- 2019 CX-5 Signature
16.8 seems abnormally low, even with a pretty heavy foot. If you're driving conservatively, you should easily be in the low 20's. I'm 80-90% highway with lots of traffic and run 28 - 28.5 on every single tankful.
If you're sitting at 5 lights for a minute each during your 2 mile commute, you will not come close to low 20's. I can understand how those that have 80-90% Hwy commutes can't comprehend this, though. In my Lexus, I went from a 25 mile commute, averaging ~26 mpg's, to about 14 when it became a 2 mile commute to the train station. This is just how it is. If it bothered me, I would get a hybrid, or full electric.
