If you find the stone clogs quickly when used dry or if used with just water, then it'd likely do better when used with oil.
Being it's a natural stone, there's no rule as to which should be used. But the key point is, it may work a lot better if used with something that keeps the stone from clogging. Sometimes water won't do that very well on a stone that doesn't shed much grit. In that case, using oil almost always helps it work better.
Other 'natural' stones that shed grit readily, like sandstone or siltstone, can work great with water. But otherwise, oil is probably the way to go.
