I agree that the effort it took to put in the system that they did, they could have given it a full gauge. Does that require "some work arounds" well maybe. I am not sure if the issue is not a full gauge or the algorithym not being correct regardless of whether you can see the amount that it indicates. I too have seen the issues you mention about the rate of burn not being consistent. I just periodically top it off. I guess that is my work around. I have other equipment that burns DEF so I just empty my partial containers in my pickups and I always have it with me. So for me it is just a habit I have developed. Periodically topping it at every other fill up would probably be similar. DEF itself is also ridiculous, but they don't run without it so...
