Max ATF is a synthetic, high-performance, automatic transmission fluid. Its low co-efficient of friction and high film strength help dramatically reduce heat and wear. Additionally, our premium ATF fluid gives you longer fluid life because it’s more oxidation-stable than other transmission fluids. Thus a longer lasting synthetic transmission fluid can result in a number of advantages. Most often, Royal Purple customers report crisper shifting, improved fuel economy and increased power with Max ATF. Max ATF is scientifically engineered to extend the life of your transmission by reducing heat and wear on your transmission system. Automatic transmissions generate a great deal of heat and depend upon transmission fluids for cooling and protection. More than 90 percent of all automatic transmission failures are caused by overheating. As a result, a 20°F reduction in fluid temperature can double the life of the transmission (Source: Perma Industries, Inc.). Max ATF is fully compatible and can be mixed with other automatic transmission fluids. However, for the best results, drain or flush the current transmission fluid and then fill with Max ATF synthetic transmission fluid.
