compressor oil

[cedgo]

Hello!
Have an old Chicago Pneumatic Machinery Company air compressor.
Need advise on a proper compressor oil.
Thanks!

Most any Compressor Lubricating Oil sold will be fine!
I bought my last 2 quarts at Fleet/Farm because I was there.

20 or 30 weight non-detergent will outlive you.

I found that the synthetic oil was a necessity in my compressor. The regulator oil work fine in the summer but at 55° or so the compressor could not always start and would trip the overload or the breaker.

Imo the synthetic is a good investment if you care about its longevity.

Some compressor mfg that I can think of upgrade the warranty if you use synth-oil over the dino equivalents, bought at the time of initial purchase. (IR, Quincy, IIRC).

I wouldn't hesitate to use All Season Select or Quin-Cip in any piston-based air compressor.

so this is a blend of synthetic and traditional petro oil.

i picked up my Non-Detergent oil from local O'Reillys, they stock the ND-30 & ND-40.

If your compressor is outside, or your garage isn't heated, a multi weight oil might be a good idea. I am thinking that since they have found that some huge % of auto engine wear occurs in the first few minutes after start, a compressor can't be much different. Also thinking that a home compressor runs infrequently, so a much higher percentage of it's total hours of run time is cold starts than one at an auto shop feeding a lot of techs.

Mobil 1 has been in my 80 gallon Husky for 15 years, it was the recommendation in the manual when purchased

Thank you all for the responses.
Run Mobile 1 in all my gas engines.
What weight would you guys recommend?
Compressor is in an unheated garage.
Temperature today is 11 degrees.
Tag on tank says made in 1947!
Air is always "made".
Have three 80 gallon tanks.

I use Amsoil synthetic compressor oil. In winter the compressor will run with this oil but was very sluggish to start when I used traditional oil. I am in the Chicago area so it gets cold in winter and my compressor is outside.

You are overthinking this...any synthetic compressor oil will work.
Not much variance in viscosity when you read the labels.
