A synthetic gear oil of SAE 75W viscosity developed exclusively for racing transmissions. This grade has a naturally high viscosity index (ensuring good low temperature performance) and excellent shear strength, as well as possessing an inherently excellent load carrying capability. The synthetic materials used for this formulation have an oxidation stability of 3 to 4 times that of conventional mineral oils, prolonging the effective life of the lubricant under extreme working conditions. Coupled with this, the lower friction value leads to reduced pitting and wear of the gear teeth. PRO SRG 75 provides very superior protection and performance under the most demanding race conditions.
