A lot of people see diesels as "dirty" because of the soot that comes out of the tail pipe. I've had several conversations about this and i always tell people. the emissions from a gasoline engine is clear and orderless and goes straight into the air. that dirty diesel soot is heavy and falls to the ground, and its black. easy to see and clean up. unlike the what you are breathing from a gasoline engine and don't even know it.
