Just curious if anyone else notices the same problem. I have a 2012 F-250, everytime the light comes on "Cleaning Exhaust Filter" for the next 8-10 minutes my MPG goes down to about 12 instead of 18-20+ I noticed this when I had the cruise on about 60 mph and on a flat stretch of road for about 35 miles, so it was consistent in way driven. Is this common or just my truck? Curious what is going on:dunno:

That is the best first post I have ever seen. 100% correct.
