leaving the car idling is a good way to encourange condensation in the engine and breather system.

ye, I posted at the same time lol
Same here. Thought they would be a waste, but they're awesome in this weather!

It does yes, the oil isnt flowing freely due to it idling cold! Best to get it moving soon as really.

I'd better get an ice scraper then. Usually let the heaters de-ice my screen lol.

I get moving as soon as I can see out the windows properly (in the work van)
Doesn't require any time wasting in the 200, apart from getting out to close the garage door.
Where I was working today though, I pulled on the drive to find an X5 sat there engine running, no one in sight... Not a problem though, the bloke came out the house 15 mins later to turn it off
If I ever have a need for an X5, I'll know where to find one.

Like your 200 ever ventures out if its cold, wet or dark

Could you show me where this is on google maps?

Its what I usually do
De-ice the windows first then get the engine running, you ideally want to bring the oil temp up quickly as possible, idling cold will take an age and do more damage to the engine. Not something I have really looked into regads to solid proof that it does indeed damage the enigine but its common practice really to get the oil moving round and to normal temp.

This time of year it runs while I scrape the ice off then I go. In warmer weather I just go.
It does run like crap for a minute or so though so I always take it easy.

Not sure how true/likely the cracking windscreen thing is but I've never done it just to be on the safe side. Plus scraping it doesn't take that long. A minute, if that?

I have heard for years that hot water will crack the windscreen so i try not to do it.
As for the car warming up i have always left the vectra for 3/4 mins till the secondary air pump switches off.
With the clio i guess it will be just aslong as it takes me to decide what CD to put in

It says in most manuals to drive off straight away, even old 80s BMW ones say drive straight away and never leave to idle.
Few issues(main first):
Oil pressure: This will be very low at idle when cold, especially when you haven't revved the car up at all. Oil creates a film on moving parts, the film varies in thickness depending on the temperature, also the mechanical parts vary in size with temperature, the gaps between parts(bearings are worst affected) are bigger when cold and hence need oil to fill the gap, when the engine is hot(oil and coolant) then the oil almost perfectly fills the gaps and lubricates the parts meaning that very little wear occurs within normal operating parameters. When the engine is cold the most wear occurs, especially under heavy loads and high revs. If you rev the car to 3-4k the oil pressure should be around it's maximum and hence will provide good lubrication. Also the engine will heat up faster. So drive off straight away, don't accelerate hard, do rev to 3.5k and don't rev low(sub 2k)
Bore glazing: When you leave a car to idle, the oil in the bores can glaze and cause premature wear on the liners. Oil can glaze on bearings too!!! Sitting at a constant speed cruising can also cause glazing if it's at light load.
Also someone could and would steal your car and you wouldn't be insured.

Quick scrape or warm water if bad and off I go. Used water for years without damage... Don't know how any can drive normally and stay below 3000rpm for 15-20 min unless they live in a very flat area.

lol keep it under 3k for awhile then when I get to the A22 give a few w*****s a run for their money

Relatively speaking, cars take an age to warm up if just left ticking over. All the while you've got nice cold oil sludging about. When an engine runs at its worst, you leave it like it :S
Much better to drive it, give it a few squirts, and generate some heat.
Leave your heater off for the first 5 minutes as well to help it along..
