I finally went on a long trip. 389 miles worth. Her is a screen shot from Acar app. I use it to keep track of my car expenses and maintenance. It shows 376 miles driven and I had 10 miles left according to the cars computer.
I drove the whole trip in eco pro mode.
It was 90% highway
mileage calculation 376 miles / 12.678 gallons = 29.65 mpg
manual transmission
ignore the "Fuel Efficiency" as that is what I am getting as a whole of driving, now at 2400 miles 80% rural and 20% highway.
I found out a few things on this drive. If I needed to pass someone not getting out of the left lane, all I had to do was floor the gas and it was like I was in sport mode. Car jumped into action and took off. this was a nice surprise as I was worried I would have needed to switch to sport mode to make evasive maneuvers if needed.
I also noticed doing 75 or less eco pro seemed to gain extra mileage and showed blue. Over 75 it showed mostly gray and wouldn't gain extra mileage.
This is about as good as my old 135i. 25 more horse power and I still get the same mpg. Not bad.
