Royal Purple - Premium Synthetic Oil

Founded in 1986 by synthetic lubrication pioneer John Williams in Porter, Texas, Royal Purple specializes exclusively in high-performance synthetic motor oils, gear fluids, greases, and industrial lubricants. Their hallmark additive technology, Synerlec, delivers superior film strength, wear protection, and horsepower gains, outperforming traditional mineral and synthetic blends.

Royal Purple’s product suite spans consumer and industrial applications, from dexos1™‑approved street oils to XPR® Extreme Performance Racing lines used in NASCAR, NHRA, World of Outlaws, and marine racing—each rigorously tested for heat resistance, longevity, and extreme fuel compatibility.

Grown from industrial roots to global presence, Royal Purple operates ISO‑certified production, distributing to over 25,000 outlets worldwide before its acquisition by Calumet in 2012. With formulators boasting over 200 years of combined expertise, the brand remains committed to lubricant innovation and continuous performance leadership.

Whether on the street, strip, or factory floor, Royal Purple delivers engineered lubrication solutions that elevate efficiency, protect assets, and maximize performance.
