Are there different viscosity 'scales' for the different types of oil?
The 'straight' SAE50 mineral oil I use in my Burman and AMC gearboxes is much 'thicker' than the 80w90 EP multi-grade oil that I use in my Triumph gearboxes... at room temperature, at least!

Yeah, I believe so, NGLI, SAE, etc. etc. As far as I can tell, it's like buying audio equipment with it's "RMS" values.

How much oil should be used? The burman manual I have talks about 2-3 ounces of grease, what might this be in oil? 🤔

Hi
I'm not sure what manual you are referencing but the 55 singles manuals tell you not to use grease but 1 pint of their recommended oil.

Grease was only used in the earlier Burman CP boxes and it was not really a grease a sort of grease oil mix.
