I'll be changing gas stations since I noticed that the Marathon station I frequent charges me an extra dollar to use a debit card. Not a lot of money, but its the principle. Anyway, there is a new Thornton's station that is even more convenient, but I've never had any experience with their fuel. Does anyone know anything about the quality/cleanliness of the fuel, or it's additive package?

 

It is Sunoco fuel here in Louisville. I've never had any problems with it.
