Engineered to ensure maximum shear stability, clean combustion, and ultimate component life under severe operating pressures.
An in-depth analysis of tribological demands, the energy transition, and base oil chemistry requirements for modern engine systems.
The global motorbike engine oil industry is undergoing a structural transition driven by strict emission standards (such as Euro 5 and Euro 6 guidelines) and the rapid growth of high-output, low-displacement engine designs. Modern two-wheeler engines operate at significantly higher temperatures, speeds, and power densities than passenger cars. This demands lubricants engineered with exceptional thermal oxidation stability, mechanical shear resistance, and specific frictional profiles.
High-tier applications demand premium Group II hydrocracked base oils or Group III/IV synthetic hydrocarbons. These minimize volatility, prevent oil consumption at high engine RPMs, and maintain a robust hydrodynamic lubrication layer between critical engine components.
Motorcycles share one lubricant fluid across the engine, clutch, and gearbox. The oil must balance low friction to prevent power losses with high friction in the clutch zone to prevent slipping. Our formulations strictly adhere to the JASO MA2 and MB friction benchmarks.
Utilizing high-performance Star-Polymer viscosity index improvers (VIIs). Our products resist mechanical shear under extreme gear contact pressures, ensuring stable High-Temperature High-Shear (HTHS) viscosity throughout extended drain periods.
Shandong Longhai Lubrication Technology Development Co., Ltd. was established in 2009 and is headquartered in Zibo, Shandong. As a certified high-tech enterprise, we integrate research and development, smart production, and global export services. For over 15 years, we have served the lubrication sector, building a complete supply chain spanning industrial, automotive, and heavy-duty marine lubricants.
Our domestic brand "Century Longhai" is a mark of reliability, complemented by our strategic international line: the British "A Ba" series of products. To guarantee maximum trust and security, all our products are fully backed and insured by the PICC (People's Insurance Company of China), demonstrating our commitment to quality.
Our production covers diesel engine oils, gasoline engine oils, gear oils, hydraulic transmission fluids, anti-wear hydraulic fluids, specialized machinery oils, natural gas engine oils, fully synthetic lubricants, automotive urea solutions, coolants, and custom 4-stroke motorbike oils.
