We've seen a case where the glass was dirty, but the oil was there, so make sure it's not overfilled or dirty if adding oil doesn't make it show.

Adding oil

Sorry, I didn't explain the problem very well. I drained the oil and while I'm adding new oil it is very difficult to see it in the glass. I've tried shining light directly at the glass as well as trying a raking light. It is just very difficult to see the oil dripping into the glass.

No oil visible in compressor sight glass

Well friend, if you have a sight glass for oil, and nothing is showing, best add some right away, and before you use the compressor again.
