I would suspect it's not actually gear oil, though it's possible it sheared that much. The gear oil from my dad's Allroad came back at 9.92 cSt after 145k mi.

Many MTLs these days are just liquid delivery systems for anti-wear and friction modifier additives, and are really thin. OEM lubes from VW, Honda, GM and Ford are all like this. The commercial version of the GM fluid is Pennzoil Syncromesh. I'd bet the dealer used a MTL rather than gear oil because they didn't understand (or didn't care about) the unique requirements of a Subaru AWD gearbox.
