After parking one day I noticed that some update was taking place on my screen.  But I was in too much of a hurry to notice just what it was.

On the center MFT screen? That means MFT crashed & is rebooting. The car says "scheduled maintenance" when this happens. This is an APIM issue & has nothing to do with how the car drives.

I have to laugh reading this post.  I used to have a 2010 FFH, and now I have a 2013 FFE.  I would always lament the onset of winter and the impending decrease in MPG.  So a trip that used to be 41 or 42 MPG was now 34 or 35.  And I'd get upset.  Until I realized that DUH! I'm getting 34 to 35 MPG!

 

I understand, we all want to max out our MPG.  But at the end of the day, we are getting better MPG than 80% of the vehicles we share the road with.

THIS!  

 

I was complaining the other day at work at how low my mpg had dropped in the last few weeks.  Everyone agreed with me until I told them it was all the way down to 33 mpg.  They angrily muttered under their breath that they were in the low 20s.  So now instead of crying about it I brag that I'm getting 33 mpg!

Yeah...my old Ford Fusion V6 would skyrocket in the winter too...like up to 12.8 liters per 100 km (US 19mpg) given shorter trips and the cold. In my new 2015 FFH. I'm still getting 7 liters/100 km ( US 34mpg) even though a lot of my trips this time of year are, as I said earlier, short and the engine barely has time to get efficient. Went out to the shooting range 55km out of town yesterday in the lo 20sF and got 6.3 l/100km (US 37mpg) going out and 5.1 l/100km coming back (US 46mpg).

 

The range is up on the plateau about 300 meters up in altitude from my house and the long, slow climbout/descent really does make a difference.

I swear depending on what gas station I fuel up at really changes my gas mileage and it is very noticeable.

Could it be different mixes of ethanol between 0% and 10% (or whatever the allowed range is?)???

Have you try blocking the front grill?

I've used water pipe insulator foam to block my grill. The engine stays hotter longer, therefore mor EV km. It was -20 the past two weeks, and i'm still averaging 5.7L. (40 MPG+)
