Wife redlined the car in second gear....yikes

Most the cars I drove for the first few years of Driving didn't have Syncromesh on first either, so for me it's just a given that you don't go into first until you're at a complete standstill...

And coasting is just a big no no... For both the above reason, and the previously discussed fuel usage (coasting engine uses fuel, slowing in gear doesn't).

If the engine is running, it's using fuel whether coasting or in gear!

It's not like you coast for a great distance. Slow down then disengage when the revs are down. You're already on the brake.

I guess all these answers show that "modern" engines and gear boxes can handle a lot.

Been driving manuals for 36 years, the last 17 almost exclusively manuals. Never had a transmission or clutch failure-had 160K miles on the Probe GT on the original clutch when she was totaled.

Nosa, you'll love the Dragon. It's fabulous in the Z, but if you have anything small and sporty it will be a blast. I've seen all kinds of cars on it, and the vans driving it will frustrate you.

I thought modern fuel injection engines shut off fuel when on overrun and the wheels turn the engine over. Old cars without direct fuel injection this was not the case and fuel was still sucked in.

At least that's what my Dad taught me.

I don't think that's correct. If you are on overun then the fuel is totally shut off . If you are coasting then fuel is used to keep the engine turning, just the same as if it were static. so in effect if you coasted down a long hill or to a stop you'll be using fule all the time. Granted not much but still using it.

Coasting is a bin 'no-no and ther are no circumstnces where I can think of it being acceptabe.

Na, if it's on the over-run, ie: the cars speed is greater than the engine speed, then it should shut off the fuel and just let the engine turn-over on the kinetic energy of the car. You can see it doing that if you watch the OBD readings whilst doing it.

If the ECU continued to feed fuel into the engine on the over-run then you'd have no (or very little) engine-braking effect.

I managed to blow the engine on my PGT, but I was on a track-day, so, well, all bets are off on a track-day really
