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. It’s available in 0W40, 5W20, 5W30, 5W40, 10W30, 10W40, 15W40, 20W50, SAE 30, SAE 40 and SAE 50 weights.

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.

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.

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.

Please note: Max ATF is not recommended or an approved warranty replacement for: Aisin Warner AW-1, Ford Type F, Ford Mercon SP & Mercon LV, GM Dexron VI, Mercedes Benz MB 236.12 & 236.14, Shell M1375.4 (ZF 6-Speed AT) and Toyota WS. Max ATF is not recommended for use in any CVT applications.

Purple Ice is a high performance, synthetic, radiator coolant additive. It reduces engine heat by reducing the surface tension of the radiator fluids for improved heat transfer.

Purple Ice fosters optimum coolant flow by helping to prevent formation of scale deposits in the radiator. It also lubricates the water pump seals.

Purple Ice should always be used in conjunction with antifreeze in regions where freezing temperatures occur. Purple Ice is compatible with traditional ethylene glycol antifreeze (green) and GM Dex-Cool® antifreeze.

Extensive testing confirms Purple Ice reduces coolant temperatures better than similar products. For example, the average operating temperature of a 350 c.i.d. V8 engine (equipped with 160° thermostat) when dyno-tested with different coolants are:

Important Precautions: Be sure your cooling system is working properly and that the radiator is free of blockage and corrosion before using Purple Ice. Antifreeze should be properly mixed and filled to manufacturers' specifications. Distilled water and / or demineralized water should not be used if you elect to run a mixture of straight water and Purple Ice in your radiator. Contact Royal Purple’s Technical Support department if you are considering using Purple Ice with straight water or if you have previously used another brand of coolant additive.

Ultra-Performance Grease (UPG) is a high performance, multi-service, aluminum-complex, synthetic grease which significantly increases bearing life and equipment reliability. It also makes bearings run smoother, cooler and quieter.

UPG satisfies a wide range of grease requirements from the lubrication of bearings to u-joints and general-purpose use. It has outstanding extreme pressure capabilities and excellent water resistance to both emulsion and washout. UPG is stable at high temperatures. It also has excellent oxidation resistance for extended service life and to provide a margin of safety between lubrication intervals.

When the China Star Bullet Train was having heat problems keeping them from achieving optimal speed, they evaluated 26 of the best lubricants available.

After careful testing, senior engineers selected Royal Purple's Ultra-Performance Grease. Not only did Ultra-Performance Grease help them resolve their heat problems, it also, enabled them to set a new land-speed record for bullet trains.

UPG is made using a superior blend of synthetic base oils plus Royal Purple's unique, proprietary, noncorrosive Synslide additive technology.
