Mine always tells me the percentage that is left, usually around 37%. Other than that it's says full. I bought the VW AdBlue off Amazon to get the cool unspillable bottle. It's only half gallon, so it would need to be refilled 4 times to get the 2.5 gallons in that the 37% indicates. Lot better than spilling it all over the side of your car lugging the 2.5 gallons jug around by that tiny hose.
