Here I am again asking for lubrication advice.

Getting ready to change the oil in my Southbend 7" shaper. The manual says to use Medium weight non detergent oil. Would 30 weights be considered Medium weight or should I use 20 wt. Bottom line is it must be non-detergent. So I am thinking about non detergent compressor oil.

Medium would probably be about 30

ISO 68 is common machine oil. Easy to find too.

ISO 68 circulating oil is your friend.

Thanks John. The manual uses a reference of 200 Saybolt so it sounds like they mean 20 wt. I will look for ISO 68. Seems that I may have just bought a quart for my Clausing apron.
