From the Manual:
"Here are some times when you might use Drive instead of Overdrive:
-When driving on a hilly, winding road.
-When towing a trailer, so there is less shifting between gears
-When going down a steep hill."
Overdrive is for normal driving. Use it. The transmission won't use overdrive until after it needs to use 4th anyway.
