Engineered to mitigate friction, enhance thermochemical stability, and minimize wear under extreme shear stress.
Established in 2009 in Zibo, Shandong, Shandong Longhai Lubrication Technology Development Co., Ltd. has developed into a premier tribology powerhouse in China. Spanning a 131-acre high-tech manufacturing campus with an annual capacity of 200,000 metric tons, we engineer, synthesize, and export world-class automotive, motorcycle, and industrial lubricants globally.
Under our signature brand "Century Longhai" and through international joint formulations like the British "A Ba" series, we design customized lubrication chemistry. Every product batch is insured by the People's Insurance Company of China (PICC), establishing a foundation of trust, quality control, and zero-defect operational security.
By investing over 5% of our annual revenue directly into chemical research, mechanical modeling, and tribology labs, we support customized formulations for global OEMs. Our product lines meet demanding global specifications including API SP, CK-4, ACEA, and JASO standards.

A technical overview of synthetic molecular engineering designed for high-stress drivetrains.
We combine Group IV Polyalphaolefins (PAO) with structural Group V Esters. This synthetic matrix maintains molecular structure across a wide operating temperature window, ensuring consistent viscosity control.
Designed with lower Sulfated Ash, Phosphorus, and Sulfur (SAPS), our formulas prevent diesel particulate filter (DPF) blocking and catalyst poisoning while protecting exhaust gas aftertreatment systems.
By incorporating shear-stable viscosity index improvers, our synthetic lubricants maintain HTHS (High-Temperature High-Shear) film thickness, preventing metal-on-metal contact under heavy engine loads.
| Performance Parameters | Fully Synthetic (PAO + Ester) | Semi-Synthetic (Hydrocracked) | Conventional Mineral Base |
|---|---|---|---|
| Pour Point (°C) | -45°C to -55°C | -30°C to -38°C | -10°C to -20°C |
| Viscosity Index (VI) | > 175 | 140 - 160 | 95 - 110 |
| Noack Volatility Loss (wt%) | < 6.5% | 9.5% - 13% | > 15% |
| HTHS Viscosity at 150°C (mPa·s) | 3.5 - 4.2 | 2.9 - 3.4 | 2.2 - 2.8 |
| Oxidative Induction Time (OIT) | Excellent (> 90 mins) | Moderate (45 - 60 mins) | Standard (< 25 mins) |
Global procurement agents face challenges related to product consistency, supply chain reliability, regulatory compliance, and total cost of ownership (TCO). Shandong Longhai addresses these operational challenges with industrial-scale solutions:
Addressing the shifting landscape of global manufacturing, emissions standards, and green energy transition.
Modern fleets require fuel-efficient oils that do not sacrifice engine life. Our low-viscosity synthetic formulations (e.g., CK-4 5W-30) lower fluid friction inside heavy-duty diesel engines. This helps transport operators meet Euro VI and EPA standards while improving overall fuel economy.
Our synthetic gear oils and turbine lubricants are designed to protect gearboxes operating in remote, high-stress environments. High viscosity indices and shear resistance protect gear assemblies from micropitting and bearing failure, reducing costly down-time.
The transition to low-GWP refrigerants (CO2, HFOs, Ammonia) requires compatible compressor oils. Shandong Longhai develops refrigeration lubricants that resist chemical degradation and maintain solubility at low evaporator temperatures, ensuring system efficiency.
