Torco SGO 75w140 Racing Gear Oil Bottle - 1 liter is designed to maximize power efficiency and provide the highest level of gear protection under the most severe speed and load conditions. It is formulated using a combination of group IV/V synthetic base oil chemistries and additive technologies providing high shear resistance and 4-5 times the film strength of conventional oils. This combination of base oils and extreme pressure chemistries offer superior wear protection, improved power throughput, longer component life and prevents rust and oxidation. It is recommended for use in differentials, transmissions and transfer cases requiring an SAE 70W90, 75W90, 80W90 or 90 GL-5 or GL-6 rated gear oil. It is used in all forms of racing and performance street applications. It is highly recommended to optimize power efficiency and extended drain intervals.
