Transmission & Diff. Drain and Fill
I have a 2004 Rx8 manual transmission with about 80,000 miles and I am wanting to change out the transmission and differential oil. I have heard so much talk about what kind to use and I was going to go with the Royal Purple Max Gear 75w90 gear oil in the transmission and differential. I would appreciate any input on this.

As far as the differential goes, instead of doing a drain and fill take it apart and clean it. Its really not all that hard. You will need a new gasket and it will take longer, but you can do a really really good cleaning job that way. Redline will actually make a recommendation for you on these but I use Heavy Shockproof Gear Oil from redline in my transmission and its still working just fine, along with 75w-90 GL5 redline diff oil. But again you will only be able to make this decision for yourself to see what works best in your eyes.
