Yes. Royal Purple’s lubricants can be used with exotic fuels. For the best protection, Royal Purple has formulated its XPRspecifically 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.
