There are many myths and questionable advice on the internet. One of them says: when inspections are carried out at gas stations, a 10-litre container is taken as the measuring vessel. Experts fill gasoline or diesel fuel there – checking the underfill within the margin of error and at the same time diagnosing the quality of the fuel.
Since the gas stations are aware of this, they have set up their fuel terminal to deliver the same 10 hours with minimal underfilling. So, for how much fuel you pay, you get so much of it in this case.
Expert opinion
Alexey Revinexpert “Behind the wheel”:
— In my opinion, the advice is not very helpful. First, you will have to drive to the gas station quite often, and if the column is not in your parking lot in the courtyard of the house or near work, then these are extra hundreds of meters or even miles of unnecessary miles and lost time . Secondly, you often have to unscrew the cap of the gas tank, allowing air to enter that contains moisture that condenses on the walls of the tank.
Instead of this method, I can advise you to do it differently.
If you remember approximately how much gasoline is in the tank when the fuel gauge is in the last quarter, order not litres, but the quantity. For example, for 1500 rubles. So that the tank is filled in the range of the upper quarter of the indicator. So you can more easily pay in cash or have a clear idea of the fuel costs on a bank card.
If you want to fill up, I still don’t recommend telling the employee at the pump. The fact is that he literally responds to the words “full tank” and strives to pour fuel under the cut on the neck. At the same time, the filling nozzle clicks repeatedly, shutting off the supply. Fuel almost does not flow, but the meter diligently backwashes liters and rubles. I advise you not to tell the gas station employee “full tank”, and “full, until the first cut-off.” This is when the smart nozzle system itself automatically shuts off the fuel supply and senses that splashes and foam are nearby.
