Recently I have had to check my Ruby 4-speed 2-sync gearbox oil level every few of days because of a slight weep from the drain plug. For many years it has been running at a level 19mm below the top of the filler plug hole, and this seems to successfully have avoided a recurrence of clutch slip. I understand from the above posts this corresponds to about 1 pint in the box, though I haven't measured it.
I am checking the level from the top of the filler hole using a tyre tread gauge. When this is adjusted to just touch the oil I know the distance down to the surface, which is otherwise hard to see. If the level is a bit low, an egg cup full of oil brings it up a couple of mm.
