Mobil Agri Super 15W-40
Mobil Agri Super 15W-40 is a high-performance multi-functional Super Tractor Oil Universal (STOU) lubricant developed to meet the diverse lubrication requirements of modern agricultural machinery. Formulated using high-quality base oils and an advanced additive system, Mobil Agri Super 15W-40 delivers dependable lubrication performance for diesel and gasoline engines, transmissions, hydraulic systems, final drives and oil-immersed brakes operating in agricultural service. The versatile formulation allows a single lubricant to be used across multiple equipment systems, helping simplify maintenance procedures and reduce the risk of lubricant misapplication in farming operations.
One of the key advantages of Mobil Agri Super 15W-40 is its strong thermal and oxidation stability. Agricultural equipment frequently operates under heavy loads and elevated temperatures, which can accelerate lubricant degradation and deposit formation. Mobil Agri Super 15W-40 is formulated to resist oxidation and maintain lubricant stability, helping minimise sludge formation and high-temperature deposits while supporting reliable equipment operation over extended service periods.
Mobil Agri Super 15W-40 also provides excellent wear protection for critical components across engines, transmissions and hydraulic systems. The advanced additive technology helps protect metal surfaces under demanding operating conditions, reducing component wear and extending the service life of agricultural machinery. This protection is particularly beneficial for hydraulic components and drivetrain systems that operate under constant mechanical stress during agricultural work.
Another important benefit of Mobil Agri Super 15W-40 is its effective detergency and dispersancy performance. These properties help maintain engine cleanliness by preventing the formation of sludge and deposits within the engine. Cleaner engine components support efficient combustion, consistent lubrication performance and extended engine life in demanding agricultural service environments.
Mobil Agri Super 15W-40 also provides excellent frictional and load-carrying characteristics in agricultural transmissions and wet brake systems. The lubricant helps deliver smooth power transfer while preventing brake chatter in oil-immersed brake systems commonly found in farm equipment. In addition, the formulation offers reliable low-temperature pumpability, enabling easier engine start-up and responsive hydraulic system performance in colder operating conditions.
Mobil Agri Super 15W-40 is recommended for use in mixed diesel and gasoline-powered farm vehicles and equipment, as well as transmissions and power systems requiring multifunctional lubricants. The product meets a wide range of industry and equipment manufacturer requirements including API CE, API CF, API CF-4 and API GL-4, as well as approvals from major agricultural equipment manufacturers such as Massey Ferguson and John Deere.
Physical characteristics include a kinematic viscosity of approximately 90 mm²/s at 40°C and 12.9 mm²/s at 100°C, with a viscosity index of around 141. Mobil Agri Super 15W-40 has a density of approximately 0.87 g/ml at 15°C, a flash point of approximately 235°C and a pour point of approximately −40°C. The oil also provides a Total Base Number of approximately 12 mgKOH/g and sulfated ash content of approximately 2%, supporting reliable lubrication performance and protection for agricultural equipment operating under demanding conditions.
