I'm interested in researching this in my TDI a little more. The gearing in 6th is very high and I have experimenting with lugging in a high gear with as little throttle as possible to maintain speed and going into a lower gear and doing the same.
I haven't come up with a complete answer, sometimes the higher gear is better and sometimes the lower one is. I do the same route and try different things but its a toss up as to which one wins.
How does BSFC work for this ?
