    No limitit slip additive on g80 locking diff!!!!!

    Yes actually if you add the limided slip additive you can lose use of the locking part of G80 locking rear diff. I even have the shop manuals and i looked it up to be sure and it says plain as day DO NOT ADD limited slip additive on locking diff. the lubricant makes the locking mechanisim and clutches too slippery to lock up. I hope this helps i just didnt want anyone to mess up their diffiental by adding that stuff.
