PennGrade 1® Partial Synthetic SAE 20W-50 High Performance Oil - Case of 12 - 1 Quart Bottles

Designed to offer higher performance engines the cold temperature operational benefits of an SAE 20W' engine oil while providing the desired film strength; sealing abilities; bearing, crankshaft, piston ring and valvetrain component anti-wear protection of an SAE 50 weight oil at normal engine operating temperatures.

PENN-GRADE 1(R) High Performance Oils are specially formulated using high quality PENN-GRADETM base stocks and select additive technologies to meet the stringent lubricating demands of high-performance, highly stressed, street and racing engines. They deliver excellent shock load and high temperature protection to heavily stressed engine parts including bearings, camshafts, rings, and pistons. They reduce internal friction allowing 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 excellent antifoaming and shear stability characteristics, exceptional high temperature protection from thermal breakdown, superior film strength, and strong anti wear properties.

Please Note: Penn Grade 1 High Performance Oils contain high zinc and phosphorous additive concentrations which can be detrimental to cars and trucks with catalytic converters.
