Plus 4"s also got the LSD. I think it's more common than you might think.
Thanks for confirming that Dave.
The worrying thing for owners though is that the owners handbooks seem to be generic so people could unwittingly change their diff oil for one without LSD additives…unless they check first!
As the additives do not appear to upset an open diff. seems that it is best for everyone to use the LSD oil to be on the safe side.
