Onan Generator in 996 Arctic Fox...how to?

Wow, lots of variations of advice here. My manual agrees with the oil check in that you do NOT screw in the dipstick to check the level. As far as quantity, my manual states for an oil change, drain while warm and refill with 0.6L/0.63 qt./ 20 oz of oil. Mine doesn't call for a filter so run, drain and refill, then you're good to go for another 100 hrs. In my book, oil is cheap so I change mine annually, regardless of how many hours which after 2 years, we've only got 15 hours on our 2500LP Onan. Oh, and don't drop the whole unit to change the oil, not necessary at all. Also to the OP, the AF996 was introduced in the Fall of 2012 as a 2013 model year, you sure you have a 2010 AF996? Possibly a 990? Shouldn't make a difference with the Genset, but might if you were to ask a question about some other part.
