Upset to the core! This is the first time this has happened. I filled the tank with 10 liters - the arrow rose by a maximum of 2!!! I drove up to ask how this could be - they sent me to check the sensors in the car. The car is new, but the sensors have been checked. I had to go to another one and refuel again at 10. The arrow rose as expected. The mood was ruined for the whole day. I will not come anymore ((( I will write wherever I can and tell everyone about such an impudent underflow!
