In respond to the OP (instead of the random diesel hijacking that seems to be occurring):
If it's clean motor oil than it's "merely" toxic. Probably not a lot more so than a lot of other smokes. Oil smoke probably has a lot more carbon monoxide than some kinds of smoke.
If it's used motor oil, it's more toxic and it is carcinogenic. Motor oil in a car engine picks up a lot of crap, including any/all of the following metals: steel, iron, lead, copper, aluminum. It contains gasoline byproducts as well as fancy new compounds produced by the combination of heat and combustion gases.
