Putting diesel in a gas tank is a mistake that can make when refueling at a service station and that can bring a significant expense.
Yes, we know, it is one of the worst nightmares for any driver, because it can be one of the most terrible mistakes we can make when we are going to refuel. Wrong fuel and throwing the one that does not apply to our car can lead to a serious problem. Whether it is a minor problem or a serious breakdown is something that will depend on several factors, so let’s review what happens when a diesel car filled with a gas car.
We already know that a diesel engine works differently than a gasoline engine does. Also, there are important differences between gasoline and diesel, which can cause serious problems in engines that not prepared for that type of fuel. In another article, we have already talked about what happens when a diesel-powered car fed with gasoline, and today, we will see what happens in the opposite case.
The service stations prepared to avoid these errors since the nozzles of the two fuels are different. In the case of diesel, this is thicker than gasoline, so just by trying to use the wrong hose, we can realize. But it may be that the car is older, and the tank does not adapt to the different types of hose. And the time comes, and we put a considerable amount of diesel in the gas tank.
How diesel damages a gasoline car
Unlike the diesel car in which gasoline has added, a small amount of diesel may not cause major damage. If the amount is more or less than a quarter of a deposit, the engine will start without problems and circulate. But for the damages to be minimal, you have to think of very, very small amounts. In this case, the car will start and can circulate, although it will do it irregularly and releasing an abundant white smoke.
If the amount is considerable, you have to think that the damage will occur yes or yes. If we realize while refueling, it is better not to start the car. We must notify those responsible for the service station and take the car to a corner where it does not disturb the rest of the vehicles. And, immediately, the insurance must be notified so that the crane can come and take it to the workshop.
Before filling the fuel tank with diesel, you must avoid starting the engine and calling the roadside service. In the workshop, you will empty the tank and clean it. If the car has not started, the diesel will not have reached the engine, and the problem will end there. Then the tank will be filled with about 5 liters and let this fuel consumed. When it is about to empty, the tank will be filled and circulated until it consumes, more or less, a quarter of the deposit. Then it will be filled again, and in theory, here the problem ends.
But if the car has run on diesel, the problems multiply, and the repair costs too. If the car has been running several kilometers, the diesel will have passed to the engine circuit and will have dirtied elements such as injectors. This result is already a problem because they will have to clean, and this is a considerable expense. And it can be worse because they may have been damaged and should be changed. All this added because you will have to clean the entire engine and check that there is nothing more damaged.
The catalyst can also be damaged, and if so, it must be changed as well. A small (although expensive) headache can become a real nightmare if we don’t look when refueling. Like when we drive, we must be very attentive at the time of refueling, because a mistake that might seem small can leave us without a car for a while, not to mention the bulky bill that we will have to pay.
