I have changed the oil and filter on my Onan 5500 gas gen. set for the first time..The service manual calls for two quarts of oil when changing the filter. I got a good drain (warm). On oil refill I can/could not get the system to hold more than a quart and half of oil...I even let it run for awhile after the change and the level did not change.
Any ideas on why I can't get the recommended oil capacity level?
