With my cruise set at 65, I just drove a 400 mile round trip and averaged 18.233 Other then a few brief moments at 80 going through Seattle to keep from getting run over by those crazy drivers, I let the cruise do all of the work. I get in town what you got on the freeway. I'd say your speed is what killed yours more then anything though.

 

Yeah it's definitely the speed that killed the mileage. 60-65 will get way better results. After all, it's only a 4-speed auto.

 

Hi,

I have a bit more than 10.000 miles on the clock of my H3 and the actual gas mileage is 15.2 mpg highway and 14 mpg city.
I´m from Germany and for European standards it´s still a lot.
Actually we have a gallon price of 5 Euros, which are approximately 6.5 US $
But I love my H3!

I filled up with my second tank full last night, on the first tank with mostly all city driving (with a lot of stop and go traffic) I got 15.1 miles to the gallon. I was hoping for a little better, but overall it's not bad for the weight and bulk of the H3. At least GM pays for 1 dollar of every gallon I buy for the next year.

I have 485 Miles on the Odometer..... 2nd fill up today gave me a 14.6 MPG. average. Not bad, about the same as the Honda Pilot we got rid of for the H3.

 

Think i got better mileage in the winter. Im also wondering if anyone is driving around at high alltitudes and what kinds of numbers they are bringing in? Do they tune them for the thinner air?

 

I useually get around 16 sometime more or less. Unless i do a long trip and eat a tank all at once.

 

Within reason the PCM will adjust for the less dense atmosphere in higher altitudes. This is what the Mass Air Flow sensor is for.

 

Just checked mine again last night..on a reprogrammed PCM (thanks to Jay) with 89 octane I got 17.8 in 100 heat and A/C blasting, all city.

 

Price in Big Sur CA, can you dig it?
