Personally I think that the differences between warming the car up and just getting in and going are neglible at best. When we are seeing these engines get to 150,000+ miles in more than just a couple of cars with different owners behind the wheel, I don't think the difference is really that important to dispute.

Just my $.02

i got this problem with my 07 too,
since first day i got it from the dealer.

don't worry about it.

Don't forget about the gearbox.
When not driving (moving) the gearbox' oil pump does not pump.
No oil going anywhere, all the cold oil sitting at the bottom of the gearbox.
Only some oil splash lubrication for the primairy shaft's bearings.

Start - wait for 10 seconds - drive (keep it under 4500-5000 rpm until operating temp)
No matter how cold or warm, that way all the parts get to operating temp the quickest.
(and use 0W-30 oil for oil flow )

i guess some people misunderstood my intitial post. i definitely dont recommend driving it hard straight off. drive it gently until its up to temperature. the "warm up" i was referring to as being bad was letting it idle in the driveway upon startup.

3 bars worth are what I use as a gage. I had a Audi 5+5 that had an oil temp gage in addition to water temp. There is always a lag in oil temp getting into the normal range. Somewhere in the past and experience with the Audi you need about 7 miles before all temps are in the normal operating range. Piston engined aircraft are warmed up before flight and those engines are much more critical to cont inured safe being than our auto engines.

Its okay, while reversing I hit a garbage can...lol

Little off topic huh... hope the original poster got his info...

but about this warm up. while sometimes i cant let it warm up for even a few seconds. i would say its a horriable idea to drive your car anywhere near 4 or 5k in the morning... if i have to drive it before it gets past 2 bars then i will basically short shift the whole time and keep it under 3k. which is tough but..

i think rocrfella put it the best and i have always believed this to be gospel.

thats just MY 2 cents.

Lots of interesting theories. So say you warm up your car in your driveway for 10 minutes. Congrats. Your engine oil and water are warm. Now what about your differential? Cold. Tires? Cold. Grease in the wheel bearings? Cold. Trans--relatively cold. Driving slowly for the first 5 minutes warms everything up gradually, not just the motor. To avoid large deltas in temperature, keep throttle position reasonable, gearchanges gentle. Idling an engine to warm it up in your driveway is, as mentioned, is a waste of fuel. Long ago, that might have been true as are 3000mi oil changes, but things do change, ya know.

As far as piston-engine aircraft engines, yes those have to be warmed up. You can't operate a prop plane at 20% throttle (whereas we can do that with automobiles) and expect to take-off, do you? Think about it.

4k rpm max until operating temps are reached. no warm up unless.. . you have a standalone ecu and the car drives like shit unless you let it warmup at least 20 secs.

im with this. 4 k till its warm. But dont idle in place forever. warm it alllllll up.
