Reminds me of my old job when we went to pick up our work cars from Firestone, one was a 2015 Ford Escape. It was so overfilled smoke would just billow out of the tailpipe when accelerating, and you could feel the engine just struggling to even rev up. It was 3-4 quarts overfilled when I pulled over to look at the dipstick, turned around to have them "fix" it. They tried to play it off being a quart overfilled, but the damage was done. It smoked like hell when leaving, and not too long after they put a new engine in after the piston rings, and seals were trashed.
Its great being able to see what happens inside an overfilled engine however.
