I put too much oil in my car (chrome dipstick, couldn't read the marks) and started it for about 30 seconds. I have drained out the extra quart (Jim Beam helped me with the oil change), but am concerned that I may have aerated the oil. Do I need to change it or just let it sit for a day or so?

 

Air is less dense than oil, it'll move to the top in about....10 seconds. Besides, it gets plenty of air when the engine is running anyway, what with the crank spinning around like mad.

 

Jim Beam is a helluva friend but not much of a mechanic.

 

Amen brother!
