just been reading some posts had horrible images of people ragging their cars from cold.

i only take mine up to 3000rpm when its cold and only take it above once the needle is at 90`c.

i don't let it idle on start up though as this apparently is bad for the cat (not the one eyeing my car up from the neighbours... unfortunately [:D] ) and tend to pull away almost straight away, one my facia is clipped in etc.

i always laugh when the little boyracers at college get in their cold cars at lunch or in the evening and rant the balls off the engine to show off as they drive away.

does anyone on here wanto to admit to ranting the engine from cold? [:D]

I think that when you start your car you should drive off straight away, best way to get engine to correct temp.

On forced induction cars you should not drive hard till oil temp is up.

Mine comes out the garage in the morning and driven straight
away.Always wait for the water to be 90degrees and the oil to get to
normal temp before i drive hard.

Even with the water at 90 degrees the oil takes a while longer.

sometimes up to 30 mins to reach proper temp.

I'm totally anal about this.

I'll start up the car, and let it idle for about a minute. Then
I'll drive very gently for the first 10mins/5 miles before working the
engine fully.

Once everything is upto temperature, only the rev limiter stops me from going any further!

on any car the engine should be allowed to warm up before redlining it, or at least excessive revs.

think about it, cold engine, cold metal, so loose clearences as the metal is smaller, oil is cold so thick and not lubricating the bits like its should, plus all the oil that was on engine parts has drained off over night so some parts are only covered in a thin film.

yup, I let the car warm up while stationary for about 5-6 mins, then
drive it at around 10mph until the end of my road , sometimes until I
possibly can without someone jumping up my a$$ from behind ! My sister
always shouts at me for driving slow initially and thinks Im mad
warming the engine up ... I obviously tell her that her kind will NEVER
understand [:p]

I always drive off at a steady pace within a minute of cold starting.

I'll never rant it from cold.

I rarely rant it ever if i'm honest. Small matter of 13 points on the old licence, so got to be careful for another 19 months.

Another question worth asking would be:

How many turbo driver let their engine idle before switching off, and for how long??

Just get in and drive normally, but don't rag it until its hit 90 degress.
agreed[:D]
As said above, the 90 degrees is only the water temp and it does take the engine and oil another 10 mins or so to get up to temp.

Get in, turn on, drive normally then when the engine is up to temp.....I usually wait 15mins or so then give it some [:p]

I use the same warm up as most , just take it easy upto 2500ish. as for the turbo on switching it off i take it easy for the last mile or so and the let it idle for 30/60 sec while I get my self sorted out. Allways done this and never had a problem.

How important is it to let the car idle at the end of the
journey? Ive only had the car (gt tdi 115pd) a couple of weeks
and havent been doing this. Whats the reasoning behind it, how is
it different from just turning off the engine and letting it cool down?

Soz for the questions, but if you dont ask, you dont learn!

Yeah same 4 me. Let the ol girl warm up before bootin it. I always leave here to warm down for a couple of mins too.

Now put this question on a BMW forum & you'll get the complete opposite answer!! LOL I know so many of my mates that drive bimmers and rag them all the way up the gears from stone cold!

Those crazy kids!

On my PD130, if I've been driving hard, I'll drive at low revs (steady) as I am approaching my destination, usually 5 mins, then depending how hard I have driven it, may give it a few more minutes at the destination. If I have been driving normally, I'll just do the bit before I get to my destination, then no need to leave on when I arrive.

Traditionally, the problem with just switching off forced induction
cars after a good thrash was mineral based oils. Basically what would
happen was that as soon as the engine was turned off, obviously the oil
would stop being pumped round... The oil sat in the Turbo oil galleries
and feed pipes would basically cook from the heat of the turbo. This
causes the mineral structure to break down and form tiny crystals which
build up over time, in extreme cases leading to blockages and turbo
failure.......exactly like cholestrol in your arteries.......

With the wide spread use of synthetic oils (with higher working
temperatures) this is less common, but is still not advisable to switch
a hot engine off without letting the oil cool down....
