I've read <i>opinions</i> that many new cars come with synthetic and that should be pulled from the crank and he first 500-1000 miles still driven with dyno oil to improve ring seating. But no mfg is going to suggest that. Otherwise I still think old adages
are wise, very engine speed and minimize load for first 500 miles and an early oil change. Also depends on what your plan is. A lease car that you keep 30-50k, it won't matter for that. But could be a significant impact in oil usage and performance when
it gets past 100k.</div>
