80W/90 gear oil is in fact thinner (less viscous) than 20W/50 engine oils.
Don't be fooled by the numbers, gear oils follow a different index.  If you
don't believe me I will send you the Castrol bulletins on the subject.  Also
the MGB GT V8, with the same gearbox, was specified to use 80W/90 gear oil
in the gearbox by the factory (and that in 1973)>
