General

This SAE Standard describes lubricating oils meeting the physical, chemical and performance requirements of American Petroleum Institute (API) performance categories CF and CF-2, CI-4, supplement CI-4 PLUS, and SAE J300. These oils are suitable for the lubrication of wheeled vehicles with compression-ignition (diesel) engines. This document supersedes the military's Commercial Item Description (CID) A-A-52306.

Intended Use

The lubricating oils described by this document are only intended for use in the engines of Tactical Wheeled and administrative vehicles equipped with diesel engine systems. The multigrade oils are suitable for use in 4-cycle diesel engines while the monograde oils are preferred for use in high output 2-cycle diesel engines. These lubricating oils are not a replacement for SAE J2359 (Lubricating Oil, Internal Combustion Engine, Military Combat/Tactical Service), nor is it intended for use in transmissions or hydraulic systems.

Rationale

The conversion of the commercial item descriptions (CID) AA-52306 to SAE J2363 in November 1998 was done as an effort to align military needs with commercial manufacturers requirements and suppliers products. It is our belief that the API Engine Oil Licensing and Certification System (EOLCS), the American Chemistry Council (ACC) Petroleum Additives Product Approval Code of Practice provide a robust framework of requirements and oversight to allow the Department of Defense to purchase these products directly, with the understanding that only products with a formal API license and meeting the most current Heavy Duty Diesel Engine Oil requirements will be procured.
