Wash your car more regularly. (clean cars are more aerodynamic)
Remove extra weight like luggage, golf bags etc. when driving on an everyday basis.
Don’t drive with open windows. (More air resistance)
Tyre pressures and wheel alignment
Check that your tyre pressures correspond with your allowed pressures for your specific vehicle.
Running pressures closer to the full laden pressures will improve fuel consumption but will detract a little from your ride quality.
Find a balance that you are happy with.
Make sure that your wheel alignment is within the allowed tolerances allowed by the Manufacturer.
A vehicle tracking straight ensures less rolling resistance and thus improves fuel economy.
Choosing your routes (Shortest and most flowing)
Choose the least congested routes.
Choose the most flowing routes.
Always choose the route that includes the longest stretch of highway driving.
The shortest route might not always be the most fuel efficient.
A Relaxed attitude improves fuel economy.
Ensure that you leave early enough for your next destination so you would not need to drive faster than what is needed.
Be more patient when driving.
Stay within the legal speed limit restrictions at all times.
Be smoother with your throttle applications.
Always accelerate at a moderate pace.
Always maintain momentum.
Always use higher gears.
Pulling away and slowing down
Pulling away burns a lot of fuel.
Therefore we must try and stop as little as possible.
When pulling away apply as little throttle input as possible and let the vehicle gradually accelerate.
Again, be smooth with your throttle applications and never push the accelerator deeper than is needed.
Some vehicles have a lot of low-down torque and second gear instead of first gear could easily be used for pulling away, especially if the vehicle has not come to a complete stop for example at a yield sign.
Reading the road
By looking further ahead you could make decisions quicker, thereby maintaining better momentum and thus saving fuel.
Make use of declines before inclines to improve your fuel consumption.
Carry more speed down the hill to use the extra momentum for the upcoming incline.
Try and avoid accelerating on inclines, as this burns a lot of fuel.
On declines the least amount of throttle is necessary to maintain your speed and in some cases no throttle input is needed at all. Make use of this to be more fuel efficient.
Choose the most flowing roads.
Maintain momentum as often as possible.
Know your vehicles capabilities, so you can use the highest gears possible.
Always accelerate slowly and use as little throttle input as possible.
Stay within the legal speed limits.
If possible, always use cruise control as newer vehicle’s complicated systems are more than often better at keeping a constant speed with minimum throttle application than most average drivers.
Maintain a safe driving distance so you can maintain your speed with the least amount of decelerating and accelerating.
Driving in Traffic
Flow with the traffic.
Always accelerating smoothly.
Beware not to be too hard on the throttle to close the gap to the vehicle in front of you.
You know the vehicle in front of you is going to stop within a few meters, thus just let your vehicle flow behind him as slowly as possible to ensure that you might not have to come to a complete stop, but rather just a crawl.
Use the highest gear possible. (Easier in vehicles with good torque characteristics).
