I had actually had a question about this and was glad to see the topic brought up. This is slightly off topic but, engine breaking, what are the advantages and disadvantages? My dad taught me to do it when I was re-learning to drive standard a couple years ago (I'm only 22) and I have been doing it ever since assuming it was good for something but it seems revving the engine as you slow down would use more fuel even if you're not on the throttle. Does this method only save the breaks? If so I think I'd rather save the gas and replace the breaks earlier.

On another note, if I'm doing P&G without shutting off the car just pulsing then holding the clutch in until it slows down, then speed matching, would I be better off to pop the car out of gear then just a quick clutch to put it back in or will holding the clutch in for the period of the glide be safe on the clutch/tranny?

Also, I'm an Engineer and have learned more in a few days on here then 50% of my classes in college.
