High-performance formulations engineered to maximize protection, improve fuel economy, and reduce component wear under extreme operating parameters.
Decoding how the shift toward low-viscosity formulations, emission regulations, and turbocharging affects the demands placed on modern petrol engine oils.
Modern internal combustion engines require more advanced chemical structures than older specifications could provide. The API SP specification represents a substantial technology leap designed to combat Low-Speed Pre-Ignition (LSPI) in Turbocharged Gasoline Direct Injection (TGDI) engines, preventing catastrophic piston damage while offering unmatched wear protection and soot control.
In response to global carbon emission goals, the market is quickly moving from traditional high-viscosity lubricants to ultralow-viscosity synthetics (0W-16, 0W-20). Lowering viscosity decreases internal engine drag, improving fuel economy. Our synthetic chemistry utilizes advanced organic polymer friction modifiers to maintain a strong load-bearing oil film even at minimal thickness.
High-quality engine oil is no longer just a consumable; it is a critical engineering component. Long-life synthetic formulations help reduce downtime, extend oil drain intervals (ODIs) from 5,000 km to over 15,000 km, and reduce the environmental footprint by minimizing waste oil generation. This shift drastically improves the total cost of ownership (TCO) for commercial operators.

For more than 15 years, our company has built a complete industrial chain system dedicated to providing premium lubrication solutions for global industrial and transport applications.
We own the domestic brand "Century Longhai" alongside the international strategic brand, British "A Ba" series. Our comprehensive product portfolio covers gasoline engine oil, diesel engine oil, gear oil, hydraulic transmission oil, anti-wear hydraulic oil, specialized engineering machinery lubricants, natural gas engine oil, automotive urea solutions, antifreeze, motorcycle oil, and industrial lubricants.
To assure our partners of absolute safety and compliance, our brand products are backed by liability insurance issued by the PICC (People's Insurance Company of China), guaranteeing strict quality compliance and risk protection.
Underpinning our product consistency is a modern factory floor engineered for high precision and zero contamination risk.
Our facility features closed-loop automated blending units. Computerized mass-flow controllers monitor raw material injection, ensuring base oils and additive packets are combined at precise temperatures to guarantee stable molecular structures.
By adopting the metering filling principle, our lines achieve a filling accuracy tolerance of 1‰ to 2‰. This setup boosts throughput speeds by 20% to 35%, ensuring quick lead times for high-volume orders.
Our on-site testing laboratory verifies every batch of lubricating oil. Using gas chromatography, ICP spectrometers, and kinematic viscometers, we ensure every drop conforms strictly to target specifications before leaving the factory.
We maintain a stringent quality system, having obtained key global certifications to guarantee safety and performance across automotive and industrial sectors.

Answers to common questions regarding formulation standards, export logistics, and OEM/ODM options.
API SP was introduced to meet modern engine demands, specifically targeting turbocharged direct-injection (TGDI) powerplants. SP oils provide enhanced protection against Low-Speed Pre-Ignition (LSPI), improved timing chain wear mitigation, superior oxidation stability, and better control over piston deposits compared to the older API SN standard.
Yes. Our R&D laboratory designs lubricants for specific climates. For extreme sub-zero regions, we use high-viscosity-index base oils (Group III/IV PAO) and cold-flow pour point depressants to formulate 0W-20, 0W-30, or 0W-40 oils that ensure reliable engine startup protection down to -40°C.
Our facility operates under an ISO 9001:2015-certified quality system. We employ automated blending lines with accurate mass flow control systems to ensure exact additive ratios. Every production batch undergoes testing for viscosity index, flash point, TBN, and shear stability before packaging.
