My typical weekly drive is less than 2.5miles one way, my engine never gets fully warmed up even with remote start. Quite often my 1LT DIC is reading less than 10mpg with an average speed I could beat walking.
Fighting those numbers above I still average 29mpg all winter and 37mpg all summer(pump calculated).
Another 8 weeks and we can start getting our averages back up.. Any time I see my average in the 20's -30's it almost makes me cry,, My average since August is almost down to 47 .. But , our mileage would worse in any other car
