Oil Drain Intervals for Pre-2007 Series 60, Series 55, MBE 900, and MBE 4000 Engines
The oil drain intervals for Series 60, Series 55, MBE 900, and MBE 4000 pre-2007 engines, listed in the table below, are based on On-Highway engines operating with ULSD fuel (below 15 ppm) with Detroit Fluids Specification DFS 93K222, DFS 93K218 and DFS 93K214, API licensed CK-4/CJ-4/CI-4 PLUS oil. These intervals should be considered as maximum and should not be exceeded. If operating in regions where ULSD is not available then these intervals will apply as long as the proper oil quality per table "API Symbol: Four-Cycle Engine Oils" is utilized.
