Diffy Fluid Thoughts

[1985 CCX]

I am about to change my differential fluid in my Jag rear. What is the best fluid to use for such an application? Should I go with 80-90w gear lude with limited slip modifiers or is Mercon V type now the accepted lubricant?

Thanks

I asked the same question repeatedly and the consensus I got was Moroso Climbing Gear Oil and two tubes of GM limited slip additive, both available online through Jegs. I learned later you can 'tune' by varying the amount of limited slip additive you use by adding an ounce or two at a time until it operates smoothly around corners but I have not tried this. No complaints about the Moroso and GM combo in my Jag Powerlock.

Ditto the Moroso Climbing Gear Lube and the limited slip additive for the Slisbury rear end.
