G'day all,
I've been debating asking this for a while as it's more a whimsical question than anything important.
I have a nice little 2.5HP slow running belt driven comp with a cast iron pump. It has an hour meter, and it sees 15-30 hours a year at *most*. It lives inside, does not experience extremes of temperature and generally lives a very easy and spoiled life.
The first few years I had it I was using generic air compressor mineral oil from the local car place. I found some pretty unpleasant emulsions in the tank and yellow sludge in my below-ground air lines. A couple of years ago I switched to Amsoil ISO100 synthetic compressor oil. Horrid emulsions and sludge gone and I'm a happy camper. Water separator has less oil in it also.
Now, the question. How often do I change it? It has about 2 and a half years and 35 odd hours on it now. Still looks clean in the sight glass and minimal foam while running.
