I found this topic over at the ARX Tech. Talk Center. I think it speaks volumes about the contaminants that can form during a new motor break in period and an owners proactive approach for a very young motor.
Engines With Low Miles Don't Need Auto-Rx ( Think Again)
When my Mercury Marauder hit 15,000 miles I put Auto-Rx in and changed
the oil again at 20,000 miles, I remember the oil was a little dark and
the oil filter was a little heavy at 20,000 miles, now at 15,000 miles I
added a Maintenance Dose, and did the same thing at 20,000 miles. I went
to change the oil today at 25,000 miles and the oil came out darker than
before and the oil filter felt like a brick. I bought the car with
10,000 miles and changed the oil right away even though the previous
owner had changed it at 8000 miles, he did his 1st oil change at 3000
miles. Obviously a new engine should be clean, this proves to me that
junk is building up inside new engines in a relatively short mileage
time, I love reading posts on another board which I will not name where
individuals say " My engine only has ( 50,000 , 75,000) miles so it is
clean." I changed the air filter at 10,000 miles and again at 20,000
miles and both times the air filter was hardly dirty, I also changed the
fuel filter at 20,000 miles, so it is not like the only thing that has
been done is oil and filter changes.
