Proper Warmups

They actually say "two hours is usually enough".
Which is false. I run equipment in the winter and diesel trucks. When it's -20c or more, 2hours isn't enough. I've felt the block after two hours and it's usually not warmed up much past the element. I do a min of 3-4 hours before I can feel some warmth on the block and that's a small 3 litre Diesel engine.
If I leave the block heater on over night when it's -20c or colder. I can start a diesel truck, let it idle for half a min and drive away and it will start pumping heat quick. Without it or for an hour she is cold for a while.
When it's bitterly cold out, the worst thing you can do is start a cold engine. The block heater helps huge.

That's a tough situation with no car insurance during that period. Because if you are storing a car for the winter, the best way to avoid flat spots, etc. is to simply start the car up and drive it around the block for a few minutes.

If you're storing the car, just don't start it unless your going to drive it. I wouldn't be too worried about flat spots in the tires either, since tire technology has advanced to the point that a few months sitting will not cause them to lose shape. If you want to be sure, you can overinflate them.

Yep easy to say when you're living in California.
Tuesday morning, -30c (that's -22f for those still living in the dark ages ) car was completely frozen due to a mix of fine hail and freezing rain we had the day before. I let the C63 idle for a while.
Would I let the car idle for long period of times, all the times? No. But -30c on a completely frozen car, well, even if I wanted to drive away shortly after start up, the car was still covered in ice.
The CAA says to let idle from 1-2min in cold weather before driving off. No hard acceleration before the car is properly warmed up.

How does the C63 cope with the -30c starts and driving? Just curious. Ive never had my C63 out in that much cold.
I remember my old G35 I had it idleing for like 20 min straight in Fort Mac and drove off to the highway and it was still so dam cold I could barely shift it lol.

Although my tstat is starting to give me problems I want to say she's fine in the cold weather.

Remember, block heaters are recommend only when it's colder than about -15 to -20 C. You're looking to warm the internals via the coolant. Just because the exterior feels cold to the touch doesn't mean the heater hasn't done its job. The internals just need to be out of the deep freeze, the exterior doesn't need to be warm. An engine with internals at 5C would feel very cold to the touch, but would be just fine to start.
