Awesome replies! This is why I started this thread!
I usually go out and remote start it and let it run for 2-5 minutes atleast, usually waiting until it hits 100 deg. I had concerns/ideas regarding a cold start and the oil not being warmed/circulating and what that might do further down the road.
Thanks for the input guys

i did some research and it takes average 30 second to make the oils circulate everywhere.....after that its useless...
here some facts from the government of canada.
•An idling engine releases twice as many exhaust fumes than a vehicle in motion.
•If every driver in Canada avoided idling for 5 minutes a day, we could prevent 1.6 million tonnes of carbon dioxide from being emitted.
•No more than 30 seconds of idling is needed for oil to circulate through your engine. Many components, such as the wheel bearings, tires and suspension system will only warm up once the vehicle is moving.
•Restarting your car many times has little impact on engine components, adding only around $10 per year to the cost of driving, money that is recovered in fuel savings.
•Ten seconds of idling uses more fuel than restarting the engine.
•Idling can damage your engine since it is not operating at its peak temperature where fuel is completely burned. Fuel residue from incomplete burning can damage engine parts.
•Idling a vehicle for 10 minutes a day uses an average of 100 litres of gas a year. If gas costs 70 cents a litre, you will save $70 per year, just by turning your key.
•During the winter, Canadians idle their vehicles for a combined total of 75 million minutes/day. This is equal to a vehicle idling for 144 years. Although we idle our vehicles about 40% less in summer, we still waste an enormous amount of fuel and money.
•A block heater warms the oil and engine coolant, making it easier to start your vehicle and improving winter fuel economy by as much as 10%.

theres no doubt there is EXCESSIVE idling in canada,
but that is not 100% due to warming your engine up.
that refers to the millions of people who LEAVE it running when they go to a store instead of shutting it off.
btw, if people stopped eating beans we could probably save 10 times the amount of emissions,
that al gore and david suzuki rhetoric can suck my idling tailpipe. my car aint moving on cold oil.

well this post just gave me chance to think about getting a block heater before this winter.....

I warm mine to 75-100*F depending on how much of a hurry I'm in...I try to shoot for 100 though. Seems to be the general concensus. I just hate when I first start my motor and there's all that ticking, so I let it settle down a bit before I go anywhere. Perhaps I should have them look at the timing chain. I know ecotecs are noisy, but this is out of the norm.

Anything more then 5mins is to long. It does not help starting it and letting it sit for longer then 5mins. Even if its real cold outside 5mins is plenty of time. If your in a hurry I would still let it warm up for at least 1-2min. When its hot out I let it run for about 1min to. To answer your question...
Parts are cold from it sitting. Cold parts wear quicker and you should give the engine time to get to a good running temp. This also moves all the liquids and lubs everything before the engine rpm go higher then idle.
You would gain so much +rep from me for that statment 
Rep is gone though..

the fact that you guys "technically" think theres no benefit to warming up your car is scary.
who "technically" told you that one?
go get a bottle of mobil 1, cool it down to a nice chilly early morning winter temperature, and pour some out of the bottle, then compare it to some nice heated oil.
no benefit. BAH. what are dads teaching their kids about engines these days.

I agree with statements on both sides....I think that newer engines, with advanced coatings, oils and manufacturing processes, modern engines are more suited to running "cold". Having said that, I always wait until my vehicle come out of high idle mode during spring / summer / fall. In winter, it can get to -40C and you MUST warm your car up for at least 5 minutes before you drive it...and yes..this is with it plugged in already - you run the risk of a 4-corner seizure of your engine from a piston expanding faster than the cylinder walls. It is common to see that when a car pops an engine up here.

it takes 30 seconds to circulate. not get to operating temp. theres a difference

I have come to the ultimate conclusion that I will no longer warm my engine. My new goal is to back into my driveway everynight, I am going to put the car in neutral and go WOT before I turn the key, the second the car turns on I am dropping it into Drive and hauling ass down my 10 foot drive, jumping the curb and doing 97mph in a residential neighborhood. This way I will not have to worry about the stupid 5min warmup, I will be at work before the 5 minutes is up and everything will be fine...

text start even MORE ftw!
the 100 thing is a good rule to work on.
but its within reason right? like if its a beautiful hot summer day, your not going to need to warm up your car like you will when its in the 20s, or in some cases up here, in the -20s

well, i can explain both really...you want the oil to warm up so it doesnt remain as viscous as it would in a cold state, so your engine is better lubricated and it wont wear out parts or overheat parts of your car when under heavy load.
also, fuel atomizes better in warm conditions. fuel, just like water (imagine seeing your breath in winter), will stay in water dropets if the temperature is too low. this can cause situations where only 20% of the fuel in the cylinder turns into vapor and burns, whereas the rest stays liquid and exits the exhaust.
cars tend to run very rich when cranking, and also run very rich when the engine temp is cold. A lot of engines in below freezing weather will crank with AFRs at 2:1 and idle at 8-12:1, depending on the temperature. I would imagine you dont want to be flooring it when the engine runs cold because since a lot of the fuel isnt atomizing with the air, your injectors are trying to compensate by spraying more fuel. this makes it very easy to run injector duty cycles higher than 100%, and thus run lean/create knocking when the engine is cold
im not positive on these reasons, but it makes a lot of sense to me that this would be the case, and im 100% positive the facts in there are true, such as the cranking 2:1 afrs and such.

well you dont want to just hop in it and drive esspecially after it sits over night. i think its called dry sump? or something where all the oil as dripped down back into the oil pan and there is just a little on the pistons. i ussually just let it warm up to 100 F

theres nothing like coming out to the parking lot at work after a 12 hour nightshift, temp is about -35....-40 with the windchill, theres a foot of snow on your car, on top of a 1/4 inch of frost that has to be scraped from your windows.....
you should feel what the shifter feels like on those mornings.
those are the days when 5 minutes isnt nearly enough to get the poor thing ready to drive.

I usually let the car sit for 1-2 minutes before I leave the driveway. I try not to go past 3500 RPM (in 1st, 3000 in all other gears) or 3 PSI while the motors still cold. What I consider cold is anything below 160* hehe. I don't got WOT below 160* unless it's by mistake, I went WOT at about 154* by accident once. What I do is probably a bit excessive but keeping the car running well is priority #1, not beating that yellow light.
My last car has and all metal shift ***. It also had a 4.6L engine that took forever to warm up (as in no heat for the first 5-10 min). When my hand started freezing to the shift *** I got a little pissed off lol.

its all up in the air right now.
sometime in the next 5-7 years ill likely be moving back to aus.
the novelty of snow and winter has definately worn off lol

yeah the shifter doesnt feel great either (metal hurst) but what i meant was more how the tranny feels, its like moving a stick through playdough.
