I have had this truck for about a month now. I am getting a very disappointing [I will round it up] 13 MPG. It has a 4.0 V6 and auto trans, 4x4 extended cab. The year is a 2006. I have had a full size 93 Dodge 3/4 ton 4x4 Cummins Diesel for the last 13 years. Thought I would avoid the high price of Diesel Fuel. BUT, I was getting an honest 21 MPG with the Dodge when I pulled the plate. If I could get 17 or 18 MPG with the Ranger, I would be happy. I am NOT happy. Is this a normal MPG for this truck??? Maybe someone on this forum could advise me what to do if this is not normal. I will be all ears.
