No! You need to use air compressor oil. Not motor oil, not air tool oil, but compressor oil.

No. Motor oil and lubricants for compressors are different. Different viscosity and additives. It might work or burn it.... best thing to do is to use what the constructor has prescribed.

Check specs in manual or manufacturer's site. Or leave be. Or get pro maint.

If Compressor is old it won't matter. If it's new you would want to stick with the Recomended Oil. Any Oil is better that Real Dirty Oil. Change It! It won't hurt it! It could run on almost any oil. Compressors are not that picky. Oil Should be Changed a lot in Dusty conditions. Be Careful some people are giving you answers for A/C Compressors.

We use motor oil on our compressor at work. It takes 7 quarts. I know I had to change it the other day. We change it every few months.

My compressor manufacturer specified 20W 50W motor oil. I run synthetic. Motor oil will be fine in yours, thats all I have ever used in 40 years.
