Explore our internationally certified range of industrial, heavy-duty, and high-performance automotive and motorcycle formulations.
Established in 2009 and headquartered in the highly industrialized city of Zibo, Shandong, Shandong Longhai Lubrication Technology Development Co., Ltd. stands as a premier high-tech enterprise integrating research, engineering development, automated manufacturing, and global export infrastructure. For over 15 years, we have specialized in high-performance tribological systems and specialized chemical applications, building a fully integrated value chain to deliver superior industrial and automotive lubrication solutions.
Our proprietary brand portfolio includes "Century Longhai" alongside our strategic international cooperation brand, the British "A Ba" series. Our comprehensive product assortment satisfies strict API, ACEA, and JASO standards. From advanced synthetic motorbike engine oils, multi-grade gasoline and diesel engine oils, to heavy-duty gear fluids, anti-wear hydraulic solutions, and high-performance agricultural or engineering machinery oils, we operate with a singular goal: maximizing equipment reliability while reducing total operating costs.
To assure absolute commercial trust, all products within our supply portfolio are backed by comprehensive liability insurance via PICC (People’s Insurance Company of China), securing our partners' long-term brand equity in highly competitive global territories.
Evaluating the convergence of high-power-density engine architecture, localized environmental demands, and next-generation additives.
Motorcycle engines run at significantly higher RPMs (up to 15,000 RPM in racing segments) and operate at higher temperatures than typical passenger cars. This environment subjects the oil film to immense mechanical shear. Our formulations utilize advanced shear-stable Viscosity Index Improvers (VIIs) to guarantee consistent hydrodynamic lubrication and maintain critical film thickness under severe boundary friction conditions.
Unlike standard automotive engines, the majority of four-stroke motorcycles utilize a shared sump where the same lubricant operates across the engine, transmission, and wet clutch system. Inadequate friction levels can cause clutch slippage, whereas excessive friction leads to rough gear shifts and rapid wear. We balance base oils and friction modifiers to align strictly with the JASO T 903:2016 MA2 and MB parameters.
With environmental regulations like Euro 5, India's BSVI, and China VI coming into effect, OEMs require lubricants with lower Sulfated Ash, Phosphorus, and Sulfur (SAPS) content. This protects exhaust after-treatment devices, such as three-way catalytic converters, without degrading basic engine protection profiles. Our synthetic chemical formulas prevent catalyst poisoning and prolong component life.
How our customized chemical engineering meets different regional environments, operating loads, and fuel parameters.
In tropical urban centers throughout Southeast Asia and Latin America, motorcycles operate under heavy cargo loads in prolonged stop-and-go traffic. These severe conditions lead to rapid fuel dilution, accelerated oxidation, and deposit formation. Our tailored formulations integrate robust salicylate-based detergent packages and high-performance anti-oxidants. This prevents ring-sticking, keeps the pistons clean, and controls oil consumption even when running on local fuels with varying sulfur levels.
For modern touring, off-road, and high-performance racing platforms, the priority is minimizing internal friction to maximize power output while ensuring component protection. Our fully synthetic range, formulated with premium polyalphaolefins (PAO) and ester base oils, reduces traction coefficients and delivers exceptional shear stability. This guarantees optimal performance across cold starts up to maximum operating temperatures.
The rise of global e-commerce has placed immense stress on commercial delivery fleets. Delivery bikes face constant cold starts, idling, and short-distance operations. This driving style promotes moisture condensation and acid formation in the crankcase, causing engine wear. Longhai’s synthetic motorbike engine oils are designed with advanced corrosion inhibitors and TBN (Total Base Number) retention additives. This neutralizes acidic combustion byproducts, extending drain intervals and keeping fleet maintenance costs low.
Validated by global certifications and running on fully automated, precision-metered production lines.
Longhai Lubrication Technology treats product quality as our core priority. We operate under three major management systems: ISO 9001:2015 (Quality Management), ISO 14001:2015 (Environmental Management), and ISO 45001:2018 (Occupational Health and Safety). Additionally, our automatic transmission fluids hold official Mercedes-Benz approvals, reflecting our commitment to meeting strict global OEM specifications.
Our blending plant features automated filling lines equipped with advanced flowmeters, guaranteeing a high filling accuracy within 1‰ to 2‰. This advanced manufacturing framework has boosted overall filling speed by 20% to 35%. This efficiency ensures quick delivery times for large-scale global orders, maintaining high quality and consistency across every batch.
We invest over 5% of our annual revenue into R&D, collaborating with leading universities and research institutes to continually advance our tribological formulations. Our laboratory is equipped with precision testing systems (including gas chromatography, ICP spectrometers, and high-temperature high-shear viscometers) to verify that every batch meets the required specifications before leaving the factory.
A structured, efficient process path to bring customized lubricants to international markets.
Evaluating target markets, climate conditions, OEM specifications, and packaging preferences.
Optimizing base oil blends and additive chemistry to meet JASO/API targets.
