的 API SQ lubricant standard—March 31, 2025, revolutionize motor oil performance requirements. Building upon API SP, this standard addresses modern Turbocharged Gasoline Direct Injection (TGDI engine oil) demands with stricter low-speed pre-ignition oil specifications and enhanced fuel economy lubricant properties.
Why SQ? Meeting TGDI & LSPI Challenges
Turbocharged GDI engines suffer from LSPI protection failures, leading to knocking and piston damage. API SQ mandates new tests to prevent low-speed pre-ignition and impose an x-sequence chain wear test to safeguard timing chains. These upgrades ensure oils can withstand higher temperatures and pressures, reducing costly repairs.
Aligning with ILSAC GF-7 & GPF Protection
API SQ matches ILSAC GF-7 in controlling deposits and improving GPF protection. By capping sulfate ash at 0.9%, SQ oils help safeguard gasoline particulate filters—essential for compliance with upcoming EPA emissions standards for 2026 model vehicles.
Core SQ Requirements Breakdown
1.LSPI Resistance: Prevent engine knock in TGDI engines
2.Chain Wear Test (x-sequence): Extend timing-chain life
3.High-Temp Oxidation Stability: Maintain viscosity under stress
4.Deposit Control: Reduce sludge and varnish
5.Low-Temp Flow: Ensure quick lubrication at startup
6.Sulfated Ash Limit (≤0.9%): Protect GPFs
7.Fuel Economy Performance: Contribute to EPA targets
