There are all sorts of news and answers about this but here is the truth to how the fuel burns and what their actual properties are. If you put diesel fuel into a petrol car the engine will run on lower power, maybe even pushing the car in to the engine maintenance mode and you'll see lots of smoke. This is not a problem as the fuel can be drained from the tank and run through the engine and the right fuel put back in and the car is on it's way again without any long term issues. The car should run normally ongoing.
Putting petrol in a diesel car will not lubricate the injector pump and also the injectors, this then causes the all parts to heat up and expand over time and then stick to each other potentially causing thousands of pounds worth damage depending on the car type.
Again, do not be put off with this as this example is if the petrol had been run through the engine for a while, in 99% of cases where we provide fuel drain recovery, the customer has either realised the mistake and pushed the car to the side of the forecourt, or they have not been driving the car long enough for the car to have this issue.
Another reason not to worry is that there will usually be some fuel already in the tank which will aid the lubrication in the near future after a misfuel, but the warning signs will be the car jumping and acceleration will jump too.
The parts of the engine that can be damaged through putting petrol in a diesel engine are
So, no misfuel is good the car and both can be drained without any problem, but of the two we would say "Putting petrol in a diesel car is much more detrimental than putting diesel in a petrol car"
We recommend if you have put the wrong fuel in your car to do the following 3 steps
DO NOT TURN THE IGNITION ON
PUSH THE CAR TO A SAFE PLACE
