Default How long do you let your car idle before taking off?

Im mainly talking about in the morning. I park in the garage so I always go start my car a little before
Im ready to leave. But later in the day I dont wait as long...like when I leave work...I might wait 30 seconds and
then I take off. I tell my mom to do the same thing with her Legend...and sometimes she does, but usually I
see her crank it and out the driveway she goes!

Just wondering if anyones lets their car sit and idle before rolling out?

I usually let it sit for a min or so...but I don't take it over 3-3500K RPMS until its fully warmed up...

Ditto...until her idle is between 800-850rpm.

I personally think that is a little excessive, although I have been guilty of doing that during cold chicago winters so I get heat immediately.

Reason being is that oil pressure is at its worst at idle. I have read several places that the longest you need to "warm up" a modern fuel injected car is no more than 30 seconds to a minute, if at all!

ditto. this is usually 10-15 min. I treat her like a turbo... Same goes for cooling her off after driving...

I take off almost immediately (summer), but keep the car below 4500 or so until the gauge is all the way to standard operating temp.

In the winter, I'll let it sit for a short while (maybe 45 seconds or so) but then will go ahead and move, once again keeping it below 4500 until the temp is up to sot.

you guys shouldnt let the car idle till the temp is normal, it's suppose to be bad for your engine. Wear usually occurs at start up due to lack of engine oil and idling your car prolongs it. I usually warm it up for 45 to 60 secs and drive under 3k rpm until temp is at normal.

I start the car, fasten seat belt, find radio station then take off. I'm guessing it idles a minute or less.

In the winter I'll start car, scrape ice from windshield if necessay, fasten seat belt, find radio station then take off.

i let my car idle for like 10 seconds. Our oil jets dump oil all over the engine imediately when we start up. I don't see any harm in driving off. I just let it enough for the car to settle into its rythm.

From my discussions here and on Audiworld (I have an A4 too), idling for too long can be bad because you do not get sufficient oil pressure. Also, you are more likely to get carbon build-up and whatnot at idle. On the flip side, you don't want to leave before all the parts are lubricated or if they're cold and whatnot...

I try to let the car idle for 20-30 seconds, then just drive slowley and gently until everything is upto temp. In my A4, I let the turbo cool off, esp if I've been boosting a lot. For my GSR, I don't let it idle very long before shutting off...

Thoughts?

i start and drive. I try not to run high revs until it gets warmed up though. Ocationally i get a little to jumpy and I dont hear the VTEC engage, so i know ive been bad. But ive never red-lined from a dead start and cold. That is bad. Just normal driving till it warms up.

I think the Helms manual and/or the owners' manual has some words on this... To the extent that the car warms up better when driving at low speed.

Taking this to heart, I let my R sit at "high idle" (about 900~950 on the voodoo tach) for about a minute or two as I buckle my seat belt, select a CD or tune an FM station... and then I putt around at 4k rpm or below (I try to keep from lugging the engine - that's worse) until the water temperature needle is at its normal point (again, remember the temp guage is rather inaccurate, too...)

After that... it's war.

It depends on how late to work I am that morning...usually between 2-5 minutes, anything less in the morning and the car doesn't like me.

Yeah, you all need to start moving after 30 seconds at most. Sitting there in idle is just wasting time, gas, and maybe wearing down your engine. It's not hard on your engine at all to pootle around under 4k.

I turn on my car & immediately take off hitting REDLINE. That will surely warm up the car faster.

The best is to start the car normaly, then after a few seconds take off and drive slowly under 3500 and 4000rpm it won´t hurt your motor at all. Ideally you should get a oil tempreture gauge so when the oil temperature hits 70 to 75 degrees you can drive hard, cause when the water temperature gauge on your oem display reads normal tempreture doesen´t mean that the oil is. Oil takes longer to hit normal running temperature than water.
So don´t worry too much about heating up your car at idle, not good, just drive slowly until at least the water temperature is up at normal

Hmm. I didn't expect so much digression on this. I usually let mine warm up for 4-5 minutes in the morning, at least until the temp gauge has moved a few notches up.

Here's my reasoning -- After seeing the difference in wear on my stock, 20k mile ITR cams and Jack's 25k mile ITR cams, I'll warm the car up for a while. There was a noticeable difference in wear on the journals of the two sets of cams -- mine being worse for wear, so to speak. Nothing bad, just more scored than Jack's, which looked brand new.

Let the idle get down to around 1100 rpm before moving...

Under 3500 till up to temp (normal guage position) then drive for at least 10 min. after that

Shut down... Let fan cycle at least 2 times before shutting down. Got that fron my 3.5 years of TURBO driving (oil cooled turbo).

I am not in that big of a rush to warrant starting right up and heading out.
