I don't think it anything happens but it depends on if it is a different type of oil going on petrol then it will probably.
Not much. It'll smell a bit as th engine heats up untin the excess has burned off..
it burns
It has already happened.
It will spill out
it mostly happens in the ocean
very slow like malases
the last oil spill was the oil spill in the Gulf Of Mexico
It would cause pollution to sea and the oil would poison fish and sea gulls.
Cat litter is good to soak up the spill after it first happens. It will usually get all of it up.
