Running a diesel car on petrol can cause significant damage almost immediately. Engine damage can occur within minutes of running, as petrol acts as a solvent, reducing lubrication and damaging parts like the fuel pump and injectors. It's crucial to turn off the engine and not start the car if you realize the mistake before causing extensive damage. The best course of action is to have the vehicle towed to a service station to drain and clean the fuel system.
