I have a Cooper/ Buckeye brand air driven fixture drill that requires Buckeye #1021775 Hydraulic fluid, Great except that Cooper no longer seems to be in business and list no viscosities for their oils found in old catalogs. The model I have is .4 HP and runs at 22,000 RPM. Not super high speed so I would guess some kind of mineral oil. Coopper listed required oil as Air line Oil but at what Visc? 5 ISO? or is that too thick? I know I don't want to run this thing too long without fluid but I need to out this thing in service. Any help or guidance would be much appreciated.

Dextron II seems to be the default air tool oil.

There is no T in Dexron and this is a vane type air motor, not an automatic transmission. My employers seem to have no trouble finding air tool oil and every tool has a oiler.

No, its not an automatic transmission. Please tell that to all the rotary screw compressors that specify Dexron II.

Got some velocite on the shelf, for your b-port spindle? If so, that's where I'd start as a guess.

The brocchure that I've found mentions that the lubrication does not cause an exposure hazard which would negate using Dexron or Marvel Mystery oil . The same brochure describes exposing a piece of paper to the exhaust and checking to see that the paper is atained after a minute. I won't be using this thing much but I'd like not to have to breathe in petroleum when I do. Guess I'll look for a thin mineral oil.

At that speed, Velocite 6 (ISO 10) (even Velocite 10 (ISO 22)) or equiv. spindle oil?
Both lower in viscosity, and lighter on additives, than ATF.

Put a diaper on the outlet.

Surgical face masks are readily available. They stop VIRUS sized particles according to popular misconception.

Rislone is a ultra refined lubrication oil. I use it in all my air tools (aviation back ground) I have many ;-) Even a recip. saw ;-)

just for the record, dexron II has a kv of around iso 46 (@40°c). no idea why people think atf is very thin.
