How low can you go.... [Archive] - Hummer Forums by Elcova

On a tank of fuel. Traveling through the hills of western NY (primarily I-86) from Watkins Glen to outside Erie PA, I was able to hit 365.40 miles before the LOW FUEL light came on. Speeds were between 70-75, but it was quite hilly.
Fuel mileage was 17.78 mpg (20.546 gallons to fill).

The next leg from Erie to Rochester Hills gave me 18.6 MPG, but I was traveling on flat land, through Ohio (and it seemed like there were Ohio state troopers every other mile) so speed were between 65 and 70, then back up to 80 in MI:D .

(I actually have a photo of the low fuel and mileage, but it appears for some reason, I cannot link to Comcast anymore.)

17.8 is great! In Denver with 35's, we get around 11 with ours. :crying:

My H2 gets better mpg! :giggling: I avg. 14 to 15mpg in that one.

That's great! I get 16 to 17 on long highway trips. Usually get around 15 around town. Lots of cops out this weekend around here.

City is around 14-15, but around here it is drive one mile, stop, drive another mile, stop. Whoever controls the lighting in MI is an imbecile.

OK, i'll preface this with a few details from my last vehicle: Infiniti QX4 (bascially a Pathfinder which I am sure you all knew). Bought it used with about 26.5K miles on it. At about 80K I put new tires on it because winter was coming and I thought 80K on a set of tires was a little unusual and better to be safe then sorry. I think the stock tires are rated for 50K.
At about 88K I had the front disc brakes done (new pads and rotors) for the first time! 88K on brakes? Even if they were done before I purchaes the truck, that it still about 60K on the brakes. I inquired about the back drums. Dealer said they were fine. They'd adjust them. Last oil change at 109K miles, I asked about rear brakes. "Nope. They're fine." So with that said, I am not too hard on my vehicles I guess.

H3 now is about 1 month old, did a few road trips into the Adirondacks. Have about 2100 miles on her now. My second tank got a reported 20 mph, pretty much straight highway miles. And the average of all the fills ups is 19MPG. So, that said, I have reached the 400mile odom mark on 1 tank, but usually try to fill up on a Sunday when the local gas station has 5 cent off a gallon sale. My driving usually stays under 75mph on the high way. So I am pretty happy with the truck! :jump:

Had my H3 for 14 months/23K miles. 14-15mpg city/suburban and 16-17mpg fast freeway (70-85mph). Highest mileage was 18mpg once.

I really have began to track my milage as city, highway and long trip. Around town I usually get around 13. Highway I average about 17. Long trips here I cruise for 4 hours at 70-80 MPH I can get almost 20.

I just got back from a 4300 miles road trip. MPG from east Texas through OK,KS and Nebraska ave 17.6. MPG through South Dakota, Wyoming and down through Colorado ave 15.4 ( this was mostly the rockies, pikes peak and the black hills). Speeds were 70 -75 on interstate.

By far the single most effective mod to improve mpg was to increase tire pressure. I now increase to 48psf on long highway trips (from regular 42 in city), and get maybe 1mpg better, without changing my driving style (pedal to the metal ;)).

So, on a hot day, running the x-ways, you are hitting approx. 52 psi in your tires? What is the max pressure labeled on the tire?:D

My tires are set to 50 psi and I'm getting like 12 mpg. about 230 miles when the low fuel light come on. :dancingbanana:

I just filled up the other day at 352 miles and it was just a bit over 20 gallons at 17.65 mpg. And yes the low fuel light was on.

PackerFever

09-07-2006, 07:30 PM

I hit 395 miles the other day and probably could have gone further....but I chickened out. Turns out I put in 21.6 gallons at that fill.

Does the H3 have a 22 or 23 gallon tank?

oh yea, I have 26K miles on it adn the mileage definetly got better after about 8000 miles and continues to improve.

23 gal I believe.

Last night: 399.5 miles when indicator came on. Went 5 miles to the gas station and filled up (21.1 gals). I know I can do better. :)

Check the old posts about MPG. There is a charactor there who claims over 20MPH Average.

I think its all downhill though...

I don't have a 3, but traveling to Moab in the black truck the fuel light came on somewhere in never-neverland Kansas (Damn KS). I couldn't find a gas station out there at all. Then the "Mileage To Go" meter stopped giving me a range to empty and just said "Low".

Holy crap!!! In the middle of freaking nowhere without a jerrycan!

I was on the phone with Adam and sweating bullets!

FINALLY, a station! I filled up 29.5 gallons in a 32 gallon tank getting under 12mpg! Figuring the last 1.5-2 gallons are unusable, well, I was pretty close to a problem.

BTW, that truck used premium fuel at over $3 a gallon at the time! 4,200 miles Buddy... 4,200 miles...

I think we are seeing the folks with the 5-speed tranny getting the good mileage here.
I get very close to 18 mpg pulling a flatbed trailer with two ATV's. I also have a rooftop hardshell cargo box for added resistance. I keep it at 70 mph or less. I run premium gas and Mobil 1 oil.

Come on 5-speeds lets toot our own horns! (not to mention the crawl ratio) oops did I say that out loud?

Yup. 5-speed manual. I am fairly casual driver. No strong starts. I run 87-octane gas. Under 75 on the highway. Commute to work (25 minutes) is mostly highway. Not very much stop and start. After about 8 fill ups (about 3600 miles on her), I average just above 19mpg. Can't complain.

Avg 17 to 18 MPG once 19 with Auto Trans and cold air mod...:beerchug:

From Florida to Arizona I got as much as 21 mpg using air occasionally doing 65 to 70 mph.

I have an automatic tranny.

Going to and from work and riding around in town I just calculated 19 mpg this morning. I guess they knew what they were doing putting the I-5 into a 4 ton vehicle; acceleration off the line is very strong IMHO, even though I don't do a lot of jackrabbit starts. I use Mobil synthetic also.

I have had absolutely no problems whatsoever at 14,000 miles. Only thing that bugs me is the rear seats don't lay down flat, no rear AC vents for passengers and I need a rear view cam. I backed into and ran over a mailbox yesterday; not a scratch though.

On a recent trip I got 17mpg w/o trying.

The A/C was one on, 70-75mph, no cruise control on. The truck was loaded not me.

After a long stretch (150 miles+) of dirt roads and a high pass we filled up and I still had 14 gallons in the tank!

I got real similar mileage to my friend's V6 Toyota 4-Runner and I kept telling him my truck weighs more, bigger tires and FT 4x4.

July 4th weekend holiday drive back from Blacksburg VA, to upstate NY. About 416 miles on the tank of gas when Low Fuel indicator came on. first pic - still has room to go (over 400 miles), second pic (hard to see) 418.8 miles when I pulled into the gas station after a mile of two with low fuel. Filled up the tank. I think it was just over 20 gal.

I have about 7500 miles on my 3 now and I average 19.5 mpg. I drive 105 miles per day round trip to/from work. Two lane higways mostly. Never have a chance to go over 60 mph.

I was getting around 19 mpg with stock tires. Now that I jumped to 35s I get 15/16 mpg, around 320 miles on a tank. Not a huge hit in mpg, but I really don't care because i love the look and the compliments I get on the 35s. Just curious, what size tires is everyone running when they post their mpg.

when u guys test your mileage, do you wait until the low fuel light comes on? or when it just hits "e"?

Ever since I went to the smooth 35" BFG A/T I am at the pump alot.Who cares they are great on and off road and it looks saaweet.....:beerchug:32''ers 19mpg/// 35''ers maybe 13mpg....Also running a K&N air filter.....

I agree...I have no idea how you guys all get such great gas mileage (relatively speaking) and I get such ****ty mileage.

The MOST I have ever gotten is maybe 16 and I average around 12 or 13. Could the reason be is that I live and drive in Southern California?????

In defense of Moyello, I think he was commenting on him NOT caring about the change in his gas milage after changing tires.
