What happens mixing petrol with diesel?
you have two choices! drain the tank of the contaminated fuel recommended but you won’t do or top up with diesel and take a chance of damage the engine will run fine and probably not get damaged its self but the part that gets damaged is the injector pump this is because of the very tight tolerences of the parts inside the pump which rely on the diesel for lubrication which the petrol reduces causing the parts in the pump to wear out prematurely you can see if there has been damage by removing the fuel filter and in the bottom of the filter housing you will see tiny pieces of shiny metal that has come from inside the injector pump thats the risk the choice is yours!
