PennGrade 1 High Performance Oil is specially formulated to meet the stringent lubricating demands of high-performance, highly stressed, street and racing engines. It delivers excellent shock load and high temperature protection to heavily stressed engine parts including bearings, camshafts, rings, and pistons. It reduces internal friction for increased horsepower output while maintaining its strong lubricating film protection even under the most demanding torque and extreme temperature conditions. It also provides good anti-foaming and shear stability characteristics, excellent high temperature protection from thermal breakdown, outstanding film strength, and strong anti-wear properties. It is formulated with a typical TBN of 10.6 to provide a high level of detergency for protection against bearing corrosion and piston deposits in both turbocharged and non-turbocharged engines.
