I'm almost done replacing my small block. Do I need to use engine break-in oil? I'm in Indiana so it's pretty damn cold right now, so the prospect of using a heavier weight oil doesn't seem right. I know these engines have pretty tight clearances too.

My initial thought was to run break-in oil for the first 50-100 miles, change it out for 0w20, then change the oil again at 1k miles. All while following the manual's break-in procedure (under 4k, vary rpms).


Thoughts?


EDIT: I meant to post this in the Engine technical topic forum. Whoops.
