Red Line synthetic fluids

[locski]

from what I have gathered, this is what everyone is recommending?

Tranny:  MTL over MT-90?

Differential:  Heavy Shockproof over 75W90 & 80W140?

What about their synthetic power steering fluid?

Thanks for the input.

I'd love to know this too.
The 240sx.org says 75w-140NS Redline for the tranny and 80w-140 Redline for the differential. So, who knows.
I guess it really depends on your synchros. I think really thin stuff is bad for old synchros and the synthetics can leak through old seals. So an old tranny id more "picky" than a newer one.

For tranny fluid I use MT-90 and works fine for me. The shifting is much smoother. I haven't used the other stuff, so I can't help you out there.

Don't use the shockproof for the diff....

In my FD and in my S13 i used light weight shockproof in the tranny and 75w90 in the diff.

Thanks for the replies.

Just spoke with the rep from Red Line.

Tranny:  MT-90
Differential:  75W90

I will give a report when I am done with the switch.

Yea, I used MT-90 in my 91 Hatchback and Lightweight Shockproof Oil in my 95 KA-Turbo.

I never got around to putting it in my diff, but 75-90 is correct.
