Yes, 30W is a probably quite a bit heavy for sewing machines but it seems to help if placed where indicated by the
green arrow only. You can read about in Cari's posts on the thread
She's real fun, my 401... (only a few pages long).
I was trying to do some research this morning about the viscosity of various oils. For our vintage machines the recommended oil is sewing machine oil with a viscosity of 9.6 cSt @ 40°C; 2.61 cSt @ 100°C. I also looked at the sds or msds of some of them. Some have suggested
mineral oil, but that one has a higher viscosity of 34.5-70 cSt @ 40 ºC. I didn't read all but I think some of the Sailrite machines might use some heavier oil.
