Oil recommendations for Yong Heng compressor

lol, i put royal purple in mine when i got it several months back and havent changed it yet .. just fill it to the marks the instructions tell you to .. oil wont save it, neither will buckets of ice and radiators .. its longevity is directly proportional to how hard you beat on it, i suggest giving it plenty of breaks on your 9 liter tank .. you need a check valve on your fill apparatus to facilitate that ..

Use good lube if you want it to last. I've used Chemlube since mine was new (3+ years now) but other options exist. No rod bearings in these things so I'd recommend a break in oil change after first run and changing the lube regularly thereafter. One theory that might well be correct is that detonation may be as responsible for failures as is heat. Might be seems accurate as no one knows for sure. Quality HPA compressor lube would seem to be much less likely to detonate. In addition, keep it cool if you want it to last. Plenty of information on this going back years, but no one knows for certain where in the heat range failure becomes more likely. Or, follow the other advice from "several months back" and take your chances.

Lots of information on Yong Heng lubricating oils in past threads. Do SEARCH "Yong Heng Oil" in forum "Air Tanks, Compressor, section. I used HUSKY Synthetic Blend Air Compressor Oil ($6.99@16oz.) for first hour break-in oil change. After that went to Full Synthetic HUSKY Air Compressor Oil. ($9.99@16oz.) Compressor takes 10 ounces.

You should change pretty son after break-in

I use shell corena s2 p150. Cheapest high quality high comp compressor oil I could find. Works better than royal purple as I have use both. Royal purple is not for high comp compressors.

I've broken my compressor enough times in the past. I'm good on all that.

Why do you not like royal purple and say its not for high comp compressors? I have seen at least a dozen reviews saying that royal purple is one of the best to use with the yong heng. 
 
I have seen several who have used Royal purple have the rods go through the casings on their Yong Hengs as well so maybe it is not the oil but...

I also use the Husky brand synthetic or synthetic blend, and have for three years, on two different compressors. Fergot to put oil in the thing once. Cranked it up and filled my Impact to 3600psi without any oil in the crankcase. When it bogged down a bit, at the end of the fill, I figured I trashed it. But I put oil in it and it is still werqing several months later. That says loads about an oil to me.

This is not a high compression compressor oil either, as far as I know, but I have not seen signs of any kind ignition problems, like with the Royal purple, in the thing since I have had it nor on my first unit either.

Ignition problems?? Are you saying the oil is detonating in the compressor? Like dieseling in a air gun? I thought that only happened if you got your unit to hot? Or at least that's the way the video I watched made it sound. So picking an oil that wont ignite is probably important then. I have a break barrel I only use for stuff like dieseling, If a compressor oil wont diesel in a air gun does that mean it is probably safer to use in the compressor? 

And the husky brand oil I am guessing you guys just got that at home depot? And I am guessing synthetic oil is less prone to the detonation issues?

Go to forum section, "Air Tanks, Pumps, Compressors, Filters." On July 10, Rangeland started thread, "I Need Oil for a Yong Heng Compressor." A member, acs, offered a clear, concise summary of the ignition and dieseling concerns, you've expressed. He suggests the use of Bauer Synthetic Compressor Oil for high pressure compressors. I recommend reading this thread with special focus on acs's comments, I think you'll find some answers.

P.S. Yes, HUSKY is Home Depot brand, but sold on Ebay, too. Think Bio and I will continue to use.

While flash point is important, a more important characteristic is the published viscosity index number for the fluid. While an arbitrary unitless number, most fluid manufacturers submit their product to independent labs for testing. This number is key to longevity and therefore the lubricity across a wide range of temperatures. I personally recommend Seco lube 500.
