistic if you drive normally. And the hope of synthetic oil adding 1 mpg is a dream. Enjoy your new H3.

We'll see. I am driving under 65. It seems like a lot of people are right now. In my last vehicle I got .9 mpg better using synthetic, but that was an equinox and more aerodynamic than the hummer, not shaped like a brick. I'll run a few tanks through this one, and post it here. I'm pretty sure I can squeeze 18+ average on my use.
PS: Being an engineer my math is ok, but spelling? Whew!

[Aubs]

We took a roadtrip to Colorado and back in the H3. At speeds of 70MPH, we got like 16-17MPG. When the speed limit went up to 75MPH, we got more like 13-14MPG. A lot of wind in some places didn't help, as we had to fight to keep it at 75.

My H2 at 70MPH gets 15 MPG.

It's that driving under 65 thing on the freeway that doesn't happen here in California, it's not safe to do so. http://www.elcova.com/infopop/emoticons/icon_smile.gif Maybe at $5.00 a gallon?...

[Agriv8r]

Have had a few more first tank replies at our dealership and over the last week or so, maybe 10 more replies, the best is 18.3 with the owner guessing about 80% highway.

[Steve - SanJose]

Last 4 tanks were 14.7, 15.4, 15.78, 15.76 running around Silicon Valley. Maybe I'm doing a little more freeway than usual, since I normally average just below 15mpg.

Ok, I have been putting premium (91) gas for the last 9 months and my last fill up I used the 87 octane and my mpg dropped to 10.2 http://www.elcova.com/infopop/emoticons/icon_mad.gif All city driving, same way to work, School and home. I was getting around 12.5 to 13.5 on the 91 octane. I'm using Chevron and I think the 87 burned faster than the 91....well that's my theory.

[Desert Dan]

I don't think Hummer/GM claimed more than 20 mpg on the hwy?

[Steve - SanJose]

H3 EPA ratings:

[MarK M]

after putting on my tires i'm about 15/16 now.

so i bought a civic!!! http://www.elcova.com/infopop/emoticons/icon_smile.gif

the H3 is now my official off road vehicle and for long family trips!

[Disnydad]

Just finished a 227 mile interstate run and recorded 18.01 mpg with the automatic trans running with the crusie on @ 70 mph.

[Aubs]

On our latest trip, we drove 60MPH all the way out to Colorado. The highest MPG was 23. The others I calculated were between 21-23 depending on the terrain and amount of stop/go off the interstate. So at 55-60MPH, I can now say that our H3 has beaten the EPA ratings.

However, raising the speed even 5MPH drops the mileage considerably.

By contrast, the H2 got about 11-12 MPG with a 12 foot box trailer. So you can see what driving slower really does. Moving up to 65MPH, the mileage drops to like 8-9.

[NEOCON1]

i have gotten 21.3 running 60 mph too :D

[f5fstop]

From the EPA Website:
Your vehicle's fuel economy will almost certainly vary from EPA's fuel economy rating.

Fuel economy is not a fixed number, it varies based on

Where you drive
How your drive
Many other factors
The EPA ratings estimate the MPG a "typical" driver should get under "typical" city and highway conditions. However, most drivers and driving environments aren't typical, and the factors that affect fuel economy can vary significantly:

Driver Behavior & Driving Conditions
Vehicle Condition & Maintenance
Variations in Fuels
Inherent Variations in Vehicles
Engine Break-In
So, the EPA rating is a useful tool for comparing vehicles when car buying, but it may not accurately predict the average MPG you will get.

I've been keeping a log over the past 3000 miles. Mostly country roads in rolling hills, with some city and some freeway driving. I don't race it, but I occasionally cruise at about 75 or so on the turnpike to avoid too many 18-wheel enemas. No long trips so far. I drive about 1500 miles a month. Use regular fuel.

New Federal Fuel Economy Ratings Set a Double Standard

By MATTHEW L. WALD
GOVERNMENT regulators, along with most American drivers, have long understood that the fuel economy estimates on the window stickers of new cars can be laughably optimistic. Even the federal fuel economy label serves notice that the actual mileage will depend on options, driving habits and other conditions.

So this month the Environmental Protection Agency revised its method for calculating mileage, an effort to provide more realistic numbers for shoppers considering a new vehicle. The change, which takes effect on 2008 model year vehicles, will be considerable; miles per gallon in city driving may drop by as much as 30 percent for gas-sippers like hybrids, the agency says. On average, city mileage for all vehicles is expected to be about 12 percent lower; highway estimates could be as much as 8 percent lower.

The new method of calculation recognizes that Americans drive faster, accelerate more quickly and use the air-conditioning more frequently than the federal mileage tests have been taking into account. It also takes into consideration changes in the ways Americans now buy and use vehicles, especially as large S.U.V.?s have evolved from work trucks to family haulers.

For the first time, trucks with a gross (fully loaded) weight rating of more than 8,500 pounds will have to carry fuel economy labels, beginning with the 2011 model year. Previously, large pickups and S.U.V.?s in this class (like the Hummer H2) were exempt; the new cutoff will be 10,000 pounds.

When the new stickers begin to appear, there is bound to be confusion. Labels carrying mileage figures based on the new calculations will be required on Sept. 1, 2007, making it plausible that the buyer of an ?08 Chevrolet Impala will see a lower m.p.g estimate on the window sticker than a neighbor who bought an ?07 model a week earlier ? even if the cars are mechanically identical.

Of course, the federal fuel economy ratings were not established for consumer education alone. The program began under the Energy Policy Conservation Act of 1975, after the Arab oil embargo, as part of an effort to improve fuel economy and reduce oil imports. The fuel economy data is compiled by the E.P.A.; in most cases, the tests are conducted by automakers and spot-checked by regulators.

To enforce a schedule of gradual improvements, the National Highway Traffic Safety Administration was given the authority to establish standards for corporate average fuel economy, or CAFE. Under the law, each automaker must maintain minimum fleet averages for its cars and trucks to avoid penalties. But here?s the rub: Even though regulators have now agreed that the method in use for estimating fuel economy is unrealistic and needs to be revised, it will continue to be used for calculating compliance with CAFE mandates.

The decision to approach the fuel economy problem through the label and not the vehicle came from Congress, which tried to address consumer dissatisfaction by ordering the change as part of the Energy Policy Act it passed in the summer of 2005.

Gas mileage is a touchy subject not only among consumers, but also in Congress, where it took an explicit political compromise to pass the ratings change. Part of the deal was that the older, less realistic formula would still be used for CAFE compliance, which is 27.5 miles a gallon for cars, and a figure for light trucks (pickups, vans and S.U.V.?s) of 22.2 m.p.g. for 2007.

Beyond knowing that the older mileage calculations are unrealistic, government regulators also know the fuel economy of the vehicle fleet now on American roads (which of course includes older vehicles). Each month the Energy Department publishes its own estimate after adding up the gallons of gasoline sold and dividing by the number of miles driven. It says cars get 22.4 miles a gallon, and vans, pickups and S.U.V.?s get 16.2.

While there is a general consensus that fuel economy is crucial to America and that the current rating system is out of kilter, the agreement ends there. For example, in the summer of 2005, during the debate over whether to change the sticker or the vehicle, Senator James M. Talent, Republican of Missouri, described the threat this way: ?Unreasonably higher CAFE standards would be a dagger at the heart of our auto manufacturing sector.?

Mr. Talent, discussing a proposal to raise the fuel economy requirement to 34 miles a gallon, said in floor debate that a Ford F-150 pickup built in Missouri would cost $3,000 more as a result. That would encourage people to buy import-brand trucks, he said, because those manufacturers could offset gas-guzzling trucks with a large number of smaller, more efficient vehicles. In fact, sales of the largest American-built trucks have slipped because of higher gas prices.

On the other side of the debate was Representative Sherwood Boehlert, Republican of New York and chairman of the House Science Committee. After the E.P.A. acted this month, he argued, ?The sticker itself isn?t worth much if there isn?t a follow-through on the Department of Transportation?s part,? to change car?s actual mileage.

?Shame on N.H.T.S.A.,? he said, summarizing the recent history of inaction on fuel economy standards by the department in charge of the issue, the National Highway Traffic Safety Administration. Mr. Boehlert predicted that the new Congress would toughen the standards.

The auto industry liked the change to the mileage calculation because it implies that drivers, not vehicles, are out of step with test procedures. A spokeswoman for the Alliance of Auto Manufacturers, Gloria Bergquist, said, ?How you drive really is the most important factor.?

Some incoming members of Congress plan to raise the issue of fuel economy in the next session, but it is not clear whether there is a consensus for tougher standards on cars. For light trucks, the Transportation Department has already ordered improvements in fuel economy, subject to economic feasibility and safety, but the change is modest, about 8 percent.

It did, however, change the system, setting a sliding scale based on each vehicle?s size. That had the effect of making fuel economy important to the manufacturers of each vehicle.

In contrast, the system in place for cars sets a corporate average, so that a company that specializes in small cars need not worry about improving its fuel economy, while a company that makes big cars may struggle to meet the standard. The Transportation Department has asked Congress to change the car rules to resemble the truck rules, so far without effect.

And while the new Congress will have a Democratic majority, the impact of that change on fuel economy rules is not clear; the issue has never broken down cleanly along party lines. Some Republicans have always looked with sympathy on the interests of the Detroit manufacturers and opposed fuel mandates; others have favored conservation.

Some Democrats were in the conservation category, too, but others took the position of the United Auto Workers, which has generally opposed stricter mandates.

The deeper problem, though, is that there is no free energy lunch, and cars with better fuel economy may seem less attractive in other ways. The mileage heroes may be smaller or slower; they may be priced higher because they are built with expensive, lightweight materials or use complex powertrains, as gas-electric hybrids do.

And the federal government?s recent track record on reducing oil dependence is dismal. In 1992, stung by the run-up in prices after Iraq invaded Kuwait, Congress passed an energy law that called for 10 percent of cars to run on something other than gasoline by the then far-off year of 2000. But the price of gasoline came back down, and the Energy Department found it could not swim against the economic tide. So transportation is still 97 percent dependent on oil.

There is another route, however. Many of the mandates on car emissions originated with California and spread to other states and the federal government. Now California and other states are seeking to regulate greenhouse gas emissions, which would have the result of requiring better mileage, since the amount of carbon dioxide emitted depends on the amount of hydrocarbons burned, either as gasoline or diesel fuel.

The case is now before the Supreme Court, and if it rules in the states? favor, states could effectively regulate fuel economy. Some would probably do so vigorously ? Gov. Arnold Schwarzenegger of California has often said he aspires for his state to be the center of the ?carbon-free world.?

Recent H3 mileage last 2 days was 16.4 mpg for me (1/3 suburban city and 2/3 fast freeway driving at 80-85 mph).

S.

[Interleukin]

Had my H3 since July, only have about 5,000 miles on it. I drive about 25+ miles interstate/city each day to and from work and surprisingly have seen my MPG drop from the first few fill-ups back in July/Aug.

Back then I was hitting 15.5 but now it is hanging between 12.8 and 13.2. This is hauling ass mpg though, I routinely drive it on the interstate at 75-80 mph. I expected an overall everyday mpg of 13-15 when I bought, so this is not surprising. However, I guess I have been a little surprised that it dropped upon "breaking in."

[f5fstop]

Colder weather will bring a drop in fuel mileage. So, hopefully, your mileage will go back up when the weather turns warmer. My city driving dropped from around 14.5 to around 13-13.5 last winter and this winter, but after last winter it went back up. Takes too long for the engine to warm up, thus the fuel stays a bit richer for a longer period of time.

I should also note that this summer when traveling to Utah, I noticed a one to two mile difference in fuel mileage from heading west to heading east. Heading west usually means heading into the wind, and that cut my mileage, while heading east increased my mileage.

[HumbleAg]

Recent trip back from TN, I averaged 18.29916931 on one leg of the journey....


I think in a calculation this precise, you would need to factor in the evaporation coefficients for both the initial and subsequent fill ups, normalized for standard pressure and temperature. In addition, the varying load capacity due to Big Mac consumption and subsequent unloading would also cause variances.

Or you coud just say "screw it", I'm driving the cool truck that I want to drive and I don't really care about mileage.

:D

I got 19.6 on a 200 mile or so trip a month ago, about 40 degree temps, not alot of hills, averaged around 70-75 with the cruise control

:D

Not to be mean, but there should be no evaporation coefficient since it is a closed fuel system, what evaporates is burned when the carbon canister is purged by the canister purge solenoid. That is, as long as the fuel cap is still on.:D
As for varying load capacity...I don't eat when driving except at the end of the night, so my fuel mileage should get better with each rest stop.:D

I CAN, I DO and I WILL use that phrase so long as they act in that manor. To belittle people who have a different view over an SUV, or a part, or a modification is not excusable.

I learned many years ago as a child after being beat up because I was Jewish, being called a JEW, a KIKE and many other things what "NEVER AGAIN" ment. There came a point where I learned to defend myself. A point of learning when to run and when to fight. Of learning to forgive but never forget.

[Dani]

the majority of my driving is highway with less than 5% being city. Before I had to have engine work done- I honestly used to get close to 380 miles before the light would come on. However, for some reason- ever since the dealership replaced the cylinders- the gas mileage isn't quite what it used to be but it's still pretty damn good.

[Steve - SanJose]

Wow 360 miles before the light comes on, probably about 18mpg, pretty good. I've only seen 18 mpg once in my H3. But my long freeway drives in California usually involve speeds in the 75-90mph range and the mileage never exceeds 17mpg.

From somewhere on the KS turnpike to Vandalia, IL is 365.90 miles, and that is when I filled up with 20.007 gallons this July. (18.288 mpg) Could have easily gone up to 400+ miles on the odo.

Some people have reported 19-22 on a nice long road trip, no mountains, no hills, cruise control, 65mph and lower, etc etc...

In real life even after your first 500 to 5000 miles you will see 12 to 18 mpg depending where you live, your top speed, use of cruise control, HOW HEAVY YOUR RIGHT FOOT IS, etc

I have around 12000 miles on my yellow one and 3000 on the gray, both are averaging around 15mpg.

Wow 18mpg, must be some slow highway speeds. Takes more self-restraint than I have to drive that slow. I've only seen 18 mpg once in 29000 miles of driving my H3. But freeway speeds in much of California are 75-90 mph.

Couple of secrets...

DON'T drive it like a tank
DON'T be the first off the line
Coast a little
Loose weight in your right foot
USE cruise control as much as possible
Carry as little extra weight as possible (leave your anvil at home)
Make your tire pressure close to high normal
Don't fart when passengers are in the vehicle

Some people have reported 19-22 on a nice long road trip, no mountains, no hills, cruise control, 65mph and lower, etc etc...

In real life even after your first 500 to 5000 miles you will see 12 to 18 mpg depending where you live, your top speed, use of cruise control, HOW HEAVY YOUR RIGHT FOOT IS, etc

I have around 12000 miles on my yellow one and 3000 on the gray, both are averaging around 15mpg.

Thank goodness we can burn regular gasoline.

You can burn it, but I hope you're not using that in your truck. Actually, I never even see it being sold.:shhh:

Ezra spots a VW Passat wagon with a bumper sticker reading "One less SUV":... You know, maybe you have the right to be this kind of sanctimonious **** if you put that sticker on your bike. But if you're driving a car? Any car? I think that qualifies as hypocrisy. Especially if your car gets between 18 and 23 mpg depending on the model; that's only 2 mpg better than a Hummer H3. ..

Snake, if you NEVER have seen regular gas being sold you have lived a sheltered life.

The H-3 calls for regular gas and runs excellent on it...
