Gasoline brand question

[g222leav]

For all you Chicago-Land owners, do you have a preference of gas station? E.g. Shell vs. BP vs. Marathon vs. citgo...etc...

I had a buddy that swore Amoco Ultimate was the only thing he would ever use for his car and that all others were crap.

Is there any particular ones I should avoid?

as long as you're using one of the bigger names you are good. our cars (n54) has direct injection so the detergents actually don't do much for us anyways, we have to have valve cleanings regardless

[mdosu]

any top tier would work

I used to swear by Mobil.

Now I use BP ultimate.
