High-viscosity index formulations engineered for extreme mechanical shearing, temperature resistance, and clean operation.
Founded in 2009, Shandong Longhai Lubrication Technology Development Co., Ltd. (headquartered in Zibo, Shandong) has established itself as an industry-leading high-tech enterprise integrating R&D, production, and sales. For over 15 years, the company has built a robust industrial chain system, delivering high-performance lubrication technologies customized for the global transportation and industrial manufacturing sectors.
As a highly reliable supplier, Longhai Technology operates its own premium brand "Century Longhai" alongside the international strategic brand British "A Ba" series. Our comprehensive product portfolio spans specialized four-stroke motorcycle oils, gasoline engine oils, heavy-duty diesel engine oils, hydraulic transmission fluids, turbine oils, and automatic transmission fluids. To guarantee maximum reliability for global buyers, all products are covered by quality liability insurance underwritten by PICC (People's Insurance Company of China).
The structural dynamics of two-wheeler engines require advanced fluid engineering to handle higher thermal stress, higher RPMs, and integrated transmission packages.
The global two-wheeler market is undergoing a profound structural evolution. Urbanization across emerging economies in South Asia, Latin America, and Southeast Asia has driven exponential demand for fuel-efficient commuter motorcycles, while developed regions show surging interest in high-displacement leisure and sport bikes. In this macro-environment, engine designs are under constant pressure to deliver greater power density, lower emissions (in compliance with Euro 5 and Euro 6 standards), and extended service lifetimes.
Unlike passenger car engines, which benefit from isolated cooling loops and separate lubricating systems for the engine block and gearbox, typical two-wheeler engines utilize a compact unit construction design. Here, a single lubricant must simultaneously protect the piston/cylinder interface under high temperatures, prevent gear pitting in the transmission, and ensure optimal friction performance for the wet clutch. This triple challenge demands fluids designed with precision balanced friction modifiers, outstanding shear stability, and robust thermal-oxidative control.
To address this complex landscape, Chinese exporters and suppliers have developed integrated component-and-fluid solutions. Shandong Longhai Technology acts as a vital partner in this supply chain, formulating special engine oils that optimize heat dissipation and control oil aeration—vital factors in engines operating regularly between 8,000 and 12,000 RPM. Through systematic tribology R&D, we offer formulations that minimize frictional horsepower losses while preventing clutch slippage under high torque loads.
Sourcing components and fluids from China demands compliance with strict international quality management standards. Shandong Longhai Technology is certified under ISO 9001:2015 for quality management systems, ISO 14001:2015 for environmental management, and ISO 45001:2018 for occupational health and safety. These credentials, along with Mercedes-Benz automatic transmission fluid approvals, demonstrate our commitment to global standard compliance.
In addition to process certifications, global distribution partners benefit from customized localized logistics support. We customize container logistics, packaging specifications, and moisture-barrier protective packaging to ensure that bulk shipments survive maritime transport to hot, humid, or sub-zero climates without degradation or container breathing issues. By offering full OEM/ODM customization alongside third-party quality verification certificates, we minimize the regulatory barriers for global importers.
Optimized lubrication is critical across diverse localized environmental settings and mechanical demands.
Two-wheelers utilized in heavy logistics and last-mile delivery services operate in stop-and-go conditions under high payloads. This driving pattern leads to accelerated lubricant degradation due to fuel dilution and high engine temperatures. Our high-viscosity index formulations maintain a thick lubricating film on cylinder liners, preventing metal-to-metal wear and extending maintenance intervals.
High-performance multi-cylinder motorcycle engines generate extreme shear stress at high RPM levels. Century Longhai's high-performance synthetic motorcycle oils are engineered with shear-stable viscosity index improvers that resist mechanical breakdown, ensuring consistent oil pressure and reliable wet clutch grip under sporty acceleration.
Two-wheelers operating in tropical regions like Southeast Asia or hot arid climates in the Middle East face severe thermal stresses. Without effective heat dissipation, engines run hot, increasing the risk of thermal breakdown and lacquer formation. Our specialized formulations feature high thermal oxidation stability, ensuring clean operation and continuous heat dissipation.
For utility three-wheelers and off-road farming motorcycles, dirt and dust are continuous hazards. High dust ingestion leads to abrasive engine wear. Our high-viscosity index formulations maintain a thick lubricating film, while holding combustion byproducts in suspension to keep the engine clean.
Developing next-generation lubrication technology for cleaner emissions, higher fuel economy, and electric/hybrid drivetrains.
The transition toward cleaner mobility has accelerated the development of new fuel-efficiency lubricants. Traditionally, two-wheeler engines utilized heavy viscosity grades like 20W-50 to protect against mechanical wear under high thermal loads. However, to meet new emission legislation and improve fuel economy, engine manufacturers are shifting toward lower-viscosity grades such as 10W-30 and 5W-30. Longhai Technology is at the forefront of this trend, developing low-viscosity formulations that deliver optimal fuel efficiency without compromising mechanical component protection.
Our long-term technology roadmap focuses on three main developments:
Expanding the use of Group III hydrocracked, Polyalphaolefins (PAO), and synthetic esters to deliver thermal-oxidative stability under extreme operating conditions.
Developing molecular friction modifiers that lower internal fluid friction in the engine while maintaining wet clutch grip (JASO MA2 compliance).
Reducing Sulfated Ash, Phosphorus, and Sulfur (SAPS) levels to protect exhaust catalytic converters and ensure long-term emissions compliance.
Engineering specialized cooling and insulating fluids designed for electric and hybrid two-wheelers, providing copper corrosion protection and thermal control.
Investigating bio-based base stocks to formulate environmentally friendly lubricants that minimize environmental footprint without sacrificing hardware durability.
