2.08 gears + over Drive = 55 mpg +
Hot Rod magazine had article about a guy built an old milk truck with a 4 cylinder diesel and a turbo 350 GM transmission and took a trip with his son the truck didn’t come out of low gear until 60 MPH.

Moving in traffic behind a friend in his old diesel stickshift p/u, I wondered why he was rolling through all the stops?
Turns out, his ankle was bothering him and he did not want to use the clutch!
Just slow until it starts to bog and give it a bit of juice... No clutch action needed.
