21.2 litres / 100 km (a measly 13 mpg) – that's the fuel consumption quoted by Rolls-Royce in the city for the Wraith coupe and its massive 21.9-gallon (83-litre) fuel tank. That seems just about right considering the opulent two-door vehicle weighs a hefty 2,360 kilograms (5,203 pounds) and is powered by a massive V12 6.6-litre engine equipped with a pair of turbochargers.

The owner of Goodwood's posh gas-guzzler discovered his car is thirsty in the worst way possible by running out of fuel in a crowded intersection in Mamaia, Romania. Blame it on a defective fuel gauge (highly unlikely) or the driver's inattentiveness, it's without a shadow of a doubt an embarrassing experience, especially when you're coming out of an expensive car such as a Rolls-Royce.

With just about everyone owning a smartphone these days, it goes without saying his mishap was all caught on camera, from various angles at that. He made not just the local news, but basically all the main news channels in Romania, with the car's number plate appearing in the footage. Running out of fuel just ahead of a busy roundabout caught the attention of other drivers, and some of them didn't hesitate to shoot videos.

Towards the end of the clip, a friend (or simply another driver who noticed his predicament and decided to help) comes to the rescue with a small plastic can filled with petrol. People on social media are saying the apparently green fluid is AdBlue rather than petrol, but we'll remind those people there's no such thing as a diesel Rolls-Royce Wraith that would need the liquid used to reduce the nitrous oxide emissions. The container is green and it's pretty obvious the petrol in it has the normal colour.

Taking into account how much fuel the lavish coupe needs, the petrol poured into the tank was likely just enough to reach the nearby petrol station. Carrying fuel in a plastic container is a different story as it could be quite dangerous, especially on a hot summer day as was the case here. That appears to be a plastic can from washer fluid, so it's certainly not suitable to transport fuel.
