I used ARCO for 15 years in my old Chevy and then went over Von's (Saveway) because of the $0.10 a gallon discount just before I bought the TOH. In southern Calf. I understand the gas is either local or Alaska. I've never had a bad tank in the last 20 years. I usually fill up when the tank has less than 2 gallons left. I am one of those people that don't like to fill up. That's the reason I bought a TOH for 600 mile fill ups.
