I have a 2006 F150 Supercrew truck I primarily use for the farm. We also take it on family trips since it is very comfortable. I put very few miles on it because the MPG is, at best 17.
I commute in my old Tacoma.
Yesterday I had to make a run to pick up a load of horse feed. Driving home (about a 20 mile run) I started to put the truck in neutral going down hills to take advantage of the enertia.
Using this technique, the difference was at least two MPG has registered on the trucks dash display. Wow.
My question is: Am I doing any damage to the trucks transmission moving in and out of drive? I can find nothing in the owners manual that addresses this issue.
Any advice is appreciated.
