Picked up my new FX4 EcoBoost truck tonight. All I can say is Ford has come a long way since my 1976 Pinto. Very, very, very nice truck. Will be on a business trip tomorrow so will follow up with a mileage post sometime after work. First 20 miles home averaged 18.5 for what that's worth. As for the engine it's dead quiet and very strong for a little 6 banger! Let the mods begin.
