Overdrive as the name suggests is like having one or multiple more wheel rotations at a specific engine speed. In simple language it helps the engine run at lower rpm(lower revolutions per minute) and helps you save the fuel.
When the system was put into production, then at that point of time overdrive had to be selected manually with independent lever. This was because of the relatively poor engine power. One can select overdrive only after hitting the highway and once he/she had build up enough speed.
As the technology changed overdrive came fitted in the gearboxes. Now the technology is so advanced that overdrive is selected electronically. The sensors detect the need for overdrive and even before you come to know overdrive would have been selected. You dont even feel. Now thats technology

The exact answer is... it depends. If you shift too early, the engine has to work harder and mileage and engine life are affected. If you stay in a lower gear than you need, the engine is turning much faster and using more fuel. If you have a manual, don't use overdrive in town.

It allows the engine to turn slower at highway speeds.
New cars do it electronically inside the transmission.
Years ago there were cars that had an overdrive that worked mechanically with a lever.
The principle behind it is to allow the engine to turn slower and use less fuel while causing less wear and tear. It also reduces noise from the engine.

A number of the Potential benefits to Choosing Fluids Like Resource?
In summary, this approach cutting edge van resource cutting down end boasts a capability to store gas content just by even though 80 percentage point. An alternative advantages is normally a lot less fractional co2 emission and therefore the sole just by unit from this model is normally normal fluids.

all answer is true. I will add that the car is allways in overdrive. if you take if off overdrive, a light will light up and if you step on the gas, you still go slow and will not change gear. Turn if off if going up a hill or heavy loaded.

it is like a higher gear, it makes the engine rotate easier, therefore conserving fuel..
