who uses royal purple synthetic gear oil
i used it in my s4/na
well... 200 miles later. after i did the swap... i now have my bearings making noises.

i had some one tell me that they have heard not so great things for synthetic gear oil in older tranies.
mine has 180k miles on it
please post if you have had this problem with synthetic messing with bearings

I haven't had a problem with Neo, which is synth. I have it in all 3 of my cars.

What?? thats crazy!
I run Royal P in my tranny on my 83 FB, it runs great. I had a third gear syncro that was jacked up it stopped that problem and I feel a difference in power!
Are you sure its not just the 180k on the bearings that caused this.
PS Turbotime your crazy bro!

I've used it in most, if not all, of my personal racecars, and while I am currently running RedLine in the trans and diff of the GTUs, RP Racing 21 is going in the motor very soon (I'm at about 600 miles on a fresh S5 engine).

I've got redline in my tranny and diff and I knoticed that it goes into gear a little better then before. Or could be the fact the oil I drained out was 19 yr old though.

If you're asking me, he said it made his tranny "whir" and shifting became very clunky.(thats a better word )

I just followed what most of the head hanchos around here use, Redline MT-90. As a matter of fact I just realized my shipment of it must have came in today while i was at work.

i have seen more failures in engines, transmissions and differentials using synthetics than non sythetics so IMO the claims that they protect more than conventional oils is bogus, you can throw up any sheets documenting crap but i will believe my eyes and my past history with lubricants over anyone elses "tests".

ya. rp made my **** better...... but...... it kinda gave my bearings a one 2. i do have 180k miles on my car. engine and all. it was perfectly fine till i got RP in it. then the bearings started making noise.... i guess the racing stuff isnt the best for old bearings like i have.
time for a new one!!!
btw. i'll be the 2nd chick to have a miata gear box in her rx7

Well, like Karack says it doesnt matter too much if you run synthetic or not. In cases where you're synchros might be going in your tranny some Redline MT90 might help them shift smoother.
But you also have to worry on older parts that the Syns might leak through where regular oil didn't because it's much thinner.
