Here's the most recent re-fill, lots of highway driving on this one.
7/6: 234 Miles / 7.671 gallons = 30.5MPG—Solid; most driving was on STL area highways during the July 4th holiday week at 70-80mph with the AC on and at least one passenger.
Prior full fill on 7/4: 271 miles / 10.839 gallons = 25.0 MPG
Fuelly reports my current running average is 24.2MPG. City miles drag down that average; recently, I've been doing a lot more highway, the CX5 loves to run.
