Extended drain intervals.
You can get different weights (you can't find conventional in 5W50 or 10W60, etc)
Apparently they increase mileage and don't break down as fast. The only reason why I went for "synthetic" was because of the viscosity. The KA loves the heavy stuff, but I also didn't want to run too thick of an oil at start up (15W40)
That is why I went with the 5W50 Syntec. I also hear that the Shell Rotella 5W40 is good stuff too, not the diesel stuff, but the gasoline stuff as there are way to many detergents in the diesel oil.
