I blew a head gasket at 40K by incorrectly using STP Fuel System Cleaner. I was on a trip and "thought" it would be a good time the really clean the injectors, valves and pistons. I ran three treatments back to back instead only every 4K miles per instructions. The product works from personal experience but now I "do" follow the directions on the bottle.
