I really have to laugh when people talk about "grades" of gasoline...the "dregs" of the refinery.
I dated a girl whose father was a foreman in an oil refinery in Tulsa, Oklahoma. Basically, the gas is all the same. The Conoco, Texaco, Exxon, etc trucks pull up to the same refinery and take on the same gas. Which ever refinery is closest, basically. As to gasoline's with detergents and additives...he said they're not worth it--same gas just a few chemicals added.
But, like PT Barnum said, there's a sucker born every minute. (Did he say that?) Oh well, someone did.
