Parts are not machined perfectly, there will be extra wear in the beginning as pieces mate with one another and wear into each other. I say get the oil out soon with those contaminants instead of letting them circulate.
The factory fill is synthetic. I don't know what the additional additives are, but nowadays they're using Penzoil just like they used to use Mobile 1.
I can believe that assuming they have come up with something to get the rings to seat.That is also why it is important to keep the break in oil in the engine for as long as the engineers say it should be.
Don't the rings seat within the first few miles of running the engine under a moderate throttle (cylinder pressure)?
As you know the first few hundred miles on any internal combustion engine is critical.An engine needs an amount of duty cycles[hot,cold,hot,cold] for a proper wear in process.So i would say an engine definetly needs more than a few miles.
Great post ltleo and I agree on all points! One of the first things the SRT engineer told me when he delivered my Jeep was to watch the oil closely on these things. All of us should be going by the Schedule B for maintenance and that means change the oil every 3 months or 3000 miles whichever comes first regardless of what oil analysis says. Never met anyone who would qualify for a Schedule A maintenance either. Doesn't matter if you change it yourself as long as you keep the bills, but they will deny warranty claims if proper maintence is not done as you know already.
