Specifically matched and optimized for passenger cars, hybrid engines, and CNG-converted vehicles navigating the challenging driving conditions of Dhaka, Chittagong, and major Bangladeshi transport corridors.
Bangladesh is witnessing unprecedented infrastructure modernization and urbanization. From the buzzing highways of Dhaka to the strategic shipping gates of Chittagong, the demand for high-tier lubricating oils is scaling at an exponential rate. However, the local operational landscape presents harsh challenges for internal combustion engines: extreme monsoon humidity, high ambient temperatures exceeding 40°C in summer, heavy traffic jams causing extended idling, and high particulate matter (dust) levels in the air.
Additionally, a unique aspect of the Bangladesh passenger market is the widespread adoption of dual-fuel setups. A significant percentage of gasoline vehicles operate on Compressed Natural Gas (CNG). CNG combustion runs significantly hotter than gasoline, causing accelerated oxidation, nitration, and valve-seat recession. Standard motor oils quickly lose their alkaline reserves (TBN) and viscosity indexes under these circumstances. Our premium API SJ, SL, SN, and SP engine oils are engineered with robust thermal-oxidative stability, advanced dispersants, and shear-stable polymer modifiers to combat these exact localized challenges.
Established in 2009, perfecting lubrication formulations for harsh climates.
Massive production base covering 131 acres with automated lines.
Advanced volumetric metering system for consistent container yields.
Extensive logistical footprint supplying heavy industrial markets.
Shandong Longhai Lubrication Technology Development Co., Ltd. was established in 2009 and is headquartered in Zibo, Shandong. As a certified national high-tech enterprise, we integrate research and development, smart manufacturing, and global export services. Deeply rooted in the lubrication industry for over 15 years, we operate a fully integrated supply chain system capable of manufacturing everything from premium automotive engine oils to high-performance industrial gear, turbine, and hydraulic fluids.
We own the well-known domestic brand "Century Longhai" and represent the international strategic cooperation brand British "A Ba" series. To provide absolute reliability and safety guarantees for our overseas importers, all our products are fully insured by the People's Insurance Company of China (PICC) for comprehensive quality liability insurance. This guarantees peace of mind for distributors and large-scale fleet operators throughout Bangladesh.
We empower local lubricant brands and large import distributors in Bangladesh to design, formulate, and package their own branded lubricants using our world-class blending facilities.
We tailor viscosity curves, base oil selection (Group I, II, or III), and additive chemistries (API SP, SN, SL, SJ, or diesel CK-4/CJ-4) to meet local requirements, weather profiles, and client price points.
From trial runs to massive bulk orders, we scale production smoothly. Our plant supports small bottle packaging (1L, 4L, 5L) up to large steel drum options (200L) and IBC totes.
Every single batch undergoes dynamic laboratory verification for viscosity index, flash point, pour point, TBN value, and shear stability before packing. Certified third-party reports are provided.
Our dedicated design and label printing teams support complete OEM brand integration. We assist in creating premium bottle graphics, compliance labeling, and secure carton packaging.
Understand client parameters, local market pricing targets, and API specs.
Develop lab-tested sample blends utilizing premium additive packages.
Simulate extreme load, heat, and shear scenarios for quality approval.
Execute high-precision automated filling at speed, with accuracy limits of 1‰.
Ship via Qingdao Port directly to Chittagong with full compliance and LC tracking.
Through robust QA standards, our products carry top domestic and international certifications. This compliance profile ensures clean custom entries under Bangladesh Customs regulations and BSTI guidelines.
Explore our multi-sectoral range including heavy-duty diesel engines, high-pressure industrial gearings, and high-performance turbine systems designed to maximize machine lifespans in humid monsoon climates.
Dhaka suffers from massive traffic jams. Passenger cars sit idle with engines running for hours, generating high sludge and varnish. Our API SN and SP fully synthetic oils prevent deposit buildup and maintain perfect fluidity to prevent start-up wear.
Highways between Chittagong port and Dhaka handle heavy-duty trucks operating under peak loads. Our CJ-4 and CK-4 heavy-duty diesel oils deliver immense shear protection and carbon soot handling to secure diesel engine life cycles.
Two-wheeler delivery vehicles require special wet-clutch friction parameters. Our 4T Motorcycle Special Oil ensures smooth clutch engagement and prevents engine overheating during continuous stop-start delivery cycles.
Bangladesh's textile factories rely on heavy industrial air compressors and turbines. Our hydraulic fluids and turbine oils offer premium demulsibility to separate moisture easily, keeping equipment safe from rust in damp conditions.
Steel mill, cement plant, and paper manufacturing gear systems operate under high torque. Our L-CKC and L-CKD industrial gear oils are formulated with extreme pressure (EP) chemistry to prevent surface pitting and tooth wear.
Passenger auto-rickshaws converted to CNG burn fuel at higher dry heat. Our premium formulations are optimized to control oxidation and maintain thermal stability under high thermal stresses.
The South Asian lubricants market is shifting away from low-tier monogrades to high-tier multigrades and synthetic formulations. Driven by national fuel emission guidelines and engine design shifts by major manufacturers like Toyota, Suzuki, and Honda, high-viscosity mineral oils are being replaced by high-performance synthetic lubricants. The rise of hybrid petrol engines also demands lower viscosity classes like 0W-20 or 5W-30 to save fuel without compromising on wear protection.
Importers in Bangladesh who source advanced synthetic oils (API SN/SP) directly from Chinese manufacturing bases gain a key competitive edge. By working directly with a primary blending factory like Shandong Longhai, importers bypass expensive trade markups, secure custom formulations for hot climates, and establish high profit margins under their own brands.
