Dear rawkeron,
Here I am mentioning the general points to be kept in mind for better FE.
- Park your car properly. Park your car under the shade of a building or a tree whenever possible. Parking in the shade will keep the inside of your vehicle cooler, which can help you minimize use of air conditioning.
- Fill Petrol during the coolest time of the day and fill from trusted petrol pump. Don't forget to do the fuel quality and quantity tests.
- Ensure the tyres are at the correct pressure and wheel alignment is correctly adjusted.
- Observe proper maintenance. Regularly servicing of car ensure best performance. A clogged up air filter can result in low FE. Dirty oil can cause friction and can reduce mileage.
- Minimise unnecessary weight in the car. Extra weight reduces mileage.
- Don’t start the vehicle until you’re settled in: seat, seatbelt & mirrors adjusted; passengers settled in as well.
- Plan your journey. Avoid congested roads that are under construction.
- Avoid driving, if possible, in rains as water on roads increase rolling resistance. - Avoid driving if possible during the peak temperatures of the day when use of the air conditioner is required.
- Change your driving habits. Leave early to avoid traveling during peak hours. Also, combine small trips and household tasks. Every time cold engine is started more fuel is burnt.
- Don’t idle your engine to warm it. An idling engine gets zero km per litre. Start to drive immediately. It’s a more efficient way to warm the engine and entire drive train, including tyres.
- Don’t start the engine until there’s actually an opportunity to start driving: e.g. a gap in traffic when exiting a driveway or parking space. Accelerate gently from stand still at traffic lights etc. Drive smoothly in traffic. Look ahead to maintain appropriate distances and speeds to avoid heavy braking and acceleration. Speeding up to the car in front and then applying the brakes wastes fuel.
- Slow gently into corners if required then exit on a light throttle. Shift gears sensibly. Shift up as soon as you can without lugging the engine. Always accelerate in a smooth movement and travel in the highest gear possible.
- Air conditioning requires a lot of power. Use it sparingly. Driving at city speeds, you’ll save fuel by using your flow through vents and opening windows.
- Drive with windows up at higher speeds to minimize aerodynamic drag. A constant 90 km/h is better than drifting between 80 km/h and 100 km/h. Minimise full throttle over-taking maneuvers.
- If you have no pull-through spots to choose from, reverse in when arriving, instead of driving in when warm and backing out/turning around when the vehicle is cold and fuel economy is at its worst.
- Your ability to drive efficiently depends on being able to anticipate changes in the driving environment. The way to do this is by constantly scanning well ahead in your intended path. In city driving you should know what’s happening at least 10-15 seconds ahead. On the highways, at least 30 seconds visual lead time is appropriate.
- During driving a slower paced music is more relaxing and tends to promote a more sensible driving style while also reducing stress. While fast paced music can make a driver more impatient, more aggressive and likely to speed.
I am sure you can increase FE upto 20% by follwing the above tips.
