Default Oil change after break in

What’s a good oil to run after break in? Street/strip Carbureted 6.0. Did like 4 passes on dyno. Or do I need to leave in longer??

I run "break in oil" for the first 1500 miles,,
But change it the first time at about 500.

Several sources sell the high sulphur/zink that will help cam and lifter and rocker contact pints burnish and harden faster.
Roller rollers have made it less important than it is in some engines. IT also helps the timing set mate up.

Don't run a new motor on full synthetic, switch to full synthetic after the rings are well seated.
I've used the semi synthetic blends and they seem to work well for those first couple thousand miles.

Also make sure your using a reasonable viscosity for the parts you have in the engine,
IE: If your running low tension rings you need to run one of the lighter weight oils or the rings will not hold
compression and or foul. (I have one engine that uses 0W-20,, good pressure and runs great.)
I also have a engine set up with Heavy rings, and it gets 20W-50, with lighter oil it eats oil like a pig..

YMMV
