Looking at buying a 64k mile 250 crew cab with 6.2L. While test driving went thru computer and saw the mpg is showing 4.3. Mentioned to salesman, he stated its because its only been driven around the yard. They have had for 1 month. No soot in tailpipe as though its running rich. Should I be worried?

Have 2011 Escape with trip computer it mpg has always been consistent over several fill-ups.

looking forward to using this truck to pull our RV thru retirement. Thanks!

 

reset then take for a test drive of about 10 miles. You will probably get about 12 mpg.
