5 Vehicle Maintenance Myths You Need to Stop Believing Right Now

Writer's picture: SV EngineeringSV Engineering

When it comes to vehicle maintenance, spreading false information can lead to hefty costs and even unsafe driving conditions.


Many car owners cling to outdated beliefs that can harm their vehicles.


In this post, we will challenge five common myths about vehicle maintenance and clear the air.


So, let's get ready to uncover the truth that will keep your car in top shape.



Myth 1: You Should Always Wait for the Oil Change Light to Come On


A widespread myth suggests that waiting for your oil change warning light is sufficient to determine when to change your oil. The problem with this approach is that you may already be risking your engine's health by the time the light appears.


Regular oil changes are essential for maintaining engine health and longevity. Many manufacturers recommend changing your oil every 3,000 to 5,000 miles. For example, if you drive an older vehicle or frequently make short trips, you might want to lean toward the lower end of that range. By following this guideline, rather than relying solely on the warning light, you ensure your engine remains adequately lubricated, preventing premature wear.

Myth 2: Premium Gas is Always Better for Your Car


Another prevailing belief is that using premium gasoline will automatically improve your vehicle's performance. However, unless your car specifically requires high-octane fuel, there are usually no real benefits.


According to the American Automobile Association (AAA), 87% of vehicles on the road are designed to run on regular unleaded gasoline. Using premium fuel in these vehicles does not increase horsepower or fuel efficiency. Instead, it just leads to unnecessary spending. Always consult your owner's manual for the recommended fuel type for your car, and don't fall into the trap of overpaying for premium gas.



Myth 3: You Don’t Need to Worry About Tire Pressure in the Winter


A common misconception is that tyre pressure stabilizes in winter months. In fact, colder temperatures can decrease tyre pressure significantly, making it vital to check regularly.


For every 10°F drop in temperature, tyre pressure can drop by 1 to 2 psi. Under-inflated tyres not only impact handling but also can lead to increased fuel costs and rapid tyre wear. Experts recommend checking your tyre pressure at least once a month, especially before embarking on long winter trips. Ensuring your tyres are properly inflated can greatly improve your vehicle's performance and safety.



Myth 4: You Can Skip Fluid Changes if You Don’t See a Leak


If your car isn’t visibly leaking fluids, you might assume all is well under the bonnet... This assumption can lead to overlooking essential maintenance that can save you money in the long run.


Fluids like coolant, brake fluid, and transmission fluid should be changed at regular intervals, regardless of leaks. For instance, brake fluid should typically be replaced every 2 years or 24,000 miles to maintain braking performance.

Ignoring fluid changes can cause contamination and lead to significant repair costs later on. Regular checks and maintenance appointments can make a big difference in overall vehicle reliability.



Myth 5: A Perfectly Clean Air Filter is Always Good


While a clean air filter is crucial for your vehicle's optimal operation, some believe it should remain spotless indefinitely. This belief is misleading.


Air filters accumulate dirt and debris, which can restrict airflow to the engine over time. According to the U.S. Department of Energy, a dirty air filter can reduce engine efficiency by up to 10%. It is wise to inspect your air filter every 12,000 to 15,000 miles, or as the manufacturer recommends. Replacing a clogged filter ensures your engine runs smoothly and efficiently.



Final Thoughts


Understanding vehicle maintenance can be daunting, especially with so many myths clouding the truth. Knowing when to change your oil and what type of fuel your car requires is crucial for its longevity and performance.


By debunking these five common myths, we hope to help you to make better decisions about your vehicle's care.


Regular maintenance not only extends your vehicle's lifespan but also ensures a safer driving experience. Let go of these myths and adopt a more informed approach to car care.


Drive safe and enjoy the journey.
