Thats how it works, high volume stations are the best to purchase from, they have a high turn over. Which usualy means cheap gas.

I talked to an engineer a few years back that designed additive packages for gas, he pretty much said its all BS. He said that what you want to do is buy all different brands because they pretty much clean eachother out.

I have always bought the cheapist gas I can find and don't notice a difference.
