A WAI may be part of the future mods installed on this car.
Today was a pretty good run as well. It was 3F out (yay). I got a full 35 minutes in with the block heater which put the coolant at just over 100F when I started it up. I got to work with just a hair under 42 mpg on the MFD, and 40mpg on the SG.
Aaaand, I filled up for the first time last night. Considering the really cold temps, a lot of time spent idling for the heater core / heating issues I've been having it was a very respectable 42.1 mpg! I'm pretty darn happy with that.
