Yes. Royal Purple’s lubricants can be used with exotic fuels. For the best protection, Royal Purple® has formulated its XPR®specifically with this in mind. The XPR oils are formulated to combat fuel emulsification to hold up even better than Royal Purple’s other engine oils in alcohol and methanol applications. Royal Purple Nitro Plus™ oils are the best choice for blown alcohol, Nitro-methane and any other race application with excess fuel dilution. Royal Purple’s other synthetic engine oils will still perform better than conventional racing oils; however, significant fuel dilution will reduce the effectiveness of these oils much more than the XPR and Nitro Plus oils.
Royal Purple API-licensed motor oils are formulated to provide unparalleled performance and protection while complying with API and ILSAC specifications. XPR and Nitro Plus racing oils vary in viscosity and formulation from the API-licensed motor oils to provide the greatest performance and protection possible, without regard to API, ILSAC, or OEM specifications.
We do not restrict any automotive product from any retailers that carry Royal Purple consumer products. Any lack of availability of Royal Purple products at local retail stores is due to the choices made by the store owners/buyers. Retailers choose the products they stock and order for a myriad of reasons. Many times, a local retailer will special order Royal Purple products if you can provide the part number. Another option is to shop online. Several online retailers, including Amazon.com, JEGS.com, Lucky7Trucks.com, PacePerformance.com, and SummitRacing.com carry just about all Royal Purple automotive and consumer products, and they will ship directly to you.
No. Royal Purple has not found any evidence that it shows deterioration in performance after being subjected to race conditions. Excessive fuel dilution may effect the performance of any engine oil; however, XPR and Nitro Plus oil offer greater protection than other oils even with excessive fuel contamination.
