Automatic Transmission Fuel Economy Tips
We all know that driving a manual is extremely beneficial to your gas mileage as it allows you much greater control over your engine. What you may not know is that there are quite a few ways to achieve the same control over your automatic transmission. Check them out:
When cruising, drive the the speed that allows the lowest RPM for the speed zone you are in.
EG. if the posted speed is 30 and your car shifts into 3rd at 35, you may be able to achieve the 3rd gear shift, then reduce and hold 30 without causing a downshift.
Drive at the speed that allows the TC (torque converter) to lock up. This is often around 40-45 mph. Speeds just above this typically return the higest cruising fuel economy.
Shift automatic transmissions to neutral when stopped (assuming you’re going to leave the engine running). Remaining in drive wastes fuel as the engine continues to try to creep the car forward while being held back by the brakes.
Some automatic transmissions can be coaxed to upshift sooner when accelerating by briefly releasing some throttle pressure, then re-applying to continue accelerating.
If your transmission has an “OD” (overdrive) button or position, leave it engaged to ensure the transmission will shift into its highest gear as soon as possible.
If your automatic transmission has a “power/economy” button, leave it in economy mode. This usually results in earlier upshifts and later downshifts, saving fuel.
These tips if followed will greatly increase your gas mileage.
