10 FALSE Car Maintenance Myths

car maintenance myth

As car owners, we all want to keep our vehicles in the best possible condition. Unfortunately, there are many myths about car maintenance that can lead us astray. In this blog post, we will debunk 10 common car maintenance myths and provide you with the facts you need to keep your car running smoothly.

Myth #1: You should change your oil every 3,000 miles

This myth has been around for decades, but it’s simply not true anymore. Modern engines and oils have improved dramatically over the years, and most manufacturers now recommend changing your oil every 7,500 to 10,000 miles. In fact, some newer cars are equipped with oil life monitoring systems that will tell you when it’s time for an oil change based on your driving habits and other factors.

Myth #2: Premium fuel is better for your car

If your car requires premium fuel, then you should definitely use it. However, if your car is designed to run on regular unleaded fuel, there is no benefit to using premium fuel. In fact, using premium fuel when it’s not required can actually harm your engine and decrease fuel efficiency.

Myth #3: You need to warm up your car before driving

This myth was true back when cars had carbureted engines, but it’s not necessary with modern fuel-injected engines. In fact, idling your car for more than 30 seconds is just wasting gas and putting unnecessary wear on your engine. Simply start your car and drive gently until it reaches operating temperature.

Myth #4: You should always use the dealership for maintenance

While dealerships are a great option for certain types of repairs and maintenance, they are not always the best choice. Independent mechanics and specialty shops often offer lower prices and can provide personalized service. Just make sure to do your research and choose a reputable mechanic.

Myth #5: You need to replace both tires at the same time

If one of your tires is damaged or worn out, you don’t necessarily need to replace both tires. However, you should make sure that the new tire matches the existing tire in terms of brand, size, and tread pattern. If your tires are worn out, it’s a good idea to replace all four tires at once to ensure even wear and optimal performance.

Myth #6: You should change your air filter every year

While it’s important to replace your air filter on a regular basis, there is no set time frame for doing so. How often you need to replace your air filter will depend on your driving conditions and the type of air filter you have. Some filters are washable and can be reused, while others need to be replaced every 15,000 to 30,000 miles.

Myth #7: You should always change your transmission fluid at 50,000 miles

While this used to be true, many car manufacturers now recommend changing your transmission fluid at longer intervals or not at all. In fact, some newer cars have sealed transmissions that don’t require fluid changes. Check your owner’s manual for the recommended service interval for your specific vehicle.

Myth #8: You should replace your brake pads every 20,000 miles

This myth is simply not true. How often you need to replace your brake pads will depend on your driving style and the type of pads you have. Some pads can last up to 70,000 miles, while others may need to be replaced after only 20,000 miles. A reputable mechanic can inspect your brakes and let you know when it’s time for new pads.

Myth #9: You should always warm up your engine in cold weather

While it’s true that your engine needs to reach operating temperature before you start driving, idling your car for more than 30 seconds is just wasting fuel and putting unnecessary wear on your engine. In cold weather, it’s best to start your car and drive gently until the engine warms up. This will allow the engine to warm up more quickly and efficiently.

Myth #10: You should use dish soap to wash your car

While dish soap may seem like a cost-effective way to wash your car, it can actually do more harm than good. Dish soap is designed to remove grease and grime, which can strip the protective wax from your car’s paint. Instead, use a car-specific soap that is designed to clean your car without damaging the paint or protective coating.


As you can see, there are many car maintenance myths that can lead us astray. By understanding the facts behind these myths, we can make informed decisions about how to care for our cars. Whether it’s changing your oil, replacing your tires, or washing your car, it’s important to follow the manufacturer’s recommendations and seek the advice of a reputable mechanic when necessary. By doing so, you can help ensure that your car stays in great condition for years to come.
