Moser wants you to use a non synthetic gear oil. Napa 80/90 weight non synthetic gear oil does the job. As has been mentioned, pick up a tube a posi additive, some call it friction modifier. Bob

With the Eaton Posi you will want to use non-synthetic 80w90. Any decent brand will do. Also pickup a bottle of GM #1052358 from a local GM dealer. Trust me when I tell you to get the GM brand Limited Slip additive
