Explore our selection of specialized engineering lubricants formulated for extreme environments, mechanical optimization, and equipment longevity.
How global emission targets, downsized turbocharged gasoline engines, and the evolution of hybrid powertrains are shifting the lubricant paradigm.
Modern Turbocharged Gasoline Direct Injection (TGDI) engines operate under extreme mechanical stress. Low-Speed Pre-Ignition (LSPI) poses a threat to engine integrity. Our premium petrol engine formulations utilize specialized calcium-magnesium detergent packages that prevent premature combustion, safeguarding cylinder walls and piston rings.
Automotive manufacturers are forced to comply with strict CO2 regulations. Transitioning to ultra-low viscosity grades like 0W-16 and 0W-20 requires high shear stability. Our synthetic formulations employ proprietary shear-stable viscosity index improvers (VIIs) that retain oil film thickness under extreme heat while minimizing friction during boundary lubrication phases.
With engines operating at elevated thermal margins, standard mineral lubricants oxidize rapidly, generating varnish and carbon deposits. Our fully synthetic formulations utilize Group III synthetic base oils combined with advanced antioxidant packages to prolong oil drain intervals (ODI) and maintain clean valvetrains.
Established in 2009 and headquartered in Zibo, Shandong, Shandong Longhai Lubrication Technology Development Co., Ltd. is a high-tech enterprise integrating R&D, production, and sales. Deeply involved in the lubricant industry for over 15 years, the company has built a complete industrial chain system dedicated to providing high-quality lubrication solutions for global industrial and transportation fields.
Longhai Technology owns its own brand "Century Longhai" and the international strategic cooperation brand British "A Ba" series of products. The brand is fully insured by PICC (China People's Insurance Company) for robust quality assurance. Our diverse product portfolio spans diesel engine oil, gasoline engine oil, gear oil, hydraulic transmission oil, anti-wear hydraulic oil, special engineering machinery oil, natural gas engine oil, full synthetic oil, automotive urea solutions, antifreeze, industrial oil, and automatic transmission oil.
Our manufacturing complex is engineered to guarantee quality control, volume stability, and swift international delivery logistics.
Spanning over 131 acres, our manufacturing facility houses intelligent production and blending lines alongside precise testing laboratories. We have implemented advanced automatic metering and filling equipment that utilizes volumetric and mass-flow principles.
This system achieves a filling accuracy within 1‰ to 2‰ while increasing operational throughput speed by 20% to 35%. This level of automated standardization allows us to meet volume export orders while minimizing risk of batch contamination.
To ensure our petrol engine oils meet global standards, Shandong Longhai holds verified quality management credentials, providing our international partners with transaction reliability.
We maintain strict operating procedures certified under ISO 9001:2015 (Quality Management System), ISO 14001:2015 (Environmental Management System), and ISO 45001:2018 (Occupational Health & Safety).
Our formulas carry international validation, including automatic transmission Mercedes-Benz certifications, ensuring the lubricants perform predictably under strict OEM operating envelopes.
Our petrol motor oil configurations are formulated in accordance with American Petroleum Institute (API) SP, SN Plus, SN, and SL classifications, as well as European ACEA standards.
We collaborate with distributors, retail brands, and fleet managers worldwide to deliver custom chemical formulations and packaging designs tailored to specific markets.
Fully synthetic and semi-synthetic lubricant formulations tailored to vehicle requirements, climatic conditions, or regional market positioning to meet international standards such as API/ACEA.
We support small-scale trial runs up to large-scale production runs, covering engine oil, transmission oil, and industrial lubricants with flexible filling specifications.
Certified by ISO 9001, IATF 16949, and other bodies, we provide third-party laboratory verification reports to ensure global regulatory compliance.
Our creative team offers structural packaging design, custom labeling, and complete technical document localization to support your brand's market introduction.
Our structured onboarding flow minimizes lead time and ensures quality control transparency from initial analysis to shipping delivery.

These formulations are field-tested and selected for their protective properties and wear mitigation across diverse applications.
Ultimate Protection for modern turbocharged gasoline direct injection engines. Specifically protects against LSPI.
Fully synthetic base formulation engineered to prevent deposits and varnish under high operating temperatures.
Advanced wear protection package optimized for older naturally aspirated vehicle platforms.
Standard performance formulation offering wear protection for light utility fleets.
Heavy-duty synthetic diesel motor oil providing oxidation resistance and shear stability under load.
High-efficiency diesel oil ensuring particulate filter longevity and low soot emission profiles.
Lubricants must adapt to different working environments. We modify additive packages to meet regional challenges.
In cold regions like Northern Europe, Northern Asia, and Canada, lubricants require low-temperature fluidity to prevent dry starts. Our 0W-30 and 0W-40 lubricants utilize synthetic base stocks with pour point depressants (PPD) to keep the oil pumpable at temperatures down to -40°C, protecting critical engine components during the first few seconds of operation.
In the Middle East and Africa, engines run hot under high ambient dust levels. Dirt ingress acts as a catalyst for abrasive wear. Our formulations feature shear-resistant polymer networks and high-detergency levels to trap particulate impurities, keeping them suspended and preventing carbon buildup.
Hybrid vehicles experience frequent stop-start cycles, resulting in low engine operating temperatures that can lead to moisture condensation and acid formation. We are designing low-viscosity solutions (such as 0W-8 and 0W-16) with enhanced anti-corrosion additives to prevent water emulsification and rust in hybrid sumps.
