Regular unleaded

I believe regular is considered 87 octane in most states.

34,575

As for brands. Shell Exxon Sunoco. Those are my favorites. As for crappy name brands. Gulf. Hess. Citgo.

22,685

a car will run best with higher octane gas- and forget the ethanol- that stuff just gums up fuel systems, especially if it is sitting- so it depends on how much money you have, and if you can find gas without the bio- additive-
