They are constantly refueling on a Giger, everything is fine. Talk about not topping up is groundless , we use a propanobutane mixture , propane burns better but the efficiency is lower , butane efficiency is higher , it all depends on the quality of the mixture . The operators work as expected. The speakers are sealed . I am an ordinary driver and my opinion is not biased.
There is a 42-liter tank in the car, 42 liters of Gas are filled in all gas stations, but At least 45 liters of Gas are filled in the Giger gas station, and how do they do it?
