Penngrade 40w Racing Oil 1 Qt BPO71406

Engine protection under sustained high RPMs and extreme load cycles demands an oil engineered specifically for racing conditions—not just passenger-car duty. PennGrade 1 Racing Oil delivers the elevated zinc and phosphorous chemistry that racing engines require, with film strength that holds up when temperatures spike and bearing loads intensify. If you're serious about preserving engine longevity during track sessions or hard driving, this is the baseline protection your build needs.

This conventional 40W formulation has been the choice of engine builders and professional racers for decades because it performs consistently across a wide thermal range. The anti-foaming additives prevent aeration under aggressive cornering and high-speed runs, while the detergent package keeps critical engine surfaces clean even under extreme conditions.
