Cars are part of our everyday life in Australia. Whether you’re commuting through Sydney traffic, cruising along the Great Ocean Road, or running errands in Melbourne, we all have a few “rules” in our minds about how cars work. The problem? Not all of these rules are true. In fact, some are downright misleading. Let’s debunk five common car myths that many drivers still believe — and show you the smarter way to think about your car.
Myth 1: “Premium Fuel Always Makes Your Car Run Better”
Many drivers think that if they pour premium petrol into their car, it will run smoother or get better mileage. Truth is, unless your car specifically requires premium fuel, using it doesn’t give any performance boost. Most modern cars are designed to run perfectly fine on regular unleaded petrol.
For example, a Toyota Corolla or Mazda3 bought here in Australia won’t see any difference in power or efficiency from premium fuel unless the manufacturer says otherwise. So, save your cash — you’re not buying more speed, just a pricier fuel option.
Myth 2: “You Should Warm Up Your Car Every Morning”
Some people believe that letting the engine idle for several minutes in the driveway keeps it healthy. While this was somewhat true for older vehicles, modern cars don’t need it. Today’s engines are built to perform efficiently right from the start.
Instead of wasting fuel, start driving gently. That way, the engine warms up while you’re already moving, which is actually better for its longevity.
Myth 3: “Changing Oil Frequently is Overkill”
There’s a common belief that you need to change your car’s oil every 3,000 km, or your engine will fall apart. Modern vehicles and high-quality synthetic oils have made this old rule outdated. Most newer cars can safely go 10,000–15,000 km between oil changes, depending on manufacturer recommendations.
Check your owner’s manual for the right interval. Over-oiling doesn’t hurt, but it’s unnecessary — and it can add up in costs over time.
Myth 4: “Red Cars Are More Expensive to Insure”
It’s a classic myth: red cars get pricier insurance premiums because they’re “sporty and fast.” The truth? Insurers don’t care about your car’s colour. They base premiums on factors like car model, age, engine size, and your driving history, not paint choice. So, whether you pick red, blue, or silver, your wallet won’t feel the difference.
Myth 5: “You Can Ignore Warning Lights If the Car Feels Fine”
Some drivers think that if the car seems okay, a warning light is just a minor annoyance. This is dangerous. Lights like the check engine or ABS indicator can signal issues that might get worse over time.
For instance, a minor engine sensor problem could lead to bigger repairs if ignored. If a warning light pops up, it’s better to check it immediately — a quick service visit might save you hundreds of dollars later.
Breaking the Myths Saves Money and Stress
Believing these myths can cost you more than just money. From wasted fuel and unnecessary maintenance to safety risks on the road, old misconceptions linger for too long.
Even if you’re planning to sell your car for cash, knowing the truth about car care can help you maintain its value. Cars in good condition, maintained correctly, fetch better prices. Plus, avoiding unnecessary expenses on myths leaves more money in your pocket.
The Takeaway
Cars are complicated machines, but you don’t need to fall for old wives’ tales. Modern vehicles are smarter, more efficient, and often more resilient than many myths suggest. Keep an eye on what your car really needs, and you’ll drive safer, spend less, and maybe even enjoy your car a little more.
Remember: Question the advice you hear — some myths are harmless, others can cost you big. Drive smart, and leave the myths behind.
