I have been wondering a while if the practice of slowly filling up the propane gas tanks actually gives one more gas as opposed to fillin git up rapidly.
To test this theory I have been consistently filling up my tank at one place in Santiago. I typically wait until the tank is completely empty and then fill it up. My averages to fill up the tank at the normal speed is around 16.3 gallons.
On Sunday on our normal trip to Moca, even though the tank wasn't empty I decided to fill it up and told them to do it as fast as possible. I estimate that there was at least 0.5 gallons left in the tank minimum. They proceeded to fill it up and I stopped them at 17.0 gallons when I'm pretty certain it would have gone to 17.5 gallons. The temperature was pretty hot as it was almost 12 noon.
From this experiment, it appears that the slower that the tank is filled up, the more gas one gets for the same price. I believe what is happening here is that the very slow or very fast flowrates are at the extreme of the meter's efficiency, thus the discrepancy.
