987.2 PDK Diff Oils

[Wayne_oz951]

Hi Everyone quick question, I see the diff oil for a PDK car is just listed as a 75W90 fairly common oil, my question is does having a limited slip diff option make a difference? Does it require a different oil?

I haven't done either of my Porsches yet, but on my Fox-body Mustangs, it would require a friction modifier additive, and boy, did that stuff stink!
