Description
Product Description
Shell Spirax S4 CX 10W is a premium heavy-duty transmission and hydraulic oil specifically developed for off-highway equipment. Formulated with high-quality mineral base oils and an advanced additive system, it is designed to provide excellent protection for powershift transmissions, torque converters, final drives, oil-immersed (wet) brakes, and hydraulic systems operating under severe service conditions. It is recommended for equipment manufactured by Caterpillar, Komatsu, and other leading OEMs requiring a TO-4 performance lubricant.
The shear-stable SAE 10W formulation delivers excellent wear protection, stable friction characteristics, reliable brake performance, oxidation resistance, and long equipment life, ensuring dependable operation in construction, mining, quarrying, and earthmoving applications.
