Sometimes it helps not think of it as oil getting thin as it warms, but rather how thick it gets when it cools. 0w-30 in the extreme colds, should be thinner than a 5w-30. So at operating temps, they're the same 30 weight oil, but as they cool one gets thicker than the other.

I don't want to sway you one way or another on brands, but I used M1 0w-30 for the past couple of years b/c I scored a good deal on it at the time so that's the one I've looked at more closely when people post info about a 0w oil. Check out the UOA section for M1 0w-30 test results, even in areas of extreme cold it performs way better then just "adequate".

Again, don't mean to sway you on a specific brand, so let me add this. I recently switched to Valvoline (saving my last 0w-30 oil change for the winter), and the engine is slightly quieter and slightly smoother at high RPMs than it was with M1. But that may be a placebo, or may be a characteristic of the oil, either way I have no reason to doubt that the M1 was protecting my engine just fine.

+1 This stuff has always seemed thin and economical so you really cannot go wrong with it. Good oil at a great price!

PP will be a little cheaper, and is good stuff.
I saw no difference in a cold start last winter on a -10F morning between our '99 Accord on M1 0W-30, our Impreza and '97 Accord on PP 5W-30 and our Forester on GC.
I think you'd be fine with either oil.
Incidentally, the only reason I use 10W-30 at all is that you can sometimes pick it up dirt cheap, so two cars are on it now.
The Forester will get FAR VR1 10W-30 for its next change, in a couple of weeks.

Go over to youtube and type in motor oil cold and ck out the videos. These guys are testing flows at -40 nest stuff to see what flows at that temp. Most of it is in Russian but you will get the drift real fast....

Ford specifies 5W-20 for your F-150. Why wouldn't you use this????

Fresh oil has better cold temperature pumpability than used oil. For the best winter performance, do your oil change at the beginning of winter.
