First Tank completed

[lewisb01]

So I finished my first tank of gas and the first half of it I didn't know how to drive the car and I was avg. 37 mpg. When it was all said and done I managed to get the car up to 41 mpg with 498 miles. It said I had 25 miles left in the tank so I probably could've gotten another 40 miles between gas and ev miles.

 

Second tank is halfway done and I'm getting 45.7 mpg so far.

I think I might be able to hit the magic 600 miles mark with this tank.

You'll be pushing it at "only" 45.7. No need to try to hit that goal on your second tank! Let spring arrive and enjoy your new ride. You'll be getting loftier MPGs soon enough.

I'm not sure how much of this is myth vs reality, but many people report that their mpg numbers creep up gradually for several thousand miles as a result of the break in. It's not just the hybrids either. EcoBoost owners say the same thing. I haven't noticed much of a difference myself, but I'm not really paying attention to it at that level of detail.

I didn't notice any difference at all. And I paid close attention to fuel usage and mileage for the first few months.

I think its more that you learn how to drive the vehicle in the first couple of weeks/months.

Same for me. Any MPG improvements resulting from "break in" are dwarfed by temperature and driving technique.

Ford puts 4000 miles on every hybrid and Ecoboost before they will ever run it on an EPA fuel test or give it out to any media for evaluation. They wouldn't go to that expense if it was just a myth, they obviously have some data behind it.
