I know a lot of people here use long OCIs. I ran across this video looking for something else and found it very interesting overall. But it's pretty long so the embedded video starts when the mechanic explains how extended OCIs damaged the cylinder walls and how it happened. The crazy thing is that the owner apparently followed Toyota's own recommendation for 10K intervals and ended up needing a new engine at 160K.
He also explains how you can send your oil for analysis and think everything's great with the extended OCI but it won't indicate what's happening to the pistons.
