PennGrade 1 Engine Oil 71176; Nitro 70 70W ZDDP Enhanced - 10 Quarts

Specifically formulated for gas, alcohol, and nitromethane fueled engines that experience extreme torque, load, and high temperature conditions. The initial high viscosity of “Nitro” 70 allows excessive dumping of fuel “blow by” into the lubricating fluid while maintaining critical protection for expensive, high performance racing engines and their components. Delivers excellent shock load and high temperature protection to heavily stressed engine parts including bearings, camshafts, rings, and pistons. Good anti-foaming and shear stability characteristics, excellent high temperature protection from thermal breakdown, outstanding film strength, and strong anti-wear properties. Size - 10 Quart
