I've tried several methods of dispensing oil on my SB9 ways, usually involving a chip brush, that results in smearing a mixture of chips and oil over the ways.
While cleaning off my desk, I came across a little bottle with a sponge on top, normally filled with water and used to seal envelopes. As it left my hand for the trash can, the little light came on above my head.
Snagged it back out of the trash, filled with oil, couple of squeezes. Works good. Don't know how it would work with actual way oil. My machine is pretty worn, so I just use motor oil on the ways.
