Re: def usage
Mine wasn't full (forgot to check) when I picked it up the Saturday before Christmas. 14 miles on the odometer.
I filled it with DEF at 2200 miles, about $17 at the pump.
It now has 3200 miles, and as I pulled into my garage tonight after work it showed about 85% full.
In this cold (Maryland), my EVIC and hand-calculated MPG is around 24.
