Most any oil will be better than nothing. The hydraulic oil may evaporate faster than Way oil.

I do not expect you will be using the crane for hours every day, so preventing rust is probably your prime concern. If you have any cosmolene you could add that to some hydraulic oil and use that. Or if you have a pottery supply near by you could get some Microcrystalline wax and add that to hydraulic oil. Essentially the same as cosmolene.
