Shell Spirax S3 T
Shell Spirax S3 T is a premium performance universal tractor oil (STOU) developed to provide reliable lubrication across a wide range of agricultural equipment applications. Formulated using high viscosity index base oils and advanced additive technology, the lubricant is designed to deliver consistent performance in engines, transmissions, hydraulics and other mechanical systems used in modern farming machinery. This multi-functional oil helps simplify lubrication management by allowing a single lubricant to be used across multiple systems in agricultural equipment.
One of the key advantages of Shell Spirax S3 T is its versatility across a wide range of farming applications. As a Super Tractor Oil Universal (STOU), the lubricant can be used in tractor transmissions, hydraulic systems and other mechanical components that require reliable multi-purpose lubrication. This capability helps reduce the need for multiple lubricants across the farm, simplifying maintenance procedures and improving operational efficiency for agricultural operators.
Shell Spirax S3 T also delivers excellent protection against wear and mechanical stress. The advanced additive system helps protect gears, bearings and other working components from scuffing, pitting and wear during operation. By maintaining a strong lubricating film between metal surfaces, the oil helps reduce friction and protect critical components from premature wear and metal fatigue. This protection helps extend equipment life and maintain reliable machinery performance under demanding agricultural conditions.
Another important benefit of Shell Spirax S3 T is its ability to support smooth and responsive hydraulic system operation. The use of high-quality base oils with stable viscosity characteristics ensures reliable fluid flow across a wide range of operating temperatures. This helps ensure smooth operation of hydraulic pumps, valves and rams while maintaining precise control of hydraulic functions such as lifting and steering.
Shell Spirax S3 T also provides excellent protection against corrosion and contamination. The lubricant contains anti-corrosion additives that help protect metal surfaces from rust and oxidation, particularly in environments where machinery may be exposed to moisture or harsh operating conditions. This protection helps ensure long-term reliability of mechanical components used in agricultural equipment.
The lubricant is recommended for a wide range of agricultural applications including tractor transmissions, hydraulics, oil-immersed brakes, powershift transmissions, hydrostatic transmissions, conventional gear drive systems and power steering units. It meets several key industry and manufacturer specifications including Massey Ferguson M1139, M1144 and M1145, Caterpillar TO-2, John Deere JDM J27 and ZF TE-ML 06B, 06Q and 07B. It also meets API GL-4 gear oil requirements and can be used in applications requiring API CF-4 or API SF engine oil performance levels. Physical characteristics include a kinematic viscosity of approximately 14.5 mm²/s at 100°C, a viscosity index of approximately 135, a density of approximately 890 kg/m³ at 15°C, a flash point of approximately 226°C and a pour point of approximately –27°C.
