Car maintenance is often surrounded by myths and confusing advice—from how frequently you should change the oil to tips for preserving your paint. This guide debunks common misconceptions and reveals the true secrets to keeping your vehicle in optimal condition, saving you time, money, and avoiding major breakdowns.

Your car isn’t just transportation—it’s an investment and daily companion. Keeping it well maintained ensures road safety, extends lifespan, and helps avoid costly repairs. Preventative care—like oil changes, brake inspections, tire pressure checks, and electrical system reviews—is key to keeping your vehicle performing for years to come.

1. The 5,000 km Oil Change Myth: Do You Really Need Such Frequent Changes?

For decades, drivers followed the rule of changing oil every 5,000 km. But today’s engines and oils are more advanced. Most manufacturers now recommend much longer intervals—often between 10,000 and 15,000 km, or even more, depending on the model and the oil type (conventional, synthetic, or semi-synthetic). The best advice is always to check your vehicle’s manual for the specific recommendation.

2. Beyond Washing: Secrets to Keeping Paint Like New

A clean car isn’t just good-looking—well-maintained paint protects from rust. Regular washing is crucial, but so is using pH-neutral soaps and avoiding sunlight during cleaning. For a professional finish, consider adding wax or sealant. Besides shine, these products create a protective layer against environmental contaminants.

3. Tires on the Ground: The Overlooked Importance of Tire Pressure

Tire pressure is essential for safety and efficiency. Incorrect pressure impacts road stability, increases fuel consumption, and speeds up tire wear. Check tire pressure monthly and before long trips. Find the recommended level on a sticker inside the driver’s door or in the car manual.

4. The Purring Engine: Simple Habits to Prevent Big Issues

Your engine is your car’s heart. Maintenance doesn’t require advanced skills—just check fluid levels like coolant and brake fluid regularly. Pay attention to unusual noises or vibrations. Ignoring small squeaks can lead to big, expensive repairs. Preventive care is the best way to ensure engine longevity.

5. Longevity Key: Keeping the Air Filter Clean

A dirty air filter is like breathing through a dusty cloth—your engine works harder, lowering fuel efficiency and power. Check and replace the air filter as needed to keep airflow optimal.

6. Fuel Myths: Is Premium Always Better?

Many believe “premium” gasoline is best for their car, even if the maker doesn’t require it. Truth: higher octane is only needed for high-performance engines designed for it. Using premium when it’s not required wastes money and won’t improve engine life or performance.

7. Brake System Maintenance: More Than Just Changing Pads

Your brakes are vital for safety, but maintenance goes beyond pad changes. Always check discs and brake fluid levels. A soft or “sinking” pedal may signal a more serious issue. Don’t ignore warning signs.
