How much oil does a Kobalt 2 stage 5.0 HP compressor hold?

The oil has not been changed in a long time and has a lot of moisture in it. The sight glass is dirty and I can not tell for sure how much oil is in it.

Hard to answer without knowing the model number and checking the specs.

However, you want to be able to see the sight glass as oil is consumed while the compressor is running and almost all oil lubed air compressors need compressor lubricating oil added from time to time.

Since you are changing the oil anyway, once you have the sump drained, the sight glass should screw out of the sump. Clean the glass, and then refill with clean oil to the middle of the center dot.
