Engineered to deliver ultimate structural protection, superior shear stability, and maximized thermal management performance under extreme operating conditions.
An in-depth analysis of tribological demands, commercial supply chain vectors, and critical quality parameters driving internal combustion efficiency globally.
The global motorcycle market is witnessing a major transformation. Rapid urbanization in Southeast Asia, Latin America, and Africa, combined with the booming e-commerce and last-mile delivery sectors, has significantly increased the demand for high-durability lubricants. Unlike automotive engines, two-wheeler systems share a unified sump where the engine, wet clutch, and transmission gears are lubricated by a single fluid. This unique setup requires lubricants that offer both high traction coefficients for wet clutches and excellent extreme-pressure shear stability for gears.
Global procurement teams now focus heavily on fluid stability under sustained high thermal stress. Commercial motorcycle fleets, operating under continuous start-stop conditions in highly congested cities, subject lubricants to extreme degradation. As a result, sourcing partners are shifting away from mineral oils toward group II hydro-processed and Group III synthetic formulations to achieve longer drain intervals and lower maintenance costs.
"The core challenge in modern motorcycle lubrication is balancing friction requirements. A lubricant must provide low friction in the cylinder to maximize fuel efficiency, yet maintain high static and dynamic friction coefficients in the clutch to prevent slippage. Our formulations address this trade-off using advanced polymer engineering."
Furthermore, stringent emissions standards (such as Euro 5 and BS-VI) require lubricants with lower sulfated ash, phosphorus, and sulfur (SAPS) limits. This keeps catalytic converters working efficiently without compromising the anti-wear protection that valve-train assemblies need. In this demanding landscape, only manufacturers with advanced R&D capabilities can supply products that consistently meet these requirements.

Founded in 2009 and headquartered in Zibo, Shandong, Shandong Longhai Lubrication Technology Development Co., Ltd. is a high-tech enterprise integrating research and development, production, and sales. With over 15 years of deep involvement in the lubricant industry, we have built a complete, vertically integrated industrial chain system dedicated to providing high-performance lubrication solutions for the global industrial and transport fields.
Longhai Technology operates its proprietary brand "Century Longhai" alongside our international strategic partnership brand, the British "A Ba" series. Our comprehensive product catalog covers diesel engine oil, gasoline engine oil, gear oil, hydraulic transmission oil, anti-wear hydraulic oil, specialized engine oil for engineering machinery, special natural gas engine oil, fully synthetic formulations, automotive urea solution, antifreeze, special motorcycle engine lubricants, industrial oil, and automatic transmission fluids.
To ensure maximum security and reliability for our global partners, the entire product portfolio is insured by the People's Insurance Company of China (PICC), backed by comprehensive product liability and quality insurance guarantees.
Leveraging economies of scale, highly automated blending processes, and precision analytical labs in Zibo, Shandong.
Our production plant spans 131 acres and features high-efficiency automatic blending and filling equipment. The volumetric metering filling mechanism guarantees an accuracy range within 1‰ to 2‰. By upgrading to smart packaging workflows, we increased filling speeds by 20% to 35%, ensuring rapid order turnaround.
Longhai Technology invests over 5% of its annual revenue into research and development. In collaboration with leading universities and research institutes, we continuously refine our lubricant formulations to match real-world field trials and demanding international standards.
Our precision laboratory is equipped with advanced testing systems like ASTM-compliant viscometers, gas chromatographs, and ICP spectrometers. Every batch of base oils and additives undergoes rigorous testing before blending to guarantee consistent viscosity index, TBN, and shear stability.
Customized lubrication engineering designed for regional climates, operating environments, and diverse engine demands.
In traffic-heavy metropolitan areas across Latin America and Southeast Asia, courier and delivery motorcycles operate under severe conditions. Frequent stop-and-go driving prevents the engine from reaching its optimal operating temperature. This leads to fuel dilution, sludge formation, and rapid additive depletion. Our custom 10W-30 and 10W-40 JASO MA2 synthetic oils use highly active dispersants and detergents to suspend soot particles, keeping engine components clean and preventing piston deposits.
For operations in desert regions, dust contamination and extreme heat (exceeding 45°C) pose major threats to engine life. High temperatures accelerate oil oxidation and viscosity loss, which can lead to oil film rupture. Our specialized formulations feature high-viscosity-index Group III synthetic base stocks and robust anti-wear additives (ZDDP). This creates a strong protective barrier over gears and cams, even under extreme thermal stress.
In rural and agricultural regions where utility motorcycles carry heavy loads on unpaved roads, engines run at low speeds but experience high load factors. This operates the engine under boundary lubrication conditions. To prevent piston ring and cylinder liner wear, we fortify our lubricants with specialized extreme-pressure additives. These additives chemically bond to metal surfaces, preventing direct contact and wear.
Performance superbikes require lubricants that maintain viscosity at extremely high engine speeds (often exceeding 12,000 RPM) and shear rates. Our fully synthetic PAO/Ester-based formulations offer outstanding shear stability. They resist mechanical degradation in the gearbox while minimizing internal friction to unlock maximum engine horsepower.
Analyzing technology shifts, environmental regulations, and next-generation fluid engineering over the next decade.
To reduce carbon footprints, the industry is transitioning from traditional 20W-50 grades toward thinner oils like 5W-30 or 10W-30. Achieving this reduction in viscosity requires advanced base oils and friction modifiers to maintain critical wear protection while minimizing fluid drag.
As electric two-wheelers gain market share, developers are designing specialized e-fluids. These fluids require precise dielectric properties, copper compatibility, and efficient heat transfer capabilities to cool integrated electric motors and lubricate reduction gearboxes.
Environmental standards are driving demand for biodegradable lubricants. R&D centers are developing formulations that use synthetic esters derived from renewable plant materials. These formulations offer high biodegradability alongside the performance of conventional synthetic oils.

Passenger car motor oils (PCMO) are formulated primarily to reduce friction in the engine block, often containing friction modifiers that can cause wet clutches in motorcycles to slip. Motorcycle engine oils, however, must lubricate the engine, wet clutch, and gearbox simultaneously. They are engineered to comply with JASO MA/MA2 standards to maintain the appropriate friction levels for clutch engagement while providing high shear protection for integrated gears.
JASO MA2 is a sub-classification within the JASO T 903 standard, indicating high friction performance. It specifies strict limits for three frictional properties: Dynamic Friction Index (DFI), Static Friction Index (SFI), and Stop Time Index (STI). This ensures reliable clutch engagement and prevents slippage under high torque loads, particularly in modern sport bikes and heavy-duty delivery vehicles.
In motorcycle sumps, the engine oil is subject to severe mechanical shear forces from the transmission gears. These forces can break down polymer viscosity index improvers (VII), leading to oil thinning and a loss of wear protection. Our formulations use highly shear-stable polymers to ensure the oil maintains its target viscosity throughout the drain interval.
We utilize automated blending systems with mass-flow metering to keep filling deviations within 1‰ to 2‰. Every production run is tested in our quality control laboratory for viscosity at 40°C and 100°C, viscosity index, flash point, pour point, and total base number (TBN) before packaging.
Yes. Our R&D team regularly customizes formulations based on localized demands. We adjust base oil selections and additive packages to suit hot, humid climates in Southeast Asia, cold regions in Northern Europe, or high-load conditions in developing delivery sectors.
