Damage from pouring petrol in diesel car

Pouring petrol in diesel car can hurt your car way more than the other way around. Diesel engines and fuel pump uses diesel itself to lubricate its parts to a great degree, whereas petrol is a poor lubricant. This causes the metal parts in the engine and fuel pump to work under greater resistance that chips off metal from the parts and running it inside the fuel lines can clog your fuel lines and ultimately damage your engine.

Also putting petrol in a diesel car is way more common and easier as the diesel nozzles are bigger in size than the petrol ones. So, petrol nozzles easily fit inside a diesel tank.

Although pouring petrol in a diesel car is not that common just because the diesel nozzle does not really fit in most of the petrol, but still some individuals manage to pour it in their car accidentally. It is also not as catastrophic as petrol in a diesel car, but it can still damage the engine. Diesel can clog up on the spark plugs causing misfiring and making the car emit smoke due to the unburnt diesel inside. Your petrol engine may eventually stall on diesel completely.

Repairs

In case of running the engine on petrol for a considerable amount of time, you may need to replace your fuel pump, fuel lines and even engine repairs depending upon the degree of damage done.
