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 Caterpillar 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).
