Direct export configurations engineered to surpass API standards and OEM reliability thresholds.
Analyzing B2B Procurement Intent, API Classification Standardizations, and Advanced Hydroprocessing Blending Methodologies.
The global automotive industry is experiencing an unprecedented structural transition. Downsized turbocharged gasoline direct-injection (TGDI) engines demand motor oils capable of mitigating Low-Speed Pre-Ignition (LSPI) and ensuring high thermal stability. Modern engine designs push conventional lubricants past their operational limits. Consequently, B2B procurement mandates have shifted from transactional cost-efficiency to advanced technical reliability and customized chemical parameters.
For high-volume distribution networks, fleet operators, and industrial groups, selecting a motor oil partner requires deep vetting of formulation integrity, manufacturing scale, and supply-chain logistics. Premium passenger car motor oils (PCMO) must satisfy stringent international frameworks—such as the API SP and ILSAC GF-6 standards—to guarantee lower carbon footprints, enhanced fuel economy, and outstanding wear protection.
Established in 2009 and headquartered in the industrial hub of Zibo, Shandong, Shandong Longhai Lubrication Technology Development Co., Ltd. is a recognized high-tech enterprise integrating research and development, smart manufacturing, and global sales. With more than 15 years of industry leadership, we have built a fully integrated supply network dedicated to producing elite lubrication products for automotive, transport, and heavy machinery industries.
Our brand portfolio includes our flagship proprietary brand "Century Longhai", alongside our strategic international cooperation brand, the British "A Ba" series. Operating with consumer peace of mind as our priority, our entire line is backed by comprehensive quality insurance from the PICC People's Insurance Company of China, ensuring robust risk mitigation for importers and commercial distributors worldwide.
Whether servicing large logistics fleets or supplying retail distributors, our product range covers high-grade diesel and gasoline motor oils, gear oils, hydraulic transmission fluids, high-temperature industrial greases, and eco-friendly automotive urea solutions.
Empowering global enterprises with high-volume blending output, precision manufacturing, and strategic logistics.
Our modern plant utilizes digital metering algorithms to control the flow and temperature during base oil and additive mixing. This guarantees uniform kinematic viscosity and shear stability, keeping batch variations below negligible limits.
Featuring automated inline filling heads, our factory processes diverse volume requirements from 1L containers to 1000L IBC tanks. By enhancing standard filling operations, we ensure fast turnarounds and reliable lead times for peak season demands.
We reinvest over 5% of annual revenue back into laboratory research. Partnering with top engineering universities, our product development specialists continually improve additive response mechanisms for low-emission engines.
Our quality system is verified by international standards and industry approvals.
Shandong Longhai operates in strict compliance with globally accepted management standards. Our industrial facility has passed the rigorous auditing processes for ISO 9001:2015 (Quality Management), ISO 14001:2015 (Environmental Protection), and ISO 45001:2018 (Occupational Health and Safety Systems).
Additionally, our high-performance transmission and motor oils carry official manufacturer approvals, including coveted certifications from Mercedes-Benz (MB). These strict tests confirm our products prevent wear, oxidation, and friction in passenger and commercial gear setups under severe conditions.
Our precision laboratory and test protocols ensure that every batch of base oil is vetted before blending. Finished products are tested using ASTM standards for CCS viscosity, pour point, flash point, and Noack volatility.
Custom formulations, adjustable packaging specs, and branding options tailored for global procurement partners.
We configure synthetic and semi-synthetic chemistries to match specific engine parameters, local weather patterns, and API or ACEA service specifications.
Support for container sizes ranging from 1-liter retail bottles and 4-liter/5-liter jugs to 200-liter metal drums and intermediate bulk containers (IBC).
Our team provides safety data sheets (SDS) matching GHS standards, alongside custom analysis certificates, customs document preparation, and REACH declaration support.
Our design team provides labeling layout support, graphic generation, and technical documentation to establish and build your brand identity.
A structured process ensures quality control from raw materials to delivery.
Evaluating target markets, climate conditions, vehicle specs, and certification needs.
Our engineers adjust base oils and additive percentages to achieve targeted performance benchmarks.
Conducting thermal stability, shear, and deposit tests to confirm performance integrity.
Using our automated smart facility for precise mass blending and inline filling packaging.
Handling sea freight custom procedures, delivery tracking, and technical support.
Adapting products to regional emissions regulations, customs barriers, and harsh operating climates.
Our low-SAPS (Sufated Ash, Phosphorus, Sulfur) oils preserve DPF and GPF emissions control hardware, satisfying strict Euro VI and China VI regulations.
We issue standard commercial invoices, packing lists, clean bill of lading documents, and certificate of origin files to streamline port clearances.
We adjust viscosity indices to match local operating conditions, ensuring fluid pumpability at sub-zero cold-starts or maintaining film strength in high-temperature zones.
Engineered to protect machinery in varied climates and demanding operation cycles.
Stop-and-go city traffic accelerates deposit and sludge formation. Our gasoline motor oils utilize advanced dispersants to prevent engine contamination and ring-sticking.
Diesel fleet operations face high mechanical stress and extended oil drain intervals. Our high-TBN formulations neutralize corrosive combustion acids and protect bearings from wear.
For wind energy, steel mills, and mining gear assemblies, our heavy-duty industrial lubricants prevent micro-pitting and scuffing under severe shock loads.
Addressing core concerns about order logistics, formulation testing, custom production, and quality assurance.
High-efficiency lubricants, turbine oils, and heavy-duty gear systems for demanding industrial applications.
