The ILSAC Specifications (International Standardization and Approval Commitee) uses together with another American Institute and the JAMA (Japan Automobile Manufacturers Association) the API Classifications for an individual ILSAC Standard: T
MIL-Specifications (Military Standard in USA)—A United States defense standard, often called a military standard, “MIL-STD“, “MIL-SPEC“, or (informally) “MilSpecs“, is used to help achieve standardization objectives by the United States Department of Defense.
ILSAC Specifications with JAMA MIL — From API
| GF-7 | ILSAC GF-7 offers protection against Low-Speed Pre-Ignition (LSPI), safeguards timing chain wear, provides enhanced high-temperature deposit control for pistons and turbochargers, enforces stricter sludge and varnish management, improves fuel economy, strengthens emission control system protection, and ensures compatibility with engines running on E85 ethanol fuel. |
| GF-6 | Provide protection against low-speed pre-ignition (LSPI), timing chain wear protection, improved high temperature deposit protection for pistons and turbochargers, more stringent sludge and varnish control, improved fuel economy, enhanced emission control system protection and protection of engines operating on ethanol-containing fuels up to E85. |
| GF-6A | Current: introduced in May 2020 for oil viscosities a slow as 0W-20. |
| GF-6B | Current: introduced in May 2020 for engines requiring 0W-16 oils. |
| GF-5 | Current: introduced in October 2010, designed to provide improved high temperature deposit protection for pistons and turbochargers, more stringent sludge control, improved fuel economy, enhanced emission control system compatibility, seal compatibility, and protection of engines operating on ethanol-containing fuels up to E85. (obsolete on May 1, 2021) |
| GF-4 | Obsolete: use GF-6A where GF-4 is recommended. |
| GF-3 | For 1996 and older engines. |
| GF-2 | Obsolete: 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. |
| GF-1 | Obsolete: not suitable for use in most gasoline-powered automotive engines built after 1988. May not provide adequate protection against build-up of engine sludge. |
