THe old saying is the least accurate gauge made is a fuel gauge..
Seriously on Propane the "It reads full till it's empty" applies to inline pressure gauges used for luggable tanks. If you have a motor home you have a float type gauge and the dial on the outside is very accurate. Well. Very "repeatable" let's put it that way.. you may have more, or less than you think but when it says for example Half full.. Well you have x gallons. and the next time it says half full you have exactly x gallons, not one pint more or less.
The Fridge SIPS gas. and I mean SIPS .. Not like the stove which eats the gas or the Water heater or furnace with GOBBLE IT IN MASSIVE AMOUNTS.. The Fridge just sips.
