Break in oil ?

Wally world oil and a $8.50 bottle of GM E.O.S. break in, run for 100 miles and change. Dont use a hose to cool. Motor needs to heat quickly to seat rings. 2500 rpm 20 minutes, then run rpms up and down slowly. No compression braking. Drive under 4500rpm for first 100 miles. Should be good to go, many motors and cams, no failures yet.
