Some motorists continue to fill their tank, even after hearing the audible signal, or “click”, indicating the maximum capacity. But beware, this bad habit can be dangerous.

VSis tempting. As La Voix du Nord explains, after hours of waiting in queues to access petrol stations, motorists want to insist after hearing the famous little “click” which indicates that the vehicle’s tank is full. If we could add one or two liters like that… Except that in fact, it is not exact.


Questioned by Autoplus, managing director of the British company Select Car Leasing, Graham Conway had thus explained that this click is used precisely not to fill its tank to the brim. Thus even when the signal is ignored, the excess fuel is evacuated mechanically either to the pump or to the road. Conclusion: it is neither profitable (we will pay for gasoline that is not in the tank), nor safe because the road becomes slippery and the fuel is wasted.

In the vehicle, adds Graham Conway, “this can propel liquid fuel into the pipes and deteriorate the vapor recovery system”, especially for motorcyclists, he indicates.

The French government, under fire from opposition critics, called on Tuesday for the lifting “without delay” of the blockages of fuel depots, threatening to “intervene” to unblock them, but the strikers did not give in and renewed movement, both at TotalEnergies and at Esso-ExxonMobil.
