So if you are using gas that's 87% unleaded, is the other 13% leaded? 
The correct unit is octane not %, i.e. 87 octane.

I use 87 myself. That is what the recommend so that is what I use. I have a friend that only puts in 90 because he gets better mileage. I calculated it one day and showed him how yes he might get slightly higher mileage but it is actually costing him more. He still puts in 90 though 
On a side note, I can't wait for mine to break in. I have filled up twice, first 13.somthing MPG and the second time was 12.8

Mine is broken-in at about 5000 miles and still getting 14-15, but a lot of that is also because of the area here.
We got the winter blend fuel, sub zero temps......that all puts a hell of a dent in your mileage as far as I have heard. (On any vehicle)

WEll I just don't think the MPG is going to get much better. It is well below the advertised rate. I use the cheapest gas available.

I get 13-15 city, and the way I drive, and the number of lights I stop at, I can't complain. I got 18.85 on a trip to TN, driving normally at 80 mph. I use only regular.

I've been running Chevron regular since July'05. Lowest mileage 14.2mpg, highest 18mpg.
Usually I get 15mpg. That's running around Silicon Valley, lots of stop and go combined with freeway driving at 75-85mph.

Use what's recommended. Anything more is a waste.
The enigine is designed to run best at a certain octane level... 87 for the H3. The H3 can run on a higher octane, it just won't get any additional bennifit from it.
The more important thing to consider is the quality of the gas. Some stations sell cheap gas which may have a high water content or other contamenants. See which station/gas company sells rhe best quality 87 octane gas. You may need to run a couple tanks of it to clean out what the others have left behind.
Has anyone looked into the optimum level of ethynol for the H3? Most stations out here put ethynol in the gas for certain seasons. I see that GM is putting out a new motor which can run on over 80% ethynol.

- I agree, but I'm getting free Monthly $300 gas card from work so I may as well use premium gas.

i live in mexico and the fuel quality isnt great. i only use the premium and average +/- 15 per gallon. it is my understanding that the premium fuel reduces pinging and engine wear. although it costs more, i fell better using it.

I use 87 octane and before oil change (3 weeks ago) I was getting about 15 mpg and after oil change I'm averaging over 17 mpg over my normal travel route. I changed to semi-synthetic Castrol oil. I was surprised by the difference in gas mileage because I had adjusted the torsion bars at the time I changed oil.

Anything over 87 octane is a waste of money. I know this from a fuels engineer. Save the money for accessories on your H3!
