Once more common (not least because the supply nozzles and hoses were the same size), filling up the car with the wrong fuel hasn't fully become a thing of the past..
This is because the smaller filling nozzle dimension of a car with a gasoline engine and the larger hose width of a car with a diesel engine make it almost impossible to fill the tank of a gasoline car with diesel, the same is not the case. .
Now, if you are one of those people who frequently switch between a petrol car and a diesel one, and you are unlucky enough to fill up with the wrong fuel, do you know what to expect?
In this article we will try to dispel myths and explain to you all the problems your car can have if you force it to a “forced” diet change.
Filling a Diesel Car with Gasoline
Imagine this scenario: you arrive at the gas station in your Diesel car, make a mistake and fill up with petrol. In this scenario you have two hypotheses: either started or not started the car.Subscribe to our newsletter
If you realized the error and you didn't start the car — in fact, switching on the ignition is already harmful — all you have to do is call the trailer so that the tank can be emptied in the workshop.
If you didn't realize the error and, unfortunately, you turned on the ignition or started the engine , the bill will be higher. And even if you realized the error in good time and resorted to the trick of filling up what was missing again with diesel and starting the engine, it won't avoid problems, especially in modern diesel engines.
In this case, the best thing to do is to turn off the engine as soon as possible and call roadside assistance.
After that, get ready for a repair that will involve cleaning the fuel supply circuit, replacing the diesel filter and also for the possibility that both the injection pump and the injectors are broken due to this new and undesirable diet.
Diesel in a gasoline engine
Nowadays, due to the size of the filling nozzle on gasoline cars, it will be more difficult to put diesel in a gasoline car — difficult, but not impossible.
In the event of this happening and you have noticed the error in time, where you only put a little diesel, we have good news. If you top up the rest of the tank with gasoline, and it is mostly filled with gasoline, the problem can be solved without having to visit the workshop. The probability is that, when running, you will notice a lower engine performance.
However, if the proportion of diesel is greater than that of gasoline in the tank, do not start the engine. You'll have to visit the mechanic so he can empty the tank.
If you have started the engine, with most of the fuel in the diesel tank, then the best thing is to hope that the wrong fuel has not passed through the catalytic converter without having been burned. If this is confirmed, prepare yourself for a very expensive repair.
