With more than 15 years of industry experience, we operate a vertically integrated supply chain, serving industrial operations and transportation sectors globally.
Our proprietary brand, "Century Longhai", along with our strategic international partnership line (British "A Ba" series), represents high-performance standards in global lubrication. Our products cover diesel engine oil, gasoline engine oil, gear oil, hydraulic transmission oil, anti-wear hydraulic oil, specialized engineering machinery formulations, natural gas engines oil, full synthetic formulations, automotive urea solution, antifreeze, and high-performance four-stroke motorcycle oils. The stability of our products is further guaranteed by quality insurance underwritten by PICC (People's Insurance Company of China).
Accelerating global procurement through scale, cutting-edge synthesis, and precision quality assurance protocols.
Our production facilities span 131 acres, yielding an annual capacity of 200,000 tons. Equipped with fully intelligent blending platforms and automated filling systems, we serve high-volume orders with consistency and speed.
We reinvest over 5% of annual revenue directly into our internal laboratories and joint innovation centers. Partnering with top chemical institutes, we continuously refine oil shear resistance, molecular durability, and green formulations.
Using digital metering, our filling lines maintain a precision margin between 1‰ and 2‰. By increasing production speeds by 20% to 35%, we drastically decrease bulk order turnaround times.
Product quality, process safety, and environmental stewardship define Longhai. We have successfully completed rigorous testing frameworks to hold major industrial credentials, ensuring our products perform consistently under high friction and extreme thermal states.
Our credentials include ISO 9001:2015 Quality Management System Certification, ISO 14001 Environmental Management, and OHSAS 18001 Health and Safety Management. Additionally, our fluid lines carry specialized Mercedes-Benz transmission approval, confirming compliance with leading European passenger vehicle requirements.
From custom viscosity adjustments to retail package styling, we design lubricants to fit your regional market demands and operating climates.
Our engineers adjust synthetic bases (Group III, PAO, Ester options) to fit API (SP, SN, CK-4, CJ-4) and ACEA specifications. Whether your markets face sub-zero Arctic temperatures or desert heat, we modify viscosity indexes to deliver optimal wear protection.

Modern internal combustion engines generate high mechanical pressures, pushing engine oils to their limits. Formulating synthetic oil requires balancing base oils and specialized additive packages to prevent premature breakdown.
Viscosity Index (VI) Dynamics: Highly refined Group III base stocks, enhanced with Polyalphaolefins (PAO), yield a natural high Viscosity Index. This ensures flow remains fluid in cold environments while maintaining a protective oil film at high operating temperatures, reducing friction and engine wear.
Low-Speed Pre-Ignition (LSPI) & Wear Control: Modern turbo gasoline direct-injection engines (TGDI) are prone to LSPI, which can damage cylinder components. Our newer SP-grade formulations are engineered with balanced calcium and magnesium levels, reducing the risk of LSPI while protecting timing chains from wear.
Advanced Soot Management: Commercial diesel engines generate significant soot, which can clump and cause wear. Our API CK-4 and CJ-4 formulations contain advanced dispersant molecules that keep soot suspended, preventing abrasive wear and keeping engines clean.

Engineered for specific mechanical demands, our industrial range ensures system efficiency and equipment durability.
Our specialized formulations are engineered to deliver reliable lubrication and wear protection across diverse operating environments.
Fleet operators require oils that can handle extended drain intervals while keeping engines clean. Our API CK-4 and CJ-4 formulations contain advanced dispersants that prevent soot buildup, protecting commercial diesel engines over long distances.
Motorcycle engines operate at higher RPMs and temperatures than passenger cars, sharing lubricant with the gearbox. Our specialized 4-stroke formulations feature high shear stability, protecting wet clutches and gear teeth under heavy acceleration.
Manufacturing plants rely on hydraulic pumps and gearboxes working under extreme load. Our anti-wear hydraulic fluids and L-CKD heavy-duty gear oils contain specialized additives that prevent component micro-pitting, keeping industrial lines running smoothly.
Transitioning to Low-Viscosity Oils: To improve fuel efficiency and lower emissions, modern engine manufacturers are designing tighter tolerances that require thinner oils like 0W-16 and 0W-20. Maintaining wear protection with lower viscosities requires advanced synthetic base oils and highly stable polymers.
Eco-Friendly & Biodegradable Formulations: As environmental regulations tighten, industries are shifting toward biodegradable hydraulic fluids and industrial gear oils. Our R&D team is actively formulating high-performance, renewably sourced options that reduce environmental impact without sacrificing component protection.
Lubricants for Hybrid Powertrains: Hybrid vehicles run their combustion engines intermittently, leading to lower operating temperatures and higher moisture risk. We are developing specialized low-viscosity formulations that resist moisture buildup and prevent corrosion in hybrid engines.
Detailed answers to common questions about oil specifications, wholesale procurement, and OEM customization.
API SP is the current passenger car specification, introduced to provide superior protection against Low-Speed Pre-Ignition (LSPI) in modern turbocharged gasoline direct-injection (TGDI) engines. Compared to API SN, SP-grade oils offer improved wear protection for timing chains, better oxidation stability, and enhanced deposit control.
ISO 9001 and IATF 16949 are strict quality management standards designed for the global automotive supply chain. These certifications ensure that every batch of oil is blended with consistent base oils and additives, maintaining the specified viscosity and performance standards across high-volume production runs.
Every production run undergoes strict quality checks in our testing labs. We verify critical properties like High-Temperature High-Shear (HTHS) viscosity, Cold-Cranking Simulator (CCS) viscosity, and Noack volatility to confirm each batch meets our technical specifications before packaging.
Yes. Our R&D team can adjust base oils and polymers to optimize formulations for specific regional climates. We can develop oils with excellent low-temperature flow properties for sub-zero regions, or high-viscosity formulations for high-heat environments.
