SAE J2359_201302

This SAE Standard covers engine military oils suitable for lubrication of reciprocating internal combustion engines of both spark-ignition and compression-ignition types, and for power transmission fluid applications in combat/tactical service equipment (see 7.1). This document is equivalent to MIL-PRF-2104G when all requirements are met. SAE J2359 was originally issued November 1998 as a means to leverage non-government standard organizations such as SAE to better align military needs with commercial manufacturers and suppliers. Unfortunately, because of the relatively rapid changes in the API heavy-duty diesel engine oil service categories, mainly driven by emission requirements, the commercial and military requirements have become increasingly out of sync. This inconsistency has led to very little interest among industry and support of these documents. Furthermore, because of military uniqueness of the requirements, the administration of these documents is most efficiently handled within the Department of Defense, under current procedures for military performance requirements/specifications.
