Here’s a simple window trick to save fuel while driving, used by many for better mileage:
The Foolproof Window Technique
1. Keep Windows Up on Highways
- At speeds above 45–50 mph, open windows create air drag, which makes your engine work harder.
- Keeping windows up and using AC moderately is often more fuel-efficient than driving with windows down at high speeds.
2. Open Windows at Low Speeds
- In city traffic or slow driving, air drag is minimal.
- You can crack the windows open to keep fresh air and turn off the AC, saving fuel.
3. Combine with Smart Driving
- Maintain steady speeds – avoid rapid acceleration and hard braking.
- Remove unnecessary weight from the car.
- Check tire pressure regularly – underinflated tires reduce fuel efficiency.
Extra Tips
- Using the AC efficiently at moderate temperatures can sometimes be better than windows down at high speeds.
- For hybrid or small cars, windows up is almost always best on highways.
- Avoid using AC when stop-and-go traffic is minimal; open windows work fine at low speeds.
