I have to give Canadian Tire a backhanded compliment, though, with their latest QSGB special. The did have enough stock scattered throughout the store that there was plenty to buy, if I were so inclined. Their main QS shelf was an absolute joke, though. I have a picture I'll have to download and post. There was one column of oil for 5w-30, and about four or so for 5w-20, and about five or so for 10w-30. Of course, the 5w-30 was cleaned out, because that's a commonly used grade. 5w-20 is used, but they had plenty of shelf space for it. They had enough 10w-30 to choke a horse, though. 10w-30 isn't on the top of my shopping list for Saskatchewan winters (or summers, for that matter), and no one specifies the stuff anyway.
