Gear Oil
Castrol multi-grade gear oils are designed to withstand the demanding conditions of transmissions, transfer cases, and differentials in automobiles, trucks, and other machinery. A balanced formulation maintains viscosity protection at high temperatures while maintaining excellent low temperature properties to insure flow and distribution of oil in the coldest conditions. Castrol gear oils utilize premium gear oil technology to deliver excellent anti-wear, anti-scuff, and extreme pressure performance. All Castrol Gear Oils exceed API Service GL-5 to deliver in the most severe extreme pressure situations.
