Took a little drive this morning to get some E0 gas. 45.5 MPG in the Fiesta for 180 miles on just under 4 gallons. Saw a peak of 53 MPG coming home on Route 17 through Gloucester. This is the 6 speed automated manual. It seems that the car likes to shift about 3k RPM for decent acceleration, lower in the higher gears 4-5-6. The mileage actually is better at 65-70 than it is below 40 at steady speeds.

I did try some stealth P&G. This is where I accelerate very gradually to about 5 above my average, then very gradually decelerate to about 2 below. The cycle takes about 35-45 seconds and it seems to be working with the FE pushing 50 MPG at 55 MPH.

On the Interstate at 65-70 (PSL 70) it looks like about 43-44 MPG average. The factory FE gauge seems to be very close based on a single fill, will see how that averages out.
