Compressor oil

[Hukshawn]

Its time I do an oil change on my compressor pump.
Any thoughts on oils? Or just go to the hardware store and buy "compressor oil"?
There are no markings on the pump. Its a no name chinese 2hp, I run it about 800 rpm.

30 Wt Non Detergent Oil is sufficient

30 Wt Non Detergent Oil is sufficient

That is what my Husky 5HP manual recommends.

K. Thanks guys.

+1on 30wt SAE or ISO 68, Machine oil.

Iso 68? The hydraulic oil I'm using for spindle oil?

 

[Hukshawn]

Actually, that would make sense. It had been suggested that compressor oil could be used as spindle oil.
I'm sure it was you, eddy, who suggested I get iso 68 in my mill rebuild thread.

 

[Hukshawn]

Nope. I'm a total liar. I have iso 46 and way oil 68

my compressor calls for 5w-30 Mobil 1

How often should it be changed? I’m at least a year in service on my current oil, with quite light use.
