Some updates:
Moved to downtown Burlington, so most of my trips lately are <5 miles, and the weather has been between 0 and 20F for the most part, resulting in pretty absurdly bad mileage. I'm putting far fewer miles on the car in total too, so it's looking like weeks, possibly even months between fillups.
New project though! I'm going to do some upgrades to the DC-DC converter to improve its efficiency.
