Wouldn't consider them that expensive...believe one's $3 and one's $4...both available at Sears.

I just got a compressor and was wondering about this too. The manual for the impact wrench says the oil needs to have Moly in it.
air tool oil is generally a 30wt non-detergent oil with some other additives. none of the "air tool" oils i have seen are very expensive, considering you only use a drip every so often (daily if used daily). if you paid $10 for a pint it would last you a lifetime. i repair air tools at work that the users don't lube very often but are used near constantly and they still have a very long life.
Where it is just "mist" lubed, an ISO 32 compressor oil is often used. When It gets to the other extreme such as jackhammers and other percusion tools, normally a tacky oil such for Rock Drills is called for such as Chevron's Rock Drill Oil Vistac. A low toxic or non-toxic no ash additive package and a tackiness additive are used to keep it in place. Available in ISO 32, 46, 150, 320 viscosities in Chevron and I have it in ISO 100 in another brand.
But you will be hard put to find these in less than 55 gal drums

We normally use Marvel mystery oil for our air tools where I work. My company bought several 90º die grinders from a Swiss company and after a few weeks we started having problems with them. It seems that they use a phenolic seal inside of the vane and the Marvel mystery oil caused the phenolic to swell and seize the rotary vane.
After having the grinders repaired under warranty we started buying actual air tool oil from the same company that made the grinders and they're performing flawlessly now.
So I guess it actually does matter what oil is used.

interesting thread. today i was cutting out the skirts on a piston for less drag and i was out of my normal air tool oil. i dribbled in a little bit of bar and chain oil for my chainsaw and noticed my die grinder slowed wayyyy down. the sound also changed at it got louder.
so, i was thinking maybe a 0w20 oil or some other thin viscosity would increase the speed of the die grinder. and perhaps a thin oil would let my impact wrench deliver more torque?
i guess i shall play around with this in the shop and report results somtime to you guys. i dont know is a ow20, or even bar and chain oil is harmfull for that matter. my tools arnt expensive swiss units or anything like that. i figure as long as i oil them before each use they will last longer than 90% of the other tools out there that dont get any oil.

i've played around with different lubes in air tools. thicker will make them run slow for sure. i used some grease to assemble one and it would bearly turn over until i blew alot of oil though it. i have some silicone/graphite spray that makes them really fast
, but not for long.

The Amsoil PCH and the Redline Air Tool Oil are two good products for this application, and both are sponsors.
Marvel mystery oil is the oil to use. I got 23 years in machine shops. Every one of them used Marvel mystery oil for air tools.
The secret is oil them real often or have a in line oil feed lube system. I got one burr gun that is 14 years old with much use and is just now starting to go bad. Air tools very a lot in quality any more. If they need any better oil than Marvel mystery oil than it is a poor air tool to begin with after seeing air tools go 1000s of hours on this stuff.
