CASTROL AXLE FD-1 80W-140 (SEMI-SYNTHETIC)
Castrol Axle FD-1 is semi synthetic, multi grade final drive fluid designed to extend drain intervals up to 6000 hours* in off road final drives where FD-1 spec. fluids are suitable for use. Additionally, Castrol Axle FD-1 provides excellent wear protection and outstanding oxidation resistance extending component life.
Oxidation Resistance
Castrol Axle FD-1’s outstanding resistance to oxidation improves fluid life while resisting the formation of sludge and deposits. In the ASTM D2272 oxidation test, Castrol Axle FD-1 demonstrated up to 56% oxidation resistance versus conventional monograde fluids providing greater assurance during extended drain intervals. Additionally, Castrol Axle FD-1’s synthetic base stock withstands a wide range of operating temperatures.
Wear Protection
The excellent wear protection offered by Castrol Trans-C and Castrol Axle FD-1 Fluids is further demonstrated in the ASTM D4998 FZG test which measures gear teeth wear. Castrol Axle FD-1 improved wear protection when compared to mineral TO-4 50 fluids, providing enhanced protection to final drives.
