Explore our core high-performance formulation spectrum, engineered for extreme thermal stability, anti-wear protection, and advanced fuel economy.
Unlike passenger car engines, motorcycle engines feature integrated transmissions and wet clutches. This unified crankcase configuration requires highly specialized lubricant additive packages that satisfy three crucial criteria: thermal boundary lubrication for high-RPM pistons, gear micro-pitting prevention, and precise friction coefficients to prevent clutch slippage.
Utilizing highly shear-stable radial hydrogenated styrene-diene (HSD) polymers that resist mechanical shearing under high RPMs (up to 15,000 RPM) to sustain critical hydrodynamic lubrication film thickness.
Synergistic blending of Zinc Dialkyldithiophosphate (ZDDP) alongside nitrogen-containing ashless dispersants to cultivate a durable nanometer-scale protective boundary layer on cylinder walls.
Precisely balanced calcium sulfonate detergents and salicylate additives that meet JASO MA2 specification, preventing wet clutch slippage under maximum load acceleration.
Established in 2009 and headquartered in Zibo, Shandong, Shandong Longhai Lubrication Technology Development Co., Ltd. is a premier high-tech enterprise integrating R&D, advanced manufacturing, and global supply chain services. With over 15 years of industry excellence, the company has constructed a resilient vertical manufacturing matrix designed to supply premium lubrication solutions globally.
We take pride in our flagship brand "Century Longhai" alongside our strategic partnership brand, the British "A Ba" series. Our comprehensive product portfolio covers premium diesel engine oil, gasoline engine oil, gear oil, hydraulic transmission oil, anti-wear hydraulic oil, specialized engineering machinery oil, natural gas engine oil, full synthetic motor oil, eco-friendly automotive urea solutions, antifreeze, specialized motorbike oils, and diverse industrial lubricants. Highlighting our dedication to risk management and reliability, all products are fully insured by PICC (People's Insurance Company of China) for quality and liability guarantee.
Motorcycle operating conditions vary widely depending on geography and local habits. Shandong Longhai develops tailor-made additive packages optimized for specific regional stress factors.
Tailored for high-humidity, high-density traffic environments in Thailand, Vietnam, and Indonesia. Our additives prevent fuel dilution and oil film degradation caused by continuous engine idling and thermal stress, keeping air-cooled underbones operating smoothly.
Optimized for temperatures exceeding 45°C. Features enhanced soot dispersion and strong antioxidants that prevent oil thickening and soot agglomeration in extreme dry conditions, protecting off-road dirt bikes and daily delivery fleets.
Formulated for European and American track enthusiasts. High levels of shear-stable polymers and anti-foaming agents ensure zero boundary lubrication failures at high-speed gear transitions and sustained RPM limits exceeding 14,000 RPM.
Shandong Longhai's production infrastructure is located in Zibo, one of China's core chemical clusters. This strategic positioning ensures direct access to premium petrochemical base oils (Group II, III, and IV PAO base oils) and key chemical raw materials, bypassing regional logistical bottlenecks and keeping production costs highly competitive.
By investing over 5% of our annual revenue into the Joint Innovation Center and Precision Testing Laboratories, we continuously optimize our product recipes. Our filling hall features automated metering filling lines that increase filling speed by 20% to 35% compared to conventional processes. This technology assures standard production speed and delivers bulk supplies to clients worldwide without delay.
Whether you require bulk flexitanks, IBC totes, or retail metal cans, our packaging lines scale effortlessly to meet fluctuating seasonal demands, protecting your business from sudden global supply disruptions.
We provide custom chemical formulation, high-precision blending, and specialized packaging designs to elevate your brand reputation in your target markets.
From high-performance fully synthetic racing oils to robust mineral-based lubricants, our lab engineers develop formulas that comply with international standards like API, ACEA, and JASO. By analyzing local ambient temperatures, engine types, and fuel qualities, we design additives that deliver maximum mechanical protection and cost efficiency.
Our capabilities allow us to serve customers looking to launch customized motorcycle oil additives, ensuring competitive pricing and premium quality standards backed by ISO certifications.
