Since I've had my 6 speed, I've probably used 5th a handful of times. Usually go straight from 4th to 6th and if I need to accelerate on the highway, no reason to shift into 5th, just go straight to 4th or even 3rd if speed. is low enough
And saves the clutch. No WOT below 3500 for me. My goal is 40,000 miles tuned. We'll see if I make it.
