3000 miles before syn... i would really do 5k no need to switch early. motor can still be broken in 1500 miles. i have had a few poeple with 1400 and the motor was still very weak. had to be rebuilt and rehoned because of syn being used to early.
ever get your tested i bet you can go a lot farther than 6k if you have the right oil.
