But, A3/B4 would be my consideration here, considering that's one of the easiest ways to get a 0w-XX or even 5w-XX with good Noack and a sensible price.
Now, the original poster is in Canada, so mail in rebates and oil at $2 a quart aren't even on the radar, but a jug of M1 0w-40 or Castrol 0w-40 A3/B4 at roughly $30 is on the radar. He'll have a hard enough time finding a 10w-30 synthetic on the shelf reliably. Our Canadian Tires don't even stock any of the Shell 10w-30 synthetics, nor do they carry it in Castrol gold bottle.
As for a failure, I tend to run the exact same oil for very extended periods of time. Mobil's warranty doesn't have a prorating provision or shared responsibility provision with Shell or Valvoline or Castrol. When you mix, you're on your own. The oil companies don't guarantee mixes, aside from API miscibility standards. As I mentioned, when I have a vehicle that consumes, I carry some in the trunk. If I didn't, of course I'd add wherever I found oil. That doesn't mean I'd put in five different branded litres at an oil change.
When I had my LTD, it burned a whack of oil. I always had at least two litres of GTX in the trunk. The F-150 used to leak a lot, and I always carried top off until I got the leaks under control. Living in Saskatchewan sometimes means being miles away from an open gas station, so carrying top up is prudent, as Shannow indicated. I've never bought top up at a gas station in my life, and the LTD could burn 1 litre on a 150 mile highway drive. I was simply prepared.
As to finding out something you just got is an oil burner for the first time, you probably don't know what's in the sump anyhow. So, if it were me, I'd do what I always do. I change the oil as soon as I buy the vehicle and buy a couple extra quarts because I'm used to vehicles burning oil.

The person mixing will. The oil companies certainly would not.
What do you want to improve about the winter rating system? Do you know of a test that we don't? Pour point was eliminated for a reason, and MRV brought into the picture for that very reason. What weaknesses do you see in the winter rating system?
It's never failed me. I choose a 5w-XX or very occasionally a 0w-XX in the winter, and it's served me very well, and we get a real winter here. I've never been steered wrong choosing an oil based on the current winter rating system.
