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 1® Partial Synthetic High Performance Oils have a distinct green color and are available in (5) multi-grade viscosities to meet virtually all lubricating requirements of high-performance street and racing engines. The Partial Synthetic SAE 5W-30* is a low viscosity oil tailored to maximize horsepower in engines that use this type of engine oil and is ideally suited in today's street*/racing market 'crate engines’ that require this viscosity. Additionally, the 5W-30 contains strong detergent, dispersant and ZDDP anti-wear additives to help protect critical engine parts.
PennGrade 1® Partial Synthetic High Performance Oils SAE 10W-30*, SAE 10W-40*, SAE 15W-40* and SAE 20W-50* are 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. These engine oils provide outstanding "heavy load" bearing protection on heavily stressed engine parts. The synthetic component of these engine oils enhances the protection afforded at high and low temperature extremes. The 10W-30, 10W-40, 15W-40 and 20W-50 also contain strong dispersant and ZDDP anti-wear additives to protect critical engine parts.
