The viscosity stability of synthetic gear oils should return better efficiency in cold conditions. It's an issue for transmissions/differentials, since they don't benefit as much from the heat of combustion as engine oil does.
I can find dozens of links that claim to support this notion.... but can I find one on short notice that appears to have some science behind it? Nope!
Anyone?
