What are you getting, I have 5 speed and after 1500 miles I am average 13 MPG with very conservative driving style.

 

I fixed your poll...I gave it an open ended deadline time.

 

I'm getting 12.4 mpg, mostly city driving on Chevron's 91 premium.

 

Try using 87 octane for a while..91 octane is not needed in the H3, and in fact you're wasting your money, because the engine is tuned for 87..So this may improve your mileage.

 

My average is 16.4 over 5700 miles. I don't track hwy vs city separately, just by tankful. My highest was 17.3 mpg, my lowest was 14.3 mpg.

I tried the 87 for two fill ups but it's worst - 10.8 mpg. I think 87 burned faster than the 91....well that's my theory. And I got 35's on, marker lights, SMA heavy duty brushguard with fog lights and rockers.

 

Dennis thx.

I have gotten

10.6
11.9
14.3
12.8
12.3

in order of use. Interestingly I drove aggressively during the 14.3. It is a mix of 70city/30hwy. I have the pizza cutter 265's and just bumped up to 39psi to see if that makes a diff from 32psi on the tires.

Dennis do you know of anyone that can fab a custom front bumper? I would like the wings cut of the plastic bumper and sides filled in and then cast in steel to get more of a H1 front look.

 

No, I sure don't..sorry..But give it time, maybe someone will chime in with an idea for you...good luck, that's sounds like it might look pretty snazzy


..Yeah you might have the extra load..But I'm inclined to think that maybe the Engine's fuel management is a little rich...Try calling the dealer and see if they'll reflash the computer...There is suppose to be an up-graded program available....Not sure if it applies to all VIN ranges, but it wouldn't hurt to get a reboot as it were...Because I think you are getting way to low of mileage..And yes, the 91+ octane does burn slower..But inturn, it will carbon up the engine too, as it's not tuned for that higher octane.

 

thanks, so, what should I tell them exactly? I just don't wanna hear them giving me some BS answers.

 

I understand that..you want to be armed..

Just tell them your mileage sux, and you have a feeling you are not tuned properly..My dealer said to bring it in and they'll throw it on their diagnostic machine and look over all the operating settings, to make sure nothing is out of bounds...If they give you any push back..Tell them the mileage you're getting is like that of an H2..it ain't normal!
