an engine is an engine. sure, they say baby it the first hundred miles, try doing city driving instead of highway... at one point it helps, but how much ? statistically saying, maybe that engine would run 2% better that others...

if that is not a matter, drive it as you like from the very first mile. it's my advice as a mechanical engineer, two things seems to be important: use mineral oil for the first thousands miles and never rev high a cold engine.

rage2: what you are saying is all about the oxygen sensor, the hotter it gets the faster it starts work at his normal range
