Draining compressor oil

[ollie]

I hated changing the oil in my compressor so I just made this setup which makes it easy.
A right angle brass airline fitting
Short drain hose with fastener at end
Old aluminum water flask with two magnets stuck on it.

Now I can just loosen the drain hose, put it in the flask and go and do something else instead of watching oil splash everywhere

how often do you change the oil? I think in the 30 years I have owned two of those pumps, I've changed the oil maybe twice, and it is due again. The oil is always clean when I drain it, and the level is always full.
