engine break in

"Run it in...... or Run it out"

Just gotta load it it up - plenty throttle around peak torque - I wouldn't be redlining it but def plenty of load, and as above, don't be shy with the engine braking. I usually go up the motorway when its quiet in 3rd and accelerate from 60-100kmh and engine brake back down a dozen times or so

Sounds like it doesn't matter...

This

Peak torque gives max cylinder pressure = max force pushing rings out to contact cylinder wall to wear the peaks off the crosshatch pattern

Engine braking helps to suck oil past the rings to lubricate, cool everything down a bit and help wash any metal away

Biggest threat is heat as extra friction in the first minutes of the run in could overheat things
So avoid max revs, 80% is fine for the first 20 mins of driving
