Car maintenance is essential for keeping your ride running smoothly. However, many myths can lead to unnecessary expenses or even damage your vehicle. Let’s debunk some common misconceptions.

1. You need to change your oil every 3,000 miles

Once upon a time, this was the standard recommendation. Modern vehicles and synthetic oils have significantly improved. Most cars can now go 5,000 to 7,500 miles between oil changes, and some can go even longer. Always refer to your vehicle’s owner’s manual for the correct interval based on your driving habits and oil type.

2. Premium fuel improves performance in any car

Many drivers believe that using higher-octane fuel will improve their car’s performance or longevity. However, unless your vehicle specifically requires premium fuel, using regular unleaded gas is perfectly fine.

3. Warming up your car is a must before driving

Modern engines are designed to perform well without extended idling. Idling wastes fuel and increases emissions. Unless you’re operating in sub-freezing temps, it’s fine to start driving gently right after starting the engine, which helps it warm up more quickly.

4. “Tire Pressure should match the number on the tire” is a very common car maintenance myth

The pressure listed on the tire sidewall is the maximum pressure the tire can hold, not the recommended pressure for your vehicle. The correct tire pressure can usually be found on a sticker inside the driver’s door or in the owner’s manual.

5. Your car battery fully recharges after a jump start

While a jump start can get your car running, it takes several hours of driving to fully recharge a dead battery. As such, many folks who need a jump should consider a battery charger to restore the battery to full capacity, especially if it has been deeply discharged. Otherwise, it might fail again. You might also just need to buy a new battery to avoid getting stranded more than once.

6. Louder exhaust means more power

A loud exhaust can indicate an exhaust system problem, such as a leak. It doesn’t necessarily correlate with increased engine power. In fact, a properly functioning exhaust system is crucial for optimal engine performance and efficiency.

7. Washing your car in the sun is okay

Washing your car in direct sunlight can cause water spots and streaks due to rapid drying. It’s best to wash your car in the shade or during cooler parts of the day to achieve a better, spot-free finish.

8. Only check oil levels at oil change time

Regularly checking your oil level is a critical car maintenance item. It’s important to ensure there are no leaks and that your engine has enough oil to operate smoothly. Low oil levels can cause severe engine damage, so frequent checks can prevent costly repairs.

9. All coolant types are the same

Different vehicles require specific types of coolant, and using the wrong type can lead to engine damage. Always use the coolant type recommended in your vehicle’s owner’s manual.

10. Rotate tires with every oil change

Tire rotations are not optional, even if you drive carefully. Tires wear unevenly due to factors like braking and turning, so rotating them every 6,000 to 8,000 miles helps balance the wear and extend their lifespan. This might mean getting them rotated more frequently than your oil change intervals. If you have a 5,000-mile oil change interval, you can go ahead and rotate them at the same time.

By debunking these myths, you can approach car maintenance with confidence, ensuring your vehicle remains in peak condition without unnecessary or misinformed practices. You can also rely on your vehicle’s manual and trusted professionals for the best care advice.
