Welcome back to the grind Filled up yesterday with 87 E10 at Amoco for $1.999. 578.0 miles , fcd = 66.3 x .956 = 63.3 MPG. 578.0 / 9.316 gal = 62.0 MPG. Maybe I will use a multiplier of .935 and see how close that is. I want to assume that the pump clicks off the same way every time. Yesterday's trip home was good. 31.3 miles ( including stop for fuel ) , fcd = 75.2 x .935 = 70.3 MPG. This morning , 37 deg F in Naperville and Elk Grove. Wind N 6. 35.1 miles fcd = 61.1 x .935 = 57.1 MPG. Ouch. Oh well , April is the month that comes in like a lion and goes out like a lamb.
