Dude, that's just over 3,500 miles... no properly built engine should burn up over 3 qts of oil in that short an interval

I'm SO glad my wife trusted my engine-building experience and let me break our Z in quick and hard.

You are a fan of the "hard break-in" approach?

I'm really not sure what to believe, especially given that there is probably some break-in done by Nissan before assembly... can you detail your break-in method?

Also, is this for new cars (that might receive some factory break-in first) or newly built motors (done by you or a shop)?
