I bought a 2004 Dodge Ram with 4WD and the hemi V8 this year, the MPG has been terrible, average about 7-8 all the time!! no change in towing or when empty?I figure it should be getting about 15 empty. It does have one bad oxy sensor but was told that only accounts for about 1 MPG. Anyone else having problems with their dodge MPG? or know what could be the problem? I always watch my tire pressure and it has a K@N intake and filter which I clean about once a week! i cannot figure what the problem is, but I really regret not getting an Isuzu like I wanted to originally!Thanks guys.
