KEEP IT SHUT
A car’s fuel efficiency has a lot to do with how it parts air on the move. In other words, aerodynamics.

Open windows, even partly, at high speeds can impact fuel efficiency and result in the tank draining out quicker due to increased drag.

Contrary to popular notion, you’ll save more fuel with the windows up and the air conditioner turned on.

2. ALL GEARED UP
Shift to the highest possible gear without the engine knocking.

A car consumes more fuel in lower gears when accelerating. If the engine’s not pulling, shift down instead of pressing the throttle.

Shifting up at 2,000 rpm (1,500 rpm for diesel) gives the best mix of speed and economy. On an automatic with manual shift, short shift to save fuel.

3. LOSE SOME WEIGHT
The heavier the car, the greater will be its thirst.

You don’t have to be a quantum physicist to know this.

So ditch that child safety seat you don’t use anymore, the spare tyre that’s not fit for use or even the tonnes of garbage that you lug around.

Keep the boot empty and clean and watch the fuel gauge become more stable. The extra bucks will make up for the trouble.

4. IDLING IS THE DEVIL’S WORKSHOP
An idling car burns fuel without really going anywhere.

So if you have your engine running while you’re waiting for someone, you’re effectively getting 0 kmpl at that time.

 

Some cars even give a litre per hour consumption on their trip computers to help you keep track. Simple solution. Switch the engine off. Or, if you have the budget, buy a car with auto start-stop technology.

5. KEEP IT CLEAN
Don’t drive your car with dirty or clogged filters, such as the air filter or the oil filter if you don’t want to shell out at the pump. Get them cleaned or replace them.

It will be money well spent since you won’t be bleeding slowly. A serviced engine will also consume less fuel, so don’t ignore the schedule.
