> albertas oil sucks. takes too much effort to refine it. you don't know what you are talking about. there's more than one grade of crude from alberta. each grade has advantages and disadvantages and refiners optimize their refineries around the blends that are most available with the best value outputs. it's a very complex chemistry and market. most people haven't even heard of the 3-2-1 crack spread. $crack321   3-2-1-crack-spread/
