This specification covers engine oils for light-duty and heavy-duty internal combustion engines used under a variety of operating conditions in automobiles, trucks, vans, buses, and off-highway farm, industrial, and construction equipment. Automotive engine oils are classified in three general arrangements: S, C, and Energy Conserving. These arrangements are further divided into categories with performance measured as follows: SH, SJ, SL, SM, CF-4, CF, CF-2, CG-4, CH-4, CI-4, CJ-4, Energy Conserving associated with SJ, and Energy Conserving associated with SL. Different bench and chemical tests shall be performed to help evaluate some aspects of engine oil performance.
