I own both a yong Heng and the hatsan lighting compressor. I tired hydraulic oil which was recommended for the yong yeng. I also tried mag1 compressor oil that says non detergent on the bottle. And I tired royal purple 100. That all stink of oil when running the compressor. I run it indoor so the smell is much worst than if I run it outside. Is there an oil that doesn't smell when running in the compressor or is that just normal for these oil type compressor to give off this odor.
