Settle an argument for me, please!
My buddy and I have been arguing over this for a few weeks and I keep telling him that he is wrong about this. He says that I should not drive with the tow-haul on all the time because it hurts my MPG...

I have 2 Fords and if in OD and hit the TH button going say 60mph it will shift out of over drive and the rpm will increase. I would assume that more RPM means less fuel mileage.....could be the reason it gets 17mpg without the TH engaged and 15mpg when it is.....Am I wrong or is there some other reason the mpg changed. This was on a 350 mile each way trip towing nothing.
