Limited Slip Additive

[Bob S]

Does anyone know if Mobil One has a limited slip additive in it?

I looked into this when I had my 951 with LSD. The answer I got from Mobil's web-site was "typically no friction modifier is needed when Mobil 1 gear lube is used in LSD differentials". Of course the important word in that answer is "typically", under some circumstances a friction modifier probably is needed. In my case the Mobil 1 gear lube seemed to work fine in my 951's LSD (and yes, the LSD worked fine also).

Thanks Jerry. I'm going to try it in my G50.

I have a 915 w/ factory LSD. I'm using Swepco. Do I need an additive, or is Swepco alone good enough?
