Drivetrain Limited Slip fluid?

I’ve done some searching and haven’t really gotten an answer. I apologize if it’s beating a dead horse, but do you need the friction modifier from Ford if the fluid claims to be limited slip approved? Mobil 1 synthetic LS. My thought is just to put it in, I already have the stuff, but I don’t want to overdo it. I don’t think you can really over lube something, but some things need a bit of friction to work right. (It was really hard to type this without giggling just a little bit)

You do not need the friction modifier if the oil you are using already contains it.

Oil that is approved for wet clutch use will be marked with: JASO MA in the list of ratings/specifications
