Sorry to blab on, ill stop after this. I agree with all of you guys to a certain extent. Much of what im trying to say is i think if you find yourself in a situation for example where you want to save gas, and you rev up high let's say merging onto a highway to keep
up with traffic, I agree it's probably best to just go ahead and skip a gear or two to save gas since your already at higher revs, no need to go through the other lower gears. But If you had the opportunity to merge onto that same highway without being forced to accelerate hard to keep up with traffic and then skip to the final gear, i think slowly and steadily shifting each gear to its manufactured recommend range would suffice the best fuel economy.
