I just rec'd. a "kit" in the mail that came from VW. A yellow sticker for the fueling openig warning of low sulfer fuel only. I use the Gulf since it has a good feel and 45 cetane where most offer 40.
Do any of you use a fuel additive? I know VW warns against using this highly BUT then they actually sell one called Stanodyne. It seems a bit contradictory.
Do any of you use any of these products at all? On a trip since you don't know what you're getting or all the time?
