I hate diesel exhaust. New car smell makes me want to puke (and did, on numerous occasions, as a kid) so bad that I have to take breaks and open windows. The absolute worst is burnt heavy fuel like mazut, and other two-stroke engines that burn oil. It smells like cigarettes to me, but worse. On the other hand, gasoline is kind of nice to smell. Go figure, chemicals react weirdly with our sense of smell, I don't think it's wise to rely on it for synthetic compounds (cue bitter almond smell). Edit: And it is commonly accepted that odors are wired to memories, so living on a boat when I was young and having family members that smoke are probably linked to these sensations.
