i remember seeing a thread about this a while back, but i cant remember what it said...is it ok to warm up ur car or shuold i just start it and go?

 

People are really back and forth on this issue, with plenty of evidence to support both cases - I don't let mine warm up for any more than 30 seconds, it usually warms itself up pretty quick while driving - I do row the gears a few times through out of habit before I get moving but as for warmup, I like to get in the car and go, I just don't put it above 2500 rpms before it's warmed up fully.

 

Sit for 30 seconds to let oil circulate through the engine, but no more than that because it's supposedly bad for the catalytic converters, IIRC. Then drive very moderately until the car is warmed up.

 

1 minute warm up is enough IMO and i usually dont rev over 4000rpm until water temp is up to normal.

prolong warm up is not good for your engine because of low oil pressure at idle.

 

since ya get crappy mileage when its cold, i let it warm up a minute or maybe a couple mins depending if the gf thinks its too cold to go outside yet then drive conservatively for the first mile. by then the fluids are at least kinda warmed up

 

yea i usually never really let it sit for long and while im drive i make sure never to go above 3000rpms...but i was just reassuring myself...thanks

 

i used to warm up the car for 5 minutes, The only thing that warming up do for you is make you late for work.... sigh...

I just warm up the car for a minute, and just go. Again do go over 2500rpm until temp level is in the middle like it always should be.

 

first off the manual suggets 1 min warm-up. sec,,if your GF is fussing at you about warming up the car,,,tell her to put on some warm clothes...GAWD WOMEN!!!can't they understand our max baby is very imp to us????

 

Just have your girl turn on the heated seat....thats all I do when she complains...it heats up faster then the car does!!!

 

i let mine warm out for about 5-7 min

 

Pretty sure you meant do not go over 2500rpm.

Exactly! My girl always wears crazy short mini-skirts in the winter and always throws the heated seats on high - her butt is warm before the car is at warm operating temperature. Always surprised at how hot the seats get before the car does!

 

I wish my girl wore less clothing
Heh... heh.. heh....

 

about 30 sec with slow backup from garage and proceed with low rpm before heading out to the freeway

 

i let mine warm up until the temp gauge moves up above the first line or when the revs drop a bit

 

depends on where you live. if you have a long rural street and can tag along at 10mph you can just drive off, but if you are like me and need to merge into 60mph traffic right away, you better let that engine warm up.

 

I let my car warm up for at least few min before I start to drive. I'm used to driving my MR2 turbo.

 

I have a remote start (Viper 790XV) and I let it warm up for at least five min. I leave the heat set at 90 so that way i get into a nice warm car. Don't have heated seats..but I would rather get into a warm car, i guess ,than a cold one with heated seats.....Bring on the summer weather!!!!!

 

I'm pretty sure the manual says to let the car idle for 30 seconds before driving. It also says not to depress the gas pedal before starting. Oddly enough **I want to hear the discussion on this one** IIRC, the manual also says that if you shut off the engine and start it again before it's had a chance to cool, you're supposed to depress the gas pedal before starting the car. I have no idea why...?

Really...... you got me there

 

me too.

 

That doesn't make much sense, although one possible STRETCH of the imagination says, if the engine is still very warm when you start it up again, it may have trouble starting due to the air inside the intake plenum/manifold being very hot (heat-soaked), so maybe you need to give it some throttle to make it start faster. However, I never have a problem starting mine after it's warm, it DOES however start and idle at the normal low idle RPM (~600-700), and doesn't "rev up" like it does when it's cold (i.e. revving up to 2000 RPM immediately after catching ignition, dropping back to ~1100 in less than 1 second). Maybe that "revving up" immediately after starting is what they're after. Personally I'm fine starting my engine and having it rise no further than idle RPM. I don't like revving the engine up like that when the oil isn't fully flowing yet.

 

I just read the whole section on "starting and driving" your car and there was no mention of pressing the gas if you stop/restart while warm.

It does say if it doesn't start easily you should press the gas pedal... that's it.

 

Oh sh*t ... yeah dude, my bad

I wish I had heated seats... Hehehe

 

how can you guys stand shifting your car at that low rpm?

 

do you mean that you should warm up turbo'ed cars a bit longer than NA cars? why is that?

 

My turbo won't kick in as hard when car is cold.

 

did you see this on your boost gauge?

 

how long did u usually wait?..till the water temp was inchin up?

 

I wait about 2-3 min before I start driving

 

I dont need to see the gauge. I can feel my car and turbo does not want to spool up quickly. Everything is normal when I let my car warm up a bit and drive for few miles.

 

all i know is that i live in miami and let my car warm up for bout 5 min.

 

I let mine warm up for 30-60 seconds usually, take off, take it VERY easy for the first mile or so, then when I see the temp gauge start to rise above the C a little, I sometimes do some full-throttle runs up to 4K RPM or so
Gotta be hell on the catalytic converters, but it sure warms up quickly...

 

................30 seconds and I'm off. One of the many idling links I have bkmrkd:

Cold Starts (Idling)

 

normally about 2 to 3 minutes and i am off

 

When warming up, my thought has always been, why just the engine?!? That's why I let it idle no more them 30 seconds and then Im off.......That way the WHOLE car gets warmed up; trans...etc....Peace_

 

me too..

 

30 seconds to 1 minute and I'm off, but don't run the engine at heavy loads, plus the notchy tranny doesn't help either. The first 5-10 miles (depending on the temperature) I avoid WOT runs or rev it past 2500 rpms. (about two weeks ago after leaving my office in near zero temps, a 2k2-3 with clear corners was up my tailpipe, but I refused to push it just because a fellow max owner wanted faster starts off the line. I figure he'd understand and if not, the left lane opened up shorlty after).

 

I recall a GM site from Canada saying that the idle consumption is roughly 30 seconds vs. startup, not 10 seconds like that site mentions.

But yeah, the engine definitely isn't the only thing requiring warmup. Strut oil, wheel bearing grease, transaxle oil/parts... it's all important.

 

if you cant confirm it on a boost gauge.....
It can be that your car is in open loop operation when cold. You are running rich during open loop and that's why you feel a bit power loss when excessive amount of fuel is delivered to the engine. It is not going to affect your WOT performace, but you might notice some low - mid range power loss.
