Surprised to find Amsoil at Can. Tire this weekend. Only the 0-30 (Series 2000 - Heavy Duty?), the 5-30 and 10-30 grades. $11 and change for the 0-30 (back of bottle suggesting 35k mi./1yr changes) and $9 and change for the other 2 grades (suggesting 25 mi./1yr changes). Found at the Dundas/403 location.
