didn't plan on changing fluid and have redline mt90 around, and lost the receipt. just wondering if it would be okay to use the mt90 instead of the 75w90 in the lsd instead. let me know.

thanks in advance,
steven

 

MT-90 is a 75W90, but don't forget that if you have a 86-88 you should use a LSD additive as well.

 

i would HIGHLY recommend that you use Fords limited slip additive. Good stuff cheap.

 

ah, you need an additive if you change the 86-88 lsds? man.. good thign i didnt change the oil yet

 

Get a bottle of Redline Friction Modifier and add it to your oil. Or just get the Redline oil that already has a 5% mixture of the additive in it. This is what I will be using on my Kaaz LSD in my 1991 TII.

 

i just went ahead and bought the 75w90. didn't have anything else better to do today. thanks for the replies.
