I don't think it is anything to worry about. Old mechanics will tell you: Blue/grey smoke= oil burning, black smoke= rich mixture (gasoline burning), white smoke=
condensation in the tailpipe (water). You smelled oil because all exhaust smells like oil.
If it only does it on morning startup (especially after a cold/humid night), and the smoke is white, it is tailpipe condensation.
