GL-5 plus
I am changing the diff fluid in my 10 bolt diff. i think i dont have a posi so will the GL-5 Plus which is for limited slip diffs hurt mine. or should i just return it and get the regular GL-5 diff fluid. it seems to me that it wouldn't hurt to have an extra additive but who knows.

I bought limited slip additive for mine because i thought i had posi. But i changed the fluid and i didn't so i added the additive anyway. I havent had any problems yet and dont think i will.
