Question { Ford, 12435 }

can we start the diesel engine with petrol and petrol engine
with diesel?(just start not run)

Answer

due to some schmucks, who forgot that they had petrol engine and fueled them selves with diesel, that car was fine till the petrol completely emptied and when the diesel kicked in the car was having all types of horrible knocking bumps

this experiment was done by a show "Fifth Gear" and the result was petrol car worked in diesel and diesel car worked in petrol, however the latter case experienced more trouble in driving

to answer your question, yes it is possible to interchange the fuel, but don't expect it to be smooth
