Every ND oil I have seen never had any aw additives. Why not? Why does non detergent= no anti wear additives?
Why doesn't ND oil have aw additives?

I think you can buy prop aircraft oil that does however. I could be wrong though.
Good question. I think some air compressors list ND oils and they have pistons and rings. Maybe I am confused? Ed

Exactly. I was told that ND stuff is for air compressors

So piston type air compressors don't need anti-wear additives? I think they do. Ed
Compressor Oil is designed to provide long service life in most compressor applications. The thermal stability and oxidation resistance of these fluids can help to maintain cleaner compressors, thereby enabling longer running periods between scheduled maintenance and oil changes. The outstanding anti-wear and corrosion protection are designed to enhance equipment life, while reducing maintenance requirements.
This is from the Mobil oil site. Demonstrates anti-wear and corrosion protection. Ed

When I was a mechanic and when they changed the compressor oil, if they ever did, they used whatever motor oil was in the shop. I was at a diesel (class 8 truck) shop for many years and it was Rotella 15w40.
If you need aw, I would use an antiwear hydraulic oil in the appropriate viscosity i.e., AW32, AW46, AW68. Detergents in compressor/hydraulic systems emulsify water condensate and don't allow it to separate readily. Check out Mobil's DTE line.

Our 5 year old ingersoll rand says SAE 30ND on compressor plate
My dads 46 year old Montgomery Ward manual says SAE 30 or 40ND oil as well

Modern compressor oils have a phosphorus Anti-Wear component and anti-oxidants.
ND oils have only one additive "component" and that is a Foam Inhibitor.

Dedicated compressor lubes will have some. Mola made some distinctions somewhere on the board here, and maybe will see this and chime in again.
53' Stude: One of our compressors' manuals says ND 30 on one page and 10w30 Mobil 1 (actually by name!) on the opposite page.

Garak: that's quite a quandary eh?
I have a 2 cycle Graham Paige rototiller from the 40s? 50s? and they recommend 30w ND oil to be added to the gas. The company today is still recommending the same.

Yep, it was a pretty funny thing to read, one page calling for ND 30 and the next page calling for a fairly high detergent, high TBN API/ILSAC multigrade.

So Garak; what did you use?
Here is what really irritates me: local generic brand gas stations stock cheap motor oil, including ND oil. Customers that do not understand oil frequently buy the cheapest ND oil for their cars- they need a quart or two to top off the hoopty. They buy this stuff and add it to their car: I have seen teenagers add it to their Honda Civics, rednecks add it to their F150's, and soccer moms add it to their Lexus. Nobody reads the label where it says "not appropriate for late model cars" or similar verbiage. I guess a quart or two of this stuff is better than nothing, but I just wish the clerk would point out "your better off using the stuff that costs 25 cents more".

I used ordinary compressor lube from Home Depot and then Castrol ND 30.
