Errors when refuelling: Drivers not only have to pay attention to the fuel nozzle - the temperatures can also lead to problems when refueling.
Fuel prices are still high, so drivers should avoid common mistakes to save money.
If it's relatively cheap at the pump, as much as possible should go into the tank.
But when filling, a very specific mistake happens again and again.
The “click” on the fuel nozzle is crucial, as
echo24.de
reports.
And experts see a second important detail.
Drivers should always keep an eye on the current temperatures when refueling.
Otherwise, problems can arise, especially in the summer months.
Correct refueling: Motorists should stick to the “click”.
Anyone who has the pump nozzle hanging in the tank on the car knows the procedure: When the tank is full, the process stops automatically - if you have activated the automatic switch-off.
A loud "click" can be heard.
But is the petrol tank in the vehicle actually full?
Surely you can press the fuel nozzle once or twice?
no
Experts generally advise against adding fuel after the "click".
According to
Auto-Bild
, this can cause the tank to overflow.
As the TÜV Thüringen writes, automatic switch-offs are
“set in such a way that there is always at least one liter of air in the tank”
.
Overflowing fuel can only cause limited damage to the vehicle.
However, experts are critical of the fact that the fuel gets into the environment in this way or comes into contact with the skin.
Drivers who have come into contact with it should immediately wash the affected area with plenty of soap and water.
Skin irritation may occur.
Excessive heat can become a problem for motorists when refueling
For the experts at TÜV Thüringen, extreme heat in the summer months can also pose a problem when refueling.
If you don't pay attention to the "click" of the automatic switch-off at temperatures of around 30 degrees, you are at risk of a problem.
Liquids such as petrol or diesel expand and
"occupy a 2 percent larger volume if the temperature rises by 20 degrees"

It goes on to say:
"If there is 50 liters of petrol in a car tank at 10°C, that is already 51 liters at 30°C"
.
If you continue to fill up with fuel after the "click" of the fuel nozzle, you must expect the tank to overflow.
Achmed Leser, accident and damage expert from TÜV Thüringen, also sees the situation as problematic: "Leaking petrol not only damages the vehicle and your wallet, but also contaminates the ground and the water." In the TÜV report he also explains: "The worst case comes there was a vehicle fire.”
