Explore our premium grade fully synthetic engine oils, advanced heavy-duty diesel fluids, and industrial wear-resistant lubricants engineered for extreme performance.
Established in 2009 in Zibo, Shandong, Shandong Longhai Lubrication Technology Development Co., Ltd. has spent over 15 years engineering next-generation lubricants. As a state-level high-tech enterprise, we operate a massive 131-acre intelligent manufacturing base with an annual production capacity of 200,000 tons. Our production lines feature world-class automation and precision laboratories designed to address custom requirements for global heavy industries, marine transport, automotive, and logistics networks.
Our proprietary brand, Century Longhai, together with our strategic international partnership brand, the British "A Ba" series, represents the highest level of mechanical wear protection. All our products are backed by product quality liability insurance from PICC China People's Insurance Company, guaranteeing unparalleled reliability and risk mitigation for industrial buyers worldwide.
Today's petroleum industry is defined by demanding operational environments, tighter environmental standards, and the search for operational efficiency. Modern engines and industrial machinery operate under higher temperatures, extreme pressures, and extended drain intervals. As a result, standard formulations are no longer sufficient. High-performance lubricants must now prevent oxidative degradation, resist shear breakdown, and optimize fuel economy. Longhai Technology addresses these challenges by sourcing top-tier synthetic base stocks and blending them with advanced additive systems to guarantee long-term thermal stability and component protection.
Our systems conform to international certifications, confirming our focus on global quality control:
| ISO 9001:2015 | Quality Management |
| ISO 14001:2015 | Environmental Management |
| ISO 45001:2018 | Occupational Health |
| Mercedes-Benz | OEM Certified Approval |
Understanding the transition toward high-tech industrial formulations, smart manufacturing, and green transitions.
The transition from API Group I/II mineral oils to Group III+, Polyalphaolefins (PAO), and organic esters has accelerated. These materials show exceptional viscosity indices, ensuring uniform fluid dynamic lubrication under extreme temperature variations and minimizing cold-start wear.
Modern engine developers focus on minimizing parasitic energy losses. Our low-viscosity fluids (such as API SP grades) are designed to minimize hydrodynamic drag within the system, delivering documented fuel economy improvements while maintaining strong boundary films.
With regulations like China VI and Euro VI, emissions-compliant lubricants must feature lower sulfated ash, phosphorus, and sulfur (SAPS) content. This protects exhaust after-treatment systems (DPF/GPF/SCR) from premature poisoning and blockage.
Our commitment to continuous innovation includes allocating over 5% of annual revenue to tribology R&D.
By collaborating with leading research institutions, Longhai develops high-performance additive packages that balance multiple operational demands. Our research covers several critical areas:
Our production facilities utilize modern automated batch-blending technology to ensure consistency across batches. Metering filling systems deliver a precision tolerance of 1‰ to 2‰. This high accuracy is combined with an optimized piping design that prevents cross-contamination, ensuring that every batch meets global OEM standards.
| Technology Parameter | Traditional Method | Longhai Precision Standards |
|---|---|---|
| Blending Accuracy | ± 1.5% | ± 0.2% |
| Filling Output Boost | Baseline | +20% to +35% Increase |
| Viscosity Index Stability | Standard | Enhanced Shear Resistance |

Professional answers to common questions about oil formulations, storage, performance metrics, and industry standards.
API SP formulations are designed to address the challenges of turbocharged gasoline direct-injection (TGDI) engines. They offer improved protection against low-speed pre-ignition (LSPI), which can cause structural piston damage. Additionally, API SP oils provide better timing chain wear protection, enhanced oxidation stability, and improved fuel economy compared to SN standards.
Anti-wear (AW) hydraulic oils utilize zinc dialkyldithiophosphate (ZDDP) or ashless anti-wear additives to form a protective boundary layer on high-pressure metal contacts. This reduces metal-to-metal contact, lowers friction-induced heat, minimizes internal component wear, and helps maintain volumetric efficiency in high-pressure pumps.
The main factor is the operational load and severe environmental conditions. L-CKC is formulated for medium-duty enclosed gear drives under mild load and temperature variations. L-CKD is designed for heavy-duty industrial gears subject to shock loads, extreme pressures, and high operating temperatures, offering enhanced thermal stability, anti-emulsification properties, and micro-pitting resistance.
Shear stability measures an oil's resistance to viscosity loss caused by mechanical shear stresses in tight tolerances, such as between piston rings and cylinder walls. A low SSI indicates that the viscosity index improvers resist breaking down, preserving the oil's protective film thickness and helping maintain oil pressure throughout the drain interval.
Premium turbine oils are formulated using highly refined base oils (Group II or Group III) and antioxidant packages with low sludge-forming tendencies. They prevent thermal degradation and maintain high demulsibility, allowing water to separate quickly and minimizing chemical degradation that leads to varnish deposits on bearings and servo valves.
