Food for thought posted Jan 14 by vtmetcheng under, "Honda break-in oil"
"Just to be the distrusting consumer... Cars like Hondas and Toyotas will run for well over 200,000 miles with correct maintenance, including break-in period. Now, remember that an overwhelming majority of automotive owners do not keep a new vehicle for more then 100,000 miles. What does this mean to the automotive manufacturers, well why should they care about miles after 100,000? As long as the car runs without problems for this time the customer is likely to be a repeat customer, still living in the mindset that 100,000 miles trouble free is a good car. I can tell you that an improperly broken in engine will last past 100,000 miles, see it every day [emphaisis mine, RH]. The fact remains that an automobile company will not want there [sic] car to last 300,000 miles because they are loosing money. What interest would they have in keeping you from their showrooms? Is anyone saying a high Moley [sic] count is bad in break-in oil, no, but wear particles [emphasis mine, RH] are. Some say, "just change the filter then," but you forget that filters only get larger pieces (larger being relative). The very small pieces that do get through are also able to get between parts (ex. main bearings and the crank), allowing aluminum and other particles in [emphasis mine, RH].
This is just something to think about in my distrusting mind. I could go on like this forever but had to make myself stop."
