I just hit about like 670 miles what do you guys think? Wait till 1000?

 

Yet another thread on this topic, but I'll post what I did.
From new to 500 miles, I never went on the highway and varied my rpms, and also never revved above 6k or so. I changed the oil at 500 miles just for piece of mind and ever since then I've been letting it rip. So far it does not burn a drop of oil, even during the "break in" i checked it often and it never appeared any lower on the dipstick. Current mileage is 6,323.
