Canadian Tire here has Motomaster Formula 1 0W30 Winter Syn. Blend on sale for $1.49 (reg. $4.99) per litre bottle (actually 946 ml). I noticed it was SJ rated on the back of the bottle(?) and the date of production was Nov. 2005. Worth buying? It hasn't been that cold here, but would it be a good idea to buy since it's such a good price and add to "the supply". The Motomaster oils in my opinion are very good (re-branded Shell) that I always use, but the SJ has peaked my curiousity. Vehicles are a 1999 4.8L Silverado - 185,000 km and a 3.1L 1997 Lumina - 70,000 km.
