WHen I got the car on the road on june 30, I filled an empty gearbox with hypoid 90 oil. Based on what I have been reading this was a mistake. How corrosive to the workings of the gearbox is this oil, how soon should I change out and when I change it out for 20w50 do I need to flush the gearbox with something ?? or just run it get it warm and then drain and change??
