When most people think about fuel efficiency, they usually point fingers at things like tyre pressure, engine condition, or even driving habits. But there’s a silent culprit that often gets overlooked—your car’s suspension. Yep, that part of your vehicle that’s mainly responsible for a smooth ride also has a pretty big role to play in how much petrol you burn.
If you’re driving around Melbourne or anywhere else in Australia, dealing with potholes, uneven surfaces, or just clocking up kilometres on old suspension components, you could be spending more at the pump than you need to. Let’s break it down.
What Does the Suspension System Actually Do?
The suspension system is like the unsung hero of your vehicle. It’s a network of springs, shock absorbers, struts, linkages, and other parts that work together to keep your car stable, especially when you’re driving over bumps or around corners.
In simple terms, it’s the system that makes sure your tyres stay in contact with the road. That contact is key—not just for your comfort, but also for things like braking, handling, and yes, fuel efficiency.
So, How Can Suspension Problems Hurt Fuel Efficiency?
Let’s get into the nitty-gritty. When your suspension isn’t working properly, it doesn’t absorb shocks as well, and that creates extra resistance—meaning your engine has to work harder to move the car. And when your engine works harder, it burns more fuel.
Here’s how it happens:
- Uneven Tyre Wear = More Rolling Resistance
A dodgy suspension can mess with your wheel alignment. When your wheels aren’t aligned properly, your tyres start to wear unevenly. That not only reduces the lifespan of your tyres (ouch for the wallet), but it also increases rolling resistance.
Think of it like trying to push a shopping trolley with a wonky wheel—it takes more effort to keep it going straight. Your car feels the same way, and that effort costs you in fuel.
- Poor Road Grip = Less Efficient Driving
When your shocks or struts are worn out, your tyres don’t grip the road properly. That can cause your car to bounce more and make it harder to control, especially on rough Aussie roads.
You might find yourself accelerating or braking more than usual to compensate—both of which are terrible for fuel economy.
- Increased Drag and Body Roll
Worn suspension can also lead to more body roll when turning or going around corners. That’s extra movement your car has to correct for, which again puts more demand on the engine. It’s like running with a backpack that’s shifting around—harder, slower, and definitely more tiring.
Real-World Example: Tim from Coburg
Let’s talk about Tim. He drives a 2012 Holden Commodore and commutes daily from Coburg to the city for work. Lately, he noticed he’s filling up more often than usual, even though his driving habits haven’t changed.
He took his car in for a check-up and, surprise—his front struts were shot, and the alignment was way off. Not only was he chewing through petrol, but he was also burning through tyres faster than normal. After fixing the suspension, his fuel economy improved by about 10%. That’s a noticeable difference, especially with the way fuel prices jump around in Victoria.
How to Spot Suspension Problems Early
Suspension issues aren’t always obvious unless something’s seriously broken. But here are a few things to watch for:
- The car pulls to one side while driving
- You feel every bump in the road
- Uneven tyre wear
- The car dips or nose-dives when braking
- It takes longer to stop
- Strange noises from underneath the car
If you’re noticing any of these signs, it’s worth getting your suspension checked out—especially if your car’s getting on in years.
Why This Matters If You’re Selling or Scrapping Your Car
Now, you might be thinking: “Well, I’m planning to sell or scrap my car soon anyway. Why should I care about the suspension?”
Fair question. Here’s the deal: even if your car’s headed for the scrapyard or being sold to a cash-for-cars company like ours, suspension issues can impact the price you get.
Cars with good or salvageable parts—like a solid suspension—can fetch a bit more. On the flip side, if the whole undercarriage is wrecked or worn out, it’s just going to be valued for scrap metal weight.
So if you’re considering saying goodbye to your vehicle, knowing its condition helps you understand what kind of cash offer to expect. We see this every day when evaluating vehicles across Melbourne and beyond.
Before You Hit the Road Again…
Your suspension might not be the first thing you think about when you’re checking your car’s health. But trust us, it plays a bigger role in fuel efficiency than most people realise.
Getting it checked doesn’t always mean an expensive repair, either. Sometimes, a simple wheel alignment or replacing one worn-out component can make a world of difference—both in how your car drives and how often you need to top up the tank.
So whether you’re hanging onto your car for a bit longer or thinking about cashing it in, don’t ignore what’s going on underneath. It’s literally carrying you around, day in and day out.
What to Keep in Mind
Next time your fuel gauge drops quicker than expected, don’t just blame the traffic or the fuel price hike. Think about your suspension. A bit of attention there could save you dollars at the bowser—and keep your ride safer, smoother, and a little more wallet-friendly.
