I'm looking to replace the factory fill with MT-90 but I've read a lot about MTL oxidizing parts and various crap. So I wanna know, how long have you used a single fluid? If you switch to Redline, drive 25K, change the fluid again with redline, drive another 25K...count that as 50K.

There is almost no doubt in my mind that you could safely run MT90 for well over 50,000 miles.

Somewhere here I have posted a UOA of MT90 after 25,000 miles of use. It tested excellent. My current fill of MT90 has about 35,000 miles, and I will run another test on it some time this spring.

I'm not really worried about the longevity of the fluid, I'll just change it when I feel the shift quality get bad. But I'm more worried about whether the fluid degrades the tranny in any way, if it has caused any blown trannies, etc

Longevity and degredation go hand-in-hand. Oil testing is about the best way to know. MT90 will not blow up your tranny.

I've had my MT-90 in my car for about 75,000km total. I changed it from stock at 25,000km, drained and filled again at 50,000km, drained and filled again at 75,000km and I'm about due for another change now at my next oil change. I haven't mad any issues with it.
