Car maintenance: Debunking 7 common myths

Car maintenance is an essential aspect of vehicle ownership, but it often comes with a barrage of myths and misconceptions. In this guide, we aim to debunk seven common myths surrounding car care, providing clarity to help you make informed decisions and keep your vehicle running smoothly.

Myth 1: Premium Fuel Equals Better Performance

Reality: Premium fuel is not always necessary for all vehicles. Check your car’s manual; if it doesn’t require higher octane, using regular fuel won’t impact performance. Premium fuel is designed for high-performance engines that specifically demand it.

Myth 2: Engine Oil Should Be Changed Every 3,000 Miles

Reality: While this was a standard recommendation in the past, modern vehicles and synthetic oils can often go longer between oil changes. Follow your car manufacturer’s guidelines, which typically suggest intervals between 7,500 to 10,000 miles.

Myth 3: Letting Your Car Idle Warms Up the Engine Faster

Reality: Idling for extended periods is unnecessary and may even be harmful. Modern engines warm up more efficiently when driving. Prolonged idling wastes fuel, contributes to pollution, and can lead to carbon buildup in the engine.

Myth 4: Inflate Tires to the Maximum Pressure Listed on the Sidewall

Reality: The recommended tire pressure is found in your car’s manual or on a sticker inside the driver’s side door frame, not on the sidewall. Inflating beyond this recommended pressure can lead to uneven tire wear and reduced traction.

Myth 5: Wash Your Car with Dish Soap

Reality: Dish soap can strip away the protective wax on your car’s surface. Use a designated car wash soap to maintain the finish and prevent paint damage. It’s formulated to clean without compromising the protective layers.

Myth 6: Changing Only One Tire is Sufficient

Reality: For optimal performance and safety, it’s advisable to replace tires in pairs or a complete set. Mismatched tires can lead to uneven wear, affecting handling and performance, especially in vehicles with all-wheel drive.

Myth 7: You Must Return to the Dealership for Maintenance to Keep the Warranty

Reality: You have the right to choose where your car is serviced without voiding the warranty. The Magnuson-Moss Warranty Act protects consumers, allowing maintenance at independent shops as long as they follow the manufacturer’s recommended service schedule.


Car maintenance is a crucial aspect of preserving your vehicle’s longevity and performance. However, understanding the reality behind common myths is equally vital. By debunking these misconceptions, you can make informed decisions, save money, and ensure your car operates at its best. Stay informed, follow your car’s manual, and enjoy a smoother, more efficient driving experience.
