High-performance formulations engineered to satisfy rigorous international API and JASO specifications, designed for extreme durability and optimal machinery performance.
Established in 2009 | Headquartered in Zibo, Shandong, China
As a leading high-tech enterprise integrating R&D, advanced production, and comprehensive sales channels, we have been deeply involved in the global lubrication industry for over 15 years. We own the domestic brand "Century Longhai" and coordinate international strategic operations under the British "A Ba" series. Our products are backed by liability insurance from PICC (People's Insurance Company of China), providing ultimate quality assurance for our global buyers.
Our production plant stretches across 131 acres, achieving an annual manufacturing capacity of 200,000 tons. By implementing precision automated blending kettles and high-throughput packaging facilities, we serve customers in over 139 cities domestically and export extensively to regions including Southeast Asia, South America, Eastern Europe, and the Middle East.
Leveraging advanced manufacturing clusters in Shandong to supply high-spec lubricants globally.
Our blending facility integrates high-precision mass flow meters and automatic batching control systems. We maintain a filling and dosing accuracy tolerance within 1‰ to 2‰. This ensures consistent additive distribution and shear-stability across every batch of synthetic base oil.
Located in Zibo, Shandong, a major petrochemical refining cluster in China. We secure top-tier Group II/III base oils directly from major refiners, while formulating with premium additives from global leaders such as Lubrizol, Infineum, and Afton to maximize performance.
Our fully automated packaging lines run 20% to 35% faster than standard regional competitors. This high throughput ensures rapid production turnaround, helping global distributors reduce lead times and optimize inventory levels.
Fully sealed, intelligent lines that prevent cross-contamination, ensuring absolute purity from formulation blending to final packaging.
Equipped with analytical instruments to monitor Viscosity Index, Flash Point, CCS, and TBN limits for every batch.
Spacious, climate-regulated warehouse zones built to maintain feedstock and finished goods integrity under optimal temperatures.
Understanding the transition towards low-viscosity, high-shear, and environmentally compliant fluid solutions.
Global regulatory frameworks focusing on carbon footprint reductions and fuel efficiency have accelerated the migration from mineral-based SAE 20W-50 grades to highly refined synthetic formulations like SAE 10W-30, 10W-40, and 5W-40. These low-viscosity oils reduce internal fluid friction, boosting engine efficiency without sacrificing structural film thickness under high-temperature conditions.
Moreover, modern high-RPM motorcycle engines operate under severe thermal stress. This demands robust synthetic ester or polyalphaolefin (PAO) base fluids. These formulations exhibit high Viscosity Indexes (VI), showing minimal viscosity changes even under intense heat and mechanical load.
Unlike passenger car engines that utilize separate lubricants for the engine and gearbox, four-stroke motorcycles typically share a single lubricant bath for the engine, wet clutch, and transmission gears. This multi-functional environment requires precise frictional behavior to prevent clutch slippage while protecting gear teeth from pitting and spalling.
Formulations must comply with JASO MA2 specifications (as defined in JASO T 903:2016). This standard tests critical performance metrics like Static Friction Index (SFI), Dynamic Friction Index (DFI), and Stop Time Index (STI). Our formulations are balanced to deliver maximum power transfer, prevent clutch slippage, and provide extreme-pressure wear protection.
Designed for multi-cylinder engines operating at over 12,000 RPM. Requires high shear stability index (SSI) polymers to resist mechanical shear breakdown.
Engineered for frequent stop-and-go driving. Active dispersants prevent carbon and sludge deposits, extending engine life under varying thermal loads.
Heavy duty, high-load operation requires robust anti-wear chemistry (ZDDP) and high TBN reserves to neutralize acidic combustion byproducts.
Beyond selling lubricants, we deliver comprehensive fluid optimization programs to help global enterprises lower their Total Cost of Ownership.
By deploying synthetic engine oils with extended drain intervals, we help fleet operators reduce routine oil changes, minimizing maintenance downtime and lowering waste disposal costs.
We offer end-to-end customized packaging, label design, and technical data sheet (TDS/MSDS) creation. This allows international brand owners to launch high-performance lubricants compliant with local regulations.
We assist our wholesale buyers by providing batch testing, lab analysis, and technical consultations. This helps track wear particles, pinpoint contaminants, and optimize drain intervals in real-world operating conditions.
A streamlined, transparent partnership process from initial inquiry to final international shipping.
We work with you to define specific viscosity indices, base stock preferences, and required certifications (API, JASO, ACEA) tailored to your target market.
Our laboratory blends base oils and additive chemistry in the optimal ratios. This creates custom formulations tailored to high temperatures or cold-start conditions.
Every sample undergoes testing for kinematic viscosity, shear stability, CCS viscosity, and pour point to ensure compliance before bulk blending begins.
Utilizing our automated filling lines, we blend and package your order with a volume accuracy within 1‰ to 2‰, completing your shipment on time.
We provide ongoing batch traceability files, shipping documentation, customs support, and formulation updates as international standards evolve.
Helping procurement managers navigate international imports with comprehensive quality assurance and certification documentation.
Shandong Longhai has passed ISO-9001-2015 quality system certification, ISO 14001 environmental management system certification, and ISO 45001 / OHSAS 18001 occupational health management system certification. We have also achieved Mercedes-Benz approvals for transmission fluids, ensuring our production processes meet rigorous global OEM standards.
Transporting industrial lubricants across borders requires meticulous regulatory compliance. We provide complete Safety Data Sheets (SDS) containing detailed hazard classification codes, handling recommendations, and spill containment protocols aligned with national standards.
We manage all shipping logistics out of Qingdao Port, using secure flexitanks, IBC totes, steel drums, or small retail cartons to ensure safe, spill-free international transport.
