# Ford C-Max Energi Part 4

On Monday January 7 of this last week, we put our first fill-up in the car. The odometer was reading 574 miles, subtract the 59 miles we started with (presumably on a full tank at the dealer) and that’s 515 miles on 12.45 gallons of fuel. We averaged 41.36mpg. Remember, Ford states not to judge mileage for at least the first 1000 miles.

A few thoughts come to mind:

1. The car says 230 miles have been driven on electricity, the balance of 344 miles driven on fuel. I’m a little confused here. Did we only go 344 miles on our 12.45 gallons of fuel. Yikes, that would be terrible mileage?? I need to dig in to the displays to see make sure the 574 is overall mileage as I am presuming and not just the fuel driven miles. Is my presumption wrong here?

2. Remember, midway through the tank, I changed the calculation from MPGe to MPG. It would be interesting to know if that effected anything or if there was a recalculation of the entire fuel/electric consumption so it reflected accurately at the time of the change.

3. I have not reset anything as of yet. I will perhaps do that when we get to 1, 2 or 3k so as not to have the break in miles figured into our average. Many cars don’t really give you a “since reset” average but rather a rolling average of only the last 300 miles or so. I’ll be interested to see how this car calculates that.

4. It’s notable the MPG calculator @ 40.7mpg is very close to my calculation of 41.36.

5. I hope I am not boring any readers. Writing along as I learn about the car. I’ll try to keep it down to 1 post a week on this subject. Expect them on Sunday’s. From here up was written on Jan 7th.
