The same one that was used for the same protection back before the
catcon was in wide use.  zinc dialkyldithiophosphate. Only problem is
that is poisons the catcon in large amounts and can cause deposits on
the plugs and valves.

Yes, but an oil with a higher film strength and higher breakdown temperature
will last a little longer when the oil circulation stops.  That might not
be enough, but it improves your odds a little bit.

Consumer Reports tried to verify a claim made by Prolong where a person
drove a car  treated with Prolong forr 4 hours and 40 minutes without
oil and stopped only because she wanted to grab a bite to eat.  They
took a pair of factory rebuilt GM 3.4L V-6 engines, treated one with
Prolong, and ran with the oil plugs removed.  Both seized
simultaneously after just 13 minutes or 5 miles.

back when, before the ptfe craze, bardahl had an oil additive that I can
attest to it's merit.

this is a case where a limp-in mode provided by the bardahl additive
saved the day.

after knocking the drain plug out(losing the oil) in a 12 cylinder
graham-paige automobile w/bardhal additive in the crankcase -

it was able two travel 2-3 miles without any noticeable damage.

to my knowledge this product is no longer available - off the shelf.

Whatever one thinks of its virtues or vices as an additive, STP is a
good mnemonic. Safe place to stop, Turn off the key, and Pray you
haven't spun a bearing or seized or galled the heck out of anything in
the time it took to do even that.

Also STay off the Power, assuming you can get through traffic and come
to a safe place without it.  (Safety first -- live to buy another
engine.)

And you definitely shouldn't try driving off unless you know what the
problem is and can be positive that you've solved it.

It probably helps to have an engine that is more robust in these
regards (good luck figuring out which ones those are, besieds which,
prioritizing the ability to survive a low-probability failure is kind
of a goofy way to select a car).    Definitely helps to have quality
oil with a lot of shear strength at the molecular level and a good
ability to withstand temperature and a tendency to stick tenaciously to
metal.

I'm partial to STP no matter what others say. Unless it's an all out
emergency, when the red light comes on, the key goes off.

There is some basis in fact in STP.  It is a high molecular weight
polyalphaolefin
(higher than the PAO's used in synthetic lubricants) and is known in the
lubrication industry for some of its unusual properties.
