XP4 (15W-50) Joe Gibbs Racing Oil. A SAE 15W-50, petroleum version of our original formula race oil, XP4 offers lower cost protection for dirt and alcohol fueled engines that change oil after every race to prevent dirt and/or alcohol contamination. Designed for short duration races where engine load and dirt and fuel contamination is high, XP4 uses unique anti-wear additives and emulsifiers to fight engine wear and to trap dirt particles. Compatible with methanol and high octane race fuels. Recommended applications: Big block dirt late model V-8s, Sprint and Midget engines, and other race engines with main and rod bearing clearances over .0030. Viscosity typical of a SAE 15W-50.
