Wow! I thought I might be the only one who still hasn’t forgiven them for that. I haven’t bought gas from Exxon/Mobil since I was a teenager, except for two occasions when I ran dry in remote areas with no other fueling options. I don’t miss 'em either; Mobil in particular is comically overpriced. (At the Mobil station nearest my house, the grade of gas I buy is, at last check, a full 37 cents per gallon more expensive than the same grade of gas at the Arco directly across the street!)
That said, I don’t buy Arco gas either, but not only because of the BP gulf spill. It’s just bad gasoline. A modern car in good tune won’t notice much of a difference except in long-term fuel economy and fuel injector maintenance. But I’ve driven cars on the bare edge of drivability that ran okay on Texaco, Unocal, or Shell gasoline, but wouldn’t even idle on Arco.
