What should you do if you accidentally put petrol in your diesel vehicle?
If you have put petrol in a diesel vehicle and you have started the engine, switch the engine off immediately and get the vehicle towed to a licensed repairer to have the fuel tank and fuel system drained and checked for any engine damage that may have occurred. If you have put petrol into a diesel vehicle and have NOT started it, do not turn on the ignition or start the vehicle as this will prime the system and possibly increase the cost of rectifying the problem. Get the vehicle towed to a licensed repairer to be drained and checked. If the vehicle is not started or primed, there is less chance of damage.
