High-performance solutions formulated to exceed API, JASO, and ACEA industrial standards globally.
A comprehensive analysis of technological evolution, base oil dynamics, and performance standards.
The global two-wheeler engine oil industry is witnessing a significant shift from traditional high-viscosity oils (e.g., 20W-50) to light-weight, highly stable grades such as 10W-30, 5W-30, and 10W-40. Driven by global emission targets (such as Euro 5, BS VI, and equivalent standards), OEMs are designing tighter-clearance engines that demand thinner oils. These fluids reduce hydrodynamic drag, optimizing fuel efficiency without compromising boundary lubrication integrity.
Unlike passenger car motor oils (PCMO), two-wheeler engine lubricants must cater to the requirements of integrated systems: the engine, the gearbox, and the wet clutch. Under the JASO MA2 and JASO MB specifications, oils must deliver precise friction coefficient ratios to prevent clutch slippage while offering wear protection for high-speed transmission gear sets. Longhai's advanced chemical profiles provide industry-leading static and dynamic friction parameters.
Two-wheeler engines operate at higher rev ranges (often exceeding 10,000 RPM) and higher temperatures per unit displacement compared to automobiles. Synthetic oils based on Group III and Group IV (PAO) base fluids offer superior viscosity index (VI) stability. This minimizes thermal oxidation and deposit formation under high-stress operating states, extending service intervals and protecting cylinder linings.
Established in 2009 and headquartered in Zibo, Shandong, Shandong Longhai Lubrication Technology Development Co., Ltd. is a recognized high-tech enterprise integrating advanced R&D, precision manufacturing, and international distribution of industrial and automotive lubricants. With over 15 years of deep industry expertise, we have developed a complete upstream-to-downstream manufacturing supply chain.
Longhai Technology manages its flagship brand "Century Longhai" alongside the strategically aligned British "A Ba" series. The quality of our product portfolio is fully insured by PICC (China People's Insurance Company), giving our global supply network complete peace of mind.
Our commitment to quality control is validated by our certifications, including ISO-9001-2015 Quality Management, ISO-14001 Environmental Management, and ISO-18001 Occupational Health and Safety systems. Notably, our automatic transmission lubricants carry official Mercedes-Benz certification, solidifying our engineering capability to meet strict OEM guidelines.
Supporting high-volume distributors with robust industrial capacities and reliable supply chain security.
Our blending facilities feature modern automation that monitors and controls every parameter. By adopting weight-based and volumetric metering systems, we guarantee high-precision accuracy within 1‰ to 2‰. Our fully automated filling lines increase efficiency by 20% to 35% compared to conventional systems, enabling rapid production turnaround and punctual shipment schedules.
For two-wheeler engine oils, we use Shear Stability Index (SSI) polymers. This technology ensures that viscosity modifiers resist mechanical degradation within the transmission gears, maintaining high film thickness (HTHS viscosity) under extreme temperatures.
Each batch undergoes rigorous laboratory evaluation, including Inductively Coupled Plasma (ICP) emission spectroscopy for additive verification, Cold Cranking Simulator (CCS) testing, and Noack volatilization analysis to ensure compliance with API and JASO specifications.
Developing custom formulations matched to target market climates, performance requirements, and regulatory standards.
Formulating fully synthetic, semi-synthetic, and premium mineral oils that align with API SP/SN/SM/SL/SJ and JASO MA2/MB specifications.
Packaging options ranging from retail-ready 800ml and 1L bottles to 4L canisters, 18L pails, and bulk 200L drums, detailed to your distribution network.
Full documentation services including MSDS, COA, and customs compliance support for hassle-free import in the Americas, Europe, and Asia.
Custom packaging, dynamic label designs, anti-counterfeiting seals, and technical catalogs to strengthen your market presence.
Addressing supply chain hurdles, environmental initiatives, and region-specific regulatory frameworks.
We supply complete compliance certification profiles, supporting local regulations like REACH (Europe), EPA guidelines (North America), and regional quality approvals. Every export cargo leaves our facility accompanied by certificate analyses ensuring frictionless border clearance.
Our research and development initiatives address modern environmental directives. By engineering biodegradable additives and optimizing low-volatility base formulations, we help mitigate particulate emissions, decrease oil consumption, and lower the overall carbon footprint of fleet operations.

Adapting lubrication technologies for next-generation propulsion systems, high-displacement multi-valve engines, and electric hybrid drivetrains.
As the light transportation sector transitions toward electric powertrains, two-wheeler e-motors require specialized cooling fluids. These e-fluids must combine electric insulation with material compatibility and thermal management. Longhai is actively researching low-viscosity dielectric fluids designed for integrated electric drivetrains.
Modern high-displacement engines (twin-cylinder, 4-valve configurations) generate extreme valve-train stress. We use advanced zinc dialkyldithiophosphate (ZDDP) variants combined with friction-reducing organic esters to establish a robust tribofilm, preventing micro-pitting and surface fatigue on cam lobes under extreme pressures.
