As a prior poster had said, all gas is the same, it all comes from the same tanks at the distribution center. It is the blending with the additives which differentiates one brand from another. The blending occurs when the delivery trucks are being filled.

All gasolines have a minimal amount of detergents and some additives but some brands have proprietary formulae that may make them "better" than others, but gasoline is gasoline and the differences are minimal.

The distribution centers are regional, and around here with the exception of Irving oil which apparently has its own center every other branded and non branded station gets their gas from the exact same tanks at the distribution center and the gas is therefore 99%+ identical.
