I use chevron and shell for the most part because of location to places i go (they are everywhere) but i'll stop at a 76 now an then if the price is right.. for a long trip where i'm not going to be thrashing on the engine i'll use safeway gas, but thats just to save money an like i said i dont have any fun with that gas in the tank.
also i only use 92oct, its the highest we have at the pump locally.
