Engineered to exceed API, ACEA, and OEM specifications. Explore our tier-one lubricants optimized for heavy machinery and extreme environments.
In the contemporary industrial ecosystem, friction reduction and thermal management represent critical variables for operational efficiency and carbon footprint reduction. The global lubricants market has evolved from simple petroleum by-products into highly engineered, chemically structured synthetic fluids. Increasing thermal loads in high-output engines, combined with strict environmental policies such as EPA Tier 4 and Euro VI, demand lubricants that can withstand severe shear stress, maintain high viscosity indices under extreme temperatures, and minimize volatile emissions.
As a global petroleum industry supplier, Shandong Longhai Lubrication Technology Development Co., Ltd. addresses these demands by engineering products that exceed industry benchmarks. Whether it is fully synthetic formulations designed to extend drain intervals or heavy-duty industrial gear oils engineered to protect against micropitting under shock loads, our technical solutions ensure system reliability across diverse operating conditions.
Operating from Zibo, Shandong—a major petrochemical and industrial hub in China—Longhai Lubrication leverages supply chain integration and raw material access to provide high-quality products at competitive price points. Our 131-acre production facility operates advanced fully automated blending and filling systems. This vertical integration allows us to procure base oils (Group I, II, III, and synthetic Group IV/V polyalphaolefins) and additive packages from global leaders and process them with precise quality control.
Our filling lines utilize metering technologies to achieve a filling accuracy of 1‰-2‰. By automating our blending and packaging workflows, we have increased production throughput by 20% to 35% compared to standard regional manufacturers. This efficiency translates directly into reduced lead times, competitive pricing structures, and consistent quality for our global B2B procurement partners.
Our commitment to quality control is backed by international certifications, including ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018 (occupational health and safety). Our transmission fluids also hold Mercedes-Benz approval, verifying their suitability for demanding European automotive hardware. Each production batch undergoes testing at our on-site laboratory to verify kinematic viscosity, viscosity index, flash point, pour point, and shear stability before release.
Additionally, our products are backed by product liability insurance from PICC (People's Insurance Company of China), providing an extra layer of commercial protection and risk mitigation for international importers and distributors.
Lubricants must be selected based on specific operational parameters, mechanical designs, and ambient conditions. Below are common deployment scenarios for Longhai Lubricants:
Heavy-duty excavators, draglines, and haul trucks require hydraulic oils and gear lubricants that maintain load-bearing film strength under extreme pressures. Our Longhai Heavy-Duty Gear Oils and Anti-Wear Hydraulic Fluids protect against abrasive wear, micro-pitting, and system degradation in high-dust and high-load environments.
For commercial fleets, minimizing downtime and optimizing fuel efficiency are critical. Our API CK-4 and CI-4 Plus fully synthetic diesel engine oils offer oxidation stability and soot handling capabilities. These oils help reduce oil consumption, keep engine components clean, and extend oil drain intervals under severe conditions.
Manufacturing machinery, including industrial air compressors and refrigeration units, requires highly stable lubricants to prevent sludge formulation. Our synthetic compressor and refrigeration oils provide thermal stability and low-temperature fluidity, helping optimize energy usage and protect equipment components.

The global lubricants sector is experiencing significant changes driven by mechanical optimization and sustainability initiatives. As industrial gearboxes shrink in physical footprint but increase in power output, conventional mineral lubricants are being replaced by high-performance synthetic alternatives. The primary trends driving research and development include:
To reduce internal friction losses in modern combustion systems, OEMs are specifying lower viscosity oils (such as 0W-16 and 0W-20). Formulating these lubricants requires high-quality Group III and Group IV (PAO) base oils to maintain protective film thickness under high shear rates, preventing wear on critical engine surfaces.
Modern turbochargers operate at elevated temperatures, which can accelerate oil oxidation, leading to deposit formation and viscosity increase. Synthetic formulations with high-quality antioxidant systems are essential to maintain oil performance throughout modern drain intervals.
The growth of electric vehicles is changing the demand for fluids. While engine oil volumes may shift, the need for specialized dielectric fluids to cool battery packs, insulate high-voltage systems, and lubricate e-axles is increasing. These fluids require precise electrical conductivity control and material compatibility.
Technical answers regarding formulations, packaging, quality control, and global trade operations.
We formulate lubricants using a range of base oils depending on application requirements: Group I and II for standard heavy machinery, Group III for modern high-performance engine oils, and Group IV (PAO) or Group V (Esters) for extreme-temperature synthetic formulations.
Our facility is equipped with automated filling systems utilizing weight-based and volumetric metering. This technology maintains a filling accuracy within 1‰ to 2‰, reducing product loss and ensuring consistent volumes across all packaging formats.
Yes, we provide full OEM/ODM services. Our laboratory can adjust physical and chemical parameters—such as viscosity index, shear stability, anti-wear additive ratios, and pour points—to optimize performance for specific operating conditions, regional climates, or target budgets.
Our manufacturing and quality systems are certified under ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018. Additionally, we hold Mercedes-Benz approvals for our transmission fluids, and all products are backed by liability insurance from PICC (People's Insurance Company of China).
Standard export orders are processed and shipped within 15 to 25 days depending on the level of customization. We ship out of Qingdao Port, Shandong, and provide full export documentation, including SDS, COAs, and bill of lading files.
