How much oil for HF 21 gal compressor?

[Indy_500]

Guy at store told me it'd take around 24 oz. they had 2-16 oz bottles so i grabbed 2 of them. I have about 8 oz. in and it's reading that it's over the full line. I ran in for about 10 seconds and doesn't seem to be going down.

If you don't have the original manual I would try to find it online or at the store.

I have the red one, #94667. I bought 32 ozs, #95048, and if memory serves, I used all of it.

If it's that one that's on sale now for $169 then 5.6oz sounds right, mine didn't take much at all.

I have the new one that's on sale for $169. Figured I'll just get it, and when it's time to upgrade to a 60 gallon (5 or so years) I can because I didnt spend $400 on a stupid 20 gallon compressor. My oil level is inside the red circle on the glass reader, but it's not in the center so i should probably drain just a tad more. I broke it in last night and it ran good. Filter worked good, no air leaks at all. Don't understand how the in-line oiler is supposed to work?? But I had it filled with air tool oil. I didn't really use any air tools last night other than get my impact and die grinder going again since they've been sitting for so long. Finally got all the stupid warning stickers off! The dang thing looks like a manual itself.
