2 Years Without Changing Oil?

I went several years before changing my genset oil because I only put 10 or 12 hrs a year on it. The dipstick was always clean and the level was good. When I did change it there was a lot of white creamy sludge in the bottom that did not show up on the dip stick. So condensation is a real problem especially over the winter, and even though I ran the genset before I drained the oil it did not burn off all that sludge. I don't know what an oil analyses would cost but I am sure it is more than my oil change and filter. I am sure there are a lot of variables as to were you live how long the engine sits between use etc, but I think a yearly oil change or every 12,000 miles is good advice.

That's what I saw too on an Onan that the Lady neglected to have changed for 2 1/2 years. I would pull the dip stick and be clear and nice. After you warmed it up for the oil change it was black and not nice oil. All she said was well... ''I never hardly ever used the generator''. So why do I need to have it changed?

I showed her the oil taken out in a clear pan and the bottom was starting to settle and looking milky. Not pretty.
