Yeah, it really isnt soot in the sense of the typical black ring you sometimes see. This is an oily trail... And Ive used zero oil.
Im thinking that the oil is not volatile enough to combust when directly injected. When put in a non-DI engine, it hits a hot valve face and can pick up some extra heat, but in the DI application is just right there and doesnt combust.
Ive seen oil out the exhaust of small 2-stroke engines, why would it be any different here?
