When it comes to car maintenance and repairs, everyone seems to have an opinion. Friends, relatives, and even roadside mechanics share advice — but not all of it is true. In fact, many of the things people believe about car repair are myths that can cost you money, reduce your car’s life, and even compromise your safety.

In this article, we uncover the top 15 car repair myths you should stop believing right now.

1. “Premium fuel will improve my car’s performance.”

Unless your car is specifically designed for high-octane fuel, premium petrol will not make it run better or faster. Regular cars do perfectly fine on regular fuel. Premium fuel only benefits engines that require it.

2. “You must change your engine oil every 3,000 km.”

Modern engines and high-quality synthetic oils last much longer. Most cars only need an oil change every 8,000–10,000 km (or as per manufacturer instructions). Changing too frequently is just unnecessary expense.

3. “Air conditioning reduces fuel efficiency drastically.”

Yes, AC does use some fuel — but not as much as people think. In many cases, especially at highway speeds, driving with open windows creates more drag and reduces mileage even more.

4. “Washing the car with dish soap is safe.”

Dish soap strips away wax and protective coatings, making your paint fade faster. Always use a car-specific shampoo.

5. “If it’s not broken, don’t fix it.”

Preventive maintenance is cheaper than major repairs. Ignoring small issues like vibrations, noises, or fluid leaks can lead to costly breakdowns later.

6. “You only need to replace a tyre when it bursts.”

Wrong. Tyres should be replaced when:

• Tread depth is too low

• Sidewalls have cracks

• The tyre is older than 5 years

Driving on worn-out tyres is extremely dangerous.

7. “Battery failure happens without warning.”

Batteries usually show signs:

• Slow engine cranking

• Dim headlights

• Electrical issues

• Dashboard battery warning

Ignoring these signals can leave you stranded.

8. “Brake pads last for years, no matter how you drive.”

Brake pads wear out faster in:

• City traffic

• Hilly areas

• Aggressive braking

• Heavy-loaded cars

You should inspect them regularly instead of assuming they’ll last.

9. “A bigger car needs more servicing.”

Service frequency depends on:

• Engine type

• Driving conditions

• Manufacturer recommendations

Size has nothing to do with maintenance intervals.

10. “Idling the engine warms up the car faster.”

Modern engines warm up quicker when driving, not idling. Long idling only wastes fuel and harms the environment.

11. “All car mechanics overcharge.”

Not all mechanics are the same. Certified workshops, digital service platforms, and transparent billing have made repairs more honest and affordable.

12. “A car with new parts is always better.”

Not necessarily. Sometimes refurbished or OEM-equivalent parts perform just as well as new ones — at a lower cost. The key is quality, not just “brand new”.

13. “Engine overheating only happens in summer.”

Overheating can occur:

• Due to coolant leaks

• Faulty thermostat

• Bad radiator fan

• Low coolant

• Blocked radiator

It can happen any time of the year.

14. “Wheel alignment is only needed when the car pulls to one side.”

Even if your car drives straight, alignment might be off. Misalignment causes:

• Uneven tyre wear

• Poor fuel economy

• Steering issues

You should check alignment every 6 months.

15. “Car service at authorized centers is always better.”

Authorized service centers are not the only reliable option. Many independent garages and multi-brand workshops offer:

• Lower costs

• Faster service

• Genuine spare parts

• Skilled technicians

It’s about expertise, not just the brand.

Conclusion

Car repair myths can lead to poor decisions, unnecessary expenses, and even breakdowns. Understanding what’s true — and what’s not — helps you maintain your vehicle efficiently, save money, and drive safely. To keep your car in top condition, always follow Drivlu.
