Air Compressor Oil

I was doing some maintenence on my air compressor today and need to know what the fuck I'm doing.
Air Compressor is a Stationary type, Vertical tank, 80 gallon,7 H.P. 2 stage. The motor is electric with a belt,220 volt. Pump is a V-twin,kinda looks like an old Harley,lol.
I bought this from Home Depot about 12 yrs ago and it says on the side it has a 3 yr tank warranty. I've NEVER CHANGED THE OIL.
I drained the oil outta the crankcase of the pump and put in air compressor oil. It was from Campbell Hausfield and the oil is clear.
I remember buying this shit for my air tools.But it says air compressor oil. Should I use this shit or just put some 30 wt. motor oil in it? I dont know what the fuck I'm doing and my book that came with it, the english part is gone and I dont speak french or German very good. Halp!! Mikey

 

Use the air compressor oil.....................It's non detergent, ( which is prone to screwing up some paint job action, if it IS a detergent oil, or "motor oil")...........

 

Does it say anything on the label about being "synthetic" oil? This could explain the clear and odd lack of color. Lack of detergents and additives for internal combustion engines could also explain the lack of color.

 

I use Mobil Air Compressor oil from Grainger Supply.
It is what the company recommended.
Better safe than sorry!

 

ive used10/40 castrol gtx in my matco compressor for 20 years. it still builds pressure just fine. try to change it at least once every 2 years. keep it drained. oil comes out looking just like the oil i take out. oils still cheap and easy to change. clean new oil is better than old nasty stuff

 

My understanding is the clear stuff is very highly refined and what you should use. It's like a sewing machine oil. And no detergents or contaminants.

 

30w synthectic is very ok, air compressor oil is better and it takes hard running under tough conditions to notice the diff, we use air compressor oil and change it every 6 months. if you drain a lot of water out of the tank then oil needs to be changed more often. this depends on your humidty. we get alot more water in the winter time.

 

I have always used Mobile 1 in Mine and try to drain the tank once a mon.

I use Mobil 1 30 wt in mine for last 10 years since new. I change it once a year.

 

30w non-detergent.

 

if use use your comp to paint . i would not put synthectic oil in it ,

unless you like fisheyes..

 

Watching this thread with interest. Need to change my compressor oil too!

 

I maintain 3 different air compressors at work.

All 3 require different oil.

All 3 require different oil.

All 3 require different oil.

RTFM- read the f'n manual. If you lost it, look online.

 

What he said!

 

A guy I used to know who worked on compressors said to use ATF,,, thats right Automatic trans oil,,,so I put it in my Dayton 10hp 4 cylinder 2 stage comp,,,I have been running it for 2 years no problems,,plus it starts up in winter with no problems either,,,,do an awfull lot of sand blasting so it is used all the time....

You'll need the model number.
