In the August 15, 2016 issue of the OEM/Lube News, we stated that inline with the forthcoming API CK-4 diesel engine category, the oils used in Cummins engines must meet 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 20081.
CES 20086 is going to be available in 10W-30 and 15W-40 formulations, as well as other traditional viscosity grades. It 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.
"The CES 20087 registered oils list and additional CES 20086 registered oils should be introduced and added in the next couple weeks as they come in", Ryan Denton, Ph.D.,Lubricant Technical Specialist, Corporate Chemical Technology, Cummins Technical Center, Columbus, IN, told OEM/Lube News.
