Why does my 20lb. propane tank not empty all the way? When its about half empty I run out of gas. What gives?
Answers:
Perhaps you should view the tank as "half full"?
Other answers:
It may not be pressurized correctly. Might be time for a new tank.

I suspect it is the regulator. If the tank still has liquid in it and its not really cold the tank should provide the gas for a grill. Check the regulator on the grill and the valve on the tank.
