I use sea foam in my lawnmower and weed wacker. It seems to cut through the gunk from reformulated gas. I have also put it in the tank of some old British cars I have. Seems to make them run smoother after a winter in the garage. Never used it in the Boxster. Is my memory deceiving me or was there a discussion years ago about people using techron fuel injection cleaner in their boxsters and loving it?
