Out of fuel — and why diesel is the harder case

With petrol, topping up is usually enough. With diesel the system often has to be bled.

Symptoms

  • The engine loses power and stops
  • The car runs in surges
  • The gauge has been on red for miles
  • The starter cranks but will not fire

Do not keep turning the key. The fuel pump is cooled by the fuel itself; cranking it dry destroys it, and a new pump costs many times more than a tank of fuel.

Petrol: topping up is usually enough and the car starts after a few attempts.

Diesel: air enters the system and it has to be bled, sometimes only at a garage. A jerry can does not always solve it on the spot.

Do not put the wrong fuel in while rushing. Petrol in a diesel engine is a far more expensive mistake than an empty tank — in that case do not start the engine at all.

When you need a tow: a diesel that will not start after refuelling, wrong fuel, or you have stopped on a motorway. We take the car to a petrol station or a garage.
