Although you might occasionally find some bad gas I think it's pretty much all the same. One thing I do is never fill up at a station where they are getting a gasoline delivery. I figure that any contaminates and water are settled to the bottom of the tank and when they are dumping in new gas it all gets stirred up and sent to the dispensing pump and on into your tank. Don't know for a fact this is true, but makes sense and it works for me!
