Explore our high-performance synthetic and mineral lubrication range designed to protect heavy machineries under extreme conditions.
Modern industrial expansion demands more than raw base oils; it demands advanced hydrocarbon engineering. As a premier wholesale crude oil products and specialty petroleum manufacturer, Shandong Longhai Lubrication Technology Development Co., Ltd. addresses the global shift toward ultra-pure, high-viscosity index lubricants. Environmental regulations, such as Euro VI and China VI emission limits, combined with the structural changes of machinery operating under severe friction thresholds, require high-performance synthetic fluids and premium additives.
From primary refining stages to structural base oil categorization (API Group I to Group V), the international downstream sector relies heavily on suppliers who can integrate raw chemical supply lines with custom additive engineering. Longhai bridges this gap by utilizing high-quality base oil streams combined with precision synthesis to supply heavy industrial gear oils, synthetic diesel oils (API CK-4/CJ-4), and tailored motorcycle and automatic transmission fluids.
Our infrastructure optimizes molecular alignments during formulation to guarantee high shear stability, minimal evaporation rates, and outstanding thermo-oxidative resistance. In markets spanning Europe, Southeast Asia, South America, and Africa, global procurers depend on our capability to minimize down-time, protect mechanical assets, and optimize capital investment costs.
Established in 2009 and headquartered in Zibo, Shandong Province—a renowned regional hub for petrochemical excellence—Shandong Longhai Lubrication Technology Development Co., Ltd. has developed into a high-tech enterprise integrating R&D, precision blending, testing, and global sales. For over 15 years, we have optimized our internal supply chain to provide premium lubrication solutions to global transportation, construction, and heavy manufacturing sectors.
Our proprietary brand, "Century Longhai", along with our strategically partnered international line, the British "A Ba" series, represent the pinnacle of downstream petroleum refining and formulation. Underwritten by the People’s Insurance Company of China (PICC), our product quality guarantees maximum structural reliability and operational risk-mitigation for our clients.
Our comprehensive catalog spans automotive engine oils, high-performance anti-wear hydraulic oils, agricultural gear oils, heavy-duty industrial transmission fluids, air compressor oils, specialized marine oils, and eco-friendly automotive urea solutions and antifreezes. Every product is refined to match or exceed API, ACEA, and specific OEM specifications.
Combining technological automation with strategic geographic positions to lower costs and elevate quality.
Our modern manufacturing facility in Zibo features highly automated blending columns and fast-rate packaging plants. Our filling production lines apply modern mass-flow and volumetric metering principles. This guarantees a filling precision of 1‰ to 2‰, minimizing waste and maintaining weight uniformity across small retail packs and large industrial drums.
This automated layout increases volumetric throughput speeds by 20% to 35% compared to traditional batch filling systems. This enables our facility to handle urgent global orders and maintain a short manufacturing cycle. Integrated raw material storage tanks, coupled with bulk transport access, ensure uninterrupted supply networks even during volatile market cycles.
By leveraging Zibo's petrochemical industrial base, we procure high-grade base oils and raw additives at optimized price points. These logistic savings are directly transferred to our global partners, ensuring premium formulations without prohibitive costs.
From lab-scale molecular design to commercial packaging—your brand, powered by Longhai technology.
Fully synthetic and semi-synthetic lubricant formulations tailored to vehicle/equipment requirements, climatic conditions or market positioning to meet international standards such as API/ACEA.
Supports small-scale trial production to large-scale production, covering engine oil, transmission oil, industrial lubricants and other full categories, filling specifications are flexible and optional.
Certified by ISO 9001, IATF 16949, etc., provide authoritative third-party test reports to ensure product performance and compliance.
We offer packaging design, label printing and technical documentation support to help you build a premium brand image.
Delivering optimal operational results under challenging environments and working conditions.
Hydraulic excavators and dump trucks operating in sub-zero or high-temperature deserts require stable viscosity values. Our anti-wear hydraulic oils and heavy-duty diesel engine oils feature high viscosity indexes and low pour points, preventing cold start cavitation and maintaining load-bearing fluid film thickness under extreme heat.
Continuous-run power plants and paper mills subject gear lubricants to mechanical shear and water contamination. Longhai's heavy-duty gear oils and turbine oils demonstrate rapid demulsibility and thermal stability, accelerating water separation and preventing micro-pitting on critical gear teeth surfaces.
Direct injection, turbocharged passenger cars require low-viscosity motor oils that prevent Low-Speed Pre-Ignition (LSPI) and chain wear. Our LONGHEAD SP Premium Motor Oil delivers piston cleanliness, mitigates combustion deposits, and enhances fleet fuel efficiency by reducing viscous drag.
Shandong Longhai strictly adheres to global quality benchmarks, environmental protections, and health safety management protocols.
To assure global buyers of our production standards, Shandong Longhai has established a quality control workflow verified by international certifications:
By blending imported base oils and premium raw additives in our advanced laboratory, we ensure that every batch exhibits high performance metrics. We collaborate with independent testing agencies (SGS, Intertek) to provide comprehensive chemical analyses, assuring buyers of absolute reliability before bulk shipments leave port.

How Shandong Longhai is leading the integration of green energy technologies with classical tribology.
Global transport systems are shifting toward 0W-16 and 0W-20 engine oils to lower fuel consumption and reduce carbon footprints. By using premium synthetic base stocks and customized friction modifiers, we formulate low-viscosity oils that provide robust engine protection even under high shear rates.
Electric vehicle (EV) drivelines demand direct-cooling dielectric properties and copper compatibility. Our R&D center is developing specialized transmission fluids that maintain stable electrical resistivity while providing wear protection for high-speed reduction gears.
Industrial activities in marine and forestry environments require biodegradable hydraulic and gear oils to prevent eco-toxicity. We are expanding our synthetic ester formulations to meet stringent environmental standards without compromising machine reliability.
