Take a hard look at temperature and wind direction. I get anywhere from 30 to 42 MPG on a particular 60 mile highway route depending only on temperature and wind. That's with identical speeds and driving style.

The 42 MPG was on a 75 degree day (no AC) and a direct tailwind about 15 MPH.
The vacuum gauge plus wheel covers helped increase summer 2015 mileage to 38.5 MPG, while summer 2016 mileage was 38.6 MPG without the wheel covers. Drove 33,021 miles 2016-2018 at 35.00 MPG.
