2018 crv awd bad mileage
 

16-20 mpg. 1300 mi. Easy driving.

Gasoline, automatic transmission, SUV body, not the best combo for good fuel economy.

I had one of these as a courtesy car and, according to the dashboard display, I was getting 45 mpg UK.

That is a bit low but still in the break in period, tire PSI okay ?

Tires will have a thousand or two more miles of wear on them before taking the EPA tests.

Do you use your right or left foot on the brake? I've seen people driving around town that must be using their left foot on the brake, which is a definite no, because their brake lights come on randomly but they don't slow down.
