Royal Purple Motor Oil delivers superior protection and improves performance in four-cycle gasoline and diesel engines. It increases horsepower and torque, saves fuels and reduces heat, wear and emissions. It has unsurpassed oxidation stability that allows for extended oil drains and fewer oil changes, which saves you time and money and reduces the impact on the environment.
Royal Purple’s performance advantages come from a blend of synthetic oils plus Royal Purple’s proprietary Synerlec technology. Royal Purple Motor Oil is compatible with other mineral and synthetic motor oils.
Max ATF is a synthetic, high-performance, automatic transmission fluid. Its low co-efficient of friction and high film strength help to dramatically reduce heat and wear. Additionally, Max ATF is more oxidation stable than other transmission fluids for longer fluid life.
Max ATF is recommended for a wide variety of transmissions. See our transmission lubricant cross reference chart for specific applications.
Max ATF significantly reduces heat to extend the life of your transmission. Automatic transmissions generate a great deal of heat and depend upon the transmission fluid for cooling and protection. More than 90 percent of all automatic transmission failures are caused by overheating; 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 oil and then fill with Max ATF.
Max-Gear is an ultra-tough automotive gear oil. It’s designed to maximize power and provide unsurpassed protection to heavily loaded gears. It makes gears run smoother, quieter, cooler and longer without overhauls.
Max-Gear outperforms other gear oils because it combines the highest quality synthetic oils with Royal Purple’s proprietary Synslide additive technology.
Max-Gear is recommended for use in truck, motor home / RV, and automotive front or rear differentials, manual transmissions, and lower gear units of marine engines that specify use of an API GL-5 or GL-4 fluid. All viscosities of Max-Gear are formulated with hypoid friction modifiers necessary for use in clutch or cone type differentials. No additional additives are necessary.
Engine builders have grown increasingly concerned that many modern motor oils do not provide adequate wear protection for new engines, particularly those using flat-tappet cams. Royal Purple has addressed this issue by developing a new engine break-in oil.
Royal Purple Break-in Oil is formulated to allow optimal ring seal and protect rotating assembly components such as the camshaft and valve train from initial start up wear. Royal Purple combines highly refined mineral oil, preferred for engine break-in, with advanced additives containing high levels of zinc and phosphorus to optimize protection in flat-tappet and roller engines.
Royal Purple Break-in Oil is fully formulated and does not require the use of any other chemical additives. Royal Purple recommends using their high performance motor oils after the engine is broken in for maximum engine performance.
