No. Not usually. Look at your tachometer (sp). A car will usually cruise (cruise control) on flat land at about 1.2 to 1.3K rpm at about 70 mph. I have had cars that cruised in this situation at about 9,000 (9K) at 70 mph on overdrive. That simply means that the car is traveling at the same speed on 1 or overdrive, but the motor is working less in overdrive. I got 38.7 miles a gallon on my 1995 Buick LeSabre 6-cylinder. When you come upon an upgrade (hill), notice that the transmission will kick into a stronger gear to make the climb, the rpm increases to keep up but the speed stays the same (70 mph). When it completes the climb, notice that it goes back to overdrive, the tachometer reduces in rpm, but the speed (70 mph) remains the same.

Turning off overdrive can actually lead to increased fuel consumption. Overdrive is designed to allow the engine to run at lower RPMs while maintaining speed, which improves fuel efficiency. When overdrive is off, the engine runs at higher RPMs, using more fuel. Therefore, it's generally more economical to keep overdrive on during highway driving.

When do you use your overdrive in your Lexus es300?
In a Lexus ES300, you typically use overdrive when driving at higher speeds, such as on highways or open roads, to enhance fuel efficiency and reduce engine wear. Engaging overdrive allows the transmission to shift into higher gears, optimizing performance and conserving fuel. It's advisable to turn off overdrive in situations like towing or driving on steep inclines where more power is needed.

The overdrive is designed for speeds after 50 mph so your overdrive should not be engaged until you are driving on the highway. The overdrive gear is designed for fuel efficiency and does nothing in town.
