Right. Overdrive is basically a downshift to generate more power at higher rpm's. A more detailed explanation is
here.
In my automatic, that has no gauge, I use moderate throttle to get up to the highest gear as soon as possible (lowest mph), continue moderately accelerating in high gear (not overdrive), then shift into neutral and coast. The object is to keep the rpms as low as possible for the speed.
I would probably watch the instant mpg gauge carefully to see how to adjust.
