My brother in Law has a Master’s in Engineering he was a researcher for Chevron for YEARS. He has tested oil on engines that power huge ships. I’ve always been that guy that changed his oil every 3,000mies and always bought Premium Oil. One day we were talking and I asked what he thought the best oil was for my vehicle. His answer was simple. “FRESH”. That’s the most important thing. And it applies to EVERYTHING. Cheers. Change your oil on a regular basis and your Machines will LAST.
I really don't know anybody who uses "real" air compressor oil. Please don't get me wrong; all those recommendations like "detergents are bad" make sense, no doubt. I have a big commercial air compressor in my shop (10hp "Boge") and it runs about 100-150 hours per month. I own this compressor since the 1990s and I put whatever oil I have on hand in it when I do an oil change once a year. Every 10.000 hours or so I take it apart to service the valves and it hasn't any issues whatsoever. The cylinders look like brand new, it still runs on the first set of rings, no sludge at all, bearings are fine.
All farmers know and understand how farm machinery work and no farmer is going to run out and buy air compressor oil for their air compressor just because someone says so. Air compressors and 4 stroke engine are exactly the same engine design with the exception that an oiled air compressor lacks a power stroke. Nevertheless, if one changes their air compressor once every 10 years with a good synthetic oil they should have zero problems for another 10 years. Synthetic oil was designed by a NASA engineer to work in -50 Celsius and colder temperatures (so viscosity would never be a problem). Since an air compressor does not have a power stroke there should be nothing in an air compressor that would even contaminate the compressor's oil either... An oiled air compressor doesn't generate enough heat to cause the oil to thermally break down as there is no power cycle in an oiled air compressor.....
I do Marine repair for a living and restore muscle cars this is very interesting. I tore down my old school Crafts man compressor to put in a new seal but the seal is NLA I flushed the compressor out and resealed the bottom crank case . Its American made you cannot buy compressors like this anymore. Anyway I went to Orielys checked on compressor oil its 30 wt non detergent, Well hell I went to Napa asked for 30 wt non detergent and its $5.95 a bottle guess what I bought ? So I just changed it with the Napa oil I am waiting on a belt for it trying to find one.
You don't need a $14 bottle of "compressor" snake oil. All of your normal home air compressors use non-detergent SAE-30 motor oil...It will say so in your owner's manual. Same common oil you'd put in your small engine lawnmower, or any small engine.
All sounds good , although its also a checklist of what needs or will happen in a combustion engine. Having had multiple talks w oil companies on additive packages. IR and the like do not explain why the nondeturgent (which is obsolete) is detrimental to operation of said pump . Exception would be clean air pumps. I will prefer a detergent to clean the pump and suspend solids till next oil change. Also the multi weight oils are superior if your pump is not in a climate controled room.
I just use what i put in my truck engine. Does it matter? I doubt it. My compressor works awesome. Always has and always will. I change the iil every year. Most issues come because people never change their compressor oil.

Wow. Explained really well. Thanks for the straight forward information that applies to many different areas of mechanics.

Good insights! Thanks for writing. Best, DFJ
In one ear and out the other.
Thank you for the clarification. God Bless
Glad it was helpful!
Don't listen to a word this man says he may be the dumbest guy I have seen on you tube ever.

Both my vintage Speedaire compressors were manufactured way before synthetics were invented 😂
Well explained...thanks a lot
You are welcome!
You can purchase Royal Purple 30w nondetergent full synthetic oil for $13 a quart
Love it. Thanks for the tip! Best, DFJ

That's some good insights. Thanks for commenting. Best, DFJ
My dad does oil analysis tests mobile oil is very competitive and good oil.
Amsoil is better for most options.
Thanks for this! Best, DFJ

Thanks for sharing - good insight. Good on you for regular oil changes. Best, DFJ
Stupid is as stupid does.
@@karlandersen1984 His compressor works awesome with engine oil. Always has and always will. It's difficult to argue with this kind of airtight logic.
