Precision-engineered lubricant formulations designed to protect and optimize the power delivery of leading two-wheeler engines and heavy industrial powertrains.
Established in 2009 and headquartered in the industrial hub of Zibo, Shandong, Shandong Longhai Lubrication Technology Development Co., Ltd. has evolved into a premier high-tech enterprise integrating R&D, advanced manufacturing, and global sales. For over 15 years, we have meticulously built an integrated chemical and lubrication supply chain designed to power global industrial machinery, automotive transport, and particularly, the high-performance demands of two-wheeler engines.
Under our own flagship brand, "Century Longhai", and through our strategic international partnership with the British "A Ba" series, we produce a comprehensive catalog. Our product portfolio spans high-performance diesel engine oils, gasoline engine oils, specialized motorcycle oils, industrial gear systems, transmission fluids, and anti-wear hydraulic oils. To give our global distributors complete peace of mind, all products carry quality underwriting insured by PICC (People's Insurance Company of China).
The global two-wheeler sector is undergoing massive changes due to environmental rules and technology advances. Modern two-wheeler engines operate under extreme conditions: higher operating RPMs (often exceeding 10,000 RPM), smaller oil sump capacities, and high power-to-displacement ratios. This results in extreme thermal stress and shear forces that degrade standard engine lubricants rapidly.
Unlike passenger cars, many two-wheelers rely on air-cooled engines. In congested urban traffic, engine temperatures can spike, demanding fluids with high thermal stability and shear protection to prevent metal-on-metal wear.
Most motorcycles integrate the engine, gearbox, and wet clutch in a single oil sump. The lubricant must balance low friction for fuel efficiency with high friction coefficients (JASO MA2 specs) to prevent clutch slippage.
Tighter emission standards force OEM engine builders to use advanced exhaust catalysts. Lubricants must contain lower levels of Sulfated Ash, Phosphorus, and Sulfur (SAPS) to avoid poisoning these catalytic systems.
Large-scale commercial buyers, regional distributors, and fleet owners need suppliers that deliver stable quality, customizable performance, and reliable logistics. Shandong Longhai Technology meets these needs with structured B2B OEM/ODM solutions:
We tailor viscosity profiles, additive chemistries, and synthetic base oil ratios (Group II, III, PAO, and Esters) to match specific climate zones and heavy load profiles. This ensures optimal engine safety and maximum oil-change intervals.
From 1L bottles for retail shelves to 200L drums for industrial workshops, our packaging lines support automated labeling and customized bottling designs. We help partners establish a premium shelf presence.
Every batch is verified in our precision laboratory. We provide detailed certificates of analysis (COA) for all variables, including viscosity index, total base number (TBN), flash point, and pour point.
We offer full-service white-label manufacturing, allowing global brands to launch high-performance lubricants without expensive production overheads. Our manufacturing infrastructure is designed to scale quickly based on market demands.
At Shandong Longhai Technology, we use advanced production technologies to ensure high capacity and reliable quality. Our plant features automated metering systems and high-precision filling lines, allowing us to keep prices competitive while maintaining consistent quality.
Our automated blending setups use real-time sensors to maintain precise mixing temperatures, blending speeds, and additive levels. This prevents variances between production batches.
Using advanced mass-flow metering systems, our automated filling lines achieve a high accuracy rate of 1‰-2‰, significantly reducing waste and increasing bottling speeds by up to 35%.
We source high-quality base oils and additives from globally recognized petrochemical suppliers. This strong supply chain keeps our production running consistently during market fluctuations.
Different regions and industries demand customized lubrication strategies. Here is how Longhai fluids perform across varied settings.
In high-traffic urban areas, delivery two-wheelers face constant stop-and-start driving. This causes rapid thermal loading and potential oil shearing. Longhai motorcycle oils are formulated with high shear-stable polymers, maintaining viscosity and protecting wet clutches even during extended city routes.
Industrial machinery operating in dusty, high-load mining environments requires robust protection. Our premium hydraulic transmission fluids and heavy-duty diesel oils contain detergent and anti-wear additives that keep contaminants suspended, helping to prevent abrasive wear on gears and cylinders.
Moisture and salt-air accelerate oxidation and corrosion. Longhai anti-wear hydraulic and industrial gear oils are treated with advanced rust inhibitors, protecting metal surfaces from corrosion and maintaining hydrolytic stability in wet environments.
Quality stability is the core of our brand. Shandong Longhai Lubrication Technology has passed rigorous international standards, including ISO 9001:2015 Quality Management System certification, ISO 14001 Environmental Management System certification, and ISO 45001 Occupational Health and Safety Management System certification. In addition, our high-quality automatic transmission fluids have received official Mercedes-Benz approval, showing our ability to meet strict OEM guidelines.
Through strict quality audits, we ensure that every drum of oil performs reliably under extreme conditions, helping customers reduce maintenance costs and improve operational uptime.
How we work with global B2B buyers from initial consultation to final volume distribution.
We collaborate to identify targeted applications, engine specs, climate requirements, and regulatory standards for your target market.
Our chemists adjust synthetic and mineral base oil formulations with selected additive packages, tailoring the fluid to your needs.
