Hard underflow of gas !!! I have a car with a factory HBO of the 5th generation, the on-board computer shows how much gas is consumed. At normal gas stations, the discrepancy is 7-8 % when refueling from full to full. What was my surprise when BC showed 15.7 liters spent and they filled 21.54 liters - 37 % more!!! I called the hotline and was invited to check the column at 16:00. We showed them how accurate their filling was , and conducted a brief review . The next morning I stop by again, the BC shows 10.5 liters spent, 13.15 liters are poured , 25% more. I call the hotline, I say goodbye, I am no longer your client, with such deception. The next day I stop at another gas station of the Kharkiv network, and oh, a miracle, the BC shows 16.2 liters spent, 17.3 liters are refueled, a discrepancy of 7% !!!
P.S It's up to you to refuel or not, I decided everything for myself, miracles do not happen, there were no sudden temperature changes.
All refueling was carried out in the morning at a temperature of +25.
