Royal Purple formulates its Ultra Performance Lubricants™ to maximize performance in real world applications. Numerous independent tests report performance gains by using Royal Purple lubricants. Results using Royal Purple products vary depending on the type of vehicle, its condition, and the way it’s driven.


I have a 2002 Nissan Frontier Crew-cab V6 that only got 19 mpg until I started using Royal Purple. Now I get 23 mpg, my truck runs better than it did new and it has 74,100 miles on it. I started using Royal Purple 10W30 at 30,000 miles. I’ve told all my friends if they don’t try Royal Purple, they will regret it. THANK YOU.Gary Reeves

Advanced Technology Creates Advanced Products

Synerlec® additive technology is Royal Purple’s most versatile additive technology and the cornerstone of our product line. Synerlec enables our products to significantly outperform ordinary synthetic conventional lubricants. This proprietary additive technology improves our products on a molecular level, by creating high-strength ionic bonds with metallic surfaces that allow our lubricants to react to sustained heat and pressure with increased film strength and lubricity.

High Film Strength Improves Performance

The film strength of a lubricant is its inherent ability to withstand the effects of load, speed and temperature without breaking down or rupturing, thus enabling the lubricant to maintain an unbroken film between lubricated surfaces under operating conditions. Royal Purple’s Synerlec-enhanced product’s provide exceptional film strength and improves combustion to free up more power, optimize fuel economy and reduce emissions. High film strength also dramatically reduces wear.

According to the editors of Hot Rod Magazine, “We’ve torn down some of our dyno engines that have been seriously abused, but with Royal P(urple) in the pan, the bearings have looked new.”

Royal Purple Synerlec-enhanced product’s actually improves the condition of metal surfaces by remaining long after pressure would have been squeezed out of ordinary lubricants. Royal Purple responds to increased pressure with increased viscosity. Take a look at the following photos:
