Red Line Gear Oil users....
What i sent to Red Line:
>Differential Size/Type : Limited Slip 3.9:1 gear ratio
>Transmission Type: 5-speed manual
>Issues : I am trying to smooth out synchronizer functionability and
>reduce gear grind in my transmission. Also, I want to put the best
>oil i can buy in my differential.
>Recommendations : Can I use your 75-90 gear oil in both my
>transmission and my limited-slip differential (L.S.D.)?
>Mazda calls for 75-90 in both, but I read that the your synthetic
>75-90 gear oil is for use in racing L.S.D., and not sure if i can
>use in a non-racing application.
this is what Red Line sent back to me:
Zach,
Thank you for contacting Red Line Oil, in your RX-7 transmission I
would recommend the MT-90 in the transmission and the 75W90 in the
differential.The 75W90 contains a friction modifier so could be too
slippery for the synchros in the transmission, Mazda calls for either
a GL-4 or GL-5 75W90 in the transmission and a GL-5 in the
differential. The 75W90 can be used in a racing differential but a
dedicated track car would generally use one of our other gear oils.
Regards, Dave
Red Line Oil
should I do what he said? or use the 75-90 in both?

Dude, Redline might be a good product, I am not sure, I have never tried it. But here is some real world advice. I read another thread here where a bunch of users said that using the Penzoil Synchromesh helps alot. I tried it, as the fluids in the ol' RX needed changing. My first and second synchro was real rough, ground bad, but afterward it smoothed out enough that if I am not shifting real quick it will not grind at all.

Haven't we ALL heard this
I have the MT-90 in my tranny...out standing .... simply outstanding!
Edit - I am impressed with Redline's response to your question. Very nice!

And I go with what the guy from Redline oil says about using Redline oil.

Another plug for watter wetter. I used it in my 88 Camaro with great success. As soon as I figure out where I'm leaking coolant from, I'll run it in my TII.
