I tend to favour thick steam oil like 680 where i can get it directly into the cylinder, for displacement lubricators i use 460 grade.
For bearings i use 220 grade, i have got some 100 grade which also works well and some super thin oil that came from MSM. As Jan has stated the thin oils are ideal for Jensens where you need to draw it up the exhaust.
