Is it OK to slightly overfill engine oil?
If you overfill engine oil, it can lead to thousands of dollars in repairs . If an excess of oil floods into your vehicle’s crankshaft, the rotation speed of the crankshaft begins to aerate the oil.

How much overfill oil is OK?
Between the add and full line on the dipstick is usually about 0.5 to 1 liter. So if you need to add more oil, do so incrementally – about an eighth to a quarter liter at a time – to avoid overfilling. It should be noted that a slight overfill probably won’t cause any problems.

Same principle here, except it will happen inside your very expensive engine.
