I don't have a clean air compressor. Plus I wouldn't want regular compressor oil mixing with the new refrigerant oil. Not to mention the crud it would deposit in my new receiver/dryer.
Also, if you don't get the air out you will develop a new understanding of the term diesel. Air + oil (refrigerant oil will do) + pressure = diesel combusion
Neat idea, but I'll just stick with inert gases.
