There are times it would be advisable to manually shift or lock out gears I’m not arguing that. I am saying that revving an engine higher under light loads with the idea of increasing fuel economy is foolish. No one in their right mind is going to make it a habit of locking out overdrive gears to increase their fuel economy,
I never said to revving to 1,800 rpm is a good idea under light load. In fact I said the opposite that under light loads it is best to be at the lowest rpm and higher gear possible. The 1,800 sweet spot only comes into play when you are moderately to heavily loaded, towing something with high wind resistance(like an RV), and/or going up grades.
Also, 5th gear is still overdrive on both my Ram and your Ford so you are not taking out all of your overdrive gears, just one of them. I also have 3.42 gears which puts me exactly at 1,800 in 5th at 65 mph while 6th puts me below 1,400 at the same speed.
