Explore our tier-one lubricants engineered to satisfy demanding OEM thresholds, operational specifications, and extreme thermal conditions.
Turbocharged Direct Injection (TDI) engines are famous for high thermal efficiency and torque density, but they also present demanding lubrication challenges. High-pressure combustion generates severe mechanical stress, while turbochargers expose the oil to thermal extremes. Standard lubricants fail under these environments, leading to viscosity breakdown, oxidative degradation, and carbon deposits.
Shandong Longhai Lubrication Technology Development Co., Ltd. addresses these challenges by formulating lubricants that withstand severe wear. Established in 2009 in Zibo, Shandong, our R&D combines synthetic base oils with advanced additive packages. Under our main brand "Century Longhai" and our partner brand "A Ba", we develop lubricants that optimize fuel efficiency and prolong engine life.

Critical insights for procurement directors, logistics managers, and wholesale distributors dealing with high-performance engine lubricants.
Modern emissions regulations require mid-SAPS and low-SAPS lubricants to protect diesel particulate filters (DPF) and selective catalytic reduction (SCR) catalysts. Buyers must select formulations that prevent ash buildup in these systems.
Modern fleet owners demand engine oils matching specific OEM standards (e.g., Mercedes-Benz, Volkswagen, Cummins). Shandong Longhai’s automatic transmission fluids and motor oils carry official OEM approvals, guaranteeing drop-in reliability.
Global supply chain disruption necessitates reliable manufacturing partners. Operating on a 131-acre high-tech footprint, Shandong Longhai ensures robust supply security, shielding clients from fluctuations in raw materials and logistics.
Our Zibo facility implements advanced automation to ensure batch consistency and high output. We operate automated blending and filling equipment that regulates input materials and monitors system parameters in real time.
By using metering filling technology, we achieve filling accuracy within 1‰ to 2‰. This automated process increases production speeds by 20% to 35% compared to conventional methods. This helps us stabilize lead times, minimize material waste, and support competitive wholesale pricing for global markets.
We maintain ISO 9001:2015, ISO 14001, and ISO 18001 certifications. Our automatic transmission fluid holds official Mercedes-Benz certification, reflecting our commitment to global quality standards.

How Shandong Longhai engineered lubricants perform under demanding commercial and industrial conditions.
In high-temperature logistics corridors, heavy diesel engines experience thermal stress that can thin lubricants, leading to wear on bearings and turbochargers. Shandong Longhai’s synthetic TDI engine oils use thermal-stable viscosity index improvers. These formulations maintain a reliable protective film at high operating temperatures, reducing friction and oil consumption.
In cold mining environments, conventional lubricants thicken, delaying oil circulation during engine start-up. This lag can cause direct metal-on-metal contact. Our low-viscosity synthetic oils maintain fluid properties at low temperatures, ensuring rapid oil delivery to engine components during cold starts to prevent wear.
High-pressure industrial hydraulic systems require fluid that resists thermal shear and degradation. Our anti-wear hydraulic fluids prevent sludge and varnish formulation, protecting servo-valves and pumps. This thermal stability helps extend oil drain intervals and maintain system efficiency.
