API Diesel Engine Specification |
| API SPEC / YEAR | APPLICATION |
| CH.4 / 2001 | Very heavy duty diesel engines where tighter
emission controls for diesel engines turbo charged with long drain,
low emission, capabilities are essential. |
| CG.4 / 1997 | Very heavy duty diesel engines where the lubricant
must meet performance with low sulphur diesels, soot related wear
protection, and protection against oxidation. |
| CF.4 / 1990 | Heavy duty diesel engines used for high speed
application. Better lubricant consumption and deposits control.
|
| CE / 1988 | Heavy duty diesel engines which are turbo-charged
and built after 1983 operating in both high and low speed load. |
CD / 1955 |
Heavy duty diesel engines which are super-charged and using fuels of miscellaneous quality. |
| CC/ 1952 | Medium duty diesel engines with slight application
to corrosion and wear properties and protection against sludging. |
| CB / 1949 | Moderate duty diesel engines using ordinary
fuel with high sulphur content, protects against deposits at high
temperatures. |
| CA / 1939 | Light duty diesel engines normally aspirated and protection against corrosion of bearing by deposits at high temperatures. |
