Though I understand that both are 0W-40 oils, is one of them "thinner" than the other? Any advantages between the physical properties (not thinking about additive packs). Any plus or minus on the Viscosity Index on either? Does the lower pour point on the Castrol indicate "more" synthetic oil base?
