Among the details that frustrate drivers is a hand that shows how much fuel is left in the tank, as well as a digital indication of the remaining miles.

However, the number of kilometers we can cover is seldom accurate, because exact calibration is almost impossible, writes ekapija. According to the American Automobile Association (AAA), accuracy varies more over short distances because the sensors and software that control the remaining range of indicators are very sensitive to inconsistent accelerations.

According to AAA, 74% of drivers use a screen that indicates the remaining miles when deciding when to go for fuel. Coincidentally or not, these drivers can take unnecessary risks by relying only on the readings of the trip computer.

The U.S. organization recommends drivers get fuel if the hand indicates that the remaining quarter of the tank is available. This is of course the most rational advice, because driving a car when it turns ‘red’ is definitely not good, as petrol fumes can lead to wear and tear and can eventually damage the fuel pumps.

The engine also does not like the fumes involved, and there is a problem with dirt in the tank.

Driving on the “reserve” is the best way to locate the sludge that has accumulated in the bottom of the tank in the fuel injection system and the engine. These substances come from filling stations where the petrol level in the tanks is near the end.

And the easiest way to notice at the gas station that the last supply of fuel is being thrown out of the tank is to analyze the fuel flow. If the petrol flows more slowly than usual, it is very likely that unwanted substances will soon be found in the vehicle’s tank.

Measurements on the dynamometer, on which the selected vehicles simulated different driving scenarios, showed that the consumption of the tested vehicles shows an average error of 2.3% compared to the values ​​on the dynamometer.

Faults in individual vehicles varied widely, from minus 6.4% to plus 2.8%. Specifically, in the first car tested, the economy was overestimated by 6.4%, while in the last one it was underestimated by 2.8%.
