Shell Spirax S4 CX 10 , 30 , 50 - 209 LT

BENEFIT SAE 10W TO-4 Heavy-Duty Transmission and Hydraulic Oil. This is a premium, high-performance off-highway transmission and hydraulic fluid engineered specifically for severe-duty applications. It provides critical shear stability because it is formulated purely from high-quality base oils without the use of viscosity index (VI) improvers, protecting heavily loaded machinery parts from friction and mechanical breakdown. Key Specifications Viscosity Grade: SAE 10W (SAE J 300). Core Performance Standard: Caterpillar TO-4 (strictly mandates specific friction and anti-wear controls). Industry Approvals: ZF TE-ML 03C, Allison C-4 (suitable for use). Kinematic Viscosity: ~36 mm²/s at 40°C / ~6 mm²/s at 100°C. Pour Point: -36°C (ensures fast system response during cold-weather startups). . Documents Technical Data sheet
