PENN-GRADE 1® High Performance Oils PENN-GRADE 1® 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.

Penn Grade 1® High Performance Oils The term “100% Pure Pennsylvania Grade Crude Oil” has long carried with it an industry connotation for being one of the best sources of high quality lubricant base stocks in the world. Our BRAD PENN® refinery, the oldest continuously operating lube oil refinery in the United States, still refines 100% Pennsylvania grade crude oil. PA grade crude oil is a very thermally stable paraffinic crude oil which contains no asphaltic constituents. This makes it an ideal choice from which to refine premium quality base oils. Because we use only one crude stock, our refined products are of consistently high quality and performance. BRAD PENN® brand products are truly “MADE IN THE U.S.A.” American Refining Group’s Bradford, PA refinery is the home of “The Green Oil®” that racers, engine builders and enthusiasts alike have all come to know and love! The unique green color and outstanding performance of our Penn Grade 1 High Performance Oils set them apart from the competition. Penn Grade 1® High Performance Oils are formulated using a unique base oil cut from our tower, which gives our Penn Grade 1® High Performance Oils exceptional film strength. This unique base oil causes our Penn Grade 1®High Performance Oil to cling tenaciously to engine parts to minimize wear during high engine torque loading and/or periods of heavily stressed operation such as those experienced during competition. This same oil ‘cling’ helps prevent ‘dry-start’ conditions to minimize wear even after the engine has been sitting idle for extended periods. Penn Grade 1® High Performance Oils also contain highly effective detergent and dispersant additives to guarantee exceptional engine cleanliness as well as oxidation and foam inhibitors that offer protection against thermal degradation and air entrainment. In addition to our unique base oil cut, increased concentration of “zinc” (zinc dialkyldithiophosphate a.k.a. ZDDP) provides outstanding anti-wear/anti-scuffing protection for engines employing either ‘flat tappet’ or roller cams. Penn Grade 1® High Performance Oils have been evaluated by a number of premiere camshaft manufacturers with tremendous success. Many are now recommending our Penn Grade 1® High Performance Oils to provide outstanding protection for their ‘flat tappet’ or roller cams.
