I accidentally overfilled before a track day by about 1/3 - 2/3 a quart too much and during my last run I blew a huge smoke bomb, and the CEL flashed (misfires in 3 cylinders). I had overwhelmed the AOS and some oil got sucked back around and into the combustion chamber. I have heard if too much gets in it can mess up the engine due to oil's hydraulic properties not being compatible with the compression of the cylinders. I was freaked out!

When I got back I dropped the oil filter and emptied the filter housing, and installed a new filter (I took apart the old one, it was good, no debris), and installed a new filter and o-ring. That brought my oil down to half way between the top and bottom bars (before it was a couple bars over the top)

Next track day all was good and I drove even faster and harder than before.

Between 1/2 to 2/3 of the way between the low and high bars is where I like to run my oil now.
