45 | ASP June 2016 Technical Category Status Service CD Obsolete CAUTION: Not suitable for use in most diesel-powered automotive engines built after 1994. CC Obsolete CAUTION: Not suitable for use in most diesel-powered engines built after 1990. CB Obsolete CAUTION: Not suitable for use in most diesel-powered engines built after 1961. CA Obsolete CAUTION: Not suitable for use in most diesel-powered engines built after 1959. Gasoline engines Category Status Service SN Current Introduced in October 2010, designed to provide improved high tempera- ture deposit protection for pistons, more stringent sludge control, and seal compatibility. API SN with Resource Conserving matches ILSAC GF-5 by combining API SN performance with improved fuel economy, turbocharger protection, emission control system compatibility, and protection of engines operating on ethanol-containing fuels up to E85. SM Current For 2010 and older automotive engines. SL Current For 2004 and older automotive engines. SJ Current For 2001 and older automotive engines. SH Obsolete OBSOLETE: For 1996 and older automotive engines. SG Obsolete CAUTION: Not suitable for use in most gasoline-powered automotive engines built after 1993. May not provide adequate protection against build-up of engine sludge, oxidation, or wear. SF Obsolete CAUTION: Not suitable for use in most gasoline-powered automotive engines built after 1988. May not provide adequate protection against build-up of engine sludge. SE Obsolete CAUTION: Not suitable for use in most gasoline-powered automotive engines built after 1979. SD Obsolete CAUTION: Not suitable for use in most gasoline-powered automotive engines built after 1971. Use in more modern engines may cause unsatisfac- tory performance or equipment harm. SC Obsolete CAUTION: Not suitable for use in most gasoline-powered automotive engines built after 1967. Use in more modern engines may cause unsatisfac- tory performance or equipment harm. SB Obsolete CAUTION: Not suitable for use in most gasoline-powered automotive engines built after 1951. Use in more modern engines may cause unsatisfac- tory performance or equipment harm. SA Obsolete CAUTION: Contains no additives. Not suitable for use in most gasoline- powered automotive engines built after 1930. Use in modern engines may cause unsatisfactory performance or equipment harm. For automotive gasoline engines, the latest ILSAC standard or API service category includes the performance properties of each earlier category and can be used to service older engines where earlier category oils were recommended. Follow the vehicle manufacturer's recommen- dations on oil performance levels.
