What happens if you put Diesel in a Petrol Car?​

Putting diesel in petrol car, or even diesel in a petrol hybrid is a fairly simple mistake, but if you don’t take care of it properly and right away, it can cause serious problems.  Even starting your cars engine can cause damaged. Perhaps many years ago the advice to ‘run it until the bad fuel is used up’ might have been helpful, but attempting that with even a slight diesel fuel contamination in a modern car is just asking for a breakdown at an even more inconvenient time and place.

If you put diesel into a petrol car, do not start the engine because this will contaminate the fuel system. Putting diesel in a petrol engine is particularly troublesome, as diesel fuel is much denser than petrol. The thick, comparatively gummy diesel can clog your engines fuel injectors, and can be almost impossible to clear – unless done with the right equipment and the right training.  

It’s important to act quickly. The vehicle’s fuel tank requires draining (and the contaminated fuel disposed of safely). Then you need your entire fuel system flushed before you can get on with your day.
