i downshift regularly from 6th to 3rd, to pass cars on the freeway (the car feels slow otherwise) or to slow down on off ramps (sometimes i go into 4th and then 3rd). I revmatch perfectly. I used to downshift into 2nd, but it hit the rev limiter twice and now i go into 3rd and it never hits redline. Is that bad?

I've got an off-topic question.

To move the shifter from a gear to neutral, does it require stepping on the clutch pedal? Someone told me today that I can simply move it to neutral without touching the clutch pedal. Is that correct information?

If you use the brakes and the RPMs go down to about 1000, you can move the shifter into neutral without depressing the clutch.

The only way the engine would consume more gas, would be if you rev-match before downshifting. That would mean you blip the throttle for a second or so, and raise the gas levels in the cylinders. As soon you let off the gas and let the engine-braking do its job, there is no gas consumption whatsoever.
Easy there killer...I'm rev-matching
