Both fuel gauges (screen and needle) are telling me that I am losing 1 mile every 20-30 seconds. I have found no fuel leaks, no gas fumes while driving, no smoke of any kind, and it is driving fine. This occured after I completely refueled my tank.

You could have a stuck EVAP purge valve, but can I ask if the gas is really being burnt, can you see black smoke out the rear of the exhaust while driving, also do you need to fill your tank much more often? I am trying to figure out if it is a gauge or engine consumption use.
