In another thread about Mobil 1 going on right now, someone made the comment about 0w-40, "That stuff thins out to [sic] much." He goes on to recommend Delvac or something else, I don't recall.
I thought that the principal criticism of this brand of oil was that its viscosity is on the "thin" side of the range allowable for the various weights, not that the oil has a tendency to "thin" out. Don't we have pretty good trended analyses that Mobil 1 stays in grade?
