Non detergent oil for air compressors? #3467799

So, as I understand it: Non detergent oil is used in air compressors because the moisture will settle to the bottom of the drain vs. emulsifying. Seems to make sense to me.

Now, here's the confusion. My compressor, a Kobalt 30 gallon compressor, has a sticker on the side that says non-detergent oil. In the product manual, it specs out either Kobalt's own oil, or Mobil 1 synthetic 10w-30.

So... This begs the question: Why would they recommend a passenger car oil while warning of "regular automotive oils" in the user manual? It still doesn't add up with the non-detergent oil labeling on the side.


What's different about Mobil 1 in this application?

Walmart sells non detergent oil by the quart in it's motor oil section. Way cheaper than then little bottles in the air compressor area.

Your compressor was engineered using Mobil 1 engine oil, the world's leading #1 synthetic oil. Tests have shown that more compressors run on Mobil 1 engine oil have their serviceable life extended two to seventy times vs compressors running the next leading synthetic oil. wink

If the compressor allows for the synthetic 10w30, i would run it. I think they run forever on anything as long as it doesn't run dry!

When i bought the Quincy the service guy told me it only needs the most basic oil, the additives found in engine oils are of no benefit to it.
On the other hand he didn't say those additives would harm it either, i cant see how it would either but i deferred to their recommendation.

Accel is the non-detergent oil I commonly see at Walmart.

You can't be serious.

I've got 16 5.5hp Honda powered air compressors. I've NEVER used a detergent oil in them. I use only amsoil compressor oil because of the conditions these pumps operate in.
From 30c to -40c we are working and amsoil stays fluid at those cold temps.
The engines get supertech because I need 5 gallon pails because I've got so many compressors to service.
Use only non-detergent oil in the pump. I've seen guys use regular oil and the stuff foams up once any moisture gets in the oil. Foam isn't a good lubricator.

Detergent oils will foam up when agitated. Foam doesn't lubricate very well, and is why non-detergent oil is recommended.

^^Makes sense. But I still don't understand why they say non-detergent and Mobil 1 in the same breath

I can understand that angle - only an "R&O" add pack is needed/desired because of the basis of operation. The fact that the detergents are the means of emulsifying water in the oil is news to me.

I am on a 25 yr compressor oil change cycle. I changed it this year and last time was in the 1980s (give or take), actually that was when it was new. Its 5HP two stage that does not see a while lot of use.

The issue is I am 61 and thus the next oil change will be when I am 86.

I am not sure what the additive is or what oil has it, but Mercruiser gear oil has an additive to hold water with the gear oil and not let it settle out. I believe it just holds it in suspension. Not being a chemist, I am not sure of the difference between emulsify and suspension. Darn another question my Dad could answer. I miss him.

Sorry for creating a zombie thread.

How does the action of a compressor "agitate" oil and that of an internal combustion engine NOT agitate oil?

I must be misunderstanding something.

Don't motor oils have anti-foaming additives?
