Engineered to ensure high-durability protection and superior operational efficiency under extreme mechanical stress.
Established in 2009 and based in Zibo, Shandong, Shandong Longhai Lubrication Technology Development Co., Ltd. stands as a premier high-tech enterprise at the intersection of Tribological research, advanced synthesis, and global export infrastructure. With over 15 years of dedicated focus on the lubrication industry, we have established a fully integrated supply chain that spans base oil sourcing, precision chemical engineering, packaging fabrication, and international distribution logistics.
We own the well-regarded Chinese domestic brand "Century Longhai" alongside our international strategic partner brand, the British "A Ba" series. Our extensive range of solutions is backed by PICC (People's Insurance Company of China) quality insurance, giving our global commercial clients peace of mind and demonstrating our commitment to quality.
By blending advanced additive chemistries with highly refined base stocks (Group II, Group III, and synthetic PAO/Esters), our laboratory formulates lubricants that meet or exceed international performance indices set by standard bodies, including API, ACEA, and JASO. This allows our lubricants to deliver optimal protection under severe thermal and mechanical stresses.
The global motorcycle and heavy machinery lubrication sector is undergoing a rapid transition. Driven by strict emissions regulations, high-speed engine tolerances, and wet-clutch performance demands (such as JASO MA2 specifications), standard base oils are no longer sufficient. Achieving these targets requires advanced chemistry, reliable supply chains, and cost-effective production. As a leading Chinese manufacturer, Shandong Longhai offers key structural advantages to meet these demands.
Our production base features intelligent, automated batch-blending systems that strictly control additive-to-base-oil ratios. We employ dynamic temperature-controlled mixing pipelines to ensure additive packages disperse evenly. For packaging, our factory uses precision metering filling lines. This design maintains an accuracy margin of 1‰-2‰, prevents cross-contamination, and increases filling speeds by 20% to 35% compared to conventional operations. This optimization allows us to process high-volume international orders quickly without sacrificing quality.
We reinvest over 5% of our annual revenue directly into our internal laboratories and collaborative research projects with chemical institutes. Our team focuses on key areas such as high-temperature shear stability, anti-foaming properties for high-revving engines, and friction modifiers that protect motorcycle wet clutches. By optimizing these additive formulations, we help prevent clutch slippage while maximizing power transfer and protecting critical gear faces.
Reliability in industrial lubricant supply is built on strict quality control. Shandong Longhai is certified under ISO 9001:2015 (Quality Management), ISO 14001:2015 (Environmental Management), and ISO 45001:2018 (Occupational Health & Safety). Our automatic transmission lubricants have also received direct OEM approvals, including Mercedes-Benz certification. Every batch of product undergoes testing for kinematic viscosity, flash point, pour point, CCS (Cold Cranking Simulator), and elemental ash content before leaving our facility, ensuring consistent performance in the field.
Providing global partners with custom-tailored formulations engineered to withstand specific regional climates and vehicle demographics.
We engineer custom semi-synthetic and fully synthetic oils targeting specific viscosity ranges (e.g., 5W-30, 10W-40, 20W-50) that comply with API SP/SN and JASO MA2/MB international benchmarks.
From initial trial batches to high-volume commercial runs, our filling lines adapt to packaging options ranging from 1L bottles for retail to IBC totes and drums for industrial clients.
We back our products with third-party testing reports, environmental compliance documentation, and export clearances to streamline customs processing in your target market.
Procurement departments for international motorcycle brands, fleet logistics operations, and heavy machinery distributors must balance product reliability with competitive cost structures. A one-size-fits-all lubricant often fails under varying regional demands and operating climates.
The industry is shifting toward lower-viscosity fluids (such as 10W-30 and 5W-30) to improve fuel economy and reduce carbon emissions. However, lower viscosity can compromise film thickness under high heat. To address this, Shandong Longhai utilizes premium base stocks and advanced organo-metallic anti-wear additives. This maintains a protective boundary layer even when the fluid film thins, helping operators reduce downtime and extend maintenance intervals.
