Hmmm I'm not sure in that case then!! With regards to the other question, if you over fill your car with oil it can cause damage to the internals of your engine. This is because oil is used to lubricate the internals of your engine. Oil cannot be compressed and too much will result in the excess oil "foaming" this will result in the oil not lubricating the internals properly however all this would only be a result of a massive overfill. Also as far as I am aware overfilling wouldn't result in less oil now! And with regards to the smell of oil, it may very well be old oil as it can take a while to completely burn off.
Also its worth noting too much oil in your engine will cause low oil pressure, contrary to popular belief.
Sorry I cant be more help with regards to the original question!
