Does Royal Purple 2-Cycle oil void new engine warranties?August 17, 2018
Can I run your oils with exotic fuels (alcohol, methanol, etc.)?August 17, 2018
Yes. Royal Purple XPR® racing oils are fully formulated engine oils with complete additive packages needed for long-term use. The XPR ultra-light viscosity 0W-8 is considered suitable only for dedicated competition engines that are built specifically to use very low viscosity engine oils. Non-ultra light viscosities, XPR 0W-20, 0W-30, 5W-20, 5W-30, 10W-40 and 20W-50 may be used in street driven and daily driver applications, street and track duty vehicles and dedicated competition applications with gasoline or exotic fuels. Pleas note: Royal Purple XPR racing oils do not conform to API and/or ILSAC licensing requirements and should not be used when manufacturer’s warranties are an issue.
