Its exclusive formula is proven to maximize engine life in cars, trucks, and SUVs with over 75,000 miles. Our mixture is specially developed with a unique combination of synthetic and premium conventional oils to protect your high-mileage motor against wear, friction, heat, and deposits – the four major causes of engine breakdown and expensive repairs. Anti-wear additives defend critical engine components, advanced friction-fighting agents reduce heat and abrasion, added detergents clean the inside of your engine, and premium seal conditioners handle aging seals to prevent leaks.
