Royal Purple Max ATF ® is a synthetic, high performance, long life, multipurpose, automatic transmission fluid. It's more oxidation stable than other transmission fluids for a longer fluid life. Max ATF's ® low co-efficient of friction and high film strength help to dramatically reduce heat and wear. Automatic transmissions generate a great deal of heat and depend on the transmission fluid for cooling and protection. More than 90 percent of all automatic transmission failures are caused by overheating.* A drop of 20°F in fluid temperature can double the life of the transmission.* Max ATF ® significantly reduces heat to extend the life of your transmission and is recommended for all automatic transmissions requiring Ford Mercon® or GM Dexron® III transmission fluids. Max ATF ® is fully compatible and can be mixed with other automatic transmission fluids; however, for the best results drain or flush the current oil and then fill with Max ATF ®.
