The oils will now be designated as Diesel Engine Oils with the API performance rating - DEO CD and DEO CF-4.
The DEO CD oil is the same oil formulation as the former DEO, but the multi-viscosity oils have been discontinued. The DEO CF-4 oil is a new oil formulation which meets the API CF-4 performance requirements. This API CF-4 oil is now the recommended oil for all Caterpillar Engines except the 3600 Family of Engines. The DEO CD oil is still recommended for the 3600 Family of Engines.
The part numbers for all the mono-grade DEO CD oils remain the same for all container sizes. All EO oil part numbers and DEO multi-grade oil part numbers have been canceled. The DEO CF-4 oils have new part numbers for all container sizes. Consult your Caterpillar Dealer for DEO CF-4 oil part numbers.
