Neil,My m8 at Ford told me over here they have modified the spec. anyway(too many people in the cold climates were complaining about shift problems)i changed mine b4 the engine swap-used Castrol MTX,when the new engine went in i replaced it with Fords latest spec-it's been less notchy since.(now just wait for that gearbox to go pop!!)Give me a shout if you want the FINIS m8.Dave
