API CJ-4 oils exceed the performance criteria of API CI-4 with CI-4 PLUS, CI-4, CH-4, CG-4 and CF-4 and can effectively lubricate engines calling for those API Service Categories. When using CJ-4 oil with higher than 15 ppm sulfur fuel, consult the engine manufacturer for service interval. CI-4 : Current: Introduced in 2002.

Oils meeting API SL requirements have been tested according to the American Chemistry Council (ACC) Product Approval Code of Practice and may utilize the API Base Oil Interchange and Viscosity Grade Engine Testing Guidelines.

Service classifications are determined by the American Petroleum Institute (API), while oil viscosity grades are determined by the Society of Automotive Engineers (SAE). These two organizations have set industry standards for motor oils for more than 80 years.
The API “S” series describes oil standards primarily for gasoline engines while the API “C” series describes oil standards for diesel engine service. A description of the API service symbol and category mark can be found in the Engine Oil Guide published by the API [1875] .
oils are neither interchangeable nor backward compatible with API CK-4, CJ-4, CI-4 with CI-4 PLUS, CI-4 and CH-4 oils. Refer to engine manufacturer recommendations to determine if FA-4 oils are suitable for use. FA-4 oils are not recommended for use with fuels having greater than 15 ppm sulfur. Obsolete
4 Δεκ 2019 · Oil quality grades for diesel engines: • CC – for light diesel engines; prevents the accumulation of dirt generated during high-temperature operation. • CD – for heavily operated four-stroke diesel engines; with additives to prevent abrasion and accumulation of deposits. • CD-II – for two-stroke diesel engines.
