Engineered to exceed international standards, providing unmatched protection under extreme mechanical load and high thermal stress.
Motorcycle engines present a significantly harsher operating environment than passenger car engines. Operating at speeds up to 15,000 RPM—more than double the limit of typical automotive engines—motorbike drivetrains experience exceptional thermal loading and shear stress. Furthermore, the vast majority of motorbikes utilize a unified sump system in which a single fluid must simultaneously lubricate the engine, the wet clutch, and the gearbox. This multidimensional demand requires specialized additive chemistry that goes beyond standard API passenger car motor oil (PCMO) standards.
In wet clutch systems, the coefficient of friction must be carefully managed. If the lubricant contains excessive friction modifiers (such as those found in resource-conserving automotive oils), the clutch plates will slip, leading to power loss, accelerated wear, and system failure. Conversely, if the fluid is too viscous or lacks anti-wear chemistry, the high-load gears inside the transmission will suffer from pitting and micro-scuffing. Achieving this balance is the primary goal of the JASO T 903 standard, which divides motorcycle oils into JASO MA (MA1 and MA2) for wet clutches and JASO MB for dry clutches.
"Unlike passenger vehicle lubricants that prioritize friction reduction to optimize fuel economy, high-performance motorbike lubricants require balanced frictional properties. Our formulations ensure optimal clutch grip alongside robust anti-wear protection for the gear teeth."
The global demand for high-quality motorcycle lubricants is shifting toward fully synthetic formulations (PAO and Ester-based). B2B procurement professionals, fleet operators, and distributors are increasingly prioritizing long-term equipment protection and extended oil drain intervals (ODI) over low-cost mineral alternatives. Key drivers include:
Shandong Longhai Lubrication Technology Development Co., Ltd. leads the market through intensive R&D and advanced manufacturing capabilities.
Established in 2009 in Zibo, Shandong, Shandong Longhai Lubrication Technology Development Co., Ltd. has developed into a high-tech enterprise integrating R&D, production, and sales. With over 15 years of industry experience, we offer a complete supply chain for global industrial and transport markets. We manufacture under our proprietary brand "Century Longhai" alongside the international strategic brand British "A Ba", with all products backed by PICC quality insurance.
Our facility features automated blending plants and metering filling lines that ensure filling accuracy within 1‰ to 2‰. By upgrading to these systems, we have improved filling efficiency by 20% to 35%, ensuring reliable production and prompt delivery for high-volume wholesale contracts globally.
A look at how we integrate technical advances to support commercial, industrial, and fleet applications.
Utilizing high-performance anti-wear systems, including Zinc Dialkyldithiophosphate (ZDDP), we form a resilient tribofilm on metal surfaces. This prevents direct metal-to-metal contact under high shear forces, extending the lifespan of critical components.
Formulated with Group III base oils and synthetic esters, our lubricants resist thermal breakdown and oxidation, reducing sludge build-up and carbon deposits on pistons, even when operating at temperatures exceeding 250°C.
Engineered to meet JASO MA2 specifications, our motorcycle oils provide the friction level required to prevent clutch slippage, ensuring smooth gear engagement and efficient power transfer.
As the transportation sector evolves, our research is focused on three primary lubrication technologies:
Developing biodegradable synthetic formulations derived from renewable resources to meet rising environmental regulations without sacrificing engine protection.
Incorporating nano-spheres (such as graphene and silica derivatives) that act as micro-ball bearings within the friction zones, reducing fuel consumption and friction losses.
Formulating dielectric cooling oils designed for electric motor cooling and high-speed reduction gears in next-generation electric powertrains.
From custom formulation to packaging design, we provide integrated services backed by international certifications.
Longhai Technology has passed ISO 9001:2015 quality management system certification, ISO 14001 environmental management system certification, and OHSAS 18001 occupational health management certification. We have also earned automatic transmission approvals from Mercedes-Benz, reflecting the stability of our products and manufacturing processes. We use precise testing technologies to ensure performance under extreme operating conditions, helping clients lower maintenance costs.
We tailor viscosity grades, synthetic percentages, and additive levels to target specific market preferences and climate conditions.
We offer container sizes ranging from 1L bottles to 1000L IBC tanks, complete with custom label design and branding solutions.
We handle international export requirements, providing GHS-compliant Safety Data Sheets (SDS) and customs clearance support.
Our systematic OEM/ODM partnership process is structured to guarantee quality and regulatory compliance:

Understanding oil specifications is essential for proper fleet management and retail distribution. Our product line supports API and JASO specifications to ensure compatibility across applications:
We source raw materials directly from leading global base oil suppliers, choosing Group II, Group III, and synthetic esters depending on the product grade. This base oil quality is matched with balanced additive chemistry to maintain viscosity stability, even when subjected to high engine shear forces.
Technical answers to key inquiries from procurement managers, distributors, and engineers.
No, using PCMO in wet-clutch motorcycle engines is not recommended. Passenger car oils are formulated with friction modifiers to reduce mechanical drag and improve fuel economy. In a motorcycle, these additives can coat the wet clutch plates, causing slippage, power loss, and accelerated wear. Motorcycle-specific lubricants must comply with JASO MA/MA2 standards to ensure the correct level of friction for proper clutch engagement.
JASO MA specifies the friction performance required for wet clutches. JASO MA1 represents the lower friction range within this standard, while JASO MA2 represents the higher friction range. MA2 oils provide the strongest grip, making them ideal for high-torque, high-performance sports bikes. If an engine manual requires JASO MA, either MA1 or MA2 fluids can be used, but MA2 is generally preferred for performance applications.
Our factory operates under ISO 9001:2015 quality management procedures. We use automated batching and blending equipment with mass flow meters to ensure mixing precision. Every batch is tested in our laboratory to verify kinematic viscosity, viscosity index, flash point, pour point, and water content before packaging and shipment.
Yes. Our R&D team can develop custom formulations based on regional requirements. For cold regions, we optimize cold-cranking viscosity (CCS) and pour points. For hot, tropical climates, we formulate with high-stability base oils to maintain viscosity and film strength under high operating temperatures.
When stored in original, unopened containers in a dry environment between 5°C and 40°C, our lubricants remain stable for up to 5 years. Once a container is opened, it should be kept sealed and used within one year to minimize exposure to atmospheric moisture and oxidation.
Engineered for demanding industrial, automotive, and fleet maintenance programs.
