TOPGATEX 80W-90 Gear Lube is a multi-functional product designed to surpass the requirements of equipment and automotive applications calling for an SAE 80W-90 viscosity grade. Formulated base oil and high quality additives, TOPGATEX 80W-90 Gear Lube resists thermal breakdown. Its naturally high viscosity index and shear stable construction improves film strength and viscosity retention.
