7 Common Car Maintenance Myths

When it comes to maintaining your car or truck, it's easy to fall for common myths that can lead to extra costs and unnecessary work. Whether you're dealing with oil changes, tire care, or more complex repairs, understanding the truth behind these misconceptions can save you time, money, and headaches. Here are some of the most common auto body myths you should be aware of.

1. Changing the Oil Every 3,000 Miles

This was once a standard recommendation, but modern vehicles are built to last longer between oil changes. Most newer cars can go up to 7,500 miles or even more before needing an oil change. Always check your owner’s manual for the manufacturer’s recommended interval—this will ensure you’re not over-maintaining or under-protecting your engine.

2. Flush the Coolant with Every Oil Change

Many people assume that coolant should be flushed every time they change their oil, but this isn’t necessary. Coolant is designed to last much longer—typically around 60,000 miles or five years. Flushing it too often can be wasteful and costly. Keep track of your maintenance schedule and only flush when needed.

3. Always Go for Premium Fuel

If your car doesn’t require premium fuel, there’s no need to pay the extra. Most vehicles are built to run on regular gasoline (87 octane), and using a higher-octane fuel won’t improve performance unless specified in your owner’s manual. It’s a waste of money—stick to what your car actually needs.

4. Inflate Tires to the Number on the Sidewall

There’s a common mistake many drivers make: inflating tires based on the number on the sidewall. That number represents the maximum pressure the tire can handle, not the ideal pressure for your vehicle. The correct pressure is usually found on the driver’s side door jamb. Always check your tire pressure monthly and keep it at the recommended level for better fuel efficiency and safety.

5. Change All Four Tires Together

Some people believe that all four tires must be replaced at once, but this isn’t always the case. If your tires are still in good condition and have similar tread depth, you can replace them one at a time. However, if the remaining tires are significantly worn, it’s wise to replace them in pairs or all together for balanced handling and performance.

6. You Can Be Lax About the Timing Belt

The timing belt is a critical component that can cause serious engine damage if it fails. Many people ignore it until it’s too late. Most manufacturers recommend replacing the timing belt between 60,000 and 100,000 miles. Don’t wait—check it regularly and follow the service schedule to avoid expensive repairs down the road.

7. Warranties Tied to Dealer Maintenance

A common misconception is that you must get all maintenance done at the dealership to keep your warranty valid. In reality, as long as you follow the manufacturer’s guidelines and keep proper records, you can take your car to any qualified mechanic. This gives you more flexibility and potentially lower repair costs.
