The Penn Grade 1® Partial Synthetic SAE 20W-50 is 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.
BRAD PENN PENN-GRADE 1 Multi-grade High Performance Oils are specially formulated using high quality PENN-GRADE
base stocks and select additive technologies to meet the stringent
lubricating demands of high-performance, highly stressed, street and racing engines.
BRAD PENN PENN-GRADE 1 Multi-grade 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 antifoaming and shear stability characteristics, excellent high temperature protection from thermal breakdown, outstanding film strength, and strong antiwear properties.
Penn Grade 1 High Performance Oils contain high zinc and phosphorous additive concentrations which can be detrimental to cars and trucks with catalytic converters. Always consult your owner's manual for proper oil selection.
