I think mine are Golden Rod. They are what our mill bought for our machines . I have seen them at KBC and other places.
In this case II used 30wt way oil,it's what I had on hand, but older lathes suggest 30wt oil for almost everything. You can still get non detergent 30wt . I often use the much more modern 140/80 wt syn gear oil, like what you use in the diff of your truck. In my web search I found a list of oil viscosity for common grades.There were a lot of surprises. So when guys tell you to use what was recommended, do your own research.
