I do read the gage on the side of the tank and make notes on my receipt and in my spreadsheet.
Sometimes the weather is cold, yes, but not always. As I mentioned, I like to keep things ready to go.
I have always mistrusted fuel gages and speedometers, so I look for ways to validate readings.
With an engineering mindset, I observe evidence and rely on instruments. Also with a metrology background, accuracy of those instruments is paramount.
Fuel tanks are not rocket science. Wait until the gauge on the wall,not on the tank, drops to 1/4 tank left, and go get a refill. Saves diesel and wear and tear on your C class.
Another option is to buy a spare 5 gallon propane tank for back up if your main tank goes empty.
