The TRUCKPRO 85W140 full synthetic gear/differential oil in a 55-gallon container provides lubrication aimed at reducing wear in heavy duty applications. Its enhanced thermal stability is designed to offer consistent performance under high temperatures. This oil features a high viscosity index, which maintains optimal flow across various operating conditions. It is suitable for high-load gear systems, minimizing metal-to-metal friction and thereby reducing noise and vibration for smoother and quieter operation.
