Engineered to withstand extreme shear pressures, extreme temperatures, and continuous operational demands.
Established in 2009 and headquartered in the industrial heartland of Zibo, Shandong, Shandong Longhai Lubrication Technology Development Co., Ltd. is a premier, high-tech enterprise integrating R&D, advanced molecular synthesis, production, and worldwide distribution. Over 15 years, we have built a fully integrated lubrication ecosystem to support demanding industrial applications.
Under our signature brand "Century Longhai" and the British strategic brand "A Ba", we manufacture diesel engine lubricants, synthetic gasoline engine oils, high-pressure anti-wear gear and hydraulic oils, special formulation tractor fluid, and refrigeration oils. Backed by the PICC (People's Insurance Company of China), we deliver absolute reliability and peace of mind to our partners.
Our commitment extends beyond supplying fluid; we engineer system protection, helping multi-national partners lower operation costs, extend maintenance windows, and eliminate downtime.

Pioneering next-generation molecular engineering to optimize efficiency and minimize carbon footprint.
We are shifting from classic mineral oils (Group I & II) to advanced Group III hydrocracked, Polyalphaolefins (PAO), and biodegradable organic esters. These molecules present high thermal stability, high viscosity index, and minimal volatilization under continuous thermal stress.
Our lab integrates zero-sulfur nano-materials, graphene, and ionic liquids that form a microscopic sacrificial film on rubbing surfaces. This dramatically lowers boundary friction coefficients by up to 35%, drastically reducing mechanical wear.
Developing lubricants optimized with chemical markers detectable by in-line optical sensors. This allows industrial operators to track oil health parameters (oxidation level, water content, metallic debris) in real-time, changing maintenance from reactive to predictive.
From energy extraction to deep processing, we design systems that match heavy industry's demands.
Large turbines require gear oil with exceptional oxidative resistance and low sludge generation. Our synthetic turbine formulations preserve viscosity at 120°C and resist foam accumulation, protecting main bearings.
Our API CK-4 and CJ-4 synthetic diesel engine oils handle soot, reduce ring sticking, and extend oil drain intervals (ODIs) to 60,000+ miles under extreme road conditions.
Rolling mill hydraulic systems experience high pressures and moisture ingress. Our anti-wear hydraulic fluids feature fast water separation, high demulsibility, and elite filterability properties.
Longhai's advanced production complex in Shandong represents modern China Factory 4.0 design. By combining high-output machinery with digital management systems, we resolve the historical trade-off between customization flexibility and large-scale cost advantages.
Developing customizable viscosities, packaging formats, and formulations targeting unique geographic climates.
We work closely with global distributors, heavy machinery makers, and private labels to produce lubricants matching strict international standards (API, ACEA, JASO, ISO). Our testing lab develops unique formulations for extreme sub-zero, high-temperature, or high-humidity environments.
Whether you require full synthetic motor oils, heavy gear oils, or specialized industrial lubricants, our team manages packaging, compliance documentation, and laboratory certification testing.
Our sales engineers analyze physical targets, equipment specifications, target regions, and cost boundaries.
Chemists select base stocks and additives, creating trial-run samples to evaluate key parameters.
Physical properties are measured (viscosity index, flash point, pour point) alongside wear tests.
Automatic blending and packaging begin, followed by strict quality verification of all finished products.
We provide continued technical assistance, oil monitoring programs, and product customization services.
Our commitment to quality, environmental safety, and high performance is validated by global agencies.
Longhai maintains certifications in Quality Management (ISO-9001-2015), Environmental Protection (ISO-14001), and Occupational Health and Safety (ISO-18001). Our automatic transmission lubricants carry the prestigious Mercedes-Benz certification, showing our ability to meet extreme mechanical requirements.
Every product batch is traced using raw base materials and final property logs, ensuring reliable, uniform performance globally.
