Not bad. Keep an eye on the tire pressure and rate of acceleration and that can help.So I just bought a '22 Sport. This was my first week commuting to work with it. I drive about 90% freeway and average around 75mph. Had to refill my tank last night and thought I would share my numbers.
2022 Crosstrek Sport with 1,200 miles on it.
395.2 miles driven
13.342 gallons to fill up
30.9 MPG per the dash display
29.62 MPG hand calculated
Hope it improves as I get a few more miles on it but this is still a huge improvement from the car its replaced!
