If you have a Jack and some stands I would personally drain some of the oil. Depending on what car you drive it could potentially be an issue. Again it really depends how big your engine is. I'm assuming you did your own oil change. You could always take it into a shop and ask them to drain some.
Ok word, itโs a 2.6 L 4 cylinder in a 2006 Honda crv. It burns or leaks oil so Iโm just hoping itโll be something that fixes itself. Wanting to record some music so I just need the car to idle a bit tn to keep the battery charged, Iโll give it a better look/drain some tomorrow if need me
So essentially your capacity in your pan is around 5L of oil. An extra 20mm in the pan is about 2L overfill. In your case that's really bad. What happens when you overfill oil is that it gets aerated like a fish tank and tiny bubbles cause it to almost stop working. It needs drained very badly. It's an easy fix either way just a simple mistake everyone makes.
