Quincy Air Compressor Oil Question.

[roblouvasz]

One of my Quincy compressors has the 325 pressure lubed head with the oil filter. I've used the Quincip 100 ISO 30 oil it since I bought it used a couple of years ago. From what I've been told, the Quincip is nondetergent oil that allows any particulates to not remain suspended in the oil. Would it be better to run a conventional 30w oil in it to keep the particulates suspended and allow the filter to do its job? The Quincip is a bit pricey from Quincy plus their shipping. If I stick with 30w non-detergent, is there anything else out there that is the same or better than Quincip? The other Quincy I have is the QE-5 and is splash lubricated. I know I have to run non-detergent it. Suggestions?

Darn good question, since anything without a filter normally uses non-D so the dirt settles out in the bottom of the sump. But with the pump circulating it thru the filter, the filter should catch the dirt IF it stays in suspension.
Regular motor oil is made for the high temperature environment of an engine, and doesn't have the additives that deal with condensate formation.
I'd have a look at the Amsoil full synthetic compressor oils....still probably cheaper than the Quinsip.

You will probably get a bunch of good advice and opinions on oil.

I recently bought a used Quincy which came with a couple of pairs of OEM oil and I can attest to the fact that it IS pricey.

$520.28 USD a pail.



Invoice attached for you doubters



Please note that I did not purchase this oil. It (and spare parts) were included in the sale
