Is a centimeter over the oil fill line too much oil?

too much oil can make weird things happen in the engine. crawl under there and loosen up the oil pan bolt enough to let a little oil out. just a quick stream out and tighten back up. that way there are no worries.

I wouldnt worry about it myself. That little bit wont do anything negative to the vehicle. Also some will go into the oil filter, after a few drives it will probably be right at the full mark.

And kudos for changing your own oil!

it somewhat is ulcer only gargle with very heat water and salt this could kill the an infection and continually clean your mouth with heat water and salt it somewhat is greater advantageous than distinctive the oral drugs suited of success

Its fine no worrys drive it , 1 centimeter is only about 1/4 of a qt drive it it will be fine , 30 years exp on cars and big trucks

No big deal, a centimeter of overfill won't do much damage, if you notice a check engine light and/or smoking then is the time to remove some, but most engines aren't that picky or precise.

Best of luck.

yes you should drain some out , especially if it is more than a quart.
