So, I think I messed up. But, I thought I'd ask here before I make a mess to correct my potential mistake.
So, I just got done cleaning/painting my Firebird rear end as well as replacing the gasket on the diff cover. I put in limited slip additive and followed with the appropriate amount of Lucas gear oil https://lucasoil.com/products/gear-o...0w-90-gear-oil.
Shortly after I did that, I came in to order some more gear oil(to have on hand) and read something that either wasn't on my old label or I had merely overlooked. It says "Excellent for use in limited slip differentials". That would lead me to believe the additive was unnecessary.

So, the question is this: Am I going to eventually harm something by essentially having too much additive? Or will the posi just not work as well as it should?

Also, if this makes any difference, right now it is a stock 400 but I have been considering installing a much healthier 455.
