I think this is one of the reasons Terry doesn't like his comments disclosed on this board. I did ask him if it was okay to post on the board that he instructed me to drain the oil and he said it was okay. But I can definitely see why you have to be careful with recommendations taken out of context.
No disrespect to texasproud - he is just trying to get some answers.

If you really want a serious defacto answer to your question, it's going to cost you a UOA and a Terry Dyson interpretation. If you want my honest advice, I would keep it in unless you are willing to do the above. I think my situation was a little unique and I was willing to pay for the information. Even then, Terry Dyson’s analysis is just his opinion
. He has just forgotten more about oil than I will ever hope to learn so I’d be a fool not to listen to him (especially since I paid him money for that opinion).
In the grand scheme of things, however, I think even with the abuse my factory fill oil saw it wouldn't have made a huge difference in wear to leave it in. I mean, most of us here could probably agree that if you follow the manufacturer’s directions your engine will give you a long service life. Sure, we can do better then everyone else by trying to find that sweet spot using UOA. But for the most part, I believe that your Honda is going to live a long time if you just follow the manufacturer’s directions.
The question is; "how nuts are you?" If you have been bitten by the BITOG as have I, you can rationalize spending $50 on a UOA and Dyson Analysis to lower a few PPMs of copper out of your oil. But if your sanity quotient is higher than mine is, I would not hesitate to leave the factory fill in until the OLM tells you to dump it.
Again, you have to ask yourself why Honda would strongly recommend that you leave that oil in until the OLM tells you to change it. There must be a good reason for it.
