Understanding Fuel Consumption: What You Need to Know

15 July 2024

Did you know that over half of Australian households own at least two cars? With so many vehicles on the road, it's crucial to understand fuel consumption and fuel-efficient vehicles.

But why is maximizing fuel efficiency important, and why should drivers care? If you're interested in fuel tracking, we're here to help.

Let's dive into a comprehensive fuel consumption guide and explore why this information matters. We'll also look at how to calculate fuel consumption and what factors affect efficiency.

What Is Fuel Consumption?

Simply put, fuel consumption is how much fuel your car uses. While there's more to it, this is a key starting point.

Fuel consumption measures your vehicle's fuel efficiency. A car with high fuel consumption uses more petrol than one that's more efficient.

Calculating Fuel Consumption

Figuring out basic fuel consumption is easy. Just measure how far your car goes on a set amount of petrol.

Here's a simple way: Fill your tank completely. Reset your odometer, which tracks your car's distance. When you need to refill, you can work out how many kilometers you drove compared to how much petrol you used.

For example, if a car travels fifty kilometers on five liters of petrol, its fuel economy is 10 kilometers per liter.

Many factors can affect your fuel consumption. Use this simple calculation as a starting point. Another common method is to measure fuel efficiency in liters-per-100-km.

Economic Impact

Your car's efficiency is closely linked to its economy. That's why many people call fuel efficiency "fuel economy."

Basically, the more petrol your car uses, the more often you need to fill up. Your car's tank size also plays a role.

So, a car with poor fuel consumption usually costs more to run than one with good fuel efficiency. That's why many people prefer cars with better average fuel consumption. Their fuel lasts longer, goes further, and they spend less on petrol each month.

Environmental Concerns

Many people also care about how cars with poor fuel efficiency impact the environment. Studies show about two-thirds of Australians worry about climate change affecting the planet's health.

Cars that use more fuel tend to produce more emissions. This is partly because they pollute more by using petrol faster. They also need to fill up more often, which keeps adding to climate change.

More fuel-efficient cars cause less pollution over time, though they still produce significant carbon emissions. Consider ways to maximize fuel efficiency to help reduce your car's environmental impact.

Factors Affecting Fuel Consumption

Now that we understand fuel consumption better, what affects your car's efficiency? If you're interested in fuel tracking, it's important to know what impacts your car's performance. Here are the main things to consider when working out your car's fuel consumption.

Vehicle Size

Your car's size is another important factor. To be clear, a bigger car won't always have worse fuel economy than a smaller one. Other factors, like age, can change this.

However, larger vehicles need more power to move, which naturally uses more fuel. So, bigger vehicles often use more fuel than smaller ones.

These vehicles also often have larger tanks to hold more fuel. Having a bigger tank can mean you don't have to fill up as often.

Vehicle Age

As cars have evolved, makers have found ways to maximize fuel efficiency. Newer cars often have better efficiency than the same make and model from ten years ago, for example.

If the car has been driven a lot, it might also be less efficient. As your engine gets older and wears down, it can become less efficient.

It's important to research which cars have the best fuel efficiency. The Australian Bureau of Statistics has seen little change in overall car fuel efficiency since 1963. This is mainly because buyers often prefer larger, less efficient cars, not because more efficient cars aren't available.

Engine Care

Finally, since engine wear and tear is a big factor, taking care of your engine can improve your fuel efficiency.

If your engine is poorly maintained, it will consume more fuel. Regular servicing can help keep your engine in good shape and improve fuel efficiency.

Boosting Fuel Economy

Does this mean you need a small, new car for better fuel economy? Not at all. There are many ways to make your current vehicle more efficient. Here are three top tips:

Drive Smart

Your driving habits greatly affect your car's fuel use. Smooth driving can make a big difference.

For instance, quick acceleration uses more fuel. Instead, speed up gradually. This works well on highways or quiet roads with few stops.

Also, try to avoid frequent stops and starts. Sudden braking and repeated acceleration increase fuel consumption.

Look After Your Vehicle

Engine care is important, but there's more to vehicle maintenance.

Keep your whole car in good shape. Worn-out tires can increase road friction, using more fuel. Even dents in your car's body can affect its aerodynamics and fuel use.

Consider an Upgrade

If possible and within your budget, a different vehicle might improve your fuel efficiency. Research to find a car that suits your needs.

Hybrid or electric vehicles are worth considering. Hybrids use both electricity and gas, while electric cars run solely on electricity, eliminating gas use completely.

Common Fuel Efficiency Myths

When researching fuel efficiency, you might come across some myths. Let's clear up some common misconceptions:

Manual Cars Always Use Less Fuel

While manual cars often have better fuel efficiency, it's not always true.

Factors like vehicle weight, driving style, and traffic conditions can make manual cars less efficient. In fact, automatic transmissions are often more fuel-efficient now.

Premium Fuel Is Always Best

At the gas station, you'll see different fuel options. You might think premium fuel is always better for efficiency.

However, cars are designed for specific fuel types. Using premium fuel in a car made for regular gas won't improve efficiency and could even harm the engine.

Idling Saves Fuel

Some people think leaving the engine running uses less fuel than turning it off and on again, like when parked or in a drive-thru.

The truth depends on how long you're stopped. For stops under a minute, idling uses less fuel. For longer stops, turning off the engine saves more fuel.
