The only gas station where the staff was able to blow out a gas cylinder with a volume of 38 liters as much as 41.5 liters of gas, while smiling cordially and proving that the cylinder had swollen dramatically. Of course, the money was not returned, there was even an offer to refuel the cylinder further. I wonder to what extent they could.
At all other gas stations, 38 liters are blowing according to the technical characteristics.
