Putting the wrong fuel in your car can have serious consequences. Petrol and diesel have different properties and combustion characteristics. Petrol has a higher flashpoint and requires high compression to ignite. On the other hand, diesel is a less volatile fuel that requires compression and heat for ignition. If petrol is put in a diesel car, the engine may not be able to recognize the contaminated fuel and may suffer damage. Similarly, if diesel is put in a petrol car, the engine may misfire and the fuel system may be damaged. In both cases, it is important to drain the tank and clean the fuel system to prevent further damage.

It is important to be aware of the risks associated with putting the wrong fuel in your car. If you have accidentally put petrol in a diesel car or diesel in a petrol car, it is recommended to not start the engine and seek professional help. Draining the tank and cleaning the fuel system should be done by a qualified mechanic to ensure the proper functioning of the engine and fuel system.
