Is the motor making noise or something? Maybe just do more frequent oil changes to clean up any sludge. If the engine has a lot of miles, sometimes removing sludge does more harm than good. I read a lot of testimonials online about Seafoam and other additives/cleaners, and they dont seem to really help. Rislone or seafoam can clean up a sticky lifter plunger.
But I wouldnt put that in my car. I would take it apart first. lol
