Bulgaria's strategic position as a logistics gateway connecting Europe, the Middle East, and Asia has catalyzed a significant expansion in transport infrastructure. This geographic advantage, coupled with the rapid urbanization in cities like Sofia, Plovdiv, Varna, and Burgas, has driven an unprecedented demand for high-performance passenger and commercial vehicle lubricants.
The motorcycle sector, in particular, is witnessing robust growth. Recreational touring along the Balkan mountain ranges, expanding commuter scooter usage in highly congested metropolitan areas, and the burgeoning local delivery and courier networks (fueled by e-commerce giants like Econt and Speedy) demand lubricants that can perform under severe, continuous stop-and-go thermal cycles.
Importers and distributors in Bulgaria require stable, cost-effective, and fully certified supply chains that bypass local refinery monopolies. Partnering with a large-scale, technologically advanced manufacturer like Longhai Lubrication guarantees robust margin retention, customized formulation services, and guaranteed compliance with European safety standards.
Shandong Longhai Lubrication Technology Development Co., Ltd., established in 2009 and headquartered in Zibo, Shandong, is a premier high-tech enterprise integrating R&D, high-volume production, and global sales.
Over the past 15 years, we have built a fully integrated lubrication manufacturing value chain. We supply high-tier solutions under our domestic brand "Century Longhai", along with our strategic international partnership brand, the British "A Ba" series. Our comprehensive catalog ranges from API CK-4 heavy-duty diesel oils and SN/SP gasoline engine lubricants to specialized hydraulic transmission fluids, worm gear oils, refrigeration lubricants, and premium four-stroke motorcycle oils.
To secure the absolute peace of mind of our global trading partners, all our core products are backed by product quality liability insurance underwritten by the PICC (People's Insurance Company of China), demonstrating our uncompromising commitment to reliability and operational safety.
Our motorcycle lubricants are formulated to satisfy the demanding JASO T 903:2016 standard, particularly the high-friction JASO MA2 classification. This ensures smooth power transmission, zero clutch slippage, and optimal torque transfer under high loads, crucial for navigating Bulgaria's mountainous terrains.
Utilizing premium Group II and Group III synthetic base oils coupled with advanced Shear-Stable Viscosity Index Improvers (VII), our lubricants maintain their shear stability even under severe mechanical stress. This prevents thin-film boundary contact and maintains oil film pressure in hot running engines.
Engineered in accordance with Euro V and Euro VI emissions compliance guidelines, our low-SAPS (Sulfated Ash, Phosphorus, and Sulfur) additives protect modern exhaust after-treatment devices, such as catalytic converters and diesel particulate filters (DPFs), reducing the environmental footprint.
Shandong Longhai Technology provides comprehensive contract manufacturing and formulation engineering services. We enable private-label brands and industrial distributors in Bulgaria to configure bespoke lubricants optimized for European climates and regional machinery.
Detailed evaluation of viscosity profile, application, packaging parameters, and target market requirements.
Lab chemists craft specialized mineral, semi-synthetic, or fully synthetic blending formulations.
Rigorous bench testing for CCS viscosity, pour point, high-temperature high-shear (HTHS), and shear stability.
Automated dosing of base oils and premium additives (Infineum, Afton, Lubrizol) with filling precision of 1‰-2‰.
Strict packaging seal checks, container loading optimization, and coordination of EU REACH import customs documentation.
