Honestly,on a shop run compressor that is in a temp regulated building that's not really a big deal as long as the pumped air filtration is adequate.
If the pump oil is dirty black there might be a cause for concern though.
Compressor oil has no viscosity index improvers so shear isn't really an issue and considering the duty cycle,in and off and not consistently pumping means the oil never really gets super hot which can lead to ring coking.
So the oil has been in the pump 30 years and no problems yet here we get guys all worried about 6 month oil change intervals.
Funny.
I use amsoil because of our duty cycle. The air compressors run steady,not on and off once the tanks achieve pressure,so they are always pumping air since the gas engine is always running. The valve pops once the tanks have been pressurized which then just pumps the air off into the atmosphere.
I've got compressors with more than 10000 hours on them,original Honda 160gx engines and v-twin or triple cylinder pumps and they've never been opened,so my yearly oil changes seem to be doing the trick.
The compressors run in -35 like this morning and 35c in the summertime and the amsoil takes the extremes like a champ.
If your pump isn't exposed to wild ambient temp fluctuations or serious duty then and non detergent sae 30 grade should be fine,and change the oil when it starts turning black.
I put a filter on the crankcase breathers on all my compressors so when it sucks air in its filtered which keeps the oil clean much longer than without.
I make my living with air so my equipment has to work everyday and in this case,due to the extremes,amsoil is king.
Even at -35 the oil pours quite quickly.


May I ask what MFG pumps are you running.


I am sorry for answering so late. I just saw the question.
They are all twin tank wheelbarrow types. All have the Honda 5.5hp 160cc engine. The 2 oldest are made in japan,the rest are Korea I believe and Thailand iirc.
I've got 4 eagle 12 cfm v-twins and an 18cfm triple. 6 roll air inline twins and 5 hitachi inline twins.
As far as the real manufacturers of the pumps I can't really say but those are the brands that are stamped on the tanks.

Its a very light oil when you first put it in but after the 30min break-in period it was rather dark and now with about a weeks worth of running its even darker... should I be concerned? Should I change it? Do compressors need the break in contaminants removed?



Yes. Treat it as any other machine as far as break in is concerned.
I really like the a soil compressor oil. Top quality stuff. And our nail supplier gives it to me for free now.

So Clevy, you think I should dump this first oil change now that its broke in and put fresh in, even though the manuf suggests 6mo OCI's?

I always drain the break in oil rather soon. A compressor pump will have extra wear metals during break in, just like an engine.
I break in for 30 minutes and the run for an additional 30 minutes, then dump it

Be careful about which oil was in that compressor previously. Ingersoll Rand uses some PAG based fluids in their compressors. These will not mix with typical hydrocarbon based lubricants.

IR is nice enough to list their base stock composition on their website: http://www.ingersollrandproducts.com/am-...ries/lubricants

You can mix hydrocarbons with Diester and PAO synthetics, but DO NOT mix them with the PAG based fluids.

If you want to be double sure, mix the new and old fluid in a cup and stir it up for a bit. The incompatibility should be pretty blatantly obvious.
