What is the preferred sythetic geat lubricant for the manual transmission? A
local RX-7 hot shoe advises using Red Line MTL. My concern is that this is
75W80 instead of the 75W90 called for in the owner's manual. The Red Line
75W90 has hypoid additives, great for the differential but I not sure about
using it in the transmission.

Any recommendations?
