gas mph 05 vs 08

[HummerJim]

It depends mainly on how heavy your foot is, but '03 to '08s are pretty similar when it comes to mpG. The big difference is having to run premium gas in the '08. I'm looking forward to a road test of the '09 with the E85 engine.

Your really gonna get a lot of, "If Gas mileage is a concern, The H2 is not for you." from this site. And that is a correct statement. 10 MPG - 12 MPG is not enough to cry over. I have an 01 Z71 that gets 12. So what is truly the diff? I would gestimate that with age the 03 will get a little less than a new one, but not enough to really be concerned. I may be wrong but you would figure tweaks here and there, along with aging on the air/fuel delivery/exhaust systems may restrict mileage a tad. I do not even look at gas prices any more. Too depressing. But Those middle easterners are not raining on my parade and keeping me from gettiing one. You HEAR THAT OSAMA? Screw you and your OIL PRICES. Oh, BTW, Go F yourself Hurricane IKE!

2008 H2's DO NOT require using 91 Octane in them. The recommended gasoline for 2008 is still 87 Octane (Regular Unleaded). Uping the octane is drivers preference.

Don't hold back. Tell us how you REALLY feel. LOL

With regards to increasing the octane level on the H2, I agree you will always get a better ride uping the octane. But that is with any vehicle, whether its a H2 or a Ford Escort. With respect to recommended octane, it is what the manufacturer specifies as an octane that will not damage the engine over the life of the vehicle.

I also will pull out the owners manual and double check my eyesight.

Interesting topic of discussion, maybe I will have to experiment with high octane as well.

I stand corrected. According the the owners manual, 91 is what is recommended, but it does say that you can use 87 octane. Which is different then what the Service manual says, which just specifies 87 octane.

Very interesting.

I pulled the owners manual out too, and 91 octane is "the recommended fuel" for the '08 H2. I've run regular twice and noted that it downshifts more on hills and doesn't idle as smoothly.

Now that you say that, mine doesnt have a rough idle anymore now that I use 91 fuel. It idled like a high lift cam was in it when I used regular fuel.
