When to use over drive?

Overdrive should be used when driving at higher speeds, usually above 50 mph, on highways or open roads. It helps improve fuel efficiency by reducing engine RPM, resulting in less engine strain and better gas mileage. Avoid using overdrive in situations that require frequent acceleration or deceleration, such as in city driving or hilly terrain, as it can lead to poor performance and increased wear on the transmission. Always consult your vehicle's manual for specific guidance on using overdrive.
