Bought my C Max in August 2015.  Had 24 mpg on car at that time.  I did not not do a reset and now I it reads 44.0 mpg for over a total of 92703 miles.  This is combined city ( local courier ) and highway ( longest one way trip of 724 miles ) at speeds mostly 65 to 75 mph.  Even with towing my boat for 150 miles on highway...

I have used AMSOIL in many vehicles with great results.  I used the Signature series oil with their oil filter and observe the 25,000 mile/ 1 year change interval.  I have found that my mileage actually increased by using this.  My 37 foot motorhome with chevy 454 went from 6 1/2 to 7+ with nothing more than changing the oil.  If I change the transmission fluid should increase even a little more.  My Kia Sedona gained about 1+ mpg when I changed and it was a high mileage vehicle when I got it.

I drive lots of miles ( average 3000/ month ) as a courier, about 30% interstate 70% city.  So far on my 2015 has an average of 44.3 mpg with normal driving.
