Engineered for high thermal loads, boundary lubrication protection, and operational efficiency under extreme industrial operations.
For over 15 years, Shandong Longhai Lubrication Technology has served as a central node in the global high-performance lubricants ecosystem. Based in Zibo, Shandong, our facility integrates raw material synthesis, advanced formulation development, dynamic high-capacity blending, and extensive laboratory testing.
We manage our flagship proprietary brand, "Century Longhai", while sustaining a long-term strategic partnership with the premium British "A Ba" series. In a market where chemical integrity corresponds directly to equipment lifespan, our complete product range—covering synthetic diesel and gasoline motor oils, industrial and marine gear oils, high-shear hydraulic transmission fluids, and special engine oils—is insured by PICC (People's Insurance Company of China). This insurance acts as a direct performance guarantee, ensuring total risk mitigation for industrial operators worldwide.

Analyzing the performance gaps between traditional mineral formulations and next-generation synthetic alternatives in heavy-duty setups.
Modern heavy machinery operates under extreme pressures, higher power densities, and tighter physical dimensions. These trends have pushed traditional Group I and Group II mineral gear oils to their thermal limits. Under heavy loads, mineral-based oils experience rapid shear degradation and high-temperature oxidation, resulting in sludge buildup, micropitting, and gearbox failures.
Shandong Longhai's Full Synthetic Gear Oils resolve these challenges through custom molecular design:
| Performance Property | Conventional Mineral Oils (Group II) | Longhai PAO Full Synthetic Gear Oils | Operational Value-Add |
|---|---|---|---|
| Operating Temp Range | -15°C to 90°C | -45°C to 160°C | Eliminates the need for seasonal oil changeouts in extreme climates. |
| Viscosity Index (VI) | 90 - 105 | 160 - 190+ | Prevents oil thinning at high heat; ensures fluid flow at sub-zero. |
| Oxidation Lifetime (TOST) | 1,500 - 2,500 hours | 10,000+ hours | Extends oil drain intervals up to 4x, lowering operational downtime. |
| Micropitting Resistance | Moderate/Low | High (Class FLS 12+) | Protects precision gear teeth in heavy machinery from premature wear. |
How Shandong Longhai is pioneering formulations to meet next-generation industrial demands and ESG criteria.
Developing extreme-pressure (EP) additive packages that form chemical barrier layers at a molecular level. This target prevents micro-pitting fatigue in high-load planetary gears used in wind energy and heavy mining applications.
Aligning with global ESG directives, our R&D team is scaling bio-derived synthetic esters that deliver equivalent lubrication capabilities while breaking down safely in offshore drilling and forestry environments.
Integrating insulation and heat transfers within synthetic lubricants. Our ultra-low viscosity synthetic gear oils offer oxidation protection for electric vehicle motors running up to 20,000 RPM.
Customizing lubrication solutions to match specific industrial and environmental operating conditions worldwide.
In offshore wind farms across Northern Europe and the Arctic Circle, extreme cold causes conventional lubricants to wax and gel. Longhai's PAO gear oils, featuring flow points down to -45°C, remain fluid during startup, protecting gearboxes and ensuring clean power generation.
Deep mines and hot strip steel mills subject gearboxes to heavy shock loads, dust, and high temperatures. Longhai's L-CKD heavy-duty gear oils contain specialized sulfur-phosphorus anti-wear packages that prevent scoring and steel-on-steel welding under extreme loads.
Marine cranes, container ships, and port winches face constant exposure to salt air and water contamination. Our synthetic formulations incorporate advanced demulsifiers that rapidly separate water from the oil, preventing internal component rust and acid wear.
Operating a 131-acre manufacturing center with high-precision blending lines and quality assurance validation.
Shandong Longhai Lubrication Technology invests over 5% of its annual revenues back into laboratory development and automation. Our modern facility features fully automated batch blending platforms that maintain precise additive-to-base-oil ratios within a strict 1‰ - 2‰ margin of error.
This precision ensures that every batch of gear oil produced matches the chemical composition developed in our laboratories. In addition, the integration of high-speed automatic filling lines has improved our production efficiency by 20% to 35%, ensuring short lead times for international orders.
Our facility operates under a strict Integrated Management System (IMS), carrying verified certifications across global benchmarks:






A step-by-step engineering pathway from initial viscosity design to final packaged formulation delivery.
We develop fully synthetic and semi-synthetic lubricant formulations tailored to your vehicle or equipment requirements, climatic conditions, or target market positioning. Our engineering team designs oils to meet or exceed international standards like API, ACEA, AGMA, and custom OEM specifications.
Whether you require a dedicated high-load ISO VG 320 wind turbine oil or a fuel-efficient EV gear oil, we provide small-scale trial production runs prior to high-volume manufacturing, helping mitigate developmental risk.
