Just wonder is it ok to use Eneos 75W90 in the Rx8 limited slip diff. Can't find a definitive answer anyplace. Just put in the trans and it does seem smoother.
Thanks

Yes, you can use that in the diff.

 

i have it in my diff and trans w/o problems

 

Same here, been running Eneos 75w90 in both trans and diff for about 10k so far and no problems.

 

You can use any number of 75W90 gear oils that are available locally. Not sure why you are only interested in that particular one?

If you ever need manual trans fluid then you might want to google Motorcraft XT-M5-QS, which is usually available at any Ford dealer. The Miata owners turned me on to that one, it really is the smoothest shifting trans fluid I've ever used. It gets high satisfaction ratings by all enthusiasts and racers.

 

interesting.

I'm looking for some tranny fluid as well, hmm, it's hard to get this @ where I live now, maybe I should order a few and ship it over

 

I have a case in the garage. Just let me know and I'll get some out to you.
