Engineered to exceed critical API and ACEA specifications, offering ultimate thermal stability, oxidation resistance, and wear protection.
In the modern automotive and industrial landscape, the demand for premium lubricants has shifted from basic frictional reduction to holistic powertrain thermomanagement, wear mitigation, and strict emissions compliance. Global standards like API (American Petroleum Institute) SP and ACEA (European Automobile Manufacturers' Association) C5/C6 demand highly complex formulations. These formulations must mitigate risks such as Low-Speed Pre-Ignition (LSPI) in turbocharged gasoline direct-injection (TGDI) engines while maintaining extreme shear stability and fuel efficiency.
As a premier Chinese lubricant manufacturer, Shandong Longhai Lubrication Technology Development Co., Ltd. has adapted to these stringent requirements. By combining localized manufacturing efficiencies with top-tier global basestock and additive technologies, we deliver lubricants that ensure long-term mechanical reliability under extreme temperature profiles and operation pressures.
The strategic partnership between China's advanced manufacturing infrastructure and established global formulation frameworks has positioned Chinese chemical manufacturers at the forefront of the international B2B procurement market.
Established in 2009 and headquartered in the industrial chemical hub of Zibo, Shandong, Shandong Longhai Lubrication Technology Development Co., Ltd. has developed into a national high-tech enterprise. Our core capabilities span across the entire vertical integration of lubricant formulation research, automated production blending, and international export distribution.
We actively market our proprietary flagship domestic brand, "Century Longhai", alongside our international strategic alliance brand, the British "A Ba" series. Our expansive product portfolio encompasses high-performance diesel engine oils, passenger car gasoline motor oils, industrial gear lubricants, synthetic transmission fluids, wear-resistant hydraulic systems oils, automotive urea solutions, eco-friendly coolants, and custom specialty lubricants. To ensure maximum peace of mind for B2B procurement partners, our products are backed by product liability quality insurance from PICC (People's Insurance Company of China).
Strategic resource allocation and automation technology allow us to deliver high-quality, cost-efficient bulk chemical supplies globally.
Our state-of-the-art facility integrates volumetric metering technology to ensure filling accuracy within 1‰ - 2‰. Automation increases overall filling line throughput by 20% - 35% compared to traditional semi-automated facilities, reducing cycle times for large B2B orders.
We operate in compliance with international standards, holding certifications for ISO 9001:2015 (Quality Management), ISO 14001:2015 (Environmental Management), and ISO 45001:2018 / OHSAS 18001 (Occupational Health). Our lubricants perform under extreme mechanical stresses.
Located in Shandong Province, Zibo offers direct access to key marine terminals (Qingdao Port) and freight rail infrastructure. This logistics network optimizes containerized transit times and freight costs for global distributions.
Customized product design, private label branding, and technical compliance support to integrate with your supply chain.
Our engineers develop customized synthetic, semi-synthetic, and mineral lubricant formulations tailored to viscosity profiles, pour point, and shear-stability requirements.
Whether managing localized batch runs or large-scale wholesale production, our logistics pipeline adapts to variable volume demands across packaging configurations.
We facilitate international certifications (ISO, IATF 16949) and secure independent third-party laboratory verification (SGS, Intertek) to ensure cross-border regulatory compliance.
We offer comprehensive graphic design, container styling, and localized labeling compliance (such as GHS-compliant SDS labeling) for your target markets.
Longhai Technology operates a structured B2B onboarding procedure. This system aligns engineering parameters with packaging requirements and delivery logistics to ensure supply consistency.

We coordinate with primary base stock suppliers and additives firms (including Lubrizol, Infineum, Afton, and Chevron Oronite). This raw materials pipeline helps maintain production stability.
Quality assurance at Shandong Longhai starts at the raw material intake point and continues through our manufacturing line. We check our blending batches via Gas Chromatography, Inductively Coupled Plasma (ICP) spectroscopy, and Cold Cranking Simulators.
Our ISO-certified systems and Mercedes-Benz automatic transmission fluid approval confirm compliance with standard automotive testing protocols. Our facilities are configured to deliver consistent fluid specifications from trial runs to commercial batches.
We invest in testing apparatus and equipment maintenance to secure product reliability. Our laboratory capabilities support both standard QA and development projects.
We align our operations with B2B supply expectations: technical precision, certified quality, and customer support.
We adapt formulation viscosity, additive concentrations, and base oil selection to meet specific vehicle and machinery requirements.
We maintain quality and environmental standards across our product ranges through ISO 9001, 14001, and 45001 certifications.
From technical analysis to batch delivery, we coordinate with your engineering and logistics teams to maintain product consistency.
Longhai maintains standard testing documentation and production records. We supply analysis certificates with every shipment to ensure traceability.
Our products undergo testing for mechanical wear, high-temperature oxidation, and cold-cranking performance.
We manufacture gasoline engine oils across various viscosity grades and API categories (from SP to SJ) to match global fleet demands.
