Explore our core selection of high-performance motor oils, diesel fluids, and hydraulic formulas tailored for global distribution.
Established in 2009 and headquartered in the industrial heartland of Zibo, Shandong, Shandong Longhai Lubrication Technology Development Co., Ltd. is a high-tech pioneer integrating R&D, advanced blending processes, and global wholesale supply systems. For over 15 years, we have built a highly integrated manufacturing matrix dedicated to engineering high-performance lubricants that meet the demands of modern transportation and industrial machinery.
Under our domestic signature brand "Century Longhai" and our international strategic brand, the British "A Ba" series, we design engine oils that provide maximum wear protection, exceptional shear stability, and optimal fuel efficiency. Our product portfolio spans API-compliant gasoline engine oils, high-load diesel lubricants, advanced transmission fluids, anti-wear hydraulic oils, and eco-friendly automotive solutions like premium urea and antifreeze formulations. Our quality assurance is backed by PICC (People's Insurance Company of China), providing an extra layer of commercial protection to our distributors and B2B partners worldwide.
An in-depth look at how low-viscosity demands and emissions regulations are reshaping global supply chains.
The global automotive lubricant landscape is undergoing a massive regulatory and technological shift. Major automotive markets in North America, Europe, and Asia-Pacific are enforcing stricter carbon neutrality goals and fuel economy metrics. This has created a direct global demand for next-generation gasoline engine oils, specifically falling into low-viscosity classifications like 0W-16, 0W-20, and 5W-30. Modern turbocharged gasoline direct-injection (TGDI) engines demand motor oils that can prevent Low-Speed Pre-Ignition (LSPI) while simultaneously offering exceptional protection against timing chain wear and deposit formation.
"Meeting the modern API SP and ILSAC GF-6 standards is no longer optional for international importers. It is the fundamental baseline to protect high-compression, downsizing engines from LSPI-induced catastrophic failures while supporting fleet-wide carbon footprint reductions."
For wholesale importers and distributors, sourcing from a manufacturer capable of formulating consistent, high-performance base stocks (Group III hydrocracked and Group IV PAO synthetics) combined with advanced additive chemistry is essential. Shandong Longhai Lubrication Technology bridges this gap, providing large-scale batch uniformity that helps B2B buyers maintain stable retail and commercial operations in highly competitive markets.
Driving lubrication performance forward through advanced chemical engineering, synthetic base stocks, and eco-friendly additive packages.
By blending high-purity Group III synthetic base oils with advanced shear-stable viscosity index improvers (VII), our lubricants maintain optimal HTHS (High-Temperature High-Shear) levels. This provides reliable oil film strength at engine operating temperatures exceeding 150°C, drastically reducing turbocharger deposits and piston ring wear.
Our API SP and SN Plus formulas utilize balanced detergent chemistry. By reducing calcium-based additives and introducing magnesium-based detergents, we effectively eliminate the risk of LSPI in modern GDI/TGDI engines. This preserves piston crowns and cylinder walls, extending engine operational life.
With the rise of PHEVs and HEVs, engines experience frequent stop-start cycles and lower run-temperatures, increasing water condensation risk. Longhai's upcoming formulation pipeline optimizes emulsion control and corrosion protection to shield hybrid engines during cold-start phases.
Adaptable performance formulated specifically for diverse global climates and driving conditions.
Recommended Viscosity: 0W-20 / 0W-30
For regions like Northern Europe, Canada, and Northern China, our fully synthetic lubricants are engineered with low pour points (down to -45°C). This allows rapid oil circulation to critical engine components within milliseconds of startup, significantly preventing dry-friction wear.
Recommended Viscosity: 10W-40 / 20W-50
In hot desert climates such as the Middle East and parts of Africa, oil oxidation and thermal thinning are key issues. Our high-viscosity formulations prevent oil degradation, minimize evaporation loss (NOACK volatility), and maintain constant cylinder pressure under high engine load.
Recommended Viscosity: 5W-30
Taxi services, logistics fleets, and urban rideshare vehicles suffer from fuel dilution and soot buildup. Our high-performance additive package contains dispersants that prevent sludge accumulation, keeping vital engine passages clean during high-traffic operations.
Shandong Longhai's production infrastructure is designed to handle large-scale global demands without compromising precision. Spanning 131 acres, our Zibo manufacturing base is equipped with fully automated blending and packaging systems, yielding an annual capacity of 200,000 tons of finished lubricants.
We utilize precision metering filling machinery, ensuring a filling accuracy of 1‰ to 2‰. This system increases packaging line speeds by 20% to 35%, ensuring rapid fulfillment of bulk wholesale orders. By maintaining direct, long-term contracts with global base oil refineries and chemical additive manufacturers, we stabilize raw material supply, offering our B2B partners consistent pricing even amidst global market fluctuations.

Our formulations cover a wide range of API standards, from heritage classes like API SJ, SL, and SM to modern options like API SN, SN Plus, and API SP. We also offer formulations that meet ILSAC GF-6 standards, designed for optimal fuel efficiency and LSPI prevention in modern turbocharged direct-injection (TGDI) engines.
Yes. Our laboratory can adjust chemical compositions to optimize properties such as pour points and viscosity indexes. We formulate 0W-16/0W-20/0W-30 grades with low pour points (down to -45°C) for colder regions, and robust 10W-40/20W-50 grades for hotter climates.
For standard packaging and established formulas, production and packaging typically take 15 to 25 days. Custom bottle shape design, label branding, and custom formulation testing may extend the initial lead time by 10 to 15 days.
Our production facilities utilize automated blending systems with precise mass flow meters to ensure consistent raw material ratios. Each production batch undergoes testing for key parameters, including Kinematic Viscosity (at 40°C and 100°C), Viscosity Index, Flash Point, CCS, and Total Base Number (TBN) before packaging and shipping.
