overdrive chooses the most fuel efficent gear but the savings will only be noticed on the highway. try not to use o/d when towing though, even on the highway. it's hard on the trans. YES!! Seriously? Just to add to the first two answers... Overdrive will kick in once the truck reaches approx. 55 mph. It shifts the transmission into a higher gear, which provides a higher output rotation at the wheels than the lower gears at the same input rotation/power. This translates into less work, and therefore less fuel consumption, to maintain the same speed. When the PCM determines that the truck needs more power rather than speed, it will downshift as needed. If you are towing, it will have to downshift more often, making for less fuel efficient operation. If you have a tachometer, glance at it as your transmission is shifting and try to track your RPMs as well as your speed. You will see that the RPMs actually drop when OD kicks in. The lower the RPM and the higher the speed, the more efficient the fuel consumption.
If an automatic car is in off overdrive does it save fuel
overdrive is used to save fuel economy at cruiseing speeds,for freeway or open roads.
its acruising gear on all fords whether manual or auto so you save gas and your tranny goes into a higher gear, less torque on tranny
If it has overdrive use it! it is a "highway gear" it will make no difference what so ever until you get up to speed then it will shift into overdrive and save you gas!
Yes it should, its very important.
Safe but unnecessary. The trans will be constantly shifting in and out of overdrive in traffic and will put unnecessary wear on the transmission. Save it for the freeway.
Overdrive engaged saves fuel.

If your vehicle has an automatic transmission with overdrive, then at speeds above 45 mph, it should be in overdrive, which reduces engine RPM's to save fuel.
