How would YOU break-in your new engine???

Much of the Subaru community recommends switching from dino oil to synthetic after about 10-12k miles in a brand new Subaru. I guess it depends on the manufacturer.

i bought my STi brand new and the manual recommended not going past 4k rpms in the first 1k miles. that was the most disciplined 1k miles i've evAr driven. as lee stated, i switched from mobil (dino) drive clean oil to mobil 1 at the 10k oil change. i havent noticed much burning or loss of oil so i can only assume that things are working well thus far.
