We stopped for gasoline yesterday at the ARCO station in Kingston, WA. Shortly after getting the gasoline, our engine started running rough. Used HEET, but still the engine sputtered and ran rough. Had to leave the car at a friend's house when the check engine light came on. Called ARCO today, but they refuse to accept responsibility, insisting that it couldn't possibly be their gasoline since they test it every week. We are boycotting the company after this and ensuring that everyone we know hears about their bad gasoline. read full review »
