Engineered for extreme workloads, high thermal stability, and maximum engine longevity.
Whitepaper on Tribological Engineering, Modern Engine Optimization, and Supply Chain Integration
The global motorcycle industry is witnessing an unprecedented transition from standard mineral-based oils to high-performance fully synthetic formulations. Modern engines operating under the rules of strict emissions limits (such as Euro 5 and Bharat Stage VI) generate immense thermal loads. Unlike passenger car engines, motorcycle engines typically feature integrated transmission designs, meaning the same engine oil must lubricate the engine components, protect the transmission gears, and maintain precise wet clutch engagement.
Due to this combined functional demand, standard automotive engine oils fail to prevent clutch slippage or dynamic shear stresses. Moto synthetic oils are formulated with Group III hydrocracked, Group IV Polyalphaolefin (PAO), or Group V Esters to deliver superior shear stability, high viscosity index, and optimized friction co-efficients in compliance with standards like JASO T 903:2016 (MA/MA2 for wet clutches and MB for dry clutches).
Established in 2009 and headquartered in Zibo, Shandong Province, China, Shandong Longhai Lubrication Technology Development Co., Ltd. is a premier high-tech enterprise dedicated to the R&D, blending, packaging, and international export of high-grade lubricants. For over 15 years, our brand has stood at the intersection of material science and manufacturing efficiency.
We boast a comprehensive industrial chain structure, manufacturing and marketing our proprietary brand "Century Longhai" alongside our strategically integrated international line, the British "A Ba" series. Our comprehensive product catalog addresses the diversified requirements of both commercial transportation and industrial equipment: from diesel and gasoline engine oils, gear oils, hydraulic transmission fluids, and engineering machinery lubes, to specialized four-stroke motorcycle lubricants, automotive urea solutions, antifreeze, and high-performance industrial gear oils. Demonstrating our reliability and dedication to quality assurance, all products are insured by PICC (People's Insurance Company of China).
Operating within China's largest chemical clusters allows Shandong Longhai to achieve unrivaled supply chain efficiency. Our state-of-the-art production lines are equipped with automatic batch blending and metering filling technologies that guarantee consistent batch-to-batch quality.
To support global distribution and ensure regulatory compliance, Shandong Longhai adheres to international quality structures. Our facilities are certified under:
Understanding that one size does not fit all, Shandong Longhai specializes in customized formulation design. Whether you require a high-viscosity index synthetic oil for hyper-sport motorcycles operating in desert climates, or low-friction fuel-saving oils for urban delivery fleets, our research team can engineer specialized formulations matching target API, ACEA, and JASO ratings.

Synthetic motorcycle oils are formulated using pure synthesized chemical compounds (Group III, IV/PAO, V Ester). They contain fewer impurities than mineral oils, exhibiting superior shear stability, lower volatility, higher heat resistance, and better fluid dynamics at extreme sub-zero temperatures. This is vital for high-RPM motorcycle engines that run significantly hotter than cars.
Most 4-stroke motorcycles use a wet clutch system where the engine, transmission, and clutch share the same lubricant. Passenger car oils contain friction reducers that cause motorcycle wet clutches to slip. JASO MA and MA2 oils are engineered with balanced friction coefficients to prevent slippage while protecting the gears and pistons.
Our facility is ISO 9001 and ISO 14001 certified. We utilize automated blending software to measure base oils and additives accurately. Furthermore, every production batch is thoroughly inspected in our precision laboratory. Samples of each batch are kept for 24 months for traceability.
Minimum Order Quantities (MOQs) depend on the container size (e.g., 1L, 4L, 18L pails, or 200L drums) and formula complexity. Typically, a standard custom batch order ranges from 5 to 10 metric tons. Lead times usually run between 15 to 30 days after label art approval, depending on packaging material availability.
