RAL Tractor Oil Universal (STOU)
RAL Tractor Oil Universal series are multifunctional tractor lubricants designed for use in a wide variety of modern farm equipment. These oils are blended from specially selected base stocks and advanced additive package to provide reliable performance in wide range of farming applications. These high performance STOU oils are suitable for use in diesel/gasoline engines, conventional gear drives, power shift transmissions, hydrostatic transmissions, hydraulics, final drives, power steering systems and oil immersed brakes operating in agricultural services. These oils are available in SAE 10W-30, 10W-40, 15W30, 15W-40 and 20W-50 grades to enable the users to select an appropriate viscosity grade as recommended by farm equipment manufacturers for optimum performance
Application
- Suitable for most of the diesel/gasoline engines and transmission/hydraulic systems of tractors and other farm equipment
- Also suitable for other applications of farm equipment including oil immersed brakes, power shift transmissions, hydrostatic transmissions, power steering systems and conventional gear drives
Benefits
- Multifunctional capability of these oils makes them suitable for most lubricant applications in farm equipment and reduces inventory and chances of misapplication.
- Good thermo-oxidative stability and effective detergency/dispersancy controls sludge build-up and deposits leading to cleaner engines.
- Protects gears, transmissions and bearings against wear, scuffing and pitting
- Ensures smooth (jerk free) hydraulic operation.
- Excellent anticorrosion property protects all working components.
- Good low temperature property ensures less wear and improved hydraulic response at cold start-up
