Interesting - I did not know about the crosshatch pattern on cylinder bores to profile the piston rings. I noticed the website mentions that the first 20 miles are most critical to overall engine life. I picked my car up with 24 miles so... guess it doesn't matter?! In addition, I have a problem directly comparing motorcycle engines to car engines. Yes, they're the same concept.. but can one honestly assume that what's good for a bike is good for a car? 14,000-16,000RPM redline vs. 7500RPM redline? Different weights of the mechanical components, different pressures, etc. The website does offer compelling evidence though. The debate lives on... I'm sticking to my guns though
EDIT:
Something else I just thought about. Here in the industrial plants we have high speed gearboxes all over the place for equipment. Any of you that have replaced transmission/differential oil have probably wiped off the metal shavings that collect on%
