Explore our high-performance B2B engine and industrial lubrication solutions, certified to perform under extreme load conditions.
Established in 2009 and headquartered in Zibo, Shandong, Shandong Longhai Lubrication Technology Development Co., Ltd. is a national high-tech enterprise integrating R&D, production, and global sales. For over 15 years, we have built a complete industrial chain system dedicated to providing high-quality lubrication solutions for the global industrial and transportation fields.
As a reliable lubricant manufacturer, Longhai Technology owns its own brand "Century Longhai" and the international strategic cooperation brand British "A Ba" series of products. Our versatile portfolio covers diesel engine oil, gasoline engine oil, gear oil, hydraulic transmission oil, anti-wear hydraulic oil, special engine oil for engineering machinery, special oil for natural gas, full synthetic oil, automotive urea solution, antifreeze, special engine oil for motorcycles, industrial oil, and automatic transmission oil.
Safety and reliability are guaranteed: the brand is insured by PICC China People's Insurance Company, offering complete quality insurance and risk management support for international buyers.
How we leverage high-tech automated equipment and geographic location to deliver high-quality lubricants at competitive wholesale prices.
Longhai Technology's production base spans 131 acres, with an annual capacity of 200,000 tons. Equipped with fully automatic blending and filling production lines, we maximize efficiency and consistency. The filling line utilizes high-precision metering systems that guarantee a filling accuracy of 1‰-2‰. Under strict quality control parameters, our automated infrastructure speeds up delivery times by 20%-35% compared to standard batch blending methods.
Located in Zibo, Shandong Province, we operate in the heart of China’s chemical and industrial manufacturing cluster. This provides direct access to high-quality base oils (Group I, II, and III synthetic bases) and raw additives. Coupled with close proximity to major international ports like Qingdao Port, we offer optimized shipping logistics, reduced ocean freight rates, and seamless customs clearance procedures for our global B2B procurement partners.
Demystifying the science behind formulation design: why 4-stroke motorcycle engines demand specialized, high-shear lubrication.
Unlike passenger car engines, modern 4-stroke motorcycles utilize a unified sump that lubricates the engine, transmission, and wet clutch. Our 4T oils are engineered to offer high friction performance, preventing clutch slippage under high loads while meeting strict JASO T 903:2016 MA2 test specifications.
Motorcycle engines operate at significantly higher speeds (often exceeding 10,000 RPM) than passenger cars. Using viscosity index improvers with superior shear stability prevents chemical breakdown, maintaining the oil film thickness and protecting gearbox gears from micro-pitting.
Air-cooled and high-performance liquid-cooled motorcycle engines generate extreme thermal stress. Shandong Longhai's synthetic and semi-synthetic formulations resist oxidation, control piston deposit formation, and ensure engine cleanliness under hot climates.
Global distribution requires compliance with local environmental laws, international transportation standards, and manufacturer approvals.
Shandong Longhai Technology Development Co., Ltd. has successfully passed ISO 9001:2015 Quality Management, ISO 14001:2015 Environmental Management, and ISO 45001:2018 Occupational Health and Safety Management system certifications. Furthermore, our premium automatic transmission fluid holds official Mercedes-Benz approvals, demonstrating our capability to meet rigorous European OEM specifications.
Every batch of lubricating oil exported undergoes strict laboratory analysis, testing core parameters including cold cranking viscosity (CCS), kinematic viscosity at 40°C/100°C, viscosity index, flash point, pour point, and total base number (TBN).
Empowering global oil brands, regional distributors, and motorcycle manufacturers with end-to-end bespoke packaging and custom viscosity formulations.
We customize fully synthetic, semi-synthetic, and premium mineral oil chemistry tailored to specific regional climates, vehicle type populations, or market-driven pricing structures. We support formulations meeting API SP/SN/SL/SJ and JASO MA2/MB specifications.
From 1-Liter and 4-Liter retail bottles to 18-Liter pails and 200-Liter industrial drums, we provide extensive custom mold options, custom color schemes, and multi-language label printing complying with GHS and local trade guidelines.
Define product standard (API/JASO), viscosity grades, volume, target market parameters, and target pricing.
Engineers design customized chemical additive and base oil blends matching customer specifications.
We supply analytical samples for physical testing and compliance assessment in the client's lab.
Automated high-precision blending and packing under ISO standards, aiming for 100% batch consistency.
