I recently serviced my 5hp compressor and changed the oil. As far as I know it had the original oil in it that was 10+ years old. After researching I settled on the Triax Kompressor MV ISO 100. I drained the old oil that was fairly black but full. My pump has a round "bullseye" sight glass on the side that I removed to clean the dark oil out of it so I could get an accurate reading when I refilled it. Refilled it with the Triax and ran it and let it sit to verify the correct level which is half way in the sight glass level with the red dot in the center. In the past the compressed air didnt have any sorta smell to it, but now it does. I am assuming the synthetic oil or additives to the oil is giving off the smell. Anyone else notice this?
