In terms of optimistic Honda OLMs, I think the VCM V-6s are a great example. I feel positive that if the OLM limited those engines to 5k miles (or thereabouts) on an oil change, instead of the 9-10k miles they commonly allowed, you wouldn't have seen the prolific sludge issue.
The problem with OLMs is you don't know if they're wrong until...well...you know that they're wrong, if you get what I'm saying. GM decided after the fact that some of its OLMs weren't calibrated appropriately, and reduced the OCI by half in some cases. That was after a goodly number of engines were down for timing chain issues. Were these ultimately the fault of the OCI? Who knows. That's what GM pinned the issue on...
