I have a concern with my 2004 DVX I bought USED. When I first brought it home I checked the oil and it was dirty and the tank was almost full (I MEAN FULL)! I drained all oil and filled between the cross hatched marks. Drove it for a week or so on and off. Noticed my rad resevoir down about a half inch. I guess thats normal? I checked my oil today and its at the top of the cross hatch after my short ride. Cant tell if there is a tinge of green in my oil. Is it possible for the rad to leak into the oil tank? I HOPE NOT!!!!!!
