Went to buy some oil for my compressor and tried a few stores. No one has them, so at the last place I went to the salesman tried to sell me DIESEL engine oil. He said its the same thing,

Is he right?

After the oil is changed the first time,you should probably change it every couple months if you use it pretty heavy,if just on occasional use change once a summer,just to keep fresh oil in it.Just remember it doesn't have a pressure lubed system so as long as you use like a pennzoil 5-30 or an equivalent non-detergent oil,you should have no trouble with humidity . The humidity or temp. changes don't seem to effect them much ,so as long as its not -20 or -30 below you should be fine.Enjoy your compressor!!

I can't say for Canada but stateside, I buy my compressor oil off the shelf at WalMart. Automative department, compressor section.
My compressor does have a pressure lubed system so I'll stick with the recommended stuff especially since it is easy to find around here.

The oil I used for all my compressor services was Castrol non-detergent 30wt. It doesn't have to be Castrol, any decent non-detergant oil will do. The big thing is to us a non-detergant oil.

Agreed

Matter of fact, I bought a Canadian made compressor. The docs say compressor oil or 30wt.

[sbchevfreak]

Really? What breed? And how do you like it? I'm looking for a new one, to power my repair garage, can't seem to make up my mind....

Eagle Model C5160V1
18.5 CFM @ 100 psi
220 volt - Upright tank with 3 cylinders
Paid $599

How do I like it? No complaints. I can't run it out of air. Never had a problem with it. Been using it for about 5-6 years.

During another forum discussion, some guy called me full of hot air. Said he couldn't find one for less than $1100. Whatever I said. I have a receipt for $599 and it wasn't a sale item.

If you're interested in it and can't find a good price, drop me some email. I check on their current prices. I know the store will do drop shipments.

Yah, use only non-detergent oil. I've been using detergent 30 Pennzoil in my 5 horse industrial 2 stage compressor for 21 years and I'm sure the detergent oil is just killing it.

Just going with what I have done, and what I've been told by compressor manufacturers and dealers. They said non detergent oil was important, who am I to argue?


If the detergent oil is okay, maybe I'll give it a try next service.. It's cheaper (at least here) that the non.

Isn't sarcasm great? My problem is that the compressor unit is an old refridgeration unit from, ummm, way back. Should I go with 30 wt, or go heavier? Since my garage isn't heated, should I use 10w30 or just stick with 30wt. Also, my air compressor is a hodgepodge of a Speedaire tank, ancient Westinghouse motor (spins at 1700 rpm or something slow like that, but it's got balls), and the aforementioned refrigeration compressor.

I got it from a friend of the family that moved from Michigan to Georgia. He uses a little chinese pancake air compressor. Did I get the good end of the deal or what?

An old refrigeration compressor! Well, clearly, that calls for refrigeration oil. To get it right, you'll need to know what kind of refrigerant it used to pump. Your local HVAC distributor can fix you right up at about $50 a gallon.

side note: the previous owner of my compressor said he burned up the original motor when he tried to run it when it was cold - below freezing.
Based on just that, I'd go with the multi-vis.

the arabs are raping us! Does anyone else have an opinion what kind of oil I should use in an ancient refrigeration compressor (it came out of a store somewhere) used as an air compressor pump? I really don't feel like $50 a gallon for oil.

Also, what is different between refridgeration oil and non-detergent motor oil? I am thinking of 20w-30, of course non-detergent.

i use a cheap brand compressor oil, belive it's just 30 wt, i've used it when the water in the bottom of the tank froze, so it's not that big of a concern i don't think

HEY, Chevelle, The smiley face was supposed to be a clue. That old pump will probably run with just about anything you pour in it. I'd guess 30wt non-detergent would be an excellent choice.

There are a number of different refrigeration oils and they are often that expensive. You almost have to be a chemist to get everything right in refrigeration systems. Us auto guys usually think about 2 different Freons, R12 and R-134a. There are actually about 20 for different kinds of systems.
