HI Moose,
Surprised to hear that there was sludge in the oil when you drained it; I
have not experienced that when changing my oil.
I also thank you for posting this message as it reminded me that I have not
changed the oil in my compressor for a long time and need to look for oil.
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=
:
- Heat absorption: Air compressor oil absorbs the heat produced from
compressed air, thereby keeping the compressor at a cooler temperature.
- Oxidation resistance: Air compressor oil contains additives that delay
the oxidation process and acid formation.
- Longer life span: The additives in air compressor oil also increase
the lubricant=E2=80=99s lifetime, protect machine components when on sta=
ndby and
make the lubricant compatible with a wide variety of conditions.
- Viscosity in cold temperatures: Although some oils fail to do their
job once the temperature drops, air compressor oil maintains its viscosi=
ty
even when it=E2=80=99s cold.
- Demulsification: Air compressor oil also contains additives designed
to improve water separation, which will protect the compressor from wate=
r
and oil emulsions. This makes it easier for the oleophilic bags to captu=
re
the oil later on.
- Anti-foaming abilities: When big air bubbles rise to the oil=E2=80=99s
surface, foam is produced. This increases oxidation because it exposes m=
ore
of the oil=E2=80=99s surface to oxygen. Without anti-foaming additives, =
the oil
separators would be saturated by the foam and the air compressor=E2=80=
=99s life
span would decrease. This is because saturated oil separators create a
pressure drop, which leads to more energy consumption.
Another article I read recommends these three:
1. Dewalt Synthetic Air Compressor Oil
<https://www.tooltally.com/best-oil-for-air-compressor/#1_Dewalt_Synthetic_=
Air_Compressor_Oil>
2. Royal Purple 01513 Synthetic Air Compressor Oil
<https://www.tooltally.com/best-oil-for-air-compressor/#2_Royal_Purple_0151=
3_Synthetic_Air_Compressor_Oil>
3. Campbell Hausfeld MP12 Standard Compressor Lubricant
<https://www.tooltally.com/best-oil-for-air-compressor/#3_Campbell_Hausfeld=
_MP12_Standard_Compressor_Lubricant>
The Dewalt is 20wt and better for start-ups in colder climates.
Royal Purple is 30wt and better for warmer climates. The author said for
hard working compressors, this is his first choice. The CH is his
recommendation for older pumps with more blow-by.
It also says change the oil every 800 hours, or minimally once a year.
Unless I am in a major project, I probably do not get 800 hours of runtime
a year, but an annual change will be on the calendar from now on.
Thank you again, Moose for your post; best post of the day for me. I will
be changing my oil this week, will be using Royal Purple, and will put a
recurring reminder on my Outlook calendar to change it yearly, at least.
Best,
doug
