Someone in the Yahoo 4x6 bandsaw group said they know for a fact that
automotive type 90 weight gear lube will attack brass and bronze if
used in machine tools. Has anyone heard of such a thing? I was going to
use Mobil 1 EP Hypoid Gear Oil (SAE 140) in my Clausing 8540.

Thanks, Steve

When I was researching oil for my Van Norman the presence of "yellow metal"
in the gear box ruled out a few choices, according to Mobil's tech support.
