I once sat down on a full open tube of high temp anti seize with predictable results  ::)

Need/needed is a funny term. No lubricant is needed in an engine. It will run for maybe a minute without any and for years with the cheapest oil you can buy. It all depends on what sort of life you are hoping for.

I've written about moly before but I'll do it again.  :BEER:

Friction results in heat. If the rear drive runs cooler with it than without then there is less friction. Simple!  ;-T

I use mineral oil in all of mine and the rear drives run cooler with moly or its equivalent tungsten disulphide. I can measure the difference with an IR thermometer.

Give it a try. Go on. let's be scientific.  :BEER:

And interesting enough, although my owner's manual says to use molykote the Technical Data Sheet I linked above from Moto Guzzi Service does not even for the models going back to the early '90s.  

Tech Note 010-2006 (re: Lubricants) also says nothing about adding moly to the "gearbox"  ::) of any of the models listed, including my hydro EV, even though my MOM says to add it.  So does the Tech Note supersede the manual, or did those crazy Italians simply overlook their own specifications?  In this case I choose to go with the advice I got in the MSF BRC:  "Always listen to your MOM."  It's not that much of a burden to add a shot of moly, and it can't possibly hurt.

Also, since I am using the same gear oil in the transmission and the rear diff, I choose a mineral oil.  Maybe it will help keep that plastic bearing cage in the transmission intact, maybe it won't.   :-\

Amazingv how a final drive became a transmission.

Well, it DOES transmit power from the gearbox to the wheel.

 Have you made comparisons with different brand oils or synthetics without the moly additive?

Oh by bike:

That's useful!  Saved to my library, thanks!  Now if I can plot it out on a 24"x36" sheet, it will hang in the garage.

Interesting, "gearbox" and "transmission" refer to transmission and final drive.  What's in a name?

Except MG is not even consistent in their translations.  In that 2006 Tech Note, "transmission" is transmission, and "gearbox" is rear differential.    :o

Ok,  What to call it?  Transmission? Gearbox?  Bevel box?  Final drive?  Not-a-CARC?  I give up.   :P

Except that the guzzi does not use a differential on account of there is only one rear wheel -- nothing to differentiate.

So it is a definite yes and no? I think the component in question is scientifically called a '90 degree rotational redirecting, reduction, bevel geared, energy transmitting, all metal, in an oil bath mechanical device'. Thanks for everyone in clearing up / muddying the water advice. You guys are hilarious!!! Even if nothing concrete is decided on, it is very entertaining.  :pop
