What oil do you use for the gearbox and diff on a 1256 Viva?

SAE 90 for the Diff, not sure about the gearbox

EP80/90 multigrade is correct for diff, gearbox and steering rack.

Don't use modern GL5 spec, it's too slippery for our old synchromesh systems and you'll get a poor gear change. You need GL4 spec. Millers make a Classic formula GL4 spec which is perfect.
