As has often been said, what it states in the handbook!
140k is nowt unless its been hammered, and if it has been hammered that hard, the damage is done.
If looking for more protection and your engine uses A5/B5, you can use A3/B4 instead, and/or xw40 instead of xw30, but you dont need to.
Maybe this might be of use
