PennGrade 1 Break-In Oil | Air-Cooled VW & Flat-Tappet Engines | SAE 30 High-Zinc, 1 qt (27-7120-6)

PennGrade 1 Engine Break-In Oil, SAE 30 — High-Zinc Cam Break-In (1 qt)

PennGrade 1 Engine Break-In Oil, SAE 30 — a dedicated break-in formula with elevated zinc and phosphorus levels engineered for the first 500-1000 miles of a freshly built engine. Critical for proper ring seating and flat-tappet cam break-in on air-cooled VW engines.

Vehicle Fitment

• Air-cooled VW (Type 1 / Type 2 / Type 3): Beetle, Bus, Karmann Ghia, Thing, and Type 3 — during engine break-in
• Any flat-tappet engine: Requiring elevated zinc/phosphorus for cam break-in after a rebuild

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.

Key Features & Benefits

• Elevated zinc & phosphorus: Engineered for the first 500-1000 miles of a freshly built engine.
• Flat-tappet cam protection: Required for proper break-in — running modern low-zinc oil through break-in will damage a freshly ground cam.
• Balanced anti-wear: Provides the right protection while still allowing the rings to seat properly.
• SAE 30 straight weight: Formulated specifically for the break-in period.

Frequently Asked Questions

• How long do I run break-in oil? Run it for the first 500-1000 miles after a rebuild, then drain and switch to regular PennGrade 1 multi-grade for normal service.
• Why not just use regular oil for break-in? Running modern low-zinc oil through break-in will damage a freshly ground cam. The elevated zinc/phosphorus protects the flat-tappet cam while still allowing the rings to seat properly.
