MIL-PRF-2104L, PERFORMANCE SPECIFICATION: LUBRICATING OIL, INTERNAL COMBUSTION ENGINE, COMBAT/TACTICAL SERVICE (25-APR-2017) [USE MIL-PRF-002104L IN LIEU OF MIL-PRF-2104K]., This specification is approved for interim use by all Departments and Agencies of the Department of Defense. Other activities in the Department of Defense may use this interim revision or may continue using MIL-PRF-2104K. This performance specification covers lubricating oils suitable for lubrication of reciprocating compression-ignition internal combustion engines and for power transmission fluid applications in combat/tactical service equipment (see 6.1). Grade SCPL is intended to be an all-season lubricant providing extended drain intervals and reduced fuel consumption (see 6.1). The lubricating oils covered by this specification are military standard lubricants. The combination of engine and heavy-duty transmission requirements in this specification are not required of typical commercial diesel engine oils. They are intended for use in combat and tactical equipment including the crankcase lubrication of reciprocating compression-ignition engines, heavy-duty automatic and powershift transmissions, hydraulic systems, and non-hypoid gear units of engineer/construction and material handling equipment. Although lubricants meeting the requirements of this specification have been formulated to meet a wide range of lubricating functions, it is brought to the attention of the equipment developer the requirement to ensure that equipment, whether military unique or commercially-off-the-shelf (COTS), are compatible with military standard lubricants (see AR 70-12 and MIL-HDBK-838 for additional guidance). Monograde lubricating oils (e.g., OE/HDO-40) covered by this specification meets, at a minimum, service category API CH-4. Multigrade lubricating oil (e.g., OE/HDO-15/40 and SCPL) covered by this specification meet, at a minimum, service category API CI-4. SCPL should not be used in legacy Detroit Diesel Corporation (DDC) high output 2- cycle heavy-duty diesel engines if ambient temperatures exceed 90°F. SCPL is intended to be a direct replacement for previous applications requiring a 10W and the arctic engine oil (i.e., MILPRF-46167, OEA-30). Although lubricants qualified to this specification have been tested in accordance with selected Allison Transmission Inc. and Caterpillar Inc. transmission lubricant requirements, without further testing and certification, they cannot be recognized as compliant with either company’s lubricant specifications.
