I think I tried both Castrol and Valvoline. Whatever the difference is, it shows.I used the Mercon V replica made by Valvoline to drain and fill the manual trans about 10k miles ago. I can try Mercon V I order online from Ford. I am surprised a slightly different formulation affects performance that much in a manual transmission.
