Sorry but I search but I did not find an answer to my question, I am sure that has been touched on before

1936 120

Bought SAE 80-90 GL5 for my trans, steering box etc. It says that I should use GL1. Can I use this?

Bought SAE 85-140 GL5 for my differential. It says that I should use GL1. Can I use this?
Thanks again
Will
