In the UAE, idling a car with the air conditioning on for one hour typically consumes between 0.8 to 1.2 litres of fuel, but this can easily exceed 1.5 litres for larger GCC-spec SUVs during our summer. For context, a Toyota Land Cruiser 5.7L V8 idling in 45°C heat can use approximately 1.8 litres per hour, which equates to an effective fuel economy of about 4.2 km/l during that idle period—significantly worse than its highway driving figure. In contrast, a common sedan like the Toyota Corolla 1.6L might use around 0.8 litres per hour, translating to an effective 12.5 km/l while stationary. The direct cost in AED is substantial; at a price of 3.1 AED/l for Special 95 (based on March 2024 UAE fuel prices), idling a Patrol for an hour costs about 5.6 AED in fuel alone. This doesn't include the accelerated wear on components like the battery and starter motor, which increases the total cost of ownership. Prolonged idling is common during Dubai-Sharjah rush-hour traffic or while waiting outside schools, making it a significant but often overlooked expense. RTA Dubai actively campaigns to reduce idling to improve air quality, while data from the UAE Ministry of Energy and Infrastructure highlights the national fuel waste from unnecessary vehicle idling. Using Super 98 does not significantly reduce idle consumption. The most effective way to save is to avoid idling for more than 30 seconds; modern cars with auto start-stop, like many hybrid Toyota Camrys in UAE fleets, are designed for this exact scenario. Regular AC system servicing, especially before summer, can reduce compressor load and save up to 15% in fuel during idling.
