Real world H3 gas mileage

[funpilot]

Those of you who own the H3, can you post your gas mileage here? Thanks!!

[H2forMe]

Yes, that would be very interesting. The only reason I did not get the H2 was because of the gas mileage...

Thanks

[H2forMe]

anyone? How about Killian? Really interested in finding out real gas mileage.

Thanks...

Near as I can figure I'm getting 14-16 city, without the A/C on. With the A/C I figure about 12.

On the freeway I was getting anywhere from 15 to as high as 21. Yes, I know that's high for the H3 but I figured it on three separate occasions. Maybe it was more downhill than it looked.

That should probably improve too as more miles are put on the engine.

Why??

Also.. how do you guys measure MPG? I mean... how do you get the most accurate number?

i have a brochure from the dealer that 20 mpg city...

not close in real life...

I am amazed at these figures. I get just as good and better with a V8. Guessing it must be a weight issue.

Usually up to 10,000 miles, a new engine is actually still not 100% broken in. During that 10,000 miles, as the engine is broken in more, there is less mechanical friction being created. Therefore, with less friction, the engine will work less and return better mileage.

Ohhh ok Thanks for the info!!

The H3 book in my hand says 16 city 20 highway.

My 2004 V8 Tahoe Z71 only got 10 in the city and 17 Hwy. Without the A/c.

I seem to recall that one of the H2's chips was programmed to run somewhat richer for the first 5000 miles and then to lean out the fuel mixture. Is that true and if so is there anything similar on the H3?

Divide miles driven by gallons of fuel to fillup. do this several times to get an average.
