Hi...I have just received my cnc machine and it has an oil reservoir on the gantry for oiling the ball screws and everything else during operation..what lubricant can i use in this?
can I use air compressor oil or sewing machine or do i have to get something like shell tonna or mobil vactra 2?

I am located in Adelaide SA and finding it hard to get something for it at the moment also a bit unsure as to what is most suitable.

Any help or advice appreciated.
