1. Plan your route
Before making the trip, do take some time to plan your route so as to avoid traffic jams and congested roads that could increase the fuel consumption due to excessive idling that the car undergoes while waiting in traffic.
2. Do not speed
Drive at or below the speed limit. The faster you drive, the higher the air resistance and thus the higher the fuel consumption, ranging between 5 to 20 per cent more than when you drive at the speed limit.
3. Accelerate moderately
Flooring the accelerator when the light turns green to accelerate quickly away only serves to worsen the fuel economy as the engine would need to work very hard to not just get the stationary car to move, but also to propel the car forward quickly. Hence, it is a good practice to just accelerate steadily at a moderate pace.
4. Shift to the highest gear when possible
Shift to the highest gear when possible because the highest gear brings about the lowest engine rotating speed at a given speed compared to the lower gears. This in turn means that the fuel consumption in the highest gear would be at its lowest.
5. Anticipate traffic conditions
Every time the forward motion of the car is being opposed (applying the brakes), the acceleration you've already used (burning of fuel) is wasted. This means that fuel is being wasted everytime the brakes are applied. By learning to anticipate the traffic conditions up ahead, the usage of the brakes will be reduced and this directly translates into minimum wastage of fuel.
6. Keep windows closed while driving
When driving at highway speeds, do keep your windows closed as this will ensure that there will be no increase in the aerodynamic drag, which in turn translate into enhanced fuel efficiency.
7. Reduce the use of air-conditioning
This is probably the hardest tip to be applied. Air-conditioning systems sap power so switching it off lets your engine run more efficiently and at a more optimum level.
9. Switch off engine while waiting
Excessive idling can lead to wastage of burn fuel. If you have to wait in your car for more than a minute for someone, turn off the engine.
10. Tire Inflation & Repair
Under-inflated tires can greatly reduce your fuel efficiency. An under-inflated tire causes additional friction with the road, so it will consume much of the forward motion that is generated by the engine, causing the engine to work harder to propel the vehicle at the same speed.
11. Wheel Alignment
Your vehicle's wheels may be misaligned, and you might not even know it. Even a slight misalignment can cause your vehicle to drag a tire across the pavement instead of rolling properly. This causes the engine to work a lot harder and consume more fuel.
12. Avoid excessive weight in the car boot.
