Air compressors again

[dave.williams@chaos.lrk.ar.us (Dave Williams)]

-> Anyone take special precautions when using a compressor
-> in "cold" temps (ie, below freezing, how about below 0 deg F,
-> or below -10 or -20)?

 Campbell Hausfeld recommends their own special oil, which is
unobtainable locally, or Mobil 1 synthetic, which is what I use.  Mobil
1 will pour fine at -20.
