Speaking of changing my commute, I stayed at my house in Aurora last night. This commute include about 23 miles of Interstate and 12 miles suburban roads. 35.1 miles , 66.4 MPG ( ouch). Tank also dropped to 524.7 miles , 75.7 MPG. Back to Lombard and the "efficient" 15.4 mile commute today at 3:30. I'm planning to keep this tank above 75.0 until time to fill up again (Thanksgiving?).
