PennGrade1® Multi-Grade High Performance Oils are specially formulated using high quality PennGrade base stocks and select additive technologies to meet the stringent lubricating demands of high-performance, highly stressed, street and racing engines. PennGrade 1® Partial Synthetic High Performance Oils deliver excellent shock load and high temperature protection to heavily stressed engine parts including bearings, camshafts, rings, and pistons. They reduce internal friction for increased horsepower output while maintaining their strong lubricating film protection even under the most demanding torque and extreme temperature conditions. These high performance formulations also provide good anti-foaming and shear stability characteristics, excellent high temperature protection from thermal breakdown, outstanding film strength, and strong anti-wear properties.

PennGrade® Motor Oil is built from the legacy of PennGrade 1® High Performance Motor Oil, or “The Original Green Oil®”. PennGrade 1® uses a unique base oil cut from Pennsylvania Grade Crude Oil. The oil has a unique green color and the ability to stick and cling to metal parts, offering full film strength and prevent excess wear caused by dry startups. Its enhanced levels of zinc and phosphorous (ZDDP) protect vital engine components such as “flat tappet & roller cams”, and it has been the first choice of engine builders and automotive manufacturers for decades.
