Not Ranked
Not to start an argument, but I will just stick with the STP. After using it for 20+ years with no problems I am to old to start trying everything that is recommended, and any company I call their's is the only one that will work according to them. I have used it in every engine from 4 cylindes to all out racing 427 tunnel ports and have never had a problem or found any deposits or problems when an engine had to be torn down. In fact a couple of the engine builders commented on how clean the regular driver engines were inside after all those miles.
