What Happens if You Put Diesel in a Gasoline Car or Vice Versa?

Surely you know of at least one case in which a driver accidentally put other fuel than the one he needed in the car's tank. Maybe when he changed the car, he gave it to his wife, there are plenty of reasons, but it certainly happens from time to time. What can we do in this situation?

After realizing that human error is quite high, the manufacturers modified the fuel supply port of the cars. Specifically, gasoline cars began to be built with a narrower nozzle, and gasoline-powered gasoline guns became thicker.

This is so that you can no longer "stick" the diesel gun in the mouth of a gasoline car. But conversely, that is, to refuel a diesel car with gasoline, is perfectly possible, because the barrel of the pistol is narrow and the feed mouth is larger.

The manufacturers have done a few more things. Namely, how you open the tank door is a big sticker that tells you what kind of fuel to put. And on some models, right on the dashboard, next to the fuel level indicator, write if you need to put diesel or gasoline to subconsciously imprint exactly what you need to put. Even so, owning one is still beyond the reach of the average person.

What do we do if we put diesel in the gas tank or vice versa? Nothing may happen, or chaos may break out. It all depends on how much we put in the tank.

Quite rare are the cases in which the man with the car on diesel fills up with gasoline. If you put more than 10 liters of the wrong fuel, you must empty the tank. And you can do this in two ways: either with a hose, through the supply port, as in the past, or by removing a supply hose from the injector ramp. The first solution is good, but the hose does not always reach the bottom of the tank due to the crooked path.

The second option generally used by those who are good at mechanics is to take out an injector supply hose, extend it with another hose, and put it in a canister. After that, turn on the ignition and the pump will remove all the fuel on its own.

If we notice the mistake in time, before starting the engine, it's okay. If not, we will set off and when the car stops and starts to roll, as if it has square wheels, just looking at the gas station receipt we will realize the mistake made. If we realize in time, we push the car to a quieter place and take the fuel out of the canisters, then fill the tank with what is needed. If we left and our engine stopped, it's harder, because then we have to get the fuel out and refuel, but we'll be further away from the gas station. After that, the engine will start, but a little harder, and for a while, it will go into the nests.

What do we do if we start refueling, but we quickly remember that the car is on diesel? As long as I only put in a maximum of 10 liters of the wrong fuel, it's no problem. But we have to fill the tank with it properly so that the wrong liquid is diluted. We may not feel anything while driving, but there is a good chance we notice that the engine is shaking at idle and that when we accelerate it stops.

CAREFUL! Regardless of the situation, until the engine starts running and round, as a quarter of the tank empties, we stop at the gas station and refill with what is needed, so that the wrong gasoline or diesel is further diluted.

Otherwise, other parts should not break. No injectors, no spark plugs, or whatever. In the worst case, the diesel engine will not start, but it will start when it is pumped and the diesel is clean. So, it's no tragedy if we're in love or with our heads in the clouds and we get our hands on the wrong gun at the pump when refueling.
