PennGrade 1® High Performance Oil Nitro 70

PennGrade1® “Nitro” 70 Monograde High Performance Oil is specifically formulated for gas, alcohol, and nitromethane fueled engines that experience extreme torque, load, and high temperature conditions. The PENN GRADE 1 ® SAE 50 and SAE 60 are suitable for use in gas, alcohol, and nitromethane fueled engines where these viscosities are desired. The initial high viscosity of these oils allows excessive dumping of fuel [“blow by”] into the lubricating fluid while maintaining critical protection for expensive, high performance racing engines and their components. Additionally, the SAE 60 is ideally suited for the heavier viscosity lubrication needs of the early classic motorcycles/engines like Harley Davidson® [Flathead®, Knucklehead®, Panhead®, Shovelhead®, etc.] and others. Always consult owner’s manual for proper oil viscosity and quality selection.
