I don't think I'd use MsO(2) to coat the bore and pistons during assembly instead of
oil. Or, would you?
What would Castrol know about
oil? Well they recently WOKE UP and smelled the coffee and created a NEW (or would that be OLD?)
oil specifically to address the flat tappet cam application (again, like they used to). 'Modern' aint all that all the time. Does Ford even make a flat tappet motor anymore?
