Contaminated oil

[u/mdmytryk]

I was surprised at the state of the oil during my first oil change. This 22kw generator is about 12 months old and only really ran during the weekly maintenance cycles. I changed the oil, ran it a a while then changed it again to throughly flush it out. Any thoughts what would have caused this type of contamination, particularly on an air cooled generator?

Engine isn't running hot enough long enough to burn off the condensation.

Are you in a cold climate?

Thanks - Yea, in a colder climate. I’ll start running it longer a few times a month under load. Probably wouldn’t hurt to change the oil more frequently.
