It's "The Green Oil" made in the USA
Pennsylvania Grade 1® High Performance Oil with Zinc.
SAE 30 mono-grade oil formulated specifically to meet the critical lubrication needs of new engines during break-in, while allowing proper seating of rings and component ‘run-in’. Enhanced levels of “zinc” (zinc dialkyldithiophosphate a.k.a. ZDDP), and a superior oil film strength, offer superior anti-wear and anti-scuffing protection for street and/or racing engines with ‘flat tappet’ cams during break-in.
Brad Penn Performance Oils offer excellent shock load and high temperature protection for heavily stressed engine parts, including bearings, camshafts, rings, and pistons. It reduces internal friction, allowing for increased horsepower output, while maintaining a strong lubricating film protection under the most demanding torque and extreme temperature conditions. These high performance formulations provide excellent antifoaming and shear stability characteristics, exceptional high temperature protection from thermal breakdown, superior film strength, and strong anti wear properties.
