Shandong Longhai Lubrication Technology Development Co., Ltd. was established in 2009 and is headquartered in Zibo, Shandong. As a high-tech enterprise integrating R&D, production, and sales, the company has been deeply involved in the lubricant industry for more than 15 years, building a complete industrial chain system dedicated to providing high-quality lubrication solutions for the global industrial and transportation fields.
Longhai Technology owns the domestic brand "Century Longhai" and the strategic cooperation brand British "A Ba" series. Our extensive product portfolio covers diesel engine oil, gasoline engine oil, gear oil, hydraulic transmission oil, anti-wear hydraulic oil, engineering machinery engine oil, natural gas engine oil, fully synthetic oil, automotive urea solution, antifreeze, motorcycle engine oil, industrial oils, and automatic transmission fluids. Our brand's performance reliability is backed by comprehensive product liability insurance insured by PICC (China People's Insurance Company), giving global partners ultimate peace of mind.
The company has passed ISO-9001-2015 quality system certification, 14001 environmental management system certification, and 18001 health management system certification. Our premium products have also acquired prestigious original equipment manufacturer (OEM) endorsements, including Mercedes-Benz certification, ensuring maximum product quality and stability.
By strictly adhering to international standards and incorporating advanced blending processes and testing technologies, we ensure that our lubricants provide top performance under extreme temperatures, high friction, and heavy load conditions, helping global enterprises reduce operational down-time and extend equipment life.
China's manufacturing scale, coupled with Shandong's petrochemical supply chains, offers structural advantages for bulk importers and distributors.
Longhai utilizes state-of-the-art automatic blending technology and metering filling equipment. By ensuring a precise volume filling accuracy of 1‰ to 2‰, we mitigate material waste while boosting production speeds by 20% to 35%. This guarantees that large-scale global shipments are completed with speed, standard conformity, and minimal lead times.
Innovation-driven growth lies at our core, with annual R&D investment consistently exceeding 5% of our revenue. We collaborate with leading research institutions to refine lubricant formulas on a molecular level, offering excellent shear stability, high viscosity indices, and high thermal oxidation resistance tailored for modern vehicles.
Situated in Zibo, Shandong, our facility lies adjacent to massive petrochemical refining hubs and deepwater logistics ports (Qingdao). This proximity grants us access to premium Group II, III, and IV base oils and globally recognized additives, allowing us to deliver wholesale cost efficiencies to global distributors without compromising on quality.
The lubrication landscape is shifting rapidly due to emissions regulations, low-viscosity requirements, and new drivetrain layouts.
To combat global emissions and optimize fuel economy, automotive OEMs are trending toward low-viscosity oils (such as 0W-20, 0W-16, and even 0W-12). This transition demands extremely robust base oils and advanced additive packages that maintain fluid film strength under high-shear, high-temperature (HTHS) conditions.
Furthermore, modern turbocharged gasoline direct injection (TGDI) engines require compliance with the latest API SP and ILSAC GF-6 specifications. These standards provide critical protection against Low-Speed Pre-Ignition (LSPI) and timing chain wear. Shandong Longhai's laboratory actively develops next-generation formulations to protect downsized engines operating under severe thermal loads.
From extreme geographic environments to specialized industrial operations, our custom formulations deliver optimal wear protection.
Scenario: Extreme temperatures (such as Russia, Northern Europe, or Middle Eastern deserts).
Our fully synthetic 0W and 5W multi-grade oils leverage premium pour-point depressants and shear-stable polymer viscosity modifiers, ensuring fast starter motor cranking and flow at -40°C, while maintaining viscosity thickness at +50°C ambient temperatures.
Scenario: Commercial diesel transport fleets demanding extended oil drain intervals (ODIs).
Using our heavy-duty API CK-4 and CJ-4 formulations (such as the Longhai CI-4 PLUS Premium Diesel Oil), logistics fleets achieve extended drain intervals, soot dispersion, and piston-deposit protection, reducing routine maintenance cycles.
Scenario: Extreme mechanical pressure in construction and metal manufacturing equipment.
Our wholesale anti-wear hydraulic oils are engineered with high thermal stability and zinc-based anti-wear additives. This prevents vane and piston pump wear under extreme pressures, improving mechanical power transmission efficiency.
We offer turnkey private label solutions, from custom chemical synthesis to retail packaging design.
We develop fully synthetic and semi-synthetic lubricants tailored to target market demands, extreme regional climates, or specified specifications, ensuring compliance with API, ACEA, and JASO standards.
From small trial runs to massive container-load batches, our flexible blending plant supports diesel engine oils, gasoline motor oils, gear fluids, and refrigeration system oils in varying packaging sizes.
Operating under strict ISO 9001 and IATF 16949 parameters, every batch undergoes laboratory testing. We supply complete Certificates of Analysis (COA) and material safety data sheets (MSDS) for import clearance.
We provide full branding assistance, including customized plastic canister molding, metal drum printing, label compliance reviews, and multilingual documentation for smooth cross-border distribution.

Technical answers on specifications, formulations, quality metrics, and importing logistics from Shandong Longhai.
We determine product performance through standard metrics, including high-temperature high-shear (HTHS) viscosity, cold-cranking simulator (CCS) viscosity, Noack volatility (oil evaporation loss), total base number (TBN) reserve, and shear stability index (SSI). Our state-of-the-art laboratory analyzes every batch to ensure conformity with API SP/SN and ACEA requirements before it leaves the factory.
Our API SP-compliant lubricants utilize customized additive chemistry, reducing calcium-based detergents and incorporating magnesium-based detergents and molybdenum anti-wear compounds. This chemical configuration stops abnormal combustion events in turbocharged direct-injection (TGDI) cylinders, preventing severe engine damage.
L-CKC medium-load gear oil is developed for standard industrial gearboxes operating under mild to moderate pressure, protecting against sliding friction. L-CKD heavy-duty gear oil is formulated with extreme-pressure (EP) additives and anti-micropitting chemistry, designed to protect gearteeth under extreme shock loads, high temperatures, and wet environments.
Our manufacturing base holds ISO 9001:2015 for quality management, ISO 14001:2015 for environmental protection, and ISO 45001:2018 (previously OHSAS 18001) for occupational health and safety. Furthermore, our automatic transmission lubricants carry official Mercedes-Benz approvals, validating their compliance for international markets.
For initial OEM formulations requiring customized packaging, development and label approval takes 15 to 20 days. Once the formulation and design are approved, automated blending and high-speed filling lines complete production in 10 to 14 days, supported by our 1‰-2‰ filling precision technology.
Quality control starts with pre-shipment laboratory analysis, generating a traceable batch number. Furthermore, our products are backed by comprehensive liability coverage insured by PICC (People's Insurance Company of China), providing compensation and compliance security for our buyers.
