Best Fluid for Manual Transmission
I was looking to change the fluids in my '07 GT. What is the best fluid to use for my manual transmission/gearbox?

OEM fluid, and change it every 30k. My original trans had over 143,000 miles on it and is still running in another RX-8. I only pulled it to switch to a Series II trans with 9000 miles on it.

Stick with one of the known ones:
- OE fluid from the dealer
- Redline MT90
- Eunos
Avoid Royal Purple, it's not the right type, it will destroy the syncros. Many other store available brands are just as bad. It's not worth experimenting with.
