I have seen american V8s torn apart with 1500 easy miles and ridden hard with 1500 miles, the rings seat lower in the easy break in and when you ring it's neck the rings smack the lower"slow break in" seats in the cylnder walls resulting in lower power. I do not know if this applys in these modern tite clearance engines.

I will be running in my 370 when i get it, just how I ran my old XR6 Turbo (Aussie Ford)

1) Make sure engine is warmed up before going over 3000rpm
2) Alternate loading the engine up (full throttle) in 1st, 2nd, 3rd upto about 5000rpm, then back off and let it coast down, then repeat back up to 5000rpm. E.g 1st gear a few times, 2nd gear a few times etc (yes its very tedious)
3) do the above on roads with hills, so you are really loading the engine up.

When I did this on my old car, when it was stock, it had more torque than all the other same model cars on a dyno day I attended.

The car then was modified to 540hp with 750nm torque and had no oil problems at all.
