Mobilfluid 428 is a modern extra high performance multipurpose tractor lubricant engineered to meet or exceed the requirements of most equipment builders for hydraulic and transmission compartments. It is designed to optimize the performance of agricultural and commercial tractors operating in a wide range of environments and conditions. Mobilfluid 428 is recommended to be used in off-highway industries including: agriculture, construction, and quarrying. Its friction characteristics helps reduce wet brake and Power Take-Off (PTO) chatter. This next generation product is formulated from high quality base oils and advanced additive technology to deliver excellent thermal stability combined with high shear stability for an SAE 10W-30 viscosity grade. Based on the excellent shear stability and air handling, Mobilfluid 428 is suitable for use in conventional CVTs (hydraulic pump plus planetary gear componentry).
