OK I have searched for days about machinery oil and the question I have I would think it would be simple... However it seems that is not the case. I would love for this to be settled once and for all. I understand the difference between iso and sae ratings. I know about the Mobil oils. So without further ado here is the question/ statement... I own OLD equipment and whenever you see an oil to use they don't mention iso or sae, they simply state #10 oil or #30 oil etc. Now is that an iso rating or sae? Is "#10" oil velocite 6? I can't believe this answer is nowhere to be found. (I may not be searching properly) Please good people answer this question once and for all. When it says #30 oil what rating are they using? We are talking equipment from the 30s to 50s. From atlas lathes to delta scroll saws etc. Please someone end my misery and give me an answer. Thank you all for your great info. If anyone knows it will be on this site. To beat a dead horse, why do the old manuals just say #10, my only thought is that it was common and there were only 5 viscosities back then and it was simple. HA! Thank you again.
