<p>The purpose of detergent in automotive oils is to keep particles
suspended so that they can be removed when the oil is pumped
through the filter. If there is no filter, the particles remain
suspended in the oil that is circulated/splashed about; those
particles can abrade surfaces if not removed from the oil.
Non-detergent oils allow the particles to settle to the bottom of
the sump, which happens when the compressor stops or is idle.</p>

<div class="gmail_default" style="">I saw this Quincy article on
compressor oil options, but it does sound like compressor oil
mainly needs to be non-detergent to eliminate carbon build-up
(I never could understand why automotive engine oil would
create carbon in a compressor which I have to believe runs at
a much lower temperature than a compressor, but that is their
statement), but also:</div>

water separation, which will protect the compressor from
water and oil emulsions. This makes it easier for the
oleophilic bags to capture the oil later on.</li>

abilities:</span> When big air bubbles rise to the oil’s
surface, foam is produced. This increases oxidation
because it exposes more of the oil’s surface to oxygen.
Without anti-foaming additives, the oil separators would
be saturated by the foam and the air compressor’s life
span would decrease. This is because saturated oil
separators create a pressure drop, which leads to more
energy consumption.</li>
