Warming up of Cars

Do u guys warm up ur cars before driving off? If so, how long do you warm up for?
What is the main rationale behind warming up of cars?

I think it is...like it says to warm the engine....applicable to cold countries.Originally posted by speedygonzales:Do u guys warm up ur cars before driving off? If so, how long do you warm up for?

I once read somethere that says warming up of cars are actually not necessary for modern cars...you can jolly well start your engine and engage that gears immediately. Do need confirmation on this though...but I don't warm up now a days. -
I practised it especially after a long stop... example overnight. The RPM is normally quite high after the starts (1.5-1.6k) and i let it idle to 1k or below before driving off unless i am in rush of time.Originally posted by speedygonzales:Do u guys warm up ur cars before driving off?

rationale... let the engine mechanical parts and oil warm up first before putting pressuring it when moving off. Some people told me for petrol engine is not needed and only applicable for diesel engine but i have been doing it for so many years now and i guessed i am used to it now... -
car that runs on petrol need not wrm up nowaday, turn key and go

AFAIK, the engine oil stops circulating once you stop running the engine, and it will slowly collect in the pan.
When you first start yr car, it takes a while for the engine oil to recirculate throughout the engine to provide the lubrication. Getting the engine to warm up a little bit is good practice. It ensures that the engine parts are sufficiently lubricated before you start engaging it hard, and ensures you won't suffer premature wear and tear.
Idling too long is also not a good idea. It is something to do with your spark plugs.
A good guide is to wait for the engine rpms to drop to abt 1000rpm then just drive slowly and gently first thing. -
There is not a need to warm up car.From what i read from somewhere (i think its from highway mag) warming up car is actually wasting petrol.just drive off and keep your RPM low.wait till your oil TEM become ok then continue the way you used to drive. this is refering to local cars due to the weather.

Hi speedy,
Warming up of the engine would mean warming up of the engine oil. I agree with dh on that point.
There is an optimum working temperature for the oil and this would definitely be part of the engine warming factor.
With the optimum working temperature, the engine oil will serve to lubricate your engine parts more efficiently rather than from the cold start stage.
There may be other areas that need to be warm up. But with technology nowadays, engine are built with very good tolerances, perhaps the wearable parts , like seals and bearings, would not be damaged, if the tolerances are within controlled, when running the engine without proper warming up.
You may not notice the effects immediately, but the stresses built over prolong exertion of poor lubricated engine parts can lead to premature failure of the wearable parts and even to the engine itself.
Warming up may not be limited to the engine exclusively, but being just a car enthusiast, my knowledge is not quite as far reach as an automotive builder.
To sidetrack from the topic,
You may wish to read on this useful link.

Have a good day.

But Audi/VW cars dun need to idle warm up rite? start,drive off gently,till temp builds up 90DegC..correct me if im wrong..Originally posted by DoggieHowser:AFAIK, the engine oil stops circulating once you stop running the engine, and it will slowly collect in the pan.

Normally car at idling waste more fuel...Juz drive slowly to warm up instead of letting it idle

i learn from a car expert that modern cars nowadays need not warm up b4 drive off.
In the past where technology is not as advanced, u need to step on the accelerator when u start and warm up the engine...but now so need.
just start, drive off slowly will do. -
If u long time nv use ur car, its beta to warm up a bit first... maybe for 5 - 10 mins.... as mentioned by the bros here, its for the engine oil to flow...
It will be a good practice.. rather than juz start ur car and drive off after a long sleep...... -
errr....try warming up your car engine under hot sun. maybe warming up youself in the same time
