what's your favorite/best gas to use in your high mileade max?
 

since there are so many different brands of gas out there, ( i know, they all pretty much come from the same place ) what brand of gas do you use and hows your mileage. i filled 25.00 worth of shell 93 octane on friday and my needle has barely moved from under 3 quarters of a tank to a half with over 100 plus miles of city/local traffic. i'm really amazed as i usually get alot worse than that with 89 or "plus"gas. and i drive maxy relatively fast, but around town i keep it within the limit.

Mine has 152k and i put nothing but branded 93, i.e. BP, Exxon, Hess.
I do have an intermittent code for an O2, mileage could be better..

293,xxx here. I usually run safeway premium, but lately been filling up on chevron premium with the work gas card. No difference noticed.

I'm running 87 with TC-W3. I'm not looking for performance out of it now a days. Just looking for good range.
