During its 40+ years of existence, customers of the "Green Oil" have consistently reported an immediate difference with their application(s) after making the switch to PennGrade 1. Specific examples include the maintaining of oil pressure, cooler running engines during operation and valve train noise reduction. The steady oil pressure and cooler / quieter operation can be attributed to the body of the base oils in PennGrade 1 products, where the unique inherent traits of film strength, high VI and thermal / oxidative stability are combined.
It is critical that high performance lubricant customers chose a lubricant supplier with years of experience in blending high performance lubricants that are tested and endorsed by component manufacturers and engine builders alike. The refinery producing PennGrade 1 has been blending high performance lubricants since 1967 and through those years developed balanced products to provide maximum protection to engine parts during high engine torque loading and/or periods of heavily stressed operation. Consistent high quality and performance, exceptionally strong film strength and superior metal wetting characteristics are the properties that distinguish PennGrade 1 products from their "me too" industry counterparts. Combining the benefits of PA grade base oils with select additive technology that offers the full complement of "enhanced" anti-wear protection needed for cams (including flat tappet cams), lifters, bearings and other critical engine parts results in accolades from engine builders, racers and enthusiasts alike. Those directly associated with PennGrade 1 stand proudly and firmly behind each and every one of their products. When correctly utilized in applications for which they are specifically designed and recommended, PennGrade 1 can be used with the highest level of confidence and assurance.
