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.

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.

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.

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.

Now for all you non believers... GFY

that is all...

As a Californian, I'm in disbelief that anybody can maintain 60mph on the highway. That would be extremely dangerous out west.

S.

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).

I've been getting between 17-18.5 mpg. I've only filled up twice so far but I still think it's pretty decent

I'm consistently getting 20+ MPG out of my H3... Best tank that I have checked was 21.6


WAIT, I gota pee in my diaper first

20+ on the average (city/hwy)

BLESS YOU MR MILLION DOLLAR MAN !!!

RYD

I just picked up my Black H3 early last week. I also was curious as to actual MPG (and I suck at math) so I picked up THIS at ThinkGeek for like $130. Just hooked it up. When I fillup this afternoon and drive that tank empty, I'll post some numbers.

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.

Let me know how you like the ScanGauge. I was looking at those. They provide a lot of useful information.

well.. here in northern VA the speed limit is 55 and at 60 I'm over the limit.. I did have a school bus driver flip me off the other day as she roared past me but I just thought she was a HUMMER hater

Here in California speed limits are mostly ignored, exceptions are school zones and construction zones. Law breaking became a habit for 99% of the drivers with the stupid 55 federal limit that was repealed.

S.

for the most part Va operates on the pack speed. Go with the flow and generally you are safe. Unless you are the weaving, braking, speeding, lane changing, hair doing, sandwhich eating coffee drinker all over the place.

Oh that multi-tasking at high speeds can be deadly.

Don't get pulled over in OR...very expensive...

I sped through Oregon last year in a rental car running a radar detector, no tickets. People do drive slower there compared to California.

I just got 15 MPG on a 215 mile run!

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.

Dan

PLEASE let us know if you get 20+ AVERAGE city/hwy on a tank full...

Like our one lone buddy
