Professional engine builders and race teams have cited increased
horsepower and torque, and longer engine life with the use of Royal
Purple. According to multi-year IHRA Top Fuel Champion
Clay Millican, When we began using Royal Purple, I couldnt believe
the difference. Run any oil back to back with Royal Purple and
youll see a difference.
Independent tests on racing engines show as much as an 80%
reduction in wear by using Royal Purples XPR oils
compared to other racing oils.
XPR combines the highest quality synthetic base
oil, Royal Purples proprietary Synerlec additive technology and
additional performance enhancers to create a lubricant that
maximizes horsepower and torque, while providing the highest level
of protection against heat and wear. XPR provides more
protection than conventional motor oils mineral or synthetic
including those combined with aftermarket additives.
Be sure to follow the manufacturer and / or engine builders
recommendations when selecting oil viscosity. Please contact our
