(1) First Choice: Cat Cold Weather TDTO SAE 0W-20. Second Choice: Oils of full synthetic basestock that do not have viscosity index improvers and do meet the performance requirements of the Cat TO-4 specification for the SAE 30 viscosity grade. Typical lubricant viscosity grades are SAE 0W-20, SAE 0W-30, and SAE 5W-30. Third Choice: Oils that contain a TO-4 additive package and a lubricant viscosity grade of SAE 0W-20, SAE 0W-30, or SAE 5W-30.
(2) Cat TDTO-TMS (Transmission Multi-Season) (synthetic blend that exceeds the Cat TO-4M multigrade specification requirements).
