95 subie imp awd wagon, 1.8L:
I usually get 27.5 mpg combined and 29 hwy, plus or minus 1.
This time, I got 24.3 for mostly short city trips, some hwy (averaged over half a tank of gas), and I'm like [censored] happend?!! Does the way more frigid than usual weather matter that much for milage that it knocks of 2 or 3 mpg?? It's been in the 20s when the normal pdx weather is like 40s usually.
Or maybe I forgot to reset the trip odo, and the half tank was too short to sample over.
