Proper engine lubrication during assembly and break-in after a full rebuild or a cam and lifter swap is important for the engine’s overall life and performance. That involves a three-step process using high-quality assembly lubricant, break-in oil and motor oil like those made by PennGrade 1 Oil.

The Break-in and High Performance Motor Oil is available in quart bottles or super-handy five-quart jugs that are more convenient to use and cost less than buying five single quarts. It’s nice to have choices.

PennGrade 1 Break-In Oil is a SAE 30-weight oil formulated with premium base stocks and a state-of-the-art additive system robust with high levels of zinc dialkyl dithiophosphate (ZDDP). This helps prevent metal-to-metal contact and premature wear of critical engine parts. That allows the engine components to seat properly for maximum engine performance and life.


Once your engine is broken in, keep it protected with PennGrade 1 High Performance Motor Oil. It has strong detergents, dispersants, and ZDDP anti-wear additives to protect critical engine parts from deposits in highly stressed engines. It provides excellent shock load and high temperature protection for heavily stressed parts including bearings, camshafts, rings, and pistons.

PennGrade 1 oil also reduces internal friction for increased horsepower output and is available as a full synthetic in 5W30, 10W30, 10W40, 15W40 and 20W50 viscosities, or mineral-based in 30-, 40-, 50-, 60- and 70-weight viscosities.
