Customer Benefits

• Minimizes application problems
  Unique multi-application additive package enables use in engines, transmissions, final drives and hydraulic systems, avoiding costly equipment failure due to misapplication.
• Reduced maintenance costs
  Outstanding oxidation and nitration resistance minimizes acid number increase, providing protection against bearing corrosion.
• Extended oil change periods
  Very high oxidation stability protects against the formation of gums and varnishes, reduces oil thickening and increases oil life.
• Maintains power output
  Detergent/dispersant additive system maintains power output by providing deposit control under the high temperature conditions encountered in both naturally aspirated and turbocharged diesel vehicles. Multiviscosity characteristics ensure rapid oil circulation on start-up, preventing wear which contributes to power loss.
• Smooth and quiet operation
  Special friction modifier component allows smooth action of the wet brakes and power take-off clutches, minimizing chatter, stick slip and squawk.

Applications

• Where tractor manufacturers specify the use of a STOU type product.
• Mixed fleets of agricultural tractors and associated equipment.
• Enclosed oil immersed (wet) brakes.
• Power take off (PTO) clutches.

Service Considerations

Super Tractor SAE 15W-40 is a multifunctional fluid of the super tractor oil universal (STOU) type that is intended for use in both the engines and transmission compartments of agricultural tractors and related equipment, including those fitted with oil-immersed brakes.

For current and recent tractors, manufacturers separately specify the engine oil and transmission fluid requirements. Thus in each case it is necessary to determine that Super Tractor SAE 15W-40 meets both sets of requirements. Historically some tractor makers issued a single STOU specification that covered both engines and transmission, but thi practice has been discontinued for many years.

The diversity of tractor transmission fluid specifications is such that there are some mutual exclusivities, and it is not possible for one fluid to completely meet all specifications. Also, some specifications are not publicly available. Thus in some cases, Super Tractor SAE 15W-40 is offered on a suitable-for-use basis, supported by a comprehensive combination of bench and equipment testing.

Although Super Tractor SAE 15W-40 does meet API GL-4, this is a secondary target and it is nevertheless not designed for nor intended for use in any on-highway drive axles of the hypoid type.
