"boraticus, you seem to be the only one that doesn't notice an abundance of glitter in new OPE at the first (and 2nd and 3rd) oil change."
That might just possibly be because I actually look for it and if it's not there, I'm satisfied with that.
Don't confuse me with some anal retentive, oil brand fanatic incapable of discerning reality from say-so. I've owned and worked on small engines for decades. I was also, in my youth, formally trained as a diesel mechanic. Accordingly, I have a fairly good grasp of mechanics and maintenance.
I've never said to avoid doing the 5 hour oil change. As a matter of fact, I recommend it. That's where you get the info you need to read the oil. What I'm against is all of the fanatical recommendations and endorsements advising participants to do multiple short duration OCIs. It's unnecessary and wasteful.
If numerous short duration OCI's were essential, one would think that every engine manufacturer, large and small, would be telling us to do so.
Far too many participants encourage unnecessarily wasteful/expensive oil maintenance practices. Myself and other like mined people need to temper this questionable guidance and try to provide alternative opinions that steer a course for sensible, realistic maintenance that is more than adequate for the engine as well as cost effective.
You can change your oil every ten minutes if it makes you happy. However, to encourage such a practice would not be of any use to anyone looking for engine break in information.
