What brand of gas do you use?

[gmboxster]

Don't know of the particular brand but it's always 93 octane. I was wondering if a lower octane rating would make a big difference, considering gas prices these days..

Cheveron 92 Octane in Washington State.

chevron, or 76, its a toss up.

NEVER shell. it made my jeep unhappy, hurt my old scirocco, and i think a buddy put it in my truck recently, when he borrowed it, and 1/2 way though the tank, I knew it wasn't chevron, cause the mileage sucked.

Amoco/BP or Sunoco, usually 93 (occasionally 94).

raceway...runs fine with it....

I use Shell V-Power 93 Octane here in New York. When I lived in CA it was Chevron or Shell in that preference order. But in California the max Octane was only 91 if my memory is right.
