GRANITIZE® Motor Oil Supplement is specially formulated to fortify both conventional and synthetic engine oils. Special additives prevent oil oxidation and protect vital engine components from wear, sludge, and corrosion. Granitize M.O.S.® provides protection for today’s high performance engines.
Today’s engines operate under severe temperature extremes and are engineer- ed with close tolerances, variable valve controls, and other systems that are sensitive to crankcase deposits. These factors combined with manufacturer’s extended oil drain intervals, create a difficult environment for even the high- est quality synthetic oils which can break down and form deposits. 11 fl. oz.
