If you look on the API site, it seems that Canadian Tire is not an approved licencee on motor oils. Therefore, all their oils, from Formula 1 all the way to Autolab are illegally using the API donut.
I know these are Shell oils, and the Shell oils are certified, but if you got an oil change done with a C-T oil, and your car was under warranty, would this cause a problem if you went for a claim? I've gotten my oil changed there once, and was thinking of doing it again, but if there is a risk involved, seems pointless!
