For GCC-spec Audi Q5 models widely available in the UAE, such as the 2.0 TFSI or 45 TFSI, the manufacturer's official recommendation is to use Special 95 (95 RON) petrol. This is clearly stated in the owner's manual and on the fuel filler cap of vehicles sold here. While Super 98 (98 RON) is a higher-octane fuel, it is not a requirement for standard models and is primarily beneficial for high-performance variants like the SQ5 or in extreme conditions like consistent high-speed desert driving in summer temperatures above 45°C.
The practical difference for a typical UAE driver commuting on Sheikh Zayed Road or facing Dubai-Sharjah traffic lies in engine response and potential long-term maintenance, not in mandatory usage. Based on fuel efficiency data from the UAE Ministry of Energy and Infrastructure and total cost of ownership (TCO) models, the choice impacts operating costs. For a 2023 Audi Q5 45 TFSI, the annual fuel cost difference can be calculated.
| Fuel Type | Avg. Fuel Economy (City/Highway) | Est. Annual Cost (20,000 km) |
|---|
| Special 95 | 10.2 km/l | ~9,800 AED |
| Super 98 | 10.5 km/l | ~10,450 AED |
- Fuel economy: Super 98 may offer a slight efficiency gain of 2-4% in real-world UAE driving with prolonged A/C use, as noted in 2023 vehicle testing reports aligned with GSO (Gulf Standardization Organization) standards.
- Cost per km: The fuel cost difference is approximately 0.03 AED/km, making Super 98 about 6-7% more expensive to run annually, based on average UAE pump prices from the Central Bank of the UAE's commodity reports.
- Long-term value: Using the recommended Special 95 does not void warranty and ensures optimal performance for the engine's ECU mapping. The marginal performance gain from Super 98 in a standard Q5 does not justify the higher annual fuel expense for most owners, considering the vehicle's annual depreciation, which is the largest part of TCO in the UAE's fast-paced car market.
