You should leave the car in overdrive at all times, unless driving conditions dictate otherwise. The overdrive is intended to optimize fuel consumption.
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!
The car is normally in overdrive. When you press the button the left side of the gear shift then there should be a light on your dashboard should come on saying o/d OFF.
If an automatic car is in off overdrive does it save fuel
keep the overdrive shaft button pressed, there is a panel light called "O/D" that should light indicating the overdrive is OFF. In that case make sure the light is OFF which means overdrive is ON.
the transmission is in overdrive I don't have overdrive in my car but look at your gearshift because the small button on it should be how you disengage the system
if you have overdrive in that car it means that your about to go into overdrive
Most vehicles, for safety reasons, will not start in overdrive. The vehicle must be in park or neutral for a properly working starting sequence to work.
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.
Keep your horse and get an old car. :)
The car needs to go into overdrive unless you are towing something heavy which makes it shift between overdrive and non overdrive. It is better to allow the car to shift into overdrive.
Overdrive is the normally allowed position in a Ford Explorer automatic transmission , once the vehicle speed is fast enough ( my Ford Explorer is 50 MPH ) the automatic transmission will automatically shift into overdrive
