The International Lubricant Standardization and Approval Committee (ILSAC) also has standards for motor oil. Their latest standard, GF-4 was approved in 2004. A key test is the Sequence IIIG, which involves running a 3.8 L, GM 3.8 L V-6 at 125 horsepower (93 kW), 3600 rpm, and 150 °C (300 °F) oil temperature for 100 hours. These are much more severe conditions than any API-specified oil was designed for: cars which typically push their oil temperature consistently above 100°C (212°F) are most turbo-charged engines, along with most engines of European or Japanese origin, particularly small capacity, high power output.
API SM - American Petroluem Institute (API) Service/Petrol or Spark Ignition Engine(S) For all automotive engines currently in use. Introduced in 2004, SM oils are designed to provide improved oxidation resistance, better wear protection, and better low-temperature performance over the life of the oil. Some SM oils may also meet the latest ILSAC specification and/or qualify as Energy Conserving

API - American Petroleum Institue
ILSAC - International Lubricant Standardization and Approval Committee
SM - Introduce in 2004, provide improved oxidation resistance, better wear protection, and better low-temperature performance over the life of the oil.
SG - For 1993 and older engines.
CF - Introduced in 1994. For off-road, indirect-injected and other diesel engines including those using fuel with over 0.5% weight Sulphur. Can be used in place of CD oils.
CD - Introduced in 1955. For certain naturally aspirated and turbocharged engines.
GF-4 Their latest standard, GF-4 was approved in 2004, and applies to SAE 0W-20, 5W-20, 0W-30, 5W-30, and 10W-30 viscosity grade oils
