what driving techniques saves fuel ?

Here are more efficient methods to save fuel while driving, given in bullet form for ease of understanding and implementation. 

1. **Smooth Acceleration and Deceleration** 

Try to avoid alacritous starts and abrupt halting whenever possible. If aggressive driving is practiced fuel efficiency on highways can drop by 15–30%. For optimal fuel-consuming practices, try to perform gradual acceleration accompanied with coasting to decelerate. 

2. **Maintain Constant Speed** 

It is recommended to set the cruise control when driving on highways (where the terrain allows) so that speed fluctuations are kept to a minimum. Altering your speed rapidly can waste fuel. 

3. **Moderate Speed Control** 

With an increase in speed, aerodynamic drag increases exponentially. For example, driving at a speed of 80 km/h vs. 12

0 km/h has the potential to improve efficiency by 25%. 

4. **Avoid Engine Idling** 

If you predict halting for longer than a minute, make sure to switch off the ignition. Fuel is wasted during idling regardless if the engine is running or turned off. 

5. **Assess the Traffic Flow** 

While coasting in gear, adjust your speed according to the traffic that lies ahead of you so that you can further avoid unneeded stopping (: fuel cutoffs in modern cars. This saves more fuel than both the neutral and braking processes. 

6. **Appropriate Gear Usage** (manual vehicles)

When engine strain needs to be reduced, overdrive gears can be used on the highways. For manual transmission, try to shift as early as you can, which will ultimately keep the RPM low. 

7. **Minimize Vehicle Load**

Try to remove any unused and heavy items, such as a roof rack or trunk items. If the weight of a vehicle is over 100 lbs, miles per gallon can drop by 1. 

8. **Routine Monitoring** **Tire Pressure**: 

If tires are underinflated by 10%, efficiency drops by 2%.

- **Condition of the Engine**: Ensuring air filters are clean, using the correct oil grade, and having working sensors, such as oxygen sensors, ensures that the engine's performance is optimized.

9. **A/C Usage and Drag**. 

Focus on using A/C only as needed, and keep windows rolled up while driving at faster speeds to keep drag lower than if A/C were used. When at low speeds, windows should be kept open.

10. **Planning Routes** 

Plan the routes to combine multiple trips to reduce the chances of cold starting the engine. Use applications for traffic and construction routes.

11. **Driving in a More Efficient Way** 

When possible, turn on "Eco Mode" if available to reduce throttle sensitivity as well as system activity. During driving, pay attention to fuel economy feedback.

**Tip for Fuel Saving**: Modern engines no longer need fuel flow while coasting in gear compared to neutral. This saving tip is better than coasting in neutral and allows on the road savings. Unlike coasting in neutral, there is also engine breaking that eliminates the need for brakes, reducing brake wear.

These fuel saving techniques, when combined with suitable driving practices, will lead to an estimated 10-40% fuel saving per journey, depending on how the vehicle is driven and what the vehicle is.
