I'm about to change out (first time, just got the car) the differential and transmission oils. I think I've read the relevant threads here to get people's opinions and recommendations, but since there is some disagreement I wanted to clarify/verify...
For the original 4-speed I will use Red Line MTL (GL-4 gear oil; SAE 70W80) and for the diff I plan on using Royal Purple MaxGear (SAE 75W-90)...unless someone can tell me why I should not. Thanks in advance.
