Yeah it's a made up number hence the " .. Say 80%"
Just because the manual doesn't say to replace the oils doesn't mean you should never replace them .. There are lots of manuals that say never to replace brake fluids, transmissions, etc.
I'd rather have a differential with clean flowing oil than one filled with gunk causing power loss
If you ever played with a magnet you'll know that as more things clump onto it the weak its attraction to other stuff
