I think anything earlier than 1,200 is too early not because of mileage, but because there're NINE qts of oil in there, and the filter is larger than most as well. Yes, some particles will get past the filter, but short of doing 2 oil changes at 600 and 1,200, I much prefer one at 1,200 than 600, for the simple fact I rather have particles floating around 600 miles than 15K miles (or 7.5K, like most people do).
