Pardon my cynicism, but after you push the button on the gas pump suggesting you want premium gas, are we really getting it?

I believe my county checks occasionally that they price a gallon of gas for an honest gallon of fluid. But what about the gas itself?

Some times I actually notice a difference in the way the car drives.

Please suggest I should be more accepting of the American businessman.
