What't the lowest viscosity oil anyone has come across here? It

looks like
some of the "spindle" oils get pretty thin. Are they used in a

special way?
How low are the clearances those bearings run at?



Look at Lilly White sewing machine oil.

What's so special about sewing machines? I've never torn one part,

but know
some have an oil filled sump. Not sure about what the moving parts or
stresses are on those things.


They are fast and use a very low vis oil. As low as ISO22 (on the low
end of the SAE10 range) Due to stain potential they prefer very clear
oil. Other than that. No clue.

Velocite #10 is an ISO22 also, and there are lighter grades of Velocite
spindle oil.


The non-staining properties make sense. For the hell of it, I ordered
some velocite #3. I can't find it in less than 5gal pails in the US, so
the order went to a lubricant repackager in the UK.

The stuff is weird. It's thin and pours like a solvent- not quite as thin
as acetone, but thin. It not suprisingly very oily, and creeps quite a a
bit, bit not as bad as liquid silicones. Color of this batch is very pale
yellow/green. The odor is faint but strange as well.




Maybe it would make a fair penetrating oil.
