no flush, but i wouldnt recomend keeping the syn in for too long on the first change, maybe change after 3000. then work your way up to normal intervals

another mind flooded with false information.

Oil is oil. Change it whenever you want, how many times you want, swap back and forth however many times and whenever you want.

Amsoil 5w-30 with Amsoil Ea057 filter, I go 10K at a minimum. I went 11,476 on my last change, and the oil looked like it was barely used.

5-7K sounds fine for you. Just use a good oil filter. Amsoils filter costs about $15.

I've heard more bad stories about K&N oil filters than I really want to dig up. OEM filters do a better job than they do.

$15 every 10,000 miles+ is very worth it to me. VS spending about $6 for an OEM filter from the dealer changing every 3,000.
