Ive been asked this kind of alot VIA texts and it was pertaining to how i broke my motor in i did the following:
first start up (when doing coolant/cleaning up) ran SAW30 Oil (non detergent)
Drained oil/changed to 5w30
Ran it like i stole it in gears 2,3,4 taking it from 2500 to redline (6500, limp mode was engaged due to knock sensor vtec etc.) Engine breaking is a must as this helps create vacume which helps seal the rings.
This is done for 20 miles
Did a compression test at 200 miles and compression is still building, it takes about 1500 miles to do fully,.
