As vulcanite is a rubber I wouldn't use a petroleum based oil on it, and I don't think you can really revive it by rubbing any compounds into it. But if it is looking tired try some non-petroleum based hand cream, or olive oil, rubbed on with a soft cloth.

Based on my (long) experience in the field highly recommend the chemically neutral so called Petroleum jelly, petrolatum or white petrolatum (99% pure - white) : does not react with any material and is acid free.

Beware of Glycerol apparently similar but chemically different and with opposite properties.

First information here: Petroleum jelly - Wikipedia, the free encyclopedia

cited (Wp) ... There Is a Common Misconception That petroleum jelly and glycerol (glycerine) are physically similar, Because They feel similar When applied to human skin. While petroleum jelly is a non-polar hydrocarbon hydrophobic (water-repelling) and insoluble in water, glycerol (not a hydrocarbon but an alcohol) is the opposite: it is so strongly hydrophilic (water-Attracting) That by continuous absorption of moisture from the air, the feeling of it Produces wetness on the skin, similar to the greasiness produced by petroleum jelly ...

 

Well, finally, summing up:

Petroleum jelly forms a film that prevents the degradation of vulcanite, and, most important, do not reacts chemically with it.
