ZT73191 enables extended drain intervals exceeding 20,000 km while maintaining critical aftertreatment compatibility, providing comprehensive protection for engines operating with 300+ bar fuel pressures, exhaust gas recirculation rates exceeding 25%, and turbocharger temperatures surpassing 1050°C.
LSPI Elimination: Halogen-free combustion modifiers reduce pre-ignition events by >95% in Ford EcoBoost sequence testing.
Chain System Preservation: Ultra-adherent anti-wear films limit timing chain elongation to <0.08% after 300h engine testing.
Turbo Protection: High-temperature calcium sulfonates prevent compressor fouling with <10mg deposit weight in Peugeot TUR111 test.
Fuel Economy Enhancement: Organic molybdenum complexes deliver 2.7-3.1% improvement in Sequence VIE testing.
Aftertreatment Safeguarding: Ultra-low sulfated ash (0.7-0.9%) and phosphorus (<800ppm) preserve GPF filtration efficiency.
Oxidative Stability: Hybrid antioxidant system maintains TBN >50% after 180h TEOST 33C testing.
Turbocharged GDI Engines: Prevents low-temperature ring belt deposits and injector nozzle coking in downsized engines.
Stop-Start Systems: Robust anti-wear films prevent cam lobe scuffing during frequent cold-start cycles.
Hybrid Powertrains: Mitigates fuel dilution (<8%) and moisture accumulation in PHEV applications.
High-Performance Engines: Sustains oil pressure >45psi at 150°C sump temperature during track testing.
ZT73191's patented LSPI inhibitor technology exceeds Sequence IX requirements by 40%, preventing catastrophic connecting rod failure in 2.0L EcoBoost engines. Its balanced detergent/dispersant system maintains top-tier piston cleanliness (TEOST 33C <30mg) without compromising catalyst efficiency, as validated in 160,000-km fleet testing. Formulators benefit from pre-optimized component synergy that reduces total treat rates by 15% versus competitive packages while achieving full ILSAC GF-6A certification. With OEM approvals including Ford WSS-M2C961-A1, GM dexos1® Gen 3, and Fiat 9.55535-GS1, ZT73191 provides field-proven protection backed by comprehensive M111E fuel economy data and complete material safety documentation.
