ILSAC GF-3 was first introduced in 2001 for use in gasoline engines in passenger cars.
API has discontinued licensing engine oils against ILSAC GF-3 and it became an obsolete specification in April 2004.
API recommends that oils meeting the latest ILSAC standard are used in applications where ILSAC GF-3 is specified. Due to newer ILSAC standards (ILSAC GF-5, and GF-4) being suitable for use in applications specifying ILSAC GF-3 it is possible to find oils available today that claim to meet the requirements of ILSAC GF-3.
Oils meeting ILSAC GF-3 are typically low HTHS (≤ 3.5cP) SAE 10W-30, 5W-30, 0W-30, 5W-20 or 0W-20 based on API Group II, Group III or Group IV base oils and coupled with API SL and an energy conserving claim.
