High Performance Motor Oil

Royal Purple® combines premium synthetic base oils with proprietary additive technologies to exceed protection and performance requirements of new modern engines. These often include smaller displacements, turbo chargers, gasoline direct injection (GDI), and start/stop systems. Modern gasoline direct injection (GDI) engines have achieved levels of power and fuel economy never before possible in passenger car engines. As a result, smaller engines operate at much higher loads across all engine speeds. This has caused increased wear in critical areas of the engine, and created a destructive phenomenon called low-speed pre-ignition (LSPI). The unique, state-of-the-art additive technology in Royal Purple High Performance engine oils is designed specifically to address these issues, and help engines maintain performance and reliability.


  • 300% BETTER OXIDATION RESISTANCE** – Maximum protection from oil breakdown. 
  • 100% LOW SPEED PRE-IGNITION PROTECTION**◊ – Prohibits major damage to cylinder walls, pistons, piston rings, connecting rods and spark plugs, maximizing engine life.
  • 50% IMPROVED DEPOSIT CONTROL** – Removes power robbing deposits for like new performance
  • 14% ENHANCED SLUDGE PROTECTION** – Cleaner engines operate more efficiently, lowering operating temperatures

royal purple max gear


Max Gear is a high performance automotive gear oil designed to provide maximum protection to heavily loaded gears while increasing power throughput through the drive train. Max Gear virtually eliminates both gear and bearing wear— even under severe squeeze film conditions caused by extremely high loads, sudden shock loads or low RPMs. Slippery, synthetic molecules not only reduce wear and friction but significantly increase Max Gear’s cold weather fluidity and lubricity, making it the ideal choice for vehicles operating in cold climates. Gears run smoother, quieter, cooler and longer without overhauls. It is noncorrosive to both ferrous and nonferrous metals.


  • Maximizes horsepower Extends gear and bearing life Reduces operating temperature
  • Lower coefficient of friction
  • Superior corrosion protection
  • Separates rapidly from water For use with open, limited-slip and locking differential Contains limited-slip friction modifier

royal purple synchromax


Royal Purple® Synchromax® is recommended for manual transmissions that specify an automatic transmission fluid or other light-viscosity oil. It is also ideal for transfer cases and 2-cycle motorcycle gear boxes that specify light viscosity lubricants. Synchromax is formulated with Royal Purple’s synthetic, proprietary Synerlecadditive technology, offering improved shift quality over a wide temperature range and reduced gear noise. Synchromax is fully compatible with all types of friction materials and offers excellent corrosion and oxidation protection without affecting the soft metals commonly found in manual transmission synchronizers.


  • Greater wear protection
  • Smoother shifts 
  • Excellent rust / corrosion protection 
  • Reduces friction for more power
  • Lowers operating temperatures 
  • Can be used as a replacement for Auto-Trak II, VersaTrak® and Synchromesh

royal purple max cycle


Royal Purple® Max-Cycle® is specifically formulated to exceed the demands of highly stressed engines and transmissions. It is recommended for use in both air-cooled and liquid-cooled 4-cycle engines and is compatible with wet-clutch transmissions. Formulated with select synthetic base oils and Royal Purple’s proprietary Synerlec® additive technology, Max-Cycle provides improved film strength when compared to the leading synthetic and mineral oil. Its shear stability and oxidation resistance promotes greater performance and protection. Max-Cycle meets or exceeds API requirements and is rated JASO MA2, the highest wet clutch compatibility rating under the JASO T903:2011 Clutch Friction Test.


  • Greater wear protection
  • Cleaner, more efficient engines 
  • Superior rust / corrosion protection
  • Cooler operation and less parasitic power loss
