Should be fine as long as it’s GL4 and meets Ford IB6 gearbox requirements. @M-Sport fan what is your opinion?

Yes, if you are running a Torsen type diff (which the Wavetrac, Mfactory, and Quaife ARE), it is one of the better fluids out there, overall, for our IB6 transaxles. ![[thumb]](/images/smilies/icon_smile_thumb.gif "Thumbs Up [thumb]")
The clutch plate type diffs (Drexler, Gripper, Cusco, KAAZ, OS Giken, etc.) are a little tricky since most of them require a friction modifier additive to be added to the transaxle fluid if it is not already present in it on the shelf.
Most gear oils in our specced weight/viscosity range do not have this additive in them from the oil companies.
