Mobil Agri Extra 10W-40
Mobil Agri Extra 10W-40 is a high-performance synthetic blend Super Tractor Oil Universal (STOU) lubricant developed to meet the demanding lubrication requirements of modern agricultural equipment. Formulated using high-quality base oils combined with an advanced additive system, Mobil Agri Extra 10W-40 delivers reliable lubrication performance across multiple equipment components including diesel and gasoline engines, transmissions, hydraulic systems, final drives and oil-immersed brakes. The multi-functional formulation allows a single lubricant to service multiple systems in agricultural machinery, helping simplify maintenance and reduce the risk of lubricant misapplication.
One of the key advantages of Mobil Agri Extra 10W-40 is its excellent thermal and oxidation stability. Agricultural machinery often operates under heavy loads and high temperatures, which can lead to lubricant degradation and deposit formation. Mobil Agri Extra 10W-40 is designed to resist oxidation and maintain lubricant performance, helping reduce sludge formation and high-temperature deposits while supporting long equipment service life.
Mobil Agri Extra 10W-40 also provides strong protection against wear across multiple equipment components. The advanced additive system helps protect engine components, hydraulic systems and powertrain parts from wear under demanding operating conditions. This protection is particularly beneficial for hydraulic components and transmission systems that experience continuous mechanical stress during agricultural operations.
Another important benefit of Mobil Agri Extra 10W-40 is its effective detergency and dispersancy properties. These characteristics help keep engines clean by preventing sludge and deposit formation while maintaining efficient engine operation. The lubricant also helps control oil consumption and reduce the risk of bore polishing and engine scuffing during heavy-duty agricultural service.
Mobil Agri Extra 10W-40 also provides excellent frictional and load-carrying performance in agricultural transmissions and wet brake systems. The lubricant helps deliver smooth powertrain operation while preventing brake chatter in oil-immersed brake systems commonly found in agricultural equipment. In addition, the formulation offers excellent low-temperature pumpability, supporting easier engine start-up and responsive hydraulic system performance in colder operating conditions.
Mobil Agri Extra 10W-40 is recommended for a wide range of agricultural machinery including mixed diesel and gasoline-powered farm vehicles and equipment, as well as transmissions and power systems requiring multi-functional lubricants. The lubricant meets or exceeds numerous industry and equipment manufacturer requirements including API CE, API CF-4, API CG-4 and API GL-4 as well as specifications from major agricultural equipment manufacturers.
Physical characteristics include a kinematic viscosity of approximately 93 mm²/s at 40°C and 13.5 mm²/s at 100°C, with a viscosity index of around 146. Mobil Agri Extra 10W-40 has a density of approximately 0.86 g/ml at 15°C, a flash point of approximately 229°C and a pour point of approximately −42°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.
