ok so i need to change the oil in my rear end, and i bought the oil.

but mazdatrix sells LSD addative, did these come with addative from the factory, and do i need to put it in the rear end?

the reason i ask is cause i heard if you do need the adative and dont put it in it will burn up your clutches.

this is on an 84 -SE

thanks

i use royal purple, which does not require an additive for limited slip.

i got redline, so you think it should be ok w/o the addative?

I'm glad you mentioned that. My rear end has straight GL5 in it.

if it's a GSL or GSL-SE with disk brakes, it has LSD. there is a label on the diff unit which states that it has an LSD.
