Filling the entire tank of our car is a very common practice for many people, but can bring with it several risks. This is what the mechanic has warned on his social networks Juan Joséknown on TitkTok for generating all kinds of content with advice on how to take care of our vehicle.
In his latest video, he details that filling the entire tank can have serious consequences and that these can be different whether the vehicle is gasoline or diesel. In fact, he says that the former are the most sensitive to this sensation.
“The gasoline one incorporates a canister valve that, when the tank is too full, part of that fuel in liquid form will pass to that valve that It usually has a carbon filter that usually corrupts it”, assures the expert.
Another factor that influences how our vehicle works with the entire tank is the temperature of the place we live or drive through: “It is not the same in a very cold winter area in the north of Germany than, for example, in an area in the south of Spain where it is much warmer. The evaporation of the fuel will react in different ways.”
Despite these conditions, Juan José assures that filling the tank to the top can generally cause problems for all vehicles because a tank actually has several vents, pressure valves and its fuel flow: “If we have it very loaded with a quantity of liquid, what will happen is that when we have evaporation, movement, cooling or condensation processes, “All of that is going to be affected by that volume, which is going to be more pressurized.”
For all these reasons, it recommends that It is best to have the deposit at three quarters and, at least, a quarter. “That would be ideal to maintain the perfect level in your fuel tank,” says the mechanic, who, despite everything, admits that he sometimes fills it completely himself, for example, when he goes on vacation or at the beginning of the month. “Although it is not what I would recommend,” he concludes in the video.
