"I add one of these at every oil change and have noticed a quieter engine during startup and approx 1mpg increase in fuel mileage.....Awesome stuff!" - Mike
Super Lube Engine Treatment contains Syncolon (PTFE) resins which attach to critical friction surfaces, especially cylinder walls and bearings. Super Lube Engine Treatment protects your engine during cold starts when even the best motor oils are not effective. One treatment protects for more than 50,000 miles. It reduces engine wear and can be used in both diesel and gasoline engines.
