Odd fuel-saving strategies abound and can be effective in some situations. However, having a tank in reserve is definitely something that will not help you at all with the economy. On the contrary, this practice can cause even greater losses.

What’s wrong with driving a tank in reserve?

All cars have an amount of fuel that is considered an emergency reserve. In practice, it is a sign that the liquid has run out and it is necessary to fill it up so that it does not suffer from a dry bowl.

The common volume of fuel in the reserve is usually about 10 to 15% of the total held in the tank. So, you should not operate the car this way, because it was not made for it. One of the problems is with the fuel pump.

The fuel pump is responsible for absorbing gasoline tank To take them to syringes, where they are inserted into cylinders to be incinerated. However, when the fuel level is too low, air bubbles form and the pump has to work harder. It’s the same thing that happens when we drink soda through a straw: when the liquid runs out, we have to work harder to get the drink into our mouth.

All the effort the device makes to suck gasoline from the tank into the reserve can cause damage and reduce the useful life of the tool. Changing the pump can be something over R$400 in popular cars, for example.

Waste accumulates at the bottom and causes problems

Pump wear isn’t the only setback caused by the bad habit of riding many miles with a nearly empty tank. When there is little fuel left, it is more likely that the deposits that accumulate at the bottom of the tank will clog the filter and injectors, affecting their operation. Replacing these parts is not cheap.

Walking in the reserve spends more

Finally, know that leaving the space until it’s full only after the spare lamp lights up will make you spend more. The air in the tank accelerates the evaporation of the fuel itself. The daily variance is quite low, but if it accumulates with a habit that spans days, months, and years, the effect can be significant.
