My only experience is with a propane powered suitcase generator. As Thomas suggests the oil and spark plugs stay clean giving me at least a sense of emission friendliness. Surprised therefore that a CO alarm I have for the stove inside was triggered even though it was 30 feet away from the generator which was running outside the boat with doors to inside fully closed!
