No doubt good injector and strong battery help in our Canadian winters.

I now use Mobil 1 TDT 5W40 in my 85 300D. For winter starts, it has (I believe) a much lower pour point or MRV @-40 that 15-40 oils. When you first start the car in winter, with higher viscosity oil you may not get the required lubrication, just when it is most needed.

In the USA, at Walmart, Mobil 1 seems to cost $24.97 for 5qts regardless of which Mobil 1 I buy. I usually stock up when down there in the winter. Canadian retailers just don't seem to get it!
