Merry christmas everyone. With this 7.3 I just like the tow haul around town as I love putting my foot into it. On the hiway normal, never tried eco. Something strange happened tis past summer. Prior to I was always aound 20-22 litres per 100 km or 12 miles per US gal. This summer Idrove a thousand mile trip at 50-60 mph as we dont have freeways up here in northern Canada like you do down there. I now do avg 16 mpg US. In town driving like I do hasnt changed.
