How long to idle after coldstart ?

[TermiziYeoh]

Guys, how long usually u guys leave your car to idle after coldstart before u start to drive it ? As u know immediate run after coldstart will harm the engine and shorten engine life. Read in the book before,let the car idle for a minute or two, then drive it slowly after few km then only can drive it to desire speed. Any comment ?

How long ahh... Mine never do any warm up, but drive around 20-30km/h for few minutes and till the radiator temp go to normal condition ~45-50% then only go fast at 120km/h.

my engine warm up time = time for auto gate to slide open

Forgot to add another point, if warm inside the house, all the unburnt petro will go to our house and is very smelly. And the unburnt petrol will cause cancer because of its Benzene content.

aiyo, i usually just drive away without letting it to warm up.....sei lo sei lo.....:shocked:


Cheers!!!!!

5 mins...

don really know how long but i let it idle from 1500 rpm till it drop to 700-800 rpm.
then watch temp till it goes around 80-90 C.
after that, tekaanlahh..

I think this topic has been discussed b4 tat day i stumble on some old threads dunno where is it ... some say that idle first better, some say best is driver straight away... dunno la.

i normally drive away once i start, don't on aircond until the auto-choke is back to normal RPM then if i wanna on aircond only i'll on ...

damn i need a water temp gauge.. like that best lar..

dont need to warm up cuz when u crank the engine upon ignition,oils are circulating edi...OR you can just leave it idling for 1-2mins...sakit hati enuf to leave it idle n waste petrol ler...

I normally leave my car to idle for 5 mins!
However, I've read from the book that we can drive our car straight away after starting the engine with the speed of 20-30 km/h till the tempt reach 80-90C.

dunno whther true or not, heard from someone before....but come to think logically it sounds okie:

when u left the engine long, the engine oil and water would subside. So after u crank your engine, all the parts would go into motion. You got to let it for a few minutes to get the engine oils to relubricate the parts and also the water to flow smoothly.

That is why my timing rely on my tappet sound. When the tappet sound goes smoother and close to no sound, that's when I go (meaning enough lubrication). Also depends on whether or not rushing, if rushing for time; than f*ck the idling.
Problem now is after I used Q8, there's no more tappet sound.............but I still wait, usually finish 1 ciggie.

hmmm..wat i will do is to let it idle until the temperature goes back to normal level..then only speed off

 

[AccordRacing]

some car might auto warm up engine such like rev around rpm1300 then when reach the working temp will drop to normal idling 800rpm,its take about 2 minute,i always do this,becoz the engine oil viscosity will change due to temperature change,tats why if didnt warm up n go,its will cause more engine wear off

 

[PocketRocket]

then its dependant on what oils ur using edi....then very subjective and goes according to car makes n models edi...you think Q8 oils no mo tappet sound..? try 'endless'...much much much smoother than Q8...

 

[RPM_freak]

i read in an msn article that instead of letting your car sit the in ideal, you can drive it very slowly at first and as the temperature increase you can drive like normal .. saves petrol burnt on idealing ..

any comments ??

 

[alexklg]

To me, let it idle for a while, (1-2mins) then drive slowly until temp reaches 1/4 of my gauge then i drive normally liaoz...

XD

Like my car..since the auto choke has failed..it will idle at 500rpm..ones it is warmed up..the rpm will go till 800-900rpm..then i drive away..which will take usually 5min.cheers.

start my car, open de manual gate of de houz, get into de car n slowly reverse out from de car porch.. idle running about 5 mins like tat lo.. :regular_smile:

 

[nitrus]

u all were speaking about a gauge that u all check for the temp ... what gauge is that?
