[TheForge] Air compressor question

[David E. Smucker]

I recommend straight 30 weight non-detergent motor oil.  The non-detergent 
is important and becoming increasingly hard to find.  The reason for the 
non-detergent as I understand it is that the detergent oils pick up water 
from the air and retain it in the oil.  I tried a detergent oil in mine and 
got a milk colored oil on the sight glass.  Didn't like the looks of that in 
my compressor so took Dan Tull advice and went to 30 weight non-detergent. 
Your farm supply place should have that.
