Hey, I was just wondering what grade of gas does everybody use out there. I know the owners video says everyting works fine using an 87 octane fuel, but I'm wondering if it's better or worse to use premium? I haven't done my gas milage up yet for the last month, but I'm sure it will be interesting, all using 87 octane fuel. Considering I drove her down to New Orleans from Iowa and back and out to chicago and back this month. Plus, I had a question about ethanol... will that really eat up the fuel injectors?

I'm not sure what the recommendation is for the 3.2L and 3.5L engines, but if you have the 2.7L, don't waste your money putting in anything other than 87 octane fuel. You won't see any real benefit. I know this because I experimented with the different fuel grades shortly after I bought my car. I saw no difference... even using premium (93 octane).

Follow the owner's manual. IMHO, you are wasting money any other way.
For a regular vs. premium perspective, go to the "Car and Driver" web site...they just did a story on this subject. HTH.

I used 92 octane for almost a year, and recently switched to 87 octane. I havent noticed any degredation of performance what-so-ever. Seems to run maybe even a little better? Will be hitting the 1/4 mile again pretty soon, and I plan on using 87 octane to see if my track numbers are any different. I am guess they will be the same as they were with 92 octane, so I'll probably be saving my self the 2 bucks per tank extra that premium costs from now on.

I run 87 in my R/T. My mechanic has been a close personal friend for about 15 years. I asked him about this when I first got the car. He says anything above 87 would be a waste, especially in a new engine. I tend to trust his opinion, since he's the one that has got to fix anything that goes wrong, and his time is free to me. :)
