Shell Spirax S4 TX
Shell Spirax S4 TX is a premium performance Super Tractor Oil Universal (STOU) developed to provide reliable lubrication across a wide range of agricultural equipment applications. Formulated using Shell’s advanced XHVI base oil technology combined with a carefully balanced additive system, the lubricant delivers excellent performance in engines, transmissions, hydraulic systems and other mechanical components used in modern agricultural machinery. The multi-functional formulation allows a single lubricant to be used across multiple systems within farm equipment, helping simplify maintenance and lubrication management.
One of the key advantages of Shell Spirax S4 TX is its versatility. As a universal tractor oil, the lubricant can be used in many lubrication points across agricultural machinery including engines, transmissions, hydraulic systems and power steering units. This reduces the need for multiple lubricants across the farm and helps simplify equipment servicing and inventory management while maintaining reliable lubrication performance.
Shell Spirax S4 TX also provides excellent protection against wear and mechanical stress. The advanced additive technology combined with shear-stable viscosity performance helps maintain a strong lubricating film between metal surfaces. This helps prevent metal fatigue and reduces wear on critical components such as gears, bearings and hydraulic pumps. By protecting these components from damage, the lubricant contributes to longer equipment life and improved reliability during demanding agricultural operations.
Another important benefit of Shell Spirax S4 TX is its excellent engine cleanliness and deposit control. The use of Shell’s XHVI base oil technology reduces the need for viscosity improving polymers that can negatively impact engine cleanliness. As a result, the lubricant helps maintain cleaner engines and internal components, contributing to improved engine efficiency and longer service life for agricultural machinery.
Shell Spirax S4 TX also delivers excellent low-temperature performance and hydraulic responsiveness. The SAE 10W-40 viscosity grade provides improved fluidity at lower temperatures compared with heavier tractor oils, allowing rapid oil circulation during cold start conditions. This helps reduce wear at start-up while supporting responsive hydraulic operation and smooth system performance in varying operating environments.
The lubricant is recommended for use in a wide range of agricultural equipment applications including tractor engines, transmissions, hydraulic systems, oil-immersed brakes, powershift transmissions, hydrostatic transmissions and conventional gear drive systems. It meets key industry and manufacturer specifications including Massey Ferguson M1139 and M1145, John Deere JDM J27, Caterpillar TO-2 and ZF TE-ML 06B, 06D, 06F, 06N and 07B. The product also meets API GL-4 gear oil requirements and can be used where API CF-4 or API SF engine oil performance levels are specified. Physical characteristics include a kinematic viscosity of approximately 85 mm²/s at 40°C and 14.1 mm²/s at 100°C with a viscosity index of approximately 172. The oil has a density of approximately 850 kg/m³ at 15°C, a flash point of approximately 220°C and a pour point of approximately –36°C.
