Narrative:

When I arrived on the aircraft; it smelled as if something had occurred in the air; it was faint smell of oil; nothing really noticeable; but the plane did not smell the same as I am used to. The air felt a bit heavier. I did mention this to the captain; but he said he did not smell anything. When we he released the brakes; a status message appeared that said; APU oil qty low. He set the brakes and we called maintenance. When the mechanic arrived; he too said that the air had a faint smell to it; but in the course of everything being checked on the plane; the smell dissipated. The APU was deferred and before we departed again; one of the flight attendants said that she smelled something in the back of the plane by the galley. The captain sent me back to smell along with the mechanic. We smelt nothing; I even stood under the ceiling eyeball bent in the rear galley and to the side to see if the air had any smell to it; which it did not; at which point I said to her 'it's your call; if you smell anything; now or at any time; let us know.' she said she didn't smell anything anymore and would let us know if she did. The flight departed uneventfully and I wore my O2 mask a few different times to see if I noticed any change or a smell; which I did not. The flight attendants never reported any more odd smells or odors to us and all appeared to be normal in smell and function of the aircraft with the exception of no APU.
