General Information

Because of government regulations regarding the certification of engine exhaust emissions, the lubricant recommendations must be followed.

Engine Manufacturers Association (EMA) Oils

The "Engine Manufacturers Association Recommended Guideline on Diesel Engine Oil" is recognized by AVSpare. For detailed information about this guideline, see the latest edition of EMA publication, "EMA LRG-1".

API Oils

The Engine Oil Licensing and Certification System by the American Petroleum Institute (API) is recognized by AVSpare. For detailed information about this system, see the latest edition of the "API publication No. 1509". Engine oils that bear the API symbol are authorized by API.

API Classifications 
Current  Obsolete 
CI-4, CH-4, CG-4 (1)  CE 
CF (2)  CC, CD 
CF-2(3)  CD-2(3) 
(1) API CF-4 oils are no longer recommended for AVSpare diesel engines.
(2) API CF oils are not recommended for AVSpare diesel engines.
(3) API CF-2 and CD-2 oils are classifications for two-cycle diesel engines. AVSpare does not sell engines that utilize the CD-2 and the API CF-2 oils.

Grease

The classifications of grease are based on the "ASTM D217" worked penetration characteristics. These characteristics for grease are given a defined consistency number.

Terminology

Certain abbreviations follow the nomenclature of "SAE J754". Some classifications follow "SAE J183" abbreviations, and some classifications follow the "EMA Recommended Guideline on Diesel Engine Oil". In addition to AVSpare definitions, there are other definitions that will be of assistance in purchasing lubricants. Recommended oil viscosities can be found in this publication, "Engine Oil" topic (Maintenance Section).
