Engine Oils Background & Properties castrol.com/GPS 800 255 4417 May 2025 GPS Industry Specifications Other OEM Specifications Oen, API performance categories do not meet the additional requirements sought by every engine manufacturer. For this reason and others, OEMs may elect to issue their own engine oil classifications. ese classifications typically apply to specified engine models and/or operating conditions. Over the years, some of these classifications have included the following: Cummins CES 20092 Unlike the diesel engine oil specs listed below, this Cummins specification is specifically for natural gas engine oils. Cummins CES 20086 is Cummins specification is similar to CK-4, but with tighter test limits. Cummins 20087 is specification for FA-4 is similar to CK-4, but with different limits for viscosity. Detroit Diesel Power Guard 93K222 is specification for CK-4 tends to have the CJ-4 test criteria as 93K218 (below), but with some tighter limits. Detroit Diesel Power Guard 93K223 is specification for FA-4 tends to have the CJ-4 test criteria, but with some tighter limits. Detroit Diesel Power Guard 93K218 is specification is intended for all four-stroke cycle series engines with an aertreatment system, EPA 07 and older (including legacy engines), operating on ULSD fuel. ese oils are similar to API CJ-4. Detroit Diesel Power Guard 93K214 is specification is for engine oils used in the Detroit Diesel engines model year 2002 and newer Series 50 and 60 and Mercedes Benz MBE 400 and MBE 900 engines. is specification was needed to address the rapidly changing requirements for emission-controlled engines. API CI-4 Plus tests formed the core of the category with additional tests to assure lubricant performance for newer emission-controlled engines, particularly those using cooled EGR. Another key purpose behind this specification is to extend drain intervals up to 50 percent in some engines. Mack VDS 4.5 is specification for CK-4 tends to have the CJ-4 test criteria, but with some tighter limits. A12 ecastrof
