Hi, we purchased a used C-max 2013 SEL manufacture date 10/12, two weeks ago. The MPG is so erratic, varying from 47 for my 100 mile down hill commute, to barely 22 city driving. Average temps here in the WA state Tricities area have been over 100 degrees, have been trying to spare the A.C. Have also been trying the pulse and glide but obviously haven't figured it out. What's ICE? Also, never had a car so attractive to bugs on the grill. Love the spacious interior but too stressed out about Mpg. Any hand holding available?
