I was trying to wait until I'd burned at least one full tank of gas following the update, so here goes. Prior to the update I was regularly getting 46-48 mpg averages, and now I'm hovering between 42-44 at most on the same basic trips as before. Nothing has changed in my driving habits as before, not using heat/ other power sources, etc. Ford engineers advised that it takes 30 days to "break in" the new update before it stabilizes, but I don't like the direction this is headed. Anyone else observing the same? I'm not saying I'm dissatisfied with FE overall versus my Subaru, but I thought this update was supposed to IMPROVE FE. What am I missing?
