Technical Compressor Oil Question

I’ve got an old DeVilbiss upright compressor in my shop and it calls for 20 weight engine oil. Doing a little research online it seems that the consensus is 10W30 is the closest match performance/specification wise to 20 weight engine oil. Before I add some 10W30 to the case, does this sound right?

Thanks in advance.

Wouldn't you want non detergent as the compressor does not have a filter?

 

You can get straight weight oils at farm stores and Oriellys

 

You can also buy compressor specific oil. NAPA sells it as NAC # 82-6020 although it is advertised as 30wt
I believe Sta-Lube makes a compressor oil too

Yes, non-detergent 20wt is what you are looking for. Older compressors usually wanted 20 or 30wt non-detergent oil depending on ambient temperature. Newer ones usually use a synthetic compressor oil.

 

Non detergent 30 w is all I’ve ever used in older compressors and it has helped my compressors last for a lot longer than they should have. It seems like Castrol is what I always find on the shelf , although I have no preference. I change it when it looses its golden colour.

 

Good question and use 30 wt non detergent oil.

 

I used regular 10w30 for years with no problems. Then I toured the amsoil plant and switched to amsoil compressor oil now the compressor sounds better ( quieter) .

 

I switched to the Amsoil synthetic oil in my compressors ten years ago.........
