Red Line has said "not for break-in" for many years on the bottles I've seen.
The moly being used again in this viscosity grade is interesting.
It does bother me from an honesty standpoint that they list API CJ4 because that limits the sulfated ash to 1.0%, and judging by the concentration of metallic elements I see here, I highly doubt its sulfated ash would be 1.0% or less.
The flashpoint is much lower than I expected but perhaps the test result is in error.
