BRAD PENN® PENN-GRADE 1®
SAE 50 Racing Oil
Formulated with the unique cut from our Penn-Grade stocks, this heavy viscosity straight-grade motor oil is designed to provide excellent protection for street and competition engines. Its superior film strength, highly effective detergency package and foam inhibitors make it an optimal lubrication choice for muscle car/hot rod enthusiasts. The increased ZDDP provides outstanding antiwear/antiscuffing protection for engines with older style push rods as well as those employing flat tappet cams. Excellent option for vintage car lubricant and air-cooled applications where a mono-grade viscosity is preferred.
The Brad Penn® Penn Grade 1® Racing Oils contain the higher level of anti-wear (ZDDP - zinc dialkyldithiophosphate) and enhanced film strength so critical to proper high performance engine protection. The Penn-Grade 1® oils "typical" 1,500 ppm Zinc (Zn) and 1340-1400 ppm Phosphorus (P) content provide the needed anti-wear protection to critical engine parts, such as piston/cylinder walls, roller cams under heavy valve spring pressure and especially those that employ a solid "flat tappet" type system. As important as the chemistry is to the Penn-Grade 1® oils, it is by no means the whole story. The unique base oil cut used to refine the Penn-Grade 1® Racing Oils maintain a tremendous affinity to metal surfaces. This naturally occurring "metal wetting" characteristic enables the oil to stay put on your highly stressed engines and makes the Penn-Grade 1® Racing Oil resist slinging for an extended period of time. Also, rest assured in knowing that the Penn-Grade 1® Racing Oils are 100% Made in the USA.
