Why Gulf Ultrasynth GDI Was Selected as Product of the Year 2025

18 Sep 2025

Every year, the Product of the Year Awards recognise products that consumers find to be the most innovative in their respective markets. This year, voters selected Gulf Ultrasynth as Product of the Year 2025 in the Premier Engine Oil category. What were the qualities of Gulf Ultrasynth GDI that earned Gulf Oil the Product of the Year title? In short, it’s one of the most advanced synthetic engine oils available, one which raises the standards for performance, protection, and sustainability. Gulf Ultrasynth GDI consistently demonstrates an unmatched ability to meet the challenges of modern gasoline direct injection (GDI) engines.

What is Gulf Ultrasynth?

Gulf Ultrasynth GDI is a premium, fully synthetic engine oil designed specifically for gasoline direct injection (GDI) engines. These engines offer improved fuel efficiency and performance, which has led to their adoption in many modern vehicles. They also present distinct challenges, including higher operating pressures, increased combustion temperatures, and the risk of low-speed pre-ignition (LSPI). Gulf Oil’s award-winning engine oil, Gulf Ultrasynth GDI, was engineered to address these challenges directly, maximising protection and long-term performance for drivers across the Middle East and beyond.

Why Gulf Ultrasynth GDI is the Best Oil for GDI Engines

GDI technology is now the standard for modern cars, but it places increased demands on lubricants. Unlike traditional port fuel injection, GDI engines inject fuel directly into the combustion chamber under high pressure. This creates harsher operating environments and increases the risk of:

• Carbon-rich deposits, especially on intake valves, reducing efficiency and performance.
• Faster breakdown of traditional engine oils, potentially compromising protection and lubrication, and requiring oil be changed more frequently.
• LSPI, an abnormal combustion event within the engine, resulting in engine knock and potentially serious damage to piston rings and connecting rods.

Traditional mineral oils not formulated for use with GDI technology will degrade faster in these conditions, causing increased wear and resulting in costly repairs. Gulf Oil Product of the Year, Ultrasynth GDI, is manufactured with advanced additives that help it withstand the pressures of GDI engines. Its specialised chemical formulation, meanwhile, directly addresses LSPI risks, ensuring smooth, efficient combustion and extending engine life.

It’s this LSPI protection, combined with Gulf Oil’s proprietary detergent technology, that made Ultrasynth GDI stand out amongst its competitors, and win Gulf Ultrasynth Product of the Year 2025. By keeping intake valves and pistons cleaner, the oil enhances engine responsiveness and reduces maintenance requirements. Overall, this helps vehicles perform reliably for longer, no matter how demanding the driving conditions.

How Gulf Ultrasynth GDI Protects Your Engine

The innovative aspect of Gulf Ultrasynth GDI, which earned Gulf Oil Product of the Year, is its multi-layered approach to engine protection. It confers the following wide range of benefits:

• Deposit Control: GDI engines are prone to building up carbon deposits, especially on intake valves, which can lead to rough idling and loss of power. Gulf Ultrasynth GDI’s advanced detergent technology actively fights deposit build-up, keeping critical engine parts clean.
• Wear Resistance: High engine pressures in GDI systems accelerate wear on moving components, hastening the need for repairs and replacements. Ultrasynth GDI contains anti-wear additives that form a protective film, shielding metal surfaces and extending engine life.
• Thermal Stability: To cope with both the extreme heat of regions like the UAE and the high internal operating temperatures of GDI engines, vehicles need engine oil with enhanced thermal resistance. Gulf Ultrasynth GDI maintains its viscosity under extreme heat, ensuring consistent lubrication.
• Oxidation Control: Oxidation leads to the build-up of sludgy deposits and oil thickening, compromising the lubrication and protection it offers. The higher temperatures and pressures within GDI engines can cause a traditional mineral oil to oxidise and break down more rapidly. In contrast, Gulf Ultrasynth GDI’s robust oxidation stability prevents this deterioration from occurring, allowing for longer oil drain intervals without any sacrifice in performance.

What Are the Benefits of Gulf Ultrasynth GDI 5W-30?

The Gulf Ultrasynth GDI 5W-30 grade is one of the most popular variants within the Gulf Ultrasynth Product of the Year 2025 range, offering a balance of performance and fuel economy tailored to modern vehicles. Its benefits include:

• Fuel Efficiency: Reduced friction properties contribute to lower fuel consumption, a key benefit for motorists looking to minimise running costs.
• Cold Start Protection: Its 5W ‘Winter-viscosity’ rating ensures smooth circulation even in cooler temperatures, reducing wear during start-up- the moment when most engine wear occurs. This comprehensive guide to viscosity ratings covers this topic in greater depth.
• Extended Drain Intervals: Thanks to its resistance to degradation, drivers can enjoy longer oil change intervals, reducing maintenance frequency and servicing costs without sacrificing protection.
• Environmental Compatibility: Cleaner combustion ensures emissions are lower, helping vehicles to meet tighter modern environmental regulations.

Gulf Oil’s Product of the Year award reflects consumer appreciation of not just the technical superiority of Gulf Ultrasynth GDI, but also its alignment with modern expectations of efficiency, reliability, and sustainability.

The selection of Gulf Ultrasynth GDI as Product of the Year 2025 underscores Gulf Oil Middle East’s position as a trusted authority in the automotive lubricants market. Recognised not only for its technical excellence but also for the real-world benefits it delivers to motorists, it sets the standard for what engine oils should achieve. With proven LSPI prevention, deposit control, thermal stability, and fuel-saving properties, it exemplifies Gulf Oil’s century-long mission to combine innovation with reliability.
