Skip shifts?

Usually now I've gotten into the habbit of skipping gears whenever I shift (i.e 1-3-5). I usually try and rev match it to the next gear the best I can as to not put too much wear on the clutch. I've gotten lazy to the point where I don't want to go thru every gear here in the city and my thinking is I save a bit of gas too.
Am I doing any damge to synchro's or accelerating wear to any other parts?

Skip shifts?

Only damage you could cause is if you Lug the engine.

Skipping shifts are fine. I skip from 1st to 4th in the corvette when I'm feeling lazy.

Rev match up or down. You can rev match either direction.

i.e. Got the car going up to 40mph in first, at say 4000 rpm, release, drop down to say 3500 rpm and drop into second. Seamless, smooth shift.

Yes, I've seen some corvette's that will lock the gates so you have to go from 1-4 as a gas saving feature.
Also you can rev match your upshifts for smooth shifting, if you get it spot on you don't even need to clutch, although I have heard that, that will wear your synchros.

I don't skip on the upshift, but I do on the downshift. 5-3, 5-2, 4-2. On a 4-2 I actually put it through third, then into second without releasing the clutch, not for any reason, just something I've always done.

I grew up in England, pretty sure if you skipped an upshift you'd fail. Block downshifting was allowed though.

As long as there is no lugging, you will be fine. Matching revs helps quite a bit. May not actually save gas. In the city, though, I'd be more concerned about not being in the "right" gear (torque band) in an emergency situation.

I often skip shift, but it is generally on lightly-travelled roads rather than in traffic.

I have a really interesting way of driving my stick because I am trying to promote longevity for it and it dosnt help that I have straight cut gears.

I shift 1st gear at 20 mph, 2nd at 30, 3rd at 40, and if I am cruising under 55 MPH i always keep it in 4th gear. Any speeds above 55 to about 80 its in 5th gear and I only go into 6th whenever I go above 100

Sometimes I skip 1st and start in 2nd and go straight to 4th. Just depends on driving style at the time

I know that at 40 mph in 2nd gear I am at 4500 RPMs with an 8k redline so when I shift to 4th from 2nd it falls to about 2100 rpms so I just put in the clutch and just as its about to hit 2100 rpms I let it out and it catches perfectly. Sometimes I will miss it and revmatch up again. Like I said, just depends on style

+1. I am sure the ratios are different, and obviously vastly different mechanics, But in the same idea, that is what the automatics do as well depending on driving style. (Start in 1st or second)

Skip shifts?

I usually redline second and then go into fifth gear and start cruising.

3->5 isnt too bad. 2nd gear start is too bogged for my taste.

I came from a mustang.
