Here in Ohio, it gets a lot of water in the tank as well as in the compressor crankcase. I change the oil about every 6-8 weeks in the spring and summer due to milky oil. I drain the tank about once a week during those seasons. Have a separator for my lines and power tools. Have about 250 ft. of hard plastic plumbing running through various small garages and the shop, through attics and some underground. Auto drain would provide some extra piece of mind. Run about 150 PSI at the tank. Compressor is around 40 years old but I rebuilt the pump a year ago.
