just out of curiosity, how long on average do you take to warm up your car?

i take at least one cigarette time to warm up (10mins approx), that is when i see the oil temp needle touches the first white line and my rpm sits around 900.

i feel that it's a little long, and it doesn't help when i'm rushing to school. been considering a remote start too.

comments?

p.s i drive an R33 GTST M-spec

Some people advocate waiting a few moments after starting the engine, not to warm the car up (this can be done while moving) but to ensure that the oil pump has been given sufficient time to circluate oil around the upper block/head/cam area.

Personally, I always give my car a minute or two before moving off, then take it easy until the temp has reached normal.

sometimes if i have time i let the car start and while i'm getting ready or grabbing a bite to eat before i go out let it sit thier..maybe 5min-10min dont usally have time to do this anyways. But on a average day start her up..let the oil pressure go fully up to where its meant to be after it starts...maybe pop a cd on. Reverse it out slowly on to the road...then do a couple of laps around a couple of streets around my house...keep it at the lowest revs i can...then head to the main roads to my destination. Letting the gearbox warm up abit and diff etc. I usally take it easy untill my oil pressure is up where it should be. Then increase my rpms... :P

Yep, with turbo cars it is particularly important to give the oil a few moments to reach the turbos (which are usually high up on the block, thus being one of the last components to be lubricated after ignition)

I think the main point though, it that there isn't anything to be gained by letting your car idle for long periods of time before moving off - the engine will warm up just as quickly when you're moving and standing still isn't doing anything to help the gearbox/transmission oil warm up...

I generally only have mine running for about 30 seconds or upto a minute, anymore than that is a waste of petrol and time.

Like the other guys said - go easy for the first 5-10 mins of driving but wouldnt personally sit there stationary for that long.

I use my Oil Temp [factory on 34] gauge to work out when I can drive a bit harder :P If the oil temp is cold, you dont wanna drive hard.

Also use your last 5-10mins of driving to cool the car down after a fang, then you only need a short amount of turbo-timer - again I use my Oil temp guage to workout whats needed.

Sorry got a bit carried away, hope all this helps :)

yeah what nismo said is all true . i usually let it sit particulary on a cold mornin for about 30 seconds , drive it slowly tring to keep the revs under 2000 . then after about 5 mins i look at all my guages especially oil an then go for it but 5mins is generally all u need no need to idle for that long a period , it would be a waste same with cooling if ive been thrashin it all the way home

then the TT takes longer, but if i say drive (normally) for a few mins after then it doesnt take long at all , and i think is better for the engine then rather switching it just off

crooser just in case u didnt know the g/box turns while the engine is running and the car stationaryas long as u dont have the clutch pedal to the floor , thats the only time the box is not turning .

redline gtir oil starts circulating the minute u start the engine if it didnt u r engine wont last long . i take it easy when i first start the engine though , never any amount of boost until the coolant temp goes to normal , for the oil temp to get to normal it could take up to 30 minutes though and the harder u drive the hoter the oil will get . u dont have to have oil temp to 140 to give it hard on full boost or high rpm though but when it comes to turning it off then u must make sure u cool it down a little like driving with no boost or idling it at home for a 2-3 minutes , that way ur turbo will leve longer .

demon dave the turbo line is always full of oil so as soon as u start the engine u got oil circulating the last to get oil runing are the cams and the valve stems .

nismo 34 thats fine but it usualy takes that long to back out of the drive so as long as u dont have to back up a steep drive ( puting load on the engine ) u can start and back out .

mark r33 sure drive at low rpm say to 3- 3500 but more impotantly dont load u r engine ( high gear and low rpm ) until it warms up . one part of the engine that doesnt get lubricated when u first start is the cil bore thats when most of the wear happens when u first start it ( the first 30 - 60 seconds )

even if i've been driving along heavy traffic when i stop the car i always idle the engine for a few seconds before turning off .

I personally warm the car up until the temp needle starts to move then I take off and drive carefully until the temp needle is at normal operating temperature.

I know most would think it's a waste of time to sit there for 10 minutes waiting for the car to warm up, but it's just one of those things I do to look after my car as much as I can. (not saying you people don't look after your cars).

I also adjust my turbotimer to the approriate amount of time for the drive I just did. (don't know why I added that :-) )

my two cents worth anyways...

its a waste of time and fuel to warm cars up before driving.....u just have to take it easy , i.e dont load the engine or drive at high revs until oil temp is at operating temp, which is about 30 mins into driving...

then you can let loose...:D

personally if i had the time i would let it idle after startup for 5min max and then drive off slowly...but still knowing that there is some heat already in it.

Basically...drive it soft untill desired temp is reached.

Use a good quality oil and a specific rating for cold starts.

Dont push your car untill its ready...unless u want to waste money.

geez i question the credibility of some of these responses...

how can anyone justify starting and driving immediately? its physically impossible for oil to magically jump from the sump to the top of the engine as soon as you start. there has to be a period of wear unless oil can reach it.

surely there is advantage in leaving you car running for 1-2mins just to move some oil around then drive slowly as said previously...

and if you worry about fuel consumption then

1) you're a pov

2) the way you drive determines your fuel usage not warming up / cooling down. the amount of fuel used at warm up is negligable...

...and the sensor for oil temp is located down near the sump so that is not always the best indication of oil movment (my oil pressure rises very quickly after starting)

but this is only my 2c and you can do what you like...

oil starts circulating immediately when the engine starts....although very briefly(seconds) you get no/low oil pressure after starting...thats when the damage occurs and no matter how long you warm the engine, this will happen every time you start your engine....why do think taxi's get such long engine life??? coz they rarely stop their engine during their shifts...

secondly there is waste of fuel if you let your car sit there for ten minutes to warm up everyday particularly because the engine will warm up quicker if you are driving it in that ten minutes.....not only will you waste time(precious for some of us) also waste fuel because of the longer standing warm up period and as the engine runs richer during warm up , it will emit more unburnt fuel to the atmoshere which is bad for the environment...

so not only you are wasting your time and money, but also you are exhausting the fuel supplies and adding to the pollution.. :)

thanks guys for the enthusiastic replies, i do appreciate them, i think i'd take less time to warm up my car from now on, but i still feel that starting the car and driving off is going to do mechanical harm. don't forget, it's a 10 year old car, and it's winter.

maybe i'll time the warm up a little under 5mins. and keep my turbo timer on for 1-2mins after the first start up.

cheers! and happy driving!

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
