Overdrive is basically the cruising gear. In a car with an automatic transmission, you can drive in OD all the time. You should be driving in OD anytime you are traveling over 40-45 MPH. (This is the speed at which your car will automatically) shift into OD if you have it placed in that gear to start with. OD saves strain on the transmission and I would speculate the drive train, also. Your car will coast more easily in OD and use less fuel. The only time I consider not using OD is when I am in town at speeds under 40 MPH.
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!
Almost never. It is used to disable O.D. when heavy loads and speed are causing the car to jump in and out of O.D. repeatedly.
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.
For most drivers, Overdrive should be used full time. Its designed to reduce the amount of effort the engine needs to maintain speed. Whenever a lot of shifting is taking place, its recommended to only used Drive. Roads with a lot of hills, curves, or heavy traffic areas should not use overdrive to prevent damage to the transmission. Also, disengage overdrive whenever towing. There is not enough torque generated by the engine to tow while in overdrive. Towing while overdrive is engaged can cause damage to the engine and transmission.
If an automatic car is in off overdrive does it save fuel
I believe overdrive should automatically be enabled on any car. Overdrive allows a car to drive at fast speeds with low engine input (low revs) resulting in better gas mileage. The downside is that you lose torque. You should be able to turn it off for things like climbing mountains and using engine breaking to go down them. Unless you turn it off, it's already 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
Yes, you can use overdrive in your car when driving in the snow. Using overdrive helps the car maintain better traction in slick and icy conditions.
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.
