High-durability engine oils and synthetic lubricants optimized for Osaka’s dense logistics grids, seaport heavy machinery, and severe-duty operations.
As the economic anchor of Western Japan, the Osaka metropolitan area (including Kobe and Kyoto) forms a dense industrial grid. The Port of Osaka serves as a key logistical gateway, handling millions of tons of maritime cargo annually. Consequently, heavy-duty cargo handling machinery, cranes, marine container carriers, and inland transport trucks operate around the clock. The mechanical stress imposed on these drivetrains demands lubricants of uncompromising performance.
Our tribological engineers analyze Osaka’s local environmental conditions: high humidity from coastal winds, stop-and-go heavy traffic on the Hanshin Expressway, and the thermal challenges of peak summer shipping cycles. Standard-grade lubricants rapidly degrade under these conditions, leading to oxidative thickening and varnish formation. For heavy machinery operating in Osaka, utilizing premium diesel oils such as CI-4 PLUS and CJ-4 synthetic formulations is a critical operational strategy to extend machinery lifespan and prevent unplanned downtime.
In accordance with Japan's Ministry of Economy, Trade and Industry (METI) directives and national carbon neutrality goals, the lubrication industry is undergoing a transition. Major Japanese transport fleets are migrating from older API CF-4 profiles toward advanced API CK-4 and low-viscosity FA-4 standards. This shift is motivated by the dual imperatives of lowering greenhouse gas emissions and improving fuel economy.
High-viscosity index synthetic gear oils and low-SAPS (Sulfated Ash, Phosphorus, and Sulfur) diesel motor oils are required to protect exhaust after-treatment devices, such as Diesel Particulate Filters (DPF) and Selective Catalytic Reduction (SCR) catalysts. By deploying our advanced synthetic formulations, industrial operators in Sakai, Yodogawa, and general Osaka industrial corridors can reduce boundary friction, lower operating temperatures, and comply with the stringent environmental limits enforced across the Japanese transport network.
Global procurement directors face rising raw material costs, freight volatility, and stricter environmental compliance mandates. When sourcing lubricants for critical gearboxes and heavy combustion engines in Osaka, local procurement managers evaluate the Total Cost of Ownership (TCO). Fast logistics, stable chemical blending consistency, and verifiable technical certifications are key selection criteria.
Shandong Longhai Lubrication Technology Development Co., Ltd. addresses these challenges by offering a vertically integrated supply model. We source high-grade base oils and premium additives, blending them under automated control systems to match international standards (API, ACEA, JASO). For global enterprises targeting the Kansai region, our optimized sea shipping lanes to the Port of Osaka ensure predictable lead times, minimizing inventory buffer costs while ensuring continuous manufacturing operations.
Established in 2009 and headquartered in Zibo, Shandong, Shandong Longhai Lubrication Technology Development Co., Ltd. is a high-tech enterprise integrating R&D, production, and sales. With a production base covering 131 acres and a 200,000-ton annual capacity, we serve 139 cities globally, supplying premium industrial and automotive lubricants.
Our flagship brands, "Century Longhai" and the international strategic cooperation brand British "A Ba", are backed by comprehensive product quality insurance from the People's Insurance Company of China (PICC). Our operations adhere to ISO 9001-2015 quality, ISO 14001 environmental, and ISO 18001 health management systems, with specialized Mercedes-Benz certifications validating our automatic transmission fluids.
Heavy machinery operating within marine transport corridors and Osaka’s metal-forging plants faces high shock loads and extreme shear forces. Industrial gearboxes require lubricants that prevent micro-pitting, gear tooth scuffing, and bearing failure. Our premium L-CKD heavy-duty industrial gear oils are formulated with advanced sulfur-phosphorus extreme pressure (EP) additives. These additives form a resilient tribochemical film on metallic contacts, mitigating metal-to-metal contact even under high boundary lubrication conditions.
Our engineering team works with local maintenance departments to implement oil analysis protocols. By monitoring viscosity variations, total acid number (TAN), and wear-metal concentrations, we help operators optimize oil change intervals. This active maintenance approach reduces wear rates in complex gear assemblies, lowering long-term maintenance costs for manufacturing operations across Osaka.
As the industry moves toward high-efficiency machinery, the demand for conventional lubricants is shifting toward low-viscosity, high-temperature formulations. Shandong Longhai’s R&D division is focused on three primary lubrication technologies:
Speak with our tribology experts to formulate bespoke industrial gear oils or heavy-duty diesel oils tailored to your equipment operating conditions and regional compliance standards.
Request Technical ConsultationFully synthetic and semi-synthetic lubricant formulations tailored to vehicle/equipment requirements, local climatic conditions, and API/ACEA/JASO global standards.
Supports both pilot-scale trial runs and high-volume commercial production runs. Filling options range from 1L cans to 200L drums, matching your specific supply chain needs.
Equipped with precision testing laboratories. We deliver comprehensive product certifications and third-party laboratory verification for every production batch.
Our blending facility utilizes precise automated metering units to ensure raw material addition accuracy within 1‰–2‰. This precision-focused control loop speeds up processing cycles by 20% to 35% compared to manual batching systems. For global brands seeking entry into the Japanese market or local distributors wishing to establish their own lubricant brands, we provide package design, technical documentation (SDS), and label printing services to support localized market positioning.

We answer the most common questions raised by lubrication engineers, port operators, and procurement directors sourcing lubricants for use in Japan.
Yes. Our formulations meet or exceed the performance parameters defined by global standards including API (CK-4, CJ-4, CI-4 PLUS) and Japanese JASO standards (such as JASO DH-2). Our oils undergo rigorous laboratory and engine tests to verify shear stability, high-temperature cleanliness, and soot handling. They can be safely used to replace OEM factory fills for major heavy equipment brands operating in the Osaka logistics corridor.
During summer, temperatures inside industrial gearboxes can exceed 85°C. Conventional mineral-based oils suffer thermal degradation and viscosity loss, which thins the lubricating film and increases metallic wear. Shandong Longhai’s synthetic gear oils feature high Viscosity Indexes (VI > 160). This ensures the lubricant maintains a robust lubricating film at high temperatures while remaining sufficiently fluid at winter startup temperatures to prevent wear.
We provide full CIF/FOB logistics services. We prepare all documentation required by Japan Customs, including SDS (Safety Data Sheets) matching local GHS standards, Certificates of Analysis (COA), and commercial customs declarations. Our close proximity to shipping routes allows us to deliver filled drums and bulk containers directly to Osaka Port within predictable lead times.
Our API CJ-4 and CK-4 diesel oils are formulated using low-SAPS (Sulfated Ash, Phosphorus, and Sulfur) additives. Ash-forming additives used in older oils can permanently plug Diesel Particulate Filters (DPFs). By reducing ash levels, our oils prevent DPF blockage, reduce regeneration cycles, and lower fuel consumption and maintenance costs for modern diesel fleets.
