Far Too many factors to make a blanket anwser for all vehicles and all situations.
My wife had an ancient abused 4runner with a pretty bad oil leak, I was bad about remembering to check it and she was bad about telling me the oil light was on, it routinely got 4 qts low on a i think 6 qt system, possibly 5 qt, thats about where the oil pressure light came on, it survived like this for many years,
Butt one day I was driving when it happened, I heard a faint pop, and some clattering noises for the few moments,, and it immediately lost power, drove it for a few weeks like that, and finally did a compression check, almost no compression on #3, other cylinders were good, I speculated it broke a ring or something, probably related to habitual oil starvation, no noise other than the few seconds of the event. No knocking, I drove it to the junk yard with the AC running on its 22 year old factory AC chage and 340k miles on the odometer.
Many of Toyota's motors are tough, also they are low stress to begin with, especially the truck motors,, plus my wife drives like a 90 year old grandmother, would a diffrent motor doing for instance amature drag nights or mountain roads pulling high G's at high power be as accommodating? Probably not.
Don't do what I did, keep it above the low mark on the stick.
