Classification of Energy Conserving Engine Oil and Resource Conserving Engine Oil for Passenger Cars, Vans, Sport Utility Vehicles, and Light-Duty Trucks
This SAE Recommended Practice was developed cooperatively by SAE, ASTM, and API to define and identify Energy Conserving or Resource Conserving engine oils for passenger cars, vans, sport utility vehicles, and light-duty (3856 kg [8500 lb] GVW or less) trucks.
Rationale: The scope of the revision to this Recommended Practice is to include the API SM Energy Conserving Category (ILSAC GF-4 related), API SN Resource Conserving Category (ILSAC GF-5 related) and also the use of the ASTM Sequence VIBSJ test for API SJ (ILSAC GF-2). The revisions bring SAE J1423 up to date on current classification of Energy Conserving and Resource Conserving oils for passenger cars, vans, sport utility vehicles, and light duty trucks.
