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 use neo. pretty good stuff

 

I use AMSOIL symthetic gear lube.

 

read the bottle hehe. my royal purple said it right on it...LSD compatible.

 

I used Royal Purple 3/4 DOT. awesome

 

HEY look who failed reading comprehension....

i didnt even think to look at the bottle lol.

it says contains addatives for limited slip differentials.

thanks for all the input

 

 

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



I'll get some real oil in it soon!

I wondered if i hurt something?

 

i haven't gottin this far in my restoration where can i look to find out if my car has the limited slip or not

 

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.
