Oils Well That Ends Well, Part 2
This photo of two oil samples before and after the heat test shows how some of the Group III synthetics are now using better-quality base stocks. The two top tins show Castrol Syntec automobile (left) and Motul 300V (right) before the heat test; the two lower tins are both oils afterward (again, Castrol left, Motul right). Note the similarity in color between the oils in the post-heat test samples.
