I was told recently by my girlfriend's mechanic that BP is the best gas available and that Shell is "not bad."
Prior to that I was told by a friend of mine who is an attorney for Exxon that Exxon gas is (you guessed it) the best gas available.
And long before that I was told by my ex-wife who works for a consumer advocacy group that as long as the gas company isn't "cheating," .... i.e. not selling one type of gas and claiming it to be higher, then they are all the same ... and that there are groups that go around and test gas to weed out bad gas stations.
OK ... so who the hell is right? I'm getting stressed out driving around on E looking for that elusive, green BP station :-)
