Full Answer

When the pump is damaged, metal particles remain in the fuel posing further issues to the rest of the fuel system. Some fuel systems can be damaged with the components in petrol. When petrol goes deeper into the system, it becomes more expensive to make repairs. Therefore, when petrol is accidentally filled in a diesel engine, the car should not be started. It is important to carry out a full drain, before starting the car.

  • Q:

    What is the difference between petrol and diesel engines?

    A:

    A petrol, or gasoline, engine is very similar to a diesel engine but is generally lighter and uses a spark ignition system rather than the diesel's compression ignition system. Diesel engines are exposed to greater pressures and must be built more heavily than petrol engines for the same capacity. Both petrol and diesel are refined crude oil products, but diesel is less refined and is very similar to heating oil.
