Spring 2025 Marked Tomoil’s Launch of API SQ-Ready Engine Oils

January 19, 2026

Tomoil continues to lead in lubricant innovation by aligning its next-generation gasoline engine oils with the new API SQ specification, the latest benchmark from the American Petroleum Institute (API), effective May 2025. API SQ represents critical advancements in oil technology, designed to meet the demands of modern high-performance engines.

Key Benefits of API SQ:

Optimized Fuel Efficiency: Reduced internal engine friction helps improve fuel economy.
Enhanced LSPI Protection: Oils are validated for Low-Speed Pre-Ignition (LSPI) even in used oil, safeguarding turbocharged, high-compression engines.
Superior Engine Cleanliness: Stricter oxidation and deposit control requirements minimize piston deposits and maintain performance.
Reduced Sulfated Ash: Maximum 0.9% ash content protects Gasoline Particulate Filters (GPFs) and prevents clogging.
Cold-Start Reliability: Low-temperature viscosity improvements ensure dependable lubrication in harsh conditions.

Support for Ultra-Low Viscosity Oils: Grades like SAE 0W-8 and 0W-12 enable next-generation engines to achieve peak efficiency.

Why Tomoil Adopts API SQ:

Future-Ready Formulations: Engineered for modern turbocharged, direct-injection engines.
Comprehensive Testing: LSPI aged-oil, oxidation, viscosity, and deposit control tests validate each formulation.
Emission System Safety: Protects sensitive components, contributing to cleaner exhaust and compliance with emission standards.

Customer Benefits:

Improved fuel economy without compromising engine protection
Extended engine life through superior LSPI and deposit control
Cleaner emissions with ash-reduced formulations
Confidence in modern engine designs, including downsized turbo and ultra-low viscosity engines
