Our 2013 Civic was stuck in city loops averaging 28.53 mpg for the first 2,500 miles. Now with more miles accumulating we're starting to see the 39 mpg highway rating in our recordings. The Civic's overall mileage average increased 1.75 mpg since the last update 1,200 miles ago. All fill-ups tallied in above 30 mpg instead of the mid-to-high 20s from earlier tanks.

A road trip also helped bump the BRZ’s average .5 mpg with a strong tailwind shoving the light BRZ up to a 36 mpg average over 160 miles traveling from central Wisconsin to the Chicago suburbs. That tank also extended the longest-recorded range to 338 miles and almost touched the previously recorded best tank mpg (30.80 mpg) with a 30.78 mpg average. So close.
