Given the fact that you are replacing all valves and also cleaning the heads, this would be a perfect time to switch to synthetic. I might suggest you also clean out the 2nd stage separator element and take a peek in there as well. Blow out the intercoolers to insure they are clear and free. Lastly I suggest you change the oil twice. Run it for about 3 to 10 hours, then drain hot, then refill and drain on schedule.Another question...
Regarding synthetic versus petroleum based lubricant. I have read that switching from petroleum based to synthetic is "not" a good idea for a compressor that has been run for greater than a hundred hours or so on petroleum based lubricant.
I have no history on the unit and I have no idea what is in the crankcase now (see attached pic). Should I just assume it's petroleum based and stick with that? It will be getting all new valves and a new floating piston. In addition the heads will be cleaned accordingly.
Thoughts???
Excellent, execatly what I was hoping to hear, thanks again for the help / directionGiven the fact that you are replacing all valves and also cleaning the heads, this would be a perfect time to switch to synthetic.

You are in a great opportunity to do this.
Thanks for the offer Argo, and I understand your position or stance on the subject. Yes, I agree it's highly unlikely the P-0 purification housing would fail but having zero history subject to prior utilization in addition to some questionable "maintenance" performed on the safety valve I think it's prudent to go forward with replacement. Regarding the old one, I'd prefer to hang onto it... As stated previously, if you're in need of any parts, reach out to @oldairdude (Porter Stiles). He might still have one on hand.No need at all to change filter system. If you do so I'd like to buy your old filter. Please send me a PM for price, thank you.
