Wynns Engine Stop-Leak

Wynn's SupremeEngine Stop-Leak is formulated with a dual action package that reduces crankcase oil loss caused by both external leaks and internal combustion. This formulation improves the viscosity index and high temperature viscosity, controlling internal oil consumption while it conditions and gently swells rubber seals and gaskets, to stop and prevent external oil leaks. Engine l Stop-Leak also maintains excellent engine oil fluidity at low temperatures.

Advantages

  • DUAL ACTION FORMULA
    Proper engine lubrication is essential for a reliable, well-running vehicle. Two of the most common causes of rapid oil loss are external oil leaks and internal oil consumption. Wynn's Supreme Engine Oil Stop-Leak has an improved, dual action formula that reduces oil loss caused by both internal consumption and external leaks. This formulation improves the viscosity index and high temperature viscosity, controlling internal oil consumption while it conditions and gently swells rubber seals and gaskets, to stop and prevent external oil leaks.
  • COLD-CRANKING ABILITY
    During low temperature starts, Wynn's Supreme Engine Oil Stop-Leak maintains excellent engine oil fluidity. It will not reduce pump-ability or cold-cranking ability below freezing temperatures.

Wynn's Supreme Engine Oil Stop-Leak is designed to:
  • Reduce oil loss from external leaks and internal consumption.
  • Condition and gently swell rubber seals and gaskets, to stop and prevent external oil leaks.
  • Improve Viscosity Index and high temperature oil viscosity, to control internal oil consumption.
  • Maintain excellent engine oil fluidity at low temperatures.
