Use the Air Conditioner sparingly
Do not use the air conditioner unless you really need it as air conditioner utilizes extra fuel when operating. Be smart when using the air conditioner. On the highway, turn on the air conditioner and wind up all the windows, as closed windows will decrease air resistance. However, at low speeds and in stop and go traffic, it costs less to drive with air conditioner turned off and windows wind down.

Drive slow and steady
Reduce your speed and drive slowly. The faster you drive, the more wind resistance your vehicle will face and the more fuel you use. For instance, driving at 55mph rather than 65mph can improve fuel economy.

Avoid frequent acceleration and sudden stops. Repeated acceleration and hard brakes can lower your fuel mileage. Anticipate merging traffic and traffic lights in order to accelerate and decelerate smoothly.

Use the correct gear position
When stopping for a length of time or at traffic lights, put your gear into neutral or park position. This can save fuel. Incorrect gear shifting can lead to increase in fuel consumption.

Clutch and Accelerator control
Do not manipulate the clutch and accelerator to stay stationary as it wastes fuel. Riding the clutch causes loss of energy and damages to the clutch. Use handbrake when stopped on an uphill.

Check and clean your air filter
Air filters prevent dust from fouling the engine and keep impurities from damaging the inside of the engine. Check your air filters periodically to make sure it is clean and not clogged. Replacing a clogged air filter can improve your car's fuel consumption.

Get your car tuned up
Tuning up your car may cost you a little more but in the long run, you will save money by improving your fuel mileage. Make sure your engine is in proper mechanical condition and follow through with routine maintenance. Get it checked if you sense any unusual sound, smell or vibration. A poorly managed engine increases fuel consumption.

Use the right oil
Check the car manual and the manufacturer's recommendation on which grade of oil to use. Engine oil that is thicker than the recommended oil can cause increase in fuel consumption.

Stop engine when you stop your car
Turn off the engine when you stop your car and do not leave it idle for a long period of time. Keep the battery, dynamo, self-starter and fan belt in good condition to ensure a quick start.

Reduce loads
Remove unneeded items from your car and get rid of unnecessary weight as much as possible. The heavier the load your car has to carry, the more fuel it consumes.

Car Pool
Car pool whenever possible and look for people who go to the same direction as you so that you can share the costs. For instance, you can ask a neighbour with children in the same school as your children to take turns picking them up from school.

Do not overfill fuel tank
When filling fuel tank, stop at the first click of the nozzle. Too much fuel will be spilled and wasted through evaporation. After filling the fuel tank, tighten the fuel cap and if it doesn't fit snugly, get a new one. Fuel can evaporate easily from the fuel tank if it is not well sealed.

Don't drive
Avoid driving and take alternative ways such as cycling, walking or use the public transportation where feasible.

Keep tyres in good condition
Keep the tyres inflated properly and check them frequently. You will get better mileage by keeping tyres inflated to the correct pressure. Under inflated tyres increase rolling resistance that leads to higher fuel consumption. Make sure you check the tyres regularly for alignment and balancing.

Plan your route
Rush hour or stop and go traffic can waste fuel. Plan your stops for the most efficient route and take a less congested route whenever possible as highly congested road can waste fuel excessively.

When travelling, get a map of that area to avoid getting lost which will increase your fuel consumption.
