I read in another post that sometimes your truck can have a clogg either in the intake(CAI) or muffler(cat coverter) does anyone know anything about this or the signs that i should be looking for .Sometimes i wonder if my truck has anything colgged im getting 10mpg city and 17-21Higway.

 

Nope, not clogged. You do a lot of stop and go traffic in the city or you make frequent stops. 17 - 21 is good mileage, bordering on great.

 

Yea, I wish I had your mileage!!!

 

I am enviousof your mileage.

 

(snicker, snicker, giggle) He has mileage envy.
