Understanding ILSAC GF-7: The Next-Gen Engine Oil Standard
The ILSAC GF-7 specification, launching March 31, 2025, marks a critical leap in passenger car motor oil (PCMO) technology. Designed to meet stricter fuel economy and emission regulations, this new oil specification addresses key challenges like low-speed pre-ignition (LSPI), piston deposits, and timing chain wear—critical for modern turbocharged GDI engines.
Key Upgrades in GF-7 Oil vs. GF-6 Oil
1.Enhanced Fuel Efficiency
Tighter Sequence VIE/IIIH limits reduce friction in 0W-20/5W-30 ILSAC grades.
New Oil Gelation Test (ASTM D6795) prevents oil gelling during vehicle storage.
2.Stronger Engine Protection
Sequence IX LSPI testing for aged oils ensures consistent anti-knock performance.
0.9% max sulfated ash protects gasoline particulate filters (GPFs).
3.Cold-Weather Performance
MRV viscosity capped at 40,000 cP for reliable cold starts.
