I have only driven the truck about 20mi from the time I put the airdam on, on my first drive with it the radiator temps stayed down
and the truck was less affected by crosswinds
I suspect I am running right around 19-20 mpg right now but won't know untill I fill up on thursday(payday) I have driven 245 mi (gps)on a tiny bit more than a half tank 20g tank.
The wife thought the airdam was factory
