Explore our advanced catalog of industrial engine and machinery fluids engineered for extreme operations.
Established in 2009 and headquartered in Zibo, Shandong, China, Shandong Longhai Lubrication Technology Development Co., Ltd. has spent over 15 years developing custom, high-technology heavy-duty diesel oils and industrial fluids. We integrate cutting-edge Research & Development, highly automated blending systems, and a strict compliance regime to support global transport, mining, engineering, and energy markets.
Longhai operates its flagship domestic brand "Century Longhai" alongside the premium international strategic brand British "A Ba" series. Our comprehensive product assortment features API-certified CK-4, CJ-4, CI-4 Plus, and CH-4 heavy-duty diesel engine oils, high-performance transmission fluids, extreme-pressure gear oils, wear-resistant hydraulic lubricants, natural gas engine oils, automotive urea solutions, antifreeze, and motorcycle lubricants. The exceptional quality of the Century Longhai brand is backed by comprehensive product liability coverage through the PICC People's Insurance Company of China.
How regulatory shifts and engineering breakthroughs are shaping the next generation of engine lubrication.
Commercial fleet operators are moving rapidly from traditional 15W-40 oils to high-performance fuel-economy grades like 10W-30 and 5W-30. Advanced synthetic bases maintain proper HTHS (High-Temperature High-Shear) oil film thickness while significantly reducing boundary friction losses, improving fuel economy by 1.5% to 3%.
Strict Euro VI and China VI regulations dictate the use of Low-SAPS (Sulfated Ash, Phosphorus, and Sulfur) lubricants. Our formulations prevent DPF (Diesel Particulate Filter) poisoning and SCR catalyst deactivation, ensuring heavy vehicles consistently meet emissions requirements over hundreds of thousands of kilometers.
Industrial procurers evaluate engine lubricants through a TCO (Total Cost of Ownership) lens. Modern heavy-duty oils utilize robust antioxidant and base reserves (TBN) to delay thermal breakdown. Our synthetic engine oils routinely extend service intervals, keeping machines in service longer.
Longhai Lubrication Technology's manufacturing complex in Zibo spans 131 acres, utilizing smart Factory 4.0 elements to achieve an annual production output of 200,000 metric tons. Our production facility is equipped with automated mass-flow batch-blending control systems and a series of high-speed filling lines.
By using precision volumetric metering technology on our lines, we achieve a filling accuracy rate of 1‰ to 2‰. This advanced control system increases average packaging speeds by 20% to 35%, ensuring reliable order turnaround, precise weight checks, and reliable quality for bulk distribution.
Located near the deepwater port of Qingdao and integrated into Shandong's industrial corridors, Longhai maintains direct supply relationships for high-quality base oils (Group II, III, and IV PAO) and additive systems from major international manufacturers (Infineum, Lubrizol, Afton, Chevron Oronite). This vertical integration provides pricing stability and reliable production continuity during global supply constraints.
Our lubricants are custom-formulated to operate reliably in diverse climates and industrial sectors.
High-speed, long-distance interstate transport requires lubricants with exceptional thermal stability. Our API CK-4 engine oils help prevent sludge buildup, minimize soot-related wear, and protect valvetrains, allowing transport fleets to confidently plan extended maintenance cycles.
Heavy-duty machinery in open-pit mining operates under extreme mechanical shear, heavy dust, and high loads. Our high-viscosity index formulations protect critical journal bearings, hydraulic systems, and final drives under high operating pressures.
Our synthetic 5W-30 and 5W-40 heavy-duty engine lubricants are engineered for rapid cold-weather start-up oil flow, protecting components in sub-zero climates while maintaining adequate film strength at high engine operational temperatures.
Longhai Lubrication Technology operates under a comprehensive quality management framework. We are certified to ISO 9001:2015 for quality management, ISO 14001:2015 for environmental compliance, and ISO 45001:2018 for occupational health and safety standards.
Our formulas meet international performance standards set by the API (American Petroleum Institute), ACEA (European Automobile Manufacturers' Association), and major global OEMs. In addition, our automatic transmission and gear lubricants carry formal OEM approvals, including Mercedes-Benz certification, validating their compatibility and performance in critical commercial components.
From custom chemical blending to packaging design, we deliver complete lubrication solutions.
Our laboratory engineers synthetic, semi-synthetic, and mineral base lubricants tailored to specific fleet requirements, local operating climates, or regional API/ACEA compliance standards.
Our packaging lines support a wide range of formats, including 1-liter canisters, 4-liter retail bottles, 18-liter pails, 200-liter metal drums, and intermediate bulk containers (IBC totes).
Every production batch is tested in our quality control laboratory using ASTM-compliant testing methods to verify kinematic viscosity, viscosity index, TBN retention, and cold-cranking performance.
We provide complete regulatory documentation, including Technical Data Sheets (TDS), Safety Data Sheets (SDS), and packaging design support, to streamline international customs clearance.
Evaluation of fleet specifications, viscosities, and regional regulatory compliance.
Blending optimization using selected base oils and specialized additive packages.
Laboratory testing to verify high-temperature shear stability and pour point properties.
