Engineered to deliver ultimate oxidation stability, soot control, and thermal protection under the harshest GCC operations.
The United Arab Emirates represents one of the most demanding operational environments in the world for heavy machinery, logistics fleets, marine vessels, and power generators. With ambient temperatures frequently exceeding 50°C (122°F) during the summer, combined with high humidity and airborne dust, standard lubricants degrade rapidly. This accelerated breakdown compromises engine components, leading to unscheduled downtime and expensive overhauls.
As major hubs like Jebel Ali Port in Dubai and Khalifa Port in Abu Dhabi drive massive regional distribution operations, fleet efficiency is critical. Modern diesel engines used in commercial transport demand high-performance lubricants that offer superior shear stability, thermal-oxidative resistance, and excellent soot dispersion. Standard lubricants fail to manage the intense thermal stress, making high-end formulations like API CI-4 Plus and CK-4 synthetic oils essential for continuous, safe operation.
Our heavy-duty diesel engine oils are formulated with high viscosity index (VI) base stocks and advanced thermal stabilizers to maintain a robust oil film at high operating temperatures, ensuring uninterrupted hydrodynamic lubrication.
By preventing rapid acid buildup and oxidation, our lubricants allow logistics and construction firms to safely double their drainage intervals, dramatically lowering total cost of ownership (TCO) across fleets.
Aligning with regional decarbonization policies and international engine development initiatives.
With the UAE's strong focus on emission reductions, modern fleets are transitioning to API CK-4 and FA-4 oils. These formulations offer superior shear stability and oxidation resistance, providing protection for engines running exhaust gas recirculation (EGR) and selective catalytic reduction (SCR) systems.
Moving from traditional monogrades to advanced multi-grades like 15W-40, 10W-40, and fully synthetic 5W-40. Lower high-temperature, high-shear (HTHS) viscosities reduce internal friction, boosting fuel economy without sacrificing wear protection.
Future development focuses on developing bio-based synthetic lubricants that degrade safely in agricultural and sensitive marine zones, aligning with the UAE's Net Zero 2050 strategic initiative.

Leveraging intelligent automation, bulk raw material sourcing, and efficient port logistics to support GCC demands.
Longhai's modern manufacturing base spans 131 acres and features an annual production capacity of 200,000 tons. The production line uses mass flow meters and automation to run continuous blending operations, guaranteeing consistent product quality. Our filling line uses precise metering technology to ensure a filling accuracy tolerance of 1‰ to 2‰. This high-efficiency system increases overall output by 20% to 35% compared to standard systems, ensuring rapid delivery times for large volume orders.
Operating in the UAE requires strict adherence to international and local regulatory standards. Our products comply with regulations set by the Emirates Authority for Standardization and Metrology (ESMA) and hold several key certifications.
Longhai Technology is certified under ISO 9001-2015 (Quality Management), ISO 14001 (Environmental Management), and ISO 18001 / OHSAS 18001 (Occupational Health & Safety). Additionally, our automatic transmission and engine oils carry official manufacturer approvals, including Mercedes-Benz specifications. This demonstrates that our fluids maintain consistent performance and protect heavy engines working in extreme commercial applications.
Custom-formulated lubricants tailored to extreme climates, machinery designs, and specific market positioning.
Our engineers formulate synthetic and semi-synthetic products to meet specific requirements, adjusting viscometrics and additive packages to match regional fuel qualities, operating temperatures, and international API and ACEA specifications.
Whether you require low-SAPS oils for modern diesel particulate filters (DPFs) or robust high-TBN formulations for high-sulfur diesel applications, we optimize the chemistry to match your fleet's exact needs.

Important considerations for fleet operators, distributors, and maintenance engineers.
High ambient temperatures lower the viscosity of diesel engine oil, potentially thinning the protective oil film. Selecting an oil with a high Viscosity Index (VI) (such as a premium synthetic 15W-40 or 10W-40) ensures the oil keeps its viscosity under thermal load, preventing metal-on-metal contact and bearing wear.
Fine desert dust particles can bypass intake filtration, leading to abrasive wear. Advanced diesel oils are formulated with specialized dispersants that isolate contaminants, preventing sludge formation and keeping abrasive particles suspended so they can be captured by the system filters.
Yes. API CK-4 oils feature improved shear stability and are available in lower viscosity grades, reducing fuel-wasting viscous drag. In long-haul transportation, this can reduce fuel consumption by 1.2% to 2.5% while maintaining heavy-duty engine wear protection.
You should request ISO 9001-2015 certificates for quality management, API licensing documentations, and third-party lab reports confirming ASTM parameters. For heavy commercial vehicles, matching OEM requirements like Mercedes-Benz sheet MB 228.3 or 228.51 is recommended.
