Royal Purple® Motor Oil is a tough, long life, high performance oil that delivers superior protection and enhanced performance to gasoline and diesel engines. It gains its performance advantages from a blend of synthetic oils plus Royal Purple's proprietary, synthetic Synerlec® additive technology.

Synerlec® additive technology greatly reduces engine wear, including ring, cylinder and bearing wear. It is extremely tenacious, adheres to engine surfaces and remains after shutdown, which provides protection upon initial startup.

Multi-Grade Oils: 5W20, 5W30, 10W30, 10W40, 15W40, 20W50

Straight-Grade Oils: SAE 30, SAE 40, SAE 50



Royal Purple's motor oils are API certified and will not void new car warranties. Royal Purple® recommends waiting until the manufacturer's first scheduled oil change or a minimum of 2,000 miles in new gasoline engines before using Royal Purple®. Allow 8,000 to 10,000 miles before use in diesel engines.


Royal Purple® Motor Oils are compatible with other mineral and synthetic motor oils.

Environmentally Responsible: Royal Purple® Motor Oil extends oil drain intervals, eliminates premature oil changes, decreases the amount of oil purchased and disposed of and conserves energy.

Royal Purple's relentless pursuit of excellence within the lubricant industry consistently produces a reputation associated with quality and superior performance in both automotive and industrial markets.

Try Royal Purple® today and see why it truly is the performance oil that outperforms™.
