Guys do you even know what an Over Drive gear is? In manual cars its the highest gear available. it is also called a cruising gear. If your car is 5 speed then 5th is your over drive gear. In automatic cars it is the highest calibrated/ tuned gear. In fact there is no highest gear but merely an adjustment in ECU to realize highest gear. Some like to call it virtual gear.

Under normal circumstances the OD button should be OFF. City driving u do not use OD at all. Only when you are travelling on constant speed u should use OD. In city driving if you use OD on, use more fuel. That is why some people reported high fuel consumption in their automatic cars because they do not realize how to use OD mode. Until they realize it they go

"Oh Dang!!!"
