Apply to cam lobes, lifter faces, bearing journals, distributor gear, and any sliding/rotating surface that won't see pressurized oil instantly on first crank.

Vehicle Fitment

• Universal: Apply to any engine during assembly or rebuild — air-cooled VW and classic engine builds included.

Why Choose PennGrade 1?

PennGrade 1 is the modern brand name for the legendary "Brad Penn" green oil — refined in Pennsylvania from paraffinic crude, with a high-zinc additive package (ZDDP) that has long made it the favorite of vintage, air-cooled, and flat-tappet engine builders. Made in the USA.
