392 6.4L Hemi Recommend Engine Break-in Procedures?

[Jeepstin392]

Changed break-in oil out at 1369 miles...never has used a drop...oil was clean and clear...broken in at 80-83 miles per hour >3000 rpm....

The break in oil has zinc additive to assist in seating the rings to cylinder walls. Also, break in is tI’ll 500 miles, varying speeds, no full throttle launch, etc.
Hopefully you did it properly and have a solid break in.

Varied rpm’s and speed when forced to on I-10 and I-45 all the way to DFW…but mostly at 80-83 mph…it has not used any oil at all so rings are seated for sure…

I'm doing my break-in by the book....why take chances? Of course doing 55 mph on I-10 was quite an adventure.

Currently just passed the 300 mile mark, so need to bone up on the 300-500 procedure.
