I have a new 06 f-350 6.0. I just got back from florida towing motorcycles my mileage was around 18 when I left now that I've been home a few days mileage still down around 11. Anyone ever have this problem truck has about 6300 miles on it.

That's really odd. I can't remember if I have read anything like that or not.

I own a 2005 F-350 dulley 4x4 crew cab with 25K miles. I pull a 35ft 13,000lb 5th wheel RV, after returning from our last vacation in Aug. I noticed my mileage has dropped from 17.6 to 14.2 mpg. I hope you get an answer to you post I will be following it, I am curious to see what may have caused this.

Well I Have A 04 Dually With 48000 On The Clock And I Am Experiencing The Same Thing. It May Be Because Of The New Usld Diesel Fuel Or Maybe The Winter Grade Fuel. Not Sure What Is Happening But Everything On My Truck Checks Out And No Problems. I Buy My Fuel At The Same Place Every Time So I Know It Is Not A Change In Fuel. Hhhmmmmmmmmmmmmmmmm....................?

I had that happen, and took it in, and it was Bank one injector dropping about 20%, they changed it, and its all good now.
