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 motor oils for passenger cars and trucks are API licensed. For those seeking enhanced performance in high performance vehicles not under warranty, we recommend our XPR – Extreme Performance and Racing motor oil.
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. Phone 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.

Synchromax is a manual transmission fluid that increases performance and the life of your equipment. It improves shifting, reduces gear noise and increases power transfer to the wheels. It also lowers operating temperatures and provides outstanding wear protection for longer transmission life.
Synchromax is recommended for manual transmissions that specify an automatic transmission fluid. It’s also ideal for 4×4 transfer cases and motorcycle gear boxes. Synchromax is fully compatible with all types of friction materials. It provides excellent corrosion and oxidation protection without affecting the soft metals commonly found in manual transmission synchronizers.
Synchromax is formulated with Royal Purple’s proprietary Synerlec technology for unsurpassed performance and protection.

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.
