I admit I'm running off of fear since all the Toyota guys say that you must

Forum "blowhard know-it-alls" are a dime a dozen. I use whatever the mfg recommends.
The problem with older cars is that what the manufacturer recommended has
likely been unavailable for decades.

We have this issue with motor oils that don't have the ZDDP levels that
older lifter designs expected.

Oh, if you are trying to make this vehicle last forever, quit being such a tightwad and buy the Amsoil.
