Most of our shops are not tied to one brand of gas. This allows us to purchase quality gasoline from a number of different suppliers at the best price possible. No matter where the gasoline is purchased from, it comes from “big oil”. Much of the United State’s crude oil supply used for refining comes from foreign sources. Since refined gasoline products are openly traded on the world market, it is uncertain that anyone can be guaranteed where the oil to make it has come from.
