6 Car Maintenance Myths That Cost You Money (and What’s Actually True)

Keeping your car in top shape doesn’t have to be confusing, but with so much advice online, it’s easy to believe a few common myths that could cost you time, money, or even safety. Let’s clear up some of the biggest misconceptions about car care, and look at how modern drivers can stay on top of maintenance, without stress.

Myth 1: Oil Needs Changing Every 3,000 Miles

This one is classic, but outdated.

Modern synthetic oils are designed to last much longer than the old standard of 3,000 miles. Manufacturers often recommend 7,500 to 10,000 miles between oil changes, depending on driving style, climate, and vehicle type.

Why it matters: Oil lubricates and protects your engine. Over time, contamination, metal particles, or wear can build up. If a technician spots these signs, delaying a change can lead to bigger problems.

Tip: Always follow the manufacturer’s service schedule, but trust your technician if they recommend an earlier change.

Myth 2: Premium Fuel Always Improves Performance

Premium fuel is often marketed as a performance booster, but for most cars, regular fuel is perfectly fine. Spending extra money on premium won’t necessarily make your engine run better or last longer unless your vehicle specifically requires it.

What matters more: Timely maintenance, clean filters, spark plug replacements, and regular checks of key systems. These are the real ways to protect engine health.

Myth 3: Warming Up Your Car Takes 10 Minutes

Many drivers still believe that letting the car idle for 10 minutes before driving is necessary. Modern engines warm up fastest when driven gently, even in cold weather. Idling wastes fuel, creates extra emissions, and doesn’t protect the engine any more than driving carefully does.

Tip: Start the car, wait 30–60 seconds for oil circulation, then drive off gently. Avoid hard acceleration until the engine reaches operating temperature.

Myth 4: You Must Replace All Tyres Together

While matching tyres on an axle is essential for safety, you don’t always need to replace all four tyres at the same time. Sometimes, just two new tyres on the same axle are enough.

What matters: Tyre condition, tread depth, and matching tyre types. Uneven tyres can affect handling and ABS performance, so always check with a technician.

Helpful note: When new tyres are needed, flexible payment options like Bumper can make the replacement easier to approve, so you can stay safe without financial stress.

Myth 5: Brake Fluid Never Needs Changing

Brake fluid might seem “out of sight, out of mind,” but it absorbs moisture over time. Old or contaminated brake fluid can reduce braking efficiency and potentially lead to costly repairs.

Tip: Most manufacturers recommend changing brake fluid every 2 years, even if the brakes feel fine.

Myth 6: EVs Need No Maintenance

Electric vehicles have fewer moving parts, but they’re not maintenance-free. EVs still need:

• Brake inspections and replacements

• Tyre rotations and replacements

• Battery and charging system checks

• Suspension and steering maintenance

Final Thoughts

Car maintenance doesn’t have to be confusing or stressful. By busting these common myths and understanding what your car really needs, you can keep it running safely and efficiently, and make sure that unexpected costs don’t get in the way.
