I put my 2018 F-150 Powerstroke in Eco mode 99.9% of the time. The slower starts don't bother me, and I like to try to maximize my mileage. Tow mode seems to keep it in higher gears and downshift more. Rain/snow mode just seems to really reduce torque to the wheels at take off. I can feel the difference in sport mode, but again rarely use or need it. Anyone have any other patterns or reasons for selecting a different mode?
