At the core of this synthetic technology is molecular consistency. These lubricants feature high oxidative stability and resist breakdown when mixed with moisture or oxygen under pressure. The absence of volatile lighter elements reduces oil carryover into downstream piping, directly lowering oil replacement costs. Furthermore, synthetic formulations minimize varnish, sludge, and carbonaceous residues in valves and cooling systems, reducing system friction and saving power. This translates directly to extended drain intervals—up to 8,000 hours of continuous operations compared to the standard 2,000 hours of mineral fluids.
In high-temperature mining machinery and desert gas processing pipelines, discharge temperatures can reach up to 110°C. High-performance synthetics prevent viscosity loss, ensuring continuous lubrication films and preventing hardware galling.
For gas liquefaction and cold-storage refrigeration circuits operating at low sub-zero temperatures, the low pour-point of PAO synthetics ensures fluid mobility, preventing oil congealing in evaporator lines.
Refineries and biogas installations handling sour gas streams require chemically inert lubricants. Synthetic base stocks resist chemical attack from hydrogen sulfide and acidic compounds, preventing breakdown.
As a trusted lubricant manufacturer, Longhai Technology operates our proprietary brand "Century Longhai" alongside our international strategic partnership brand, the British "A Ba" series. Our comprehensive product catalog covers diesel engine oil, gasoline engine oil, gear oil, hydraulic transmission oil, anti-wear hydraulic oil, special engine oil for engineering machinery, natural gas engine oil, full synthetic oil, automotive urea solutions, antifreeze, motorcycle engine oil, industrial oil, and automatic transmission oil. Reflecting our focus on product quality and safety, our brands are insured by the People's Insurance Company of China (PICC) Quality Insurance.
We adopt advanced European blending technologies and testing setups, allowing us to replicate extreme physical conditions inside our laboratories. Every batch of synthetic compressor oil undergoes comprehensive performance checks—including gas-liquid chromatography, elemental analysis, and shear stability evaluations—to ensure reliable field performance.








We are developing biodegradable synthetic esters and polyols designed for sensitive applications, including offshore drilling platforms and hydropower facilities, mitigating environmental pollution risks.
Our ongoing research into nanostructured lubricant additives seeks to reduce boundary friction coefficients by 15%, lowering power consumption in large screw compressors.
In response to smart-factory initiatives, we are introducing sensor-compatible synthetic fluids designed to support real-time monitoring of viscosity index and moisture levels.
Our filling lines use weight-based metering systems designed for complex lubricants. This setup guarantees a packaging accuracy tolerance of 1‰ to 2‰. In addition to high filling accuracy, these automated systems increase packaging speeds by 20% to 35%, ensuring quick shipping turnarounds for large international volume orders.




We offer comprehensive contract manufacturing, product customization, and blending services to match specific machinery profiles, target markets, and operating environments.
Tailored synthetic and semi-synthetic lubricant recipes designed to meet international standards like API or ACEA, customized for specific climates and equipment guidelines.
Supports low-volume trial batches up to mass production runs, covering engine, gear, hydraulic, and custom industrial fluids with diverse packaging options.
We provide full lab testing documentation, custom safety data sheets, and compliance verification to help verify performance metrics before shipping.
Includes packaging layout designs, label compliance guidance, and product training sheets to support international market expansion.

Synthetic compressor oils, primarily formulated using PAO, POE, or PAG base stocks, offer better thermal and oxidative stability. They reduce carbon and varnish deposit formation at high discharge temperatures, provide low-temperature fluidity, extend fluid drain intervals up to 8,000 hours, and minimize oil carryover into the compressed air line.
We employ automated weight-based blending systems alongside precision quality control workflows. Every manufacturing run is monitored using digital telemetry to achieve a packaging output deviation within 1‰ to 2‰. All batches undergo laboratory analysis before container loading to ensure they meet ISO 9001-2015 specifications.
Yes, our R&D department provides customized formulation services. We formulate synthetic fluids to match specific operating conditions—such as extreme heat, highly humid air, or corrosive gas atmospheres—while ensuring compliance with targeted API and ACEA viscosity categories.
Standard order processing and filling takes between 14 to 21 working days after receipt of order specifications and chemical deposit validations. Our close proximity to major shipping ports in Shandong allows for prompt customs dispatch.
