I was jut thinking about that this morning.
It is 28 deg. right now.
I definitely see a difference in my 06 CTD.
I also don't drive very far day to day and i think that has as much to do with it as anything. My truck runs different and shifts different till it is warm, so that may be why my mileage is reduced.
i drop 1-2 mpg, but my chip helps a bit.
