Don Ahrens (engine/race car/tranny builder, SCCA E prod racer for last 25+ years), told me @ 200 miles, change oil with conventional, another 2-300 miles change oil again, then another 500 miles, change oil again, then ride out on your last conventional oil change till you reach the total 1500-2000 mile mark, then use whatever type of oil you want, conventional or synthetic, i personally recommend Rotella T 15w40 for all intervals... shit's on point...

as far as driving, you want to drive it like a daily driver, don't romp on it, but don't take it too easy either either either, take it for a small highway trip, maybe 100-200 miles and just cruise. drive it as if you were borrowing your buddys moms car for the 1500-2000 miles...

after that, everything should be well seated, and broken in properly, then go rail on that motherfucker and enjoy all that hard work!!!

break it in right, it'll last forever, break it in wrong and well... deal with whatever comes your way...
