API
In general, the API value of an oil consists of 2 parts:
Example: API SJ/CF
S = stands for "Service Oils" - use in petrol engines.
J = provides information on the quality of the oil when used in petrol engines.
C = for "Commercial Oils"- use in diesel engines.
F = provides information on the quality of the oil when used in diesel engines.
The following qualities haven been classified according to API up to the present:
- SA: no longer valid: Regular motor oils possibly with Stockpunktverbesserer and / or foam inhibitors.
- SB: no longer valid: Wenigbeanspruchte petrol engine oils with additives to aging, corrosion and wear. Since 1930. - SC: No longer valid: Otto engine oils which are exposed to average operating conditions. With active ingredients to corking, cold sludge, aging, corrosion and wear. From 1964 - 1971st.
- SD: no longer valid: Otto engine oils with higher operating conditions than API-SC. Of 1968 - 1971st.
- SE: no longer valid: Motor Oils for very high standards and highly contaminated petrol engines (stop-and-go traffic). From 1971 - 1979.
- SF: no longer valid: Motor Oils for very high standards and highly contaminated petrol engines (Stop-and-go traffic). From 1980 - 1987. Exceeds API-SE in oxidation stability, wear protection and sludge carrying capacity.
- SG: obsolete: Motor Oils with the highest requirements, special tests for oxidation stability and sludge formation. From 1987 - 1993.
- SH: date: Meets largely API SG, concerning additional requirements HTHS, evaporation, filtration, foam behavior and flash point. From 1993 - 1996.
- SJ: current: succeeded to SPI-SH. Stricter requirements for evaporation loss.
- SL: news: Once again, more stringent requirements regarding oil consumption, engine cleanliness and aging behavior. For extended oil-change intervals. Introduced in 2001.
- M: current: Once again tightened requirements for oxidation stability, engine cleanliness, wear protection, aging behavior and performance at low temperature.
Class: Status: Application / Requirements
- CA: no longer valid: For easy claimed gasoline and diesel engines operated on low sulfur fuels. Suitable for motors up to the 50.
- CB: No longer valid: for mild to mittelbelastete gasoline and diesel self-priming, which are operated with sulfur-rich fuels. Engines 1949. Provide protection against high temperature deposits and bearing corrosion.
- CC: No longer valid: For gasoline and diesel engines, the moderate to severe operating conditions are exposed. Provide protection against cold sludge, corrosion and high temperature deposits. 1961.
- CD: obsolete: motor oils for heavily loaded diesel engines with and without charge. Introduced in 1955.
- Outdated CD II:: Meets API CD met the additional requirements of two-stroke diesel engines Increased protection against wear and deposits. Introduced 1987.
- CE: obsolete: motor oils for heavily loaded and high-speed diesel engines with and without charge, which are often highly variable loads. Increased protection against Oil-thickening and wear, improved piston cleanliness. Instead of API CC and CD can be used. Introduced in 1987.
- CF: News: Replaced from 1994 API CD. For highly supercharged diesel engines. High ash. Suitable for diesel fuels with sulfur content> 0.5%.
- CF-2: current: Only for two-stroke diesel engines. Replaced from 1994 API-CD II.
- CF-4: obsolete: For fast and supercharged four-stroke diesel engines. Covers the requirements of API CD, CE, supplemented by requirements for oil consumption and piston cleanliness. Introduced in 1990.
- CG-4: current: For heavy-duty truck engines. Take into account EPA emission boundaries after 1994. Better detergent properties and better foaming properties as API CF-4. Can instead of API CD, CE and CF 4 are used. Introduced in 1995.
- CH-4: current: designed for high-revving four-stroke engines, the stringent new exhaust regulation. Comparable with ACEA E5, lower Ash content. For sulfur content to 0.5%. Can instead of API CD, CE, CF-4, CG-4 and can be used. Introduced in 1998.
- CI-4: current: For high-revving four-stroke engines, the emissions laws in the future only can fulfill using exhaust gas recirculation. For sulfur content to 0.5%. Can instead of API CD, CE, CF-4, CG-4 and CH 4 can be used. Introduced in 2002.
- CJ-4: current: For high-revving four-stroke engines to meet the required starting in 2007, "highway emissions standards. Especially for vehicles with particulate filter systems and sulfur contents up to 0.0015%. Introduced in 2006.
