I just went to get some oil today from my local Canadian Tire in Ontario. I noticed there were only 4 bottles left of M1 0w20 and right behind the 0w20 are 5w20 M1. Did they stop making the 0w20? I like to keep using 0w20 because I was told they are better for winter conditions in Canada. Even thought my mazda3 recommands 5w20.
