In the August 15, 2016 issue of the OEM/Lube News, we stated that inline with the forthcoming API CK-4 diesel engine category, Cummins has established two new standards, Cummins Engineering Standard [CES] 20086, which is an updated version of CJ-4 (CES 20081), and is recommended for all engines using Ultra-Low Sulfur Diesel (ULSD) and CES 20087 for diesel engines designed for a lower viscosity oil and only intended for use in certain newer on-highway diesel engines .
Cummins has updated its CES 20086 list of API CK-4 registered oils, now totaling 136 oils compared to the list we showed four months ago of 83 oils. Its CES 20087 list of API FA-4 registered oils is now at 15 oils, up from 11 oils when we last published the list four months ago.
CES 20086 oils can be used as the normal fill and top-off on older engines, and will have a higher oxidation capacity, to handle the increased heat load in today’s hotter-running engines. It will be the oil of choice for most Cummins engines.
CES 20087 oils are for diesel engines designed for a lower viscosity oil and only intended for use in certain newer on-highway diesel engines.
