You've recently earned your licence and have purchased or are about to buy your first car. At this point, you should have figured out how much you need to budget every month for car-related expenses.

Most of these costs, such as season parking, monthly payments and road tax, are fixed. But if there's one thing you can reduce, it would be your petrol costs. The key to this is bettering your fuel economy.

It may seem trivial to improve your consumption from 13km/L to 15km/L. But that extra 2km/L means that for every 40 litres, you would be covering an extra 80 kilometres!

Here are some useful tips that they may not have taught you at driving school.

1. A light touch

You've probably learned that shifting up early helps reduce fuel consumption by keeping the engine speed (revolutions per minute) lower.

Another technique you should practice is using a light touch on the accelerator. Do this by imagining there's an egg between your foot and the accelerator pedal.

The goal is to press the accelerator without 'cracking the egg'. Sure, the car won't pick up speed as quickly, but with a light touch, you'll enhance your efficiency and even provide a smoother ride.

2. Use 'Eco' mode

Many modern cars today offer a variety of driving modes for the driver to choose from. These typically consist of 'Normal', 'Sport' and 'Eco'.

If your car has a drive mode switch or button, try cycling through the modes till you see 'Eco'.

Along with using a light touch, activating Eco mode tells the car to reduce the engine's responsiveness and instructs the gearbox to shift up earlier as well.

In some models, the air-con compressor's power will also be reduced, lowering the power drain on the engine and thereby helping improve fuel economy.

3. Activate the stop-start function

Along with using Eco mode, another way to save fuel is by activating your car's stop-start feature.

As its name suggests, the function turns the engine off when conditions are ideal, such as when you're stopped and otherwise idling at a red light, thereby saving petrol.

Many motorists dislike this feature since it turns off the air-con and makes everyone feel warm. But if you're keen to reduce your fuel expenses, you should keep it switched on.

If you're not convinced, try utilising it for a month before checking the trip computer. Most cars with stop-start have a menu that displays how much fuel you've saved with this feature.

4. Choose the right fuel

Perhaps friends or relatives have told you that 98 RON or premium fuel like V-Power is best for your car. But a higher RON doesn't always mean it's better.

The higher the RON (research octane number), the more resistant a petrol is to premature combustion, which causes knocking or pinging.

However, unless you're driving a high-performance or sports car, stick with 95 RON, which is adequate for most car models. Honestly, a regular runabout is unlikely to require 98 RON. 
 
If in doubt, check your owner's manual. There's nothing wrong with 98 RON or even premium petrol, as filling up with it won't damage your engine. But if your car does not require it, you'll end up spending more without enjoying any discernible benefits.

5. Journey planning

Navigation apps like Waze or Google Maps are helpful in guiding you to your destination. Journey planning, on the other hand, is seeing the bigger picture by scheduling and figuring out who needs to go where and when.

If you live in the east or west and need to head in the other direction for work or to meet up with friends, run any errands you need to run there when you're heading there, instead of returning again another day.

It may seem troublesome at first to have to discuss logistics, but better fuel economy is definitely worth the effort.

6. Waze is useful

After you've planned your journey, using an app like Waze to navigate there - even if you know the way - is still useful.

That's because the data is crowdsourced. Based on users' traffic reports, Waze can recommend a quicker route. And sometimes, the route isn't always the shortest, but the one with the least congestion.

Waze also lets drivers report traffic jams, road works, accidents and yes, even police presence. So, keeping it running can certainly be a time and fuel-saver!

7. Timely servicing

A car engine requires timely servicing. For most Japanese and Korean makes, a service interval is either every six months of 10,000km, whichever comes first.

Maintaining your car's condition goes a long way towards ensuring lower or at least optimal fuel economy. Apart from replacing the engine oil and oil filter, mechanics will also replace any other required fluids, inspect the drive belts, and etc.

Never believe anyone who tells you that 'cars are reliable and don't need servicing'. That person won't be there to help you when your car inevitably breaks down!

8. Check your tyre pressures

Correctly inflated tyres improve fuel economy by reducing rolling resistance and helping provide optimal grip. Lower rolling resistance means the engine exerts less effort to turn the wheels, thereby reducing fuel consumption.

Check your tyre pressures at least once a month, and do it when they're still cold. If you have to top-up air, do it at the nearest petrol kiosk so the tyres don't get too warm and the air inside doesn't expand too much.

To determine the correct pressure, check the label located on the door sill on the driver's side. It will state the correct pressures that the tyres should be inflated to.
