Engineered for high thermal stability, extreme boundary lubrication, and optimized friction coefficients across diverse operational contexts.
In the contemporary industrial and automotive landscape, lubrication is no longer viewed merely as an operational utility; it is a critical variable in system efficiency, emission mitigation, and asset lifecycle optimization. As heavy industry and transportation systems scale up operational parameters, petrol and diesel engine lubricants must withstand increased mechanical shear, high thermal profiles, and aggressive chemical degradation pathways.
At Shandong Longhai Lubrication Technology Development Co., Ltd. (established in 2009, headquartered in Zibo, Shandong), we have spent more than 15 years optimizing the chemical architectures of our base oil mixtures and advanced additive packages. Under our flag brand "Century Longhai" and international strategic brand British "A Ba", our design focus bridges the gap between raw chemical endurance and next-generation environmental compliance.
Developing molecular resilience for the next generation of internal combustion engines and hybrid propulsion configurations.
Optimized to eliminate Low-Speed Pre-Ignition (LSPI) in gasoline direct injection (GDI) and turbocharged engines, protecting timing chains from high wear risks.
Deep molecular engineering into formulation regions of 0W-16, 0W-12, and 0W-8. Reducing hydrodynamic friction losses while maintaining a boundary film.
Addressing short engine runtime cycles and low operating temperatures in PHEV/HEV setups. Combats condensation, acid accumulation, and emulsion degradation.
Our formulation engineering revolves around a synthetic matrix utilizing high Viscosity Index (VI) Group III plus and Group IV (PAO) base oils. Infused with ashless dispersants, shear-stable viscosity index improvers (VII), and high-efficiency anti-wear (AW) compounds (such as advanced organic zinc dialkyldithiophosphates), our oils formulate a dynamic protective film. This film prevents metal-on-metal contact during thermal spikes and extreme mechanical boundary conditions.
Scaling operational capacity with ultra-high precision, automated logistics, and strict international standard conformity.
Operating from our 131-acre state-of-the-art manufacturing facility in Shandong, our production model operates on a Smart Factory paradigm. By digitizing our blending procedures, we maintain chemical conformity batch after batch, achieving an annual operational throughput capacity of over 200,000 metric tons.
Traditional volumetric filling systems display volume fluctuations when fluid viscosity responds to ambient temperature changes. Longhai Technology overcomes this by employing high-precision mass flow metering filling technology. This system guarantees a high accuracy rate of 1‰ to 2‰.
Simultaneously, this automated packaging setup boosts output efficiency by 20% to 35%, ensuring rapid order fulfillment for our global distribution network. From small 1-liter consumer packaging to 1,000-liter IBC containers, packaging precision is maintained without compromises.
High-integrity lubrication solutions tailored to the operational demands of heavy transportation, manufacturing, and high-load industrial machinery.
Minimizes soot-induced wear, high-temperature ring deposits, and corrosive wear in long-haul shipping applications. Meets API CK-4 and CJ-4 standards.
Formulated with micro-pitting resistance for industrial gear systems (L-CKC/L-CKD) and anti-wear hydraulic oil for high-pressure systems.
High-efficiency rotary screw air compressor oils, refrigeration compressor oils, and thermal-oxidation resistant turbine lubricants.
