Onan Marquis 5500 Oil Question

luvmygolden Member Winnebago Owners Club Join Date: Mar 2011 Posts: 34	Can anyone tell me if it's acceptable to use Mobil 1 Synthetic 10W-30 when I replace the oil in my Onan Marquis Gold 5500 Gen set? Can't see where it would be a problem but figured I'd lean on the collective experience of this wise group to make sure. __________________
