High Performance Motor Oil API LICENSED MOTOR OIL Royal Purple High Performance Motor Oil combines premium base oils with proprietary additive technologies to create a high performance synthetic engine oil that optimizes performance and protection. Royal Purple High Performance Motor Oils carry the current API and ILSAC engine oil licenses, as well as the GM dexos1 gasoline engine oil approval. ILSAC GF-6 AND GM DEXOS1 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.

Product Features:

Better Wear Protection
Increased Protection against Low Speed Pre-Ignition
Increased Fuel Efficiency
Better Protection for Vehicle Exhaust Emissions Equipment
Improved Compatibility with Fuels Containing Ethanol
Superior Corrosion Protection

Max Gear is recommended for truck and automotive differentials, outboard motor lower units or in rear axles or manual transmissions requiring an API fluid. 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.

Product Features:

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
