If it is flat and, say 2 people, how much do you rev to when moving a car from stnadstill? what's the minimum amount of revs so you don't labour the engine but also notto rev the nuts to minimize damage from a cold start

car in question is the 1.2 12v htp

your driving instructor should help you with your question.

I'm totally confused. :S

You want to be at the lowest revs that produce maximum torque, usualy around 2k rpm for most engines.

80,000rpm. should do.

Alternatively, when the car starts moving it's enough.

What?.

This is almost like 'how long is a piece of string'? But I understand where you are coming from. The 3 cylinder engine can require a few more revs when moving off, than a 4 cylinder engine especially when loaded or moving off on a hill. But the revs themselves are not really the most important factor. If you use the clutch gently, holding it at the biting point as the car begins to move and letting it up fully once fast walking pace has been achieved, it's possible to move off with almost tickover revs on flat ground. But in reality you want a few more revs than that to make good progress. On the other hand if you rev it hard and drop (lift) the clutch more quickly, you can take off really fast. But that's not good for fuel consumption or clutch wear longer term. So you need to practice and find a happy medium. The technique will differ too in different conditions, up or down hill, loaded unloaded etc. But don't over think it. Listen to the engine and learn from you own experience. We can all be a bit different in our technique for moving off. Don't worry about the engine, a few too many revs when moving off even when cold won't hurt a thing. It'll look after itself. Enjoy your car and practice, practice. :yes:

My wife swapped her 1.9Tdi Fabia for a 1.2 12V. The 1.9TDi would pull off on tickover if you had 20 people in the car and a caravan on the back on a 1 in 1 incline. The 3 pot does require more throttle and clutch balance especially when loaded or on an inline.

Saying that whithin a week she'd got it sussed and now loves the peppy little 3 pot unit. I quite like taking it out around town as it loves to rev with that 3 pot burble, sounds like a little scooby and you can flick through the gears and still be whithin the speed limit.

My Passat would leave it for dead and at non motorway legal speeds keeping up with traffic you never exceep 2k rpm and the engine is virtually silent, but for the same sort of roads the 3 pot is a ball of fun.

It is an engine you need to get used to though as it does need a bit more throttle off the line than bigger units and the gearing is fairly short.

i'm not asking about technique (i've been driving for nearly 9 years now)

what i'm tryng to ask is, because of the cold weather you don't want to rev too high from a cold start but at the same time you don't want to rev too little to labour the engine.

obviously if the engine is already hot, it's ok to rev higher. perhaps I should have asked: what is the maximum you should rev to when the engine is cold to minimize damage?

i would avoid going over 3000revs before the oil warms up

how long would it take?

typicaly 6-10km of driving. Idling on the spot is the worst way for an engine to warm up as hardly any fuel (hence generated heat) is being used so the engine takes Forever to warm up.

how many minutes or hours? i better drive under 3000 revs for the whole of the journey then

my morning commute can take up to an hour, some times up to 20-30 mins to move like 2 miles due to rush hour

seriously?

around 10 mins of driving give or take - depending on ambient conditions to reach +70c oil temps. if you have the maxidot you can switch to oil temp sensor and see it during the warm up.

You're over-analysing. Just don't rev the balls off it or slip the clutch for ages.
