Some may call me crazy and others will just nod their heads and say "yep, woulda done the same thing". Being the gearhead that I am (aerospace engineering and precision gear system engineering are my chosen profession) I guess I just couldn't help myself... so, I did a break-in short oil change on my new '13 SCrew XLT Eco at 1465 miles with the idea that *most* of the nasty break-in residue and such would be removed before it had a chance to affect the inner workings of the engine and trans. What you will see attached are the baseline analysis reports from Blackstone Labs (shameless plug inserted here... with a disclaimer - I have no affiliation with them, I was just *really* impressed with their service and how quickly they turned my order around). I am happy that the results were deemed well within normal ranges with only the expected spikes in copper/brass/bronze and silicone, and again impressed with the personalized comments that their lab tech included on the report. So, for those thinking about doing something like this, you can't go wrong if you decide to run a short oil change at break-in. It's more a matter of economics (cost of the change over + cost of lab testing) vs. your personal risk tolerance of potential future issues 5K, 20K or 50K down the road by leaving the stock fill in (especially in the trans).
