Little Machine Shop has put together an excellent book on the minimill,
meaning the X2, but I would think their recommendations would be appropriate
for the X3 too. Since it's available for free download from their site I
don't think they'll mind if I post an excerpt here:
"We recommend the use of two lubricants on your mill. Where oil is required,
we recommend Mobil 1 synthetic motor oil. Mobil 1 far exceeds the
lubrication needs of the mini mill, and maintains a good surface film
between applications. Any of the available viscosities work fine. Where
grease is required, we recommend Lubriplate 630-AA lithium (white) grease.
Lithium grease is a plastic-friendly grease that is widely available and
easy to use. "
Here's a link to the book:
