How long do you warm up your car for?
Guess it's a bad time to mention that it's 80* again here today eh?

I live in CA, I think the oil still works as intended with 0w-40. I have a Porsche 997 I daily drove for 5 years that I did the 10 second warmup on and then I'd take off, and it's still kicking. Mercedes easily builds as good engines as Porsche in my experience, and the early M276 and M273 stuff was rectified and or coincidentally just works to this day. I just don't like to romp on it too hard until the transmission oils get to proper temp otherwise it shifts poorly.

So for me I usually do 30 seconds. Then I am off. If I leave a car outside in extreme conditions (Left my CLK outside when it was -10’ once) I would turn the key to the accessory position first and then wait. Then start it and let it idle for about a minute or two.

Old thread. But if the wife is driving, get in, go. no matter the temperature. Does not make me smile.
I wait at least 2 min in sub 40 degree weather with all the cars.
Never do any spirited or highway speeds until the engine is at NOT

No need on modern cars....it will warm up faster with a light load on it (so driving it) than it will just sitting on the drive. I just start my cars....seat belt on, glasses on, then drive. The longer you sit still the slower it is to warm up and the longer its injecting more fuel to keep running....this in turn washes oil off the cylinder walls causing more wear long time. I'm not suggesting you red line it from cold but starting and driving very gently for a mile or two (I never go beyond about 2500 rpm until the water temp is up to its normal fully warmed point on the gauge anyway) is better than letting it idle. Might be a bit different for you guys living in Canada or other really cold places....but I live in the South UK.....hardly ever gets below 32F!
