There is a forum member over on the Pilot forum who just responded to an owner who lost his engine with 118000 miles on it. This member has posted this statement which I find to be, well for lack of a better word, hogwash!
"This seems like oil starvation. It will take a full tear-down to identify the source of the metal fragments, but I would bet on rings. Quick changers don't give the super hot engine internals a chance to cool down to ambient (room) temperature before refilling with cold oil. That causes thermal shock, which some brittle metals (rings) don't cope well with.
...
That's why I do my own oil changes, and always let the engine cool off at least one hour while letting every last drop of old oil drip 💧 out into the pan, then pre-fill the new filter also to prevent oil starvation on the first start."
First, engine internals are not going to cool down to ambient temperature within one hour. Adding oil is not going to cause thermal shock on "brittle rings", correct.
Here is a link if you want to read what happened to the owners engine and some of the discussion so far.
