Discover our high-grade industrial lubricants, diesel formulas, and transmission fluid lines designed to deliver ultimate machinery and engine protection.
Established in 2009 and headquartered in Zibo, Shandong, the industrial heart of China's chemical industry, Shandong Longhai Lubrication Technology Development Co., Ltd. is an advanced, high-tech manufacturing enterprise specializing in the R&D, blending, packaging, and distribution of top-tier lubricants. With over 15 years of industry excellence, we have built a fully integrated supply chain designed to support global commercial, automotive, and heavy-duty machinery industries.
We own the domestic household brand "Century Longhai" and hold a long-term strategic partnership with the British premium brand "A Ba" series. Our products are formulated using internationally sourced Group II, III, and IV (PAO) synthetic base oils combined with premium additives from global leaders like Infineum, Lubrizol, Afton, and Chevron Oronite.
Our product lineup covers diesel engine oils, gasoline engine oils, heavy-duty industrial gear oils, anti-wear hydraulic oils, special equipment fluids, automatic transmission fluids (ATF), eco-friendly antifreeze, and diesel exhaust fluids. Every bottle is backed by quality liability insurance from PICC (People's Insurance Company of China), establishing maximum peace of mind for distributors and end-users.

Why Longhai is the preferred partner for wholesale distributors and private label OEM buyers globally.
Our facilities utilize digital controls and high-precision metering devices. Our filling lines ensure a metering accuracy of 1‰ to 2‰, increasing throughput speeds by 20% to 35% over standard configurations, ensuring consistent viscosity index control and zero contamination.
We allocate over 5% of annual revenue to internal R&D. Our state-of-the-art laboratory features automated ICP spectrometers, CCS simulators, and high-temp shear testers to run ASTM-compliant quality control on every raw material batch and finished product.
Located in Zibo, Shandong, we benefit from direct proximity to base oil refineries and raw chemical sources. This localization lowers input logistics costs and guarantees consistent chemical supply lines even during global material squeezes.
Keeping ahead of regulatory upgrades, automotive design changes, and eco-friendly standards.
Modern Direct Injection (TGDI) engines operate under high pressures, exposing them to Low-Speed Pre-Ignition (LSPI) which can destroy pistons. Longhai's new SP-grade formulations are developed with optimized calcium and magnesium detergent balances specifically to neutralize LSPI risks while maintaining advanced soot dispersancy.
Global standards demand lower tailpipe emissions. The transition from 10W-40 and 5W-30 down to ultra-low viscosity fluids like 0W-16 and 0W-20 requires high HTHS (High-Temperature High-Shear) index stability. Longhai integrates advanced star-shaped polymer viscosity index modifiers to prevent oil-film shearing at micro-clearance friction points.
From freezing transportation corridors to high-load mining fields, we engineer customized protection.
Challenge: Long-haul trucking demands oils that handle soot build-up, acid generation, and extended drain intervals (ODIs).
Solution: Longhai CI-4 Plus and CJ-4 synthetic diesel lubricants offer high Total Base Number (TBN) retention to neutralize acidic combustion by-products, protecting bearings and rings over long runs.
Challenge: Manufacturing systems operate under continuous shear pressures and moisture exposure, risking sludge and valve stiction.
Solution: Our Anti-Wear Hydraulic Fluid family utilizes zinc-free and ashless additives providing superior water separation (demulsibility) and rust prevention under high thermal cycles.
Challenge: Air compressors and refrigeration systems operating in extreme cold require rapid startup fluidity to prevent dry friction wear.
Solution: Professional refrigeration and turbine oils with pour points down to -45°C, providing instant pumpability and excellent seals without swelling synthetic elastomer gaskets.
Custom formulations, high-speed automated packaging, and regulatory certification processing under one roof.
Our engineering laboratory designs fluid solutions tailored to your market's regional climate, machinery needs, and target pricing. We adjust pour point depressants, anti-foaming agents, and friction modifiers to construct optimal properties, meeting specifications across API, ACEA, JASO, and ILSAC structures.
Uncompromising compliance with international standards ensures our products perform under the harshest conditions.
Longhai Technology operates under strict quality management frameworks, having achieved ISO 9001:2015 (Quality), ISO 14001:2015 (Environmental Management), and ISO 45001:2018 (Occupational Health and Safety) certifications. Furthermore, our automatic transmission products carry direct Mercedes-Benz approvals, validating the chemical precision of our formulations.
Our reliable partner pipeline ensures swift communication, design verification, and logistics deployment.
We analyze viscosity targets, application climates, and budget margins.
Custom chemistry configuration using top base oils and additives.
Rigorous test bench runs to verify physical and chemical properties.
Automated filling, custom labeling, and high-efficiency packaging.
On-going quality tracking and market technical assistance.

We use premium hydrocracked Group II/III or PAO synthetic base oils coupled with highly shear-stable ethylene-propylene copolymer (OCP) or radial polymethacrylate (PMA) viscosity index modifiers. This guarantees that our oil preserves its film thickness under high heat (HTHS) while flowing smoothly during cold startups.
Yes. Our laboratory is equipped to formulate passenger car and heavy-duty diesel oils matching various ACEA standards (e.g., A3/B4, C3, E6/E9). We integrate specific SAPS (Sulfated Ash, Phosphorus, Sulfur) additive profiles to protect emission exhaust catalyst and diesel particulate filter (DPF) units.
Depending on packaging sizes (e.g., 1L bottles, 4L canisters, or 200L drums), our MOQs are highly flexible. We support small trial blending batches for market tests, which scale up to high-volume continuous shipments. Contact our sales department to receive a tailored quotation.
Our location in Zibo has direct highway access to Qingdao Port, one of China's largest container shipping hubs. This ensures shipping container turnaround times are minimized, keeping ocean freight transport prompt and economical.
