New vehicles have roller valvetrains unlike older flat tappet set-ups.
The changes in oil additives has rendered the typical off the shelf oils insufficient when breaking in a new motor w/a flat tappet valvetrain. The additives that used to protect the valvetrain during break-in were banned by the EPA. Roller valvetrains do fine w/o the additives.
No additives in the oil can wipe the hardend surface off the cam lobes & the lifters will wear into the lobes almost immediately.

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....
Cubic inches is like Indiana Jones with a cheap pistol.
