Half mineral oil, half kerosene.

=============================

Actually not, at least not any more. I once damaged an expensive
sailboat compass by refilling with alcohol, only to watch the entire
interior of the globe turn cloudy. It turns out that the correct
fluid is a very clear, low viscosity petroleum based product which
looks and smells suspiciously like white kerosene or mineral spirits.
Some manufacturers reportedly use a silicone based fluid however which
is incompatible with kerosene or mineral spirits. Best advice it it's
a good compass is to contact the manufacturer and get whatever they
recommend.
