I have never had any one brand that gave me better performance/reliability than another. Some will say stick with the high-end brands like Texaco, Exxon, Chevron (your region may vary) because they have all the additives. I have found that using Bradley and any other "stop-and-shop" gas has always netted me the same results. I now usually buy gas from the same station that I have a relationship with because good service and friendly acquaintances are important to me. It has nothing to do with the brand.

And yes - run high-octane gas as much as possible.
