Feel the Difference

The most common comment Royal Purple® receives from customers is how they can feel the difference in their car's performance. Though performance gains will vary depending on the type of vehicle, its condition, and the way it’s driven, Royal Purple® provides superior protection and typically creates horsepower and torque gains up to 3%, fuel consumption reductions up to 5% and emission reductions of more than 20%.

Visit the test summary page for independent test results that document these performance gains.

Superior Technology

Synerlec® is the cornerstone of Royal Purple's automotive products. Synerlec® is Royal Purple's proprietary, lubricant technology that strengthens the oil to provide unmatched real-world performance and protection.

Reduce Friction, Improve Performance

The primary purpose of oil is to reduce friction. Reducing friction increases horsepower and torque, and reduces fuel consumption, emissions, engine wear and heat.

Royal Purple® continuously protects because it continuously adheres to metal parts—even after shutdown. Royal Purple withstands metal-to-metal contact because of its high film strength—a derivative of Synerlec®. By definition, film strength is a lubricant property that acts to prevent scuffing or scoring of metal parts. Royal Purple's film strength is up to 400% stronger than other oils.

Further Reduce Friction, Further Increase Performance

Royal Purple micro-polishes metal surfaces to further reduce friction and increase performance. Take a look at the following photos:

Notice that after using Royal Purple® the bearing surface is now significantly smoother than it originally was. Smoother surfaces reduce friction.

Increase Oil Life, Increase Savings 

Often lubricants have a service life of only 3,000 miles due to oxidation which reduces oil's ability to lubricate. Oil's ability to resist oxidation is measured by the ASTM's rigorous Thin Film Oxidation Uptake Test (TFOUT). Royal Purple surpasses leading mineral- and synthetic-based oils in this test and also outlasts the duration of the test.

Royal Purple's superior oxidation stability enable oil changes to be extended to 12,000 miles, saving money, saving time and reducing the amount of used oil that must be disposed of.
