I am trying to find some fluid to put in my Limited Slip. Suggestions on what to put in there until I can get some redline sent to me. Will Royal Purple be ok?? It does not mention anything as far as I can tell about friction modifiers which I seem to need for my LSD. Any help or suggestions would be much appreciated.

Royal Purple is highly recommended by Racing Beat.. although I have spoken to many professional RX-7 racercar builders and they have told me that unless the differential was first built and has had a synthetic gear lube from the beginning to NOT use it.. took me 3 diffs to go bad (each of my street RX-7s over 12 years) to finally simply use cheap fluid with an LSD additive.. you choose.
