Advanced Protection Products Formulated for Modern Powertrains and High-Load Industrial Operations
Established in 2009 and headquartered in the industrial hub of Zibo, Shandong, Shandong Longhai Lubrication Technology Development Co., Ltd. has developed into a premier high-tech enterprise integrating research and development, smart manufacturing, and comprehensive distribution of high-performance lubricants. Over more than 15 years of focused expansion, the company has established a vertically integrated industrial chain, cementing its reputation as a leading supplier of global tribological solutions.
Operating under our proprietary domestic brand "Century Longhai" and representing our premium international strategic cooperation brand—the British "A Ba" series—our product portfolio covers a extensive spectrum of lubrication requirements. Our formulations protect critical components in diesel and gasoline engines, industrial gear systems, refrigeration compressors, turbines, and hydraulic equipment, as well as providing specialized fluids such as automotive urea solutions, coolants, and motorcycle lubricants.
To assure our global procurement partners of absolute supply chain reliability, our products carry quality and liability insurance underwritten by the People's Insurance Company of China (PICC). This insurance backing, combined with strict adherence to international standards, guarantees performance stability and operational peace of mind across demanding light-duty and heavy-duty applications.
Why Global Distributors and OEMs Partner with Shandong Longhai for Bulk Lubricant Supply
Our facility utilizes state-of-the-art metering blending technologies. Standardizing workflows with high-accuracy dosing instruments guarantees blending precision limits to within 1‰ to 2‰. Our automated lines increase packaging and filling speeds by 20% to 35% over standard lines, ensuring rapid batch transitions and prompt delivery timelines.
Located in Zibo, Shandong—a major national hub for refining and chemical processing—Longhai enjoys immediate supply security for premium Group I, II, and III base stocks. This local pipeline and terminal network minimizes internal shipping freight costs, providing global procurement managers with distinct pricing leverage.
Quality control is foundational to our operations. Shandong Longhai is certified under ISO 9001:2015 (Quality Management), ISO 14001:2015 (Environmental Management), and ISO 45001:2018 (Occupational Health). Additionally, our fluids hold prestigious OEM approvals, including automatic transmission fluid certifications from Mercedes-Benz.
Modern gasoline engines operate under tighter tolerances, higher thermal conditions, and increased pressures, driven by technologies such as gasoline direct injection (GDI) and turbocharged gasoline direct injection (TGDI). To combat these challenges, petrol engine oils must deliver more than simple fluid film barrier protection. They require sophisticated chemical additives to manage soot, prevent low-speed pre-ignition (LSPI), and reduce wear on timing chains and valvetrains.
At Shandong Longhai, our premium formulations (such as our SP and SN grade fully synthetic oils) are designed with high-quality synthetic base stocks (Group III and PAO) combined with optimized additive packages. These chemistries incorporate:
Shandong Longhai provides comprehensive contract manufacturing services to allow private labels, international distributors, and vehicle brands to build customized product lines. We offer tailored services from formulation engineering to final retail packaging.
We formulate synthetic, semi-synthetic, and mineral products to match specific viscosity requirements (e.g., 0W-16, 0W-20, 5W-30, 10W-40) and performance specs (API, ACEA, JASO, OEM standards).
Whether shipping in 1L bottles for retail, 4L/5L jugs for automotive workshops, or 200L drums and IBC totes for industrial users, our automated packaging lines accommodate a wide range of vessel specifications.
Every batch undergoes testing in our precision laboratory. We verify critical parameters, including kinematic viscosity, viscosity index, flash point, pour point, CCS (cold cranking simulator), and Noack volatility.
Formulating Performance Across Transportation, Infrastructure, and Heavy Industrial Operations
Heavy-duty logistics operations demand lubricants that protect diesel engines under continuous thermal load. Our CJ-4, CK-4, and CI-4 synthetic and semi-synthetic diesel engine oils reduce soot-induced wear, maintain shear stability, and optimize fuel economy over extended drain intervals.
Hydraulic systems and heavy-duty gearboxes operate under high loads and shock conditions. Our anti-wear hydraulic fluids and industrial gear oils (L-CKC and L-CKD) provide high film strength, demulsibility, and oxidative stability, preventing system cavitation and mechanical wear.
Specialized refrigeration compressors and power generation turbines require chemical stability. Our professional-grade refrigeration lubricants and high-efficiency turbine oils resist oxidation and sludge formation, ensuring system reliability and lower maintenance costs.
For global procurement departments, selecting a lubricant manufacturer is a complex process. Key priorities include pricing, chemical consistency, packaging durability, and supply chain logistics. At Shandong Longhai, we address these concerns through:

5. After-Sales Support
We provide continuing technical consultation and assistance with customs clearance documentation.
The Evolution of Lubricant Standards, Base Stocks, and Carbon-Reduction Frameworks
The global automotive sector continues to optimize efficiency to meet strict emissions regulations. In light-duty gasoline passenger vehicles, this has driven a transition from traditional higher-viscosity grades (like 10W-40 and 5W-40) to ultra-low viscosity fluids (such as 0W-20, 0W-16, and 0W-12). Lowering the fluid's viscosity reduces internal shear losses and friction inside the engine, helping to lower fuel consumption. These thinner formulations require high-quality Group III+ and Group IV (PAO) base oils to maintain oil film thickness under high temperatures and shear loads.
Modern engines with Turbocharged Gasoline Direct Injection (TGDI) are susceptible to Low-Speed Pre-Ignition (LSPI), an abnormal combustion event that can cause severe engine damage. The API SP and ILSAC GF-6 standards require motor oils to provide effective protection against LSPI and prevent timing chain wear. Shandong Longhai's formulations are designed to meet these specifications, providing reliable protection for turbocharged gasoline engines.
Sustainability is an increasing priority for global industrial procurement. The industry is moving toward formulations that incorporate bio-based synthetic esters and re-refined base oils to lower the carbon footprint of production. We are actively researching eco-friendly base stocks and biodegradable additive packages to support global carbon reduction goals.
Expert Clarifications on Oil Quality, Custom Blends, and Wholesale Logistics
API SP was introduced by the American Petroleum Institute to improve upon SN standards. It provides enhanced protection against Low-Speed Pre-Ignition (LSPI) in gasoline direct-injection turbocharged engines, reduces timing chain wear, improves oxidation stability, and offers better deposit protection.
We formulate using Group I, II, III, and IV (PAO) base oils. The choice of base stock depends on the target performance class, viscosity grade, and the application's thermal requirements. High-performance synthetic products utilize Group III and PAO stocks to maximize shear stability and chemical resistance.
Our automated bottling lines utilize metering flow control systems. This technology ensures high dosing accuracy, keeping volume variation within 1‰ to 2‰. This precision prevents package overfilling and ensures consistent volume across production runs.
Yes. Through our OEM/ODM service, we support custom bottle design, label printing, carton packaging, and customized brand detailing. We work with clients to develop packaging that meets local regulatory requirements and retail specifications.
We operate in compliance with ISO 9001 quality management standards. Every production run undergoes laboratory analysis to verify key properties, including kinematic viscosity, viscosity index, density, flash point, and moisture content. Retained samples are kept for quality tracking.
Lead times depend on the order volume, package sizes, and customization requirements. Standard bulk shipments of stock products typically ship within 15 to 20 days. Custom OEM orders requiring packaging fabrication generally ship within 30 to 45 days after design approval.
