is there any difference in the gasoline sold by big chain gas stations and little ones?

Question

I’m wondering about places like Chevron, ARCO, etc., as opposed to the little “Space Age” or “Comet” or other gas stations in my neighborhood. Lately the big chains are a solid fifty cents more per gallon.

The government requires certain base additives. All gasoline in your area comes from the same tank farm. After the tanker has filled up with the base gasoline, the additive package that makes it a specific brand is added.

You’ll typically be getting the same base gasoline without the proprietary additive packages.
