Here in MA, we have Pride gas which is the cheapest in the State, actually next to the cheapest as which is Cumberland farms and it's 93 octanes and I see numerous Mustangs, Vettes, etc high end vehicles gassing up there so I think the gas moves quite well.
Funny how we worry about what kind of gas we use but we have the worst "diets" for ourselves, all we have to look is around us and see it...
