Royal Purple manufactures high-performance lubricants and fluids for automotive, industrial, marine, and motorcycle applications. They offer a wide range of conventional and synthetic oils, gear oils, and fuel and coolant additives, to name just a few.
Synerlec® additive technology is Royal Purples 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.
