When to worry about engine noises?

Ime off the shelf synthetics are dog piss. I don't mind the statement about straight 30w....street car. Oil viscosity calms down warmed up, not a max power deal.
Racing, don't want it hot...want the least hp eaten up...5 20w.
Either way the oil psi would be higher than what he has.
Look forward to reading the cause of the issue once figured out.
