This is for my 2011 RX-8.
The only thing I know right now is that I do NOT want Red Line or Royal Purple.
I'd use a Mazda fluid, but from what I'm reading they only sell SAE 90 or 80w-90; 75w-90 is permitted but not sold by Mazda.
I was looking at Motul Gear 300, but I don't know whether I need a type made for hypoid gears.
Any suggestions?
