Royal Purple Extreme Performance and Racing (XPR) Synthetic Oil - Racing 51 XPR 20w50, Quart Size, Pack of 12 Review

Average Reviews:

(More customer reviews)I own a 2008 Jeep Grand Cherokee SRT8 with an Arrington 426 Hemi engine rated at 607 horsepower on an engine dyno. Royal Purple was recommended by Arrington and I only use the recommended 20W-50 XPR in my engine year around. Call Royal Purple and speak to an engineer about your application, you'll be glad you did!

Average Reviews:

(More customer reviews)Royal Purple is the best oil for any engine. The XPR (Extreme Performance and Racing) line is the best of the best! I use the XPR in my 426 Hemi engine, which sees hard use on the street and at the track. Not sure what oil is best for your engine? Call the engineers at Royal Purple and they will be glad to make a recommendation for your specific need.
