I slightly overfilled my Z a few years ago and it went wonky. very high, uneven ide. All kinds of air bubbles in the oil.
Drained it completely (a few weeks after the last change) And refilled. No problems after that.

I had a similar experience at 16 with my first vehicle, an '84 Tempo. I was checking oil with the dipstick. Nothing was showing up, so added a quart. Drove, checked, nothing. Add a quart. Repeat until I registered it on the dipstick.
about 80% of the way through my highway trip, started getting really bad engine performance. Bucking, stalling.
Made it to my destination. Left the vehicle for a while and came back a bit later and the dipstick was off the charts. Couldn't start it. Ended up selling it dead, in place for $50 to a maintenance guy (who was a friend) at the location. When I eventually heard back from him, I seem to remember it was something like 7.5 quarts of oil in that poor little 4 banger.
That was the experience that taught me that there is actually a procedure that needs to be followed when checking oil in a vehicle. It's not just a dipstick in a honey jar.
