Explore our world-class fully synthetic motor oils and heavy-duty industrial application fluids engineered for maximum efficiency, thermal stability, and wear protection.
The global motorcycle industry is undergoing an unprecedented technological transition. Modern engine architectures demand lubricants that can withstand extreme mechanical shear, elevated thermal loading, and rigorous emissions controls (such as Euro 5 and BS VI standards). As standard mineral-based lubricants reach their physical limitations, fully synthetic motor formulations have emerged as the definitive solution for maximizing power output and ensuring mechanical longevity.
As a premier Moto Synthetic Oil Factory, Shandong Longhai Lubrication Technology Development Co., Ltd. has stood at the forefront of this industrial revolution since 2009. By integrating advanced Ester and Polyalphaolefin (PAO) chemistry with state-of-the-art additive packages, we provide global B2B procurement partners, distributors, and bulk buyers with high-performance solutions engineered to meet the stringent demands of high-revving four-stroke (4T) motorcycle engines, passenger vehicles, and heavy-duty industrial machineries.
The commercial demand for synthetic engine lubricants spans across every continent, driven by distinct automotive and industrial parameters. In regions like Southeast Asia and South America, the dominance of two-wheeled transport calls for specialized, cost-effective, yet exceptionally durable 4T motorcycle lubricants. Conversely, European and North American markets place immense weight on ultra-low viscosity ratings (e.g., 0W-20, 5W-30) that reduce internal friction to meet strict fuel economy targets.
Furthermore, commercial fleet operators and heavy industrial operations are shifting away from frequent maintenance intervals. By utilizing advanced fully synthetic base oils (API Group III, IV, and V), operators can achieve extended drain intervals, reduce downtime, and cut overall carbon emissions. A certified Moto Synthetic Oil supplier must therefore possess the capability to customize formulations dynamically based on localized climates, fuel grades, and regional mechanical emissions compliance.
As one of the world's primary chemical and manufacturing hubs, China offers exceptional infrastructural advantages that make high-volume lubricant sourcing highly efficient and cost-effective. Shandong Longhai's facility, located in the prominent industrial hub of Zibo, Shandong, spans over 131 acres. This strategic proximity to base chemical suppliers allows us to significantly reduce shipping overheads on raw materials, translating directly into competitive pricing structures for our international distributors.
Our factory incorporates fully automated blending software and high-speed metering filling lines. This design not only ensures a filling accuracy margin of 1‰-2‰ but also boosts output speed by 20% to 35% compared to semi-automated counterparts. Through vertical integration, robust quality testing labs, and strict quality assurance under PICC (People's Insurance Company of China), we ensure that high volumes do not compromise the rigorous standards expected by global supply chains.
Shandong Longhai's manufacturing facilities are engineered for ultimate reliability. Every batch undergoes strict gas chromatography and viscosity index checking inside our certified labs. By utilizing automatic metering valves, we eliminate human error during the critical chemical additive injection stages.
This high-tech infrastructure allows us to easily execute complex OEM contract manufacturing agreements for diverse lubricant grades, ranging from heavy-duty diesel oils (CK-4/CJ-4) to professional-grade turbine and gear oils.
Different machinery and driving environments call for specialized lubricants. Below, we break down how our targeted products perform in specific real-world environments:
Motorcycles operate at much higher RPMs and temperatures than passenger cars. Our special 4-Stroke Motorcycle oil features JASO MA2 performance levels to prevent wet-clutch slippage while offering maximum gear protection in the shared sump.
For city buses, utility trucks, and mining equipment, our API CK-4 and CJ-4 synthetic diesel oils provide extreme wear protection under high soot levels and heavy payloads, keeping fleets moving longer.
From high-temperature turbine plants to extreme-pressure worm gear systems, our industrial gear lubricants (L-CKC/L-CKD) maintain dynamic oil films to prevent micro-pitting under high shock loads.
The future of tribology—the study of friction, wear, and lubrication—is closely linked with digital integration and environmental responsibility. Synthetic base formulations are evolving to incorporate bio-derived synthetic esters, which decompose cleanly without leaving toxic deposits in aquatic ecosystems.
Furthermore, Shandong Longhai is actively researching AI-driven molecular modelling to simulate the interactions of shear-stable polymer viscosity modifiers under extreme heat. By simulating these molecular structures digitally, we can rapidly prototype customized lubricants, cutting down formulation development times and allowing global partners to quickly launch tailored products designed for local markets.
A reliable supply chain is essential for international distributors. We offer structured, transparent contract manufacturing services (OEM/ODM) that guide our clients from initial concept to bulk shipment delivery.

Our factory strictly follows international quality standards to ensure performance and consistency. Shandong Longhai has successfully earned ISO-9001-2015 Quality Management certification, ISO-14001 Environmental Management certification, and ISO-18001 Occupational Health and Safety certification. Our transmission fluids have also achieved official Mercedes-Benz certification, providing a solid foundation of trust for distributors and commercial clients worldwide.






Unlike passenger car engines, 4-stroke motorcycle engines share a single oil sump that lubricates the engine, gearbox, and wet clutch. Consequently, motorcycle oil must have a high coefficient of friction to satisfy JASO MA2 specifications, preventing wet clutch slippage under high loads. Passenger car oils, conversely, contain friction-reducing modifiers that can cause motorcycle clutches to slip and wear prematurely.
Manual blending introduces measuring variations that can alter additive levels. Our automated metering system measures and controls additive injections to an accuracy of 1‰-2‰. This ensures that every production batch meets identical viscosity, pour point, and shear-stability metrics, maintaining consistency across large-scale export orders.
Zibo is a highly developed industrial and petrochemical hub in Shandong Province. This provides us with direct access to base oil feedstocks and additive packages. Furthermore, our close proximity to Qingdao Port allows for streamlined maritime shipping, reducing transit times and freight costs for global buyers.
Yes. Our in-house research laboratory invests more than 5% of our annual revenue into design and testing. We can modify the base oil blend and polymer additive ratios to formulate lubricants that flow smoothly at -40°C or maintain stable oil films in desert environments reaching 50°C.
We offer flexible manufacturing services to support both initial trial batches and high-volume runs. Customization options include bottle design, label printing, box design, and custom viscosity grades. Contact our sales team with your target market specifications to receive a customized quote.
