Can you drive a car with overfilled oil?
I would not start an engine that has the oil overfilled by a gallon. You can cause permanent engine damage by significantly overfilling the engine with oil.

Will excess oil burn off?
The problem is, if your engine is running correctly, it won’t burn it off. While engines will use a little bit of oil, most of that oil is replaced by unburnt hydrocarbons introduced through blowby. Due to this, oil levels most often stay right about where they should be throughout the life expectancy of oil.
How do you fix overfilled oil?
Use your socket wrench to start loosening the oil plug. You want the overfill oil to start trickling out slowly. Let it drip until you think you have drained enough oil, then tighten it back up. If you loosen the oil plug too far too fast, you run the risk of actually taking it out.
What happens if too much fuel and not enough air reaches the engine?
