Explore our high-performance formulations engineered to satisfy stringent API and ACEA specifications under extreme working environments.
How Shandong Longhai is pioneering next-generation formulation chemistry to meet global emission standards and fuel efficiency mandates.
The global heavy-duty engine oil (HDEO) sector is transitioning through its most transformative era. Driven by strict global limits on greenhouse gases (GHG) and exhaust emissions, modern diesel power units run hotter, handle heavier loads, and utilize complex aftertreatment arrays. Our technical focus remains dedicated to addressing these requirements with low-viscosity HDEO solutions that guarantee wear protection and extended drain intervals.
Developing API CK-4 and FA-4 oils (such as 5W-30 and 10W-30) to reduce viscous drag within heavy-duty engine components, facilitating up to a 1.5% fuel saving compared to conventional 15W-40 oils.
Applying custom low-SAPS (Sulfated Ash, Phosphorus, and Sulfur) technologies designed to safeguard and prolong the operating lifespan of diesel particulate filters (DPFs) and SCR catalysts.
Developing molecular polymers that offer high shear stability to maintain oil film protection under peak engine loads, alongside soot dispersants that limit oil thickening.
Our research and development program targets compatibility with Euro VI emission standards and China VI targets. By utilizing synthetic Group III base oils combined with shear-stable viscosity index improvers, our lubricants provide dynamic oil film protection even when oil temperatures exceed 150°C.
Shandong Longhai Lubrication Technology Development Co., Ltd. was established in 2009 and is headquartered in Zibo, Shandong. We are a high-tech enterprise integrating R&D, production, and sales. Deeply involved in the lubricant industry for more than 15 years, our team has built a complete industrial chain system dedicated to providing high-quality lubrication solutions for the global industrial and transportation fields.
As a reliable lubricant manufacturer in the industry, Longhai Technology owns its own brand "Century Longhai" and the international strategic cooperation brand British "A Ba" series of products. Our portfolio spans diesel engine oil, gasoline engine oil, gear oil, hydraulic transmission oil, anti-wear hydraulic oil, special engine oil for engineering machinery, special oil for natural gas, full synthetic oil, automotive urea solution, antifreeze, special engine oil for motorcycles, industrial oil, and automatic transmission oil.
To provide peace of mind to our distributors and customers, our brand is fully insured by the PICC (People's Insurance Company of China), guaranteeing strict product liability and quality insurance across all global shipping zones.
Inside our automated manufacturing system, ensuring blending accuracy, volume capacity, and stable supply lines.
Shandong Longhai operates advanced blending systems along with fully automatic production and filling lines. The filling equipment utilizes precision metering principles, making it suitable for a wide range of lubricating oils. By maintaining a filling tolerance of just 1‰ to 2‰, we help reduce material wastage and maintain weight accuracy across all package sizes.
Implementing this precision filling automation has boosted line speeds by 20% to 35%. This efficiency enables us to process large bulk orders quickly, reduce dispatch times, and support stable supply chains for our international distributors.
Our annual R&D investment accounts for more than 5% of our annual revenue. We have established strategic partnerships with major domestic universities and research institutions to continually refine our formulation chemistry.
