I admit I'm running off of fear since all the Toyota guys say that you must
use either Amsoil or Royal Purple or Redline GL4 75W90 in the manual
transmission.

Even the Royal Purple 75W90 gear oil is $60 per gallon.

All I want to know is what's so special about these gear oils that they
cost $60 to $70 a gallon (where I need about a gallon)?

Looking up the gear oils, I find technical information but nothing answers
my question which is why I asked here.

The specific products you mentioned above are all synthetic lubricants
and cost more to manufacture, hence, they are more expensive at retail
than their non-synthetic counterparts.

The problem is Donald Trump. The solution is impeachment or, the otherwise legal
removal, from office, of the greatest threat to peace the world has ever known.

And Amsoil and Royal Purple are recognized brand names, that the
gear heads go gaga over, so you pay
more for them because they can get it, just like with other products.
You can find typically find synthetics from other manufacturers that
meet the same specs, but cost less.
