Differential Fluid

My 1995 C280 has 95k miles on it. I had completed a 30k service at the 90k interval, except I had not completed the fluid change of the differential. Today I purchased some Valvoline Gear Oil, a synthetic blend. I left my car next door at the mechanic while I work to change it.
I have a few questions... what are the benefits of changing the fluid? The bottle even said Improved Fuel economy? Is this so? Probably VERY minute I'm sure. I wonder how dirty the old stuff is...
