I stand corrected on downshifting causes an increase in fuel consumption. After an internet search it seems like it does not. I think this answer I found sums it up best. "It does not use more gas to downshift. It is the kinetic energy of the vehicle being turned into mechanical energy in the engine that makes it go faster. This can alternatively be turned into heat energy in the brakes, which makes the brakes wear out faster. If the throttle plate is closed (because your foot is off the gas) the engine cannot burn more fuel because it has no more air."
I am however still holding firm on no column shift. haha.
