Sensible choice. No drawbacks using 20W50 in the gearbox/OD. It is used
as the factory standard oil in several British classic cars. Some oils
may be specially formulated but it is doubtful if they perform better.
They all cost more and are probably harder to get, although getting
20W50 is not that easy either these days.
I have used it in my gearbox for more than 35 years.
