another project. I wonder if I can use it for spindle and way lubrication. It
should be thin enough, as it seems thinner even than 3-in-1. I checked oil
lubrication charts for old lathes where SAE 30 oil is recommended. I have
some Shell SAE 40 but it is quite thick and the carriage and slides got a
lot heavier to move.
I have read that this type of oil is higroscopic. Also I wonder if its
more toxic than engine or gear oils.
