I love the new compressor. It had oil which I had Tractor Supply drain out before we laid it on its side for transport. I put IR synthetic in and ran it for the break in period of 30 minutes with no load, then it cycled a few times during the day. At that point the oil was dark. I changed it out (put IR back in) and it is now staying clean.
Bird, you suggestion to put the elbow and valve on the bottom of the tank was brilliant, and is really coming in handy. I have found that it does get water in it during the week when I'm not using even though I emptied it out at the end of the last use. I don't always get a chance to go out and release it every day - the switch is off and the shut off valve is off, although it does have air in it.
