MT-90 Bad for Warranty?

MT-90 Bad for Warranty?
Hey guys,
My transmission is beginning to exhibit a few of the known problems, most notably a difficult 3-4 shift when redlining prior to changing gears. The transmission is still under the Mazda warranty. I'm running Redline MT-90 in it. My question is, will running a non-stock / synthetic (vs. factory dino) oil possibly void the warranty on the tranny?

My dealership was really confused by the purple gear oil in my tranny (Royal Purple MaxGear). After swapping in the Mazda designated fluid didn't fix my problem (grinding going up or down into 5th when warm at over 3000RPM), they rebuilt my transmission under warranty.

max gear was ur problem, its a gl 5 fluid, it supposed to work with gear box that needs gl4, usually, this is not the case, but rp probably added something to it and it works in their lab, but i guess its still way too slippy for synchro.
and tricky part is, is pretty hard to prove that the fluid is not good, so its better to just avoid it
rp makes great engine oil tho. i use them and its good, just a bit expensive. 20w50 baby
yep, it will, gear box will not see too much contaimation so the fluid will mostly come out with the orignial color unless you drain it after 60 k miles. i tried rp before so i know(big mistake, lucky i drain it out before it fuckx it up.) its a great gl5 fluid for rear diff, just not gear box

You're right, this will probably work. But the scenario I was envisioning is this. Mazda NA would agree to replace the transmission or pay for a rebuild and then keep my old parts, as they always do for warranteed work. I assume they keep the failed parts for R&D. They send the parts to a lab, where I'm sure it's easy to test the oil residue, they find out it's a non-OEM oil, they send me the bill. Depends on how uptight the car company is and I'm sure Mazda gets a lot of RX-8 trannies on warranty claims. I haven't dealt with the dealer for big warranty work yet, so that's why I came to you guys.

I don't that they would go the extent of doing research on the oil residue, this isn't the OJ murder mystery to determine what killed the tranny.
If they do it is a waste of money and time.
I do believe they will rebuild the tranny and that's what you should expect to see in your car as well.

Even you use Non-OEM oil, Mazda couldn't make u pay for it. As long as you did it right in the first place(use the proper oil) and they can't tell the oil by examining it like that, cuz all oil has almost the same stuff in them, some will have some "secret ingredient" in them to make them work better, but there is no way Mazda would know.
I dont even know if there is any "official" transmission oil from Mazda for sale anywhere in NA. Rx-8 aint GT-R you know.

In any case, I just opened up the service manual to the page on transmission oil and it simply states to use 75W90 GL-4 or GL-5. Nothing about synthetic or otherwise. MT-90 meets those specs, so I think Mazda will have to honor the warranty.
Thanks for your input, guys.

Microscope can't help them in that case, we're not checking for viruses. They need to check the properties, which is even harder, consider there is always some "left over" oil inside the tranny.
My main concern was the synthetic oil being a problem, since I've heard all those marginally accurate warnings about using synthetic in rotary engines. I thought it might somehow influence the transmission warranty.

They will, and have, sent trans oil out to be tested for weight if they think something is wrong, claimed my GF's RX-8 had green 40W oil in the trans after it was sent out and tested, refused to warranty it so I installed a used one and we'll never step foot in the only local Mazda dealership here ... total BS
but it shouldn't matter with MT-90 since it meets the specified oil weight requirement

oh it gets better, a month earlier she paid them $1000 for replacing the clutch because I didn't have time and they swear the oil was never touched
the clutch disc came apart i.e. the hub rivets all separated and the disc, springs, etc. were all loose, that wasn't a warranty item either
I'm hoping the company that owns them goes bankrupt soon ....
