Chevron = Texaco these days. Same stuff, since they're the same company.
BP has, well, almost forever, had one of the better additive packages.
In most recent times, Shell seems to have the better additives. Exxon, surprisingly, seems to do well, especially on the 10% Ethanol Blends. I was seeing the least Knock Retard on Exxon Gas, until I got some 100% BP or Shell....
