Wynns Engine Transmission Stop Leak
Wynns Engine Transmission Stop Leak is an oil additive for the crankcase, differential or manual gearbox. It is a seal rejuvenator and viscosity index improver for duel action leak prevention. Swells and nourishes all hardened or shrunken rubber, Nitrile, NBR, Silicone, Fluoroelastomer or Polyacrylate oil seals to stop oil seepage. The VI Improver prevents oil thinning as engine temperature increases, preventing oil from passing past the rings into the combustion chamber where it burns out producing smoke.
