Common Car Repair Misconceptions And How To Avoid Them

Car maintenance and repairs can be a daunting task for many car owners. With so much information on the internet, it’s not always easy to separate facts from myths. Unfortunately, some of the most common misconceptions about car repairs can lead to unnecessary expenses and even damage to your vehicle.

Knowing the misconceptions can help you save money, prolong the life of your vehicle, and ensure that your car runs safely and efficiently. Let’s jump right into it!

Misconception 1: Changing oil every 3,000 miles

Changing oil every 3,000 miles is not necessary for most modern cars. Advances in engine technology and oil formulations have led to longer intervals between oil changes for many vehicles.

By changing your oil too frequently, you not only waste money but also potentially shorten the life of your engine. It’s important to note that some cars may require more frequent oil changes, such as those used for heavy-duty or severe driving conditions and older cars, but this is not the case for most modern cars. The key is to follow the automotive repair’s guidelines for oil changes, which can be found in your owner’s manual or by checking the vehicle’s information system.

Misconception 2: Premium gasoline is always better

Premium gasoline is always better is a misconception because the octane rating of gasoline refers to its ability to resist “knocking” or “pinging” during combustion, caused by the air/fuel mixture detonating prematurely in the engine. High-performance and luxury vehicles may require premium gasoline with a higher octane rating. Using premium gasoline when not required can be a waste of money and does not provide any added benefits for most vehicles on the road.

The solution for this is to check your vehicle’s owner’s manual or consult with the dealership to see what type of gasoline is recommended for your car. If the manual or dealership says that regular gasoline is sufficient for your car, you can safely use it and save on fuel costs. If premium gasoline is recommended, then you should use it to ensure the optimal performance of your vehicle.

Misconception 3: Replacing car battery every three years

Replacing a car battery every three years is a misconception because the life of a car battery depends on several factors, such as usage, temperature, and the type of battery. Many batteries today can last for 4 to 5 years or even longer with proper care and maintenance. Using a new battery when the old one is still functional is not only an unnecessary expense but also an environmental waste.

The solution for this is to check the status of your battery regularly. You can do this by using a voltmeter or taking it to a mechanic for a check-up. If the battery is holding a steady charge, it is still good. It is also vital to keep the battery clean and tight and avoid leaving your lights on or other electrical devices running while the car is turned off.

Misconception 4: Warming up the car before driving

Warming up the car before driving is a misconception because modern cars have electronic fuel injection and computer-controlled engines which don’t require warm-up time. In the past, cars had carburettors and required a warm-up period to ensure proper lubrication and to bring the engine to its optimal operating temperature, but this is not the case anymore. Idling your car for long periods can harm your engine and waste fuel.

The solution for this is to start driving your car as soon as you start the engine. This will allow the engine oil to circulate and lubricate the engine components quickly. It’s also important to note that if the temperature is extremely low, you should let the engine idle for a few minutes to allow the oil to circulate before you start driving. It’s also important to note that if you live in a colder climate, it’s better to invest in an engine block heater which allows the engine to warm up faster and use less fuel in the process.

Misconception 5: Driving with a “check engine” light on

Driving with a “check engine” light on is a misconception because not all check engine lights are created equal. Some issues that trigger the light are minor and can be safely driven, while others can cause serious damage if not addressed promptly. The “check engine” light indicates a variety of problems, from a loose gas cap to a serious engine or emissions issue. Ignoring the light or driving with it on for a long period of time can cause more serious problems and costly repairs.

The solution for this is to have the vehicle scanned for diagnostic trouble codes as soon as possible when the check engine light is on. This can be done by a mechanic or by using an OBDII scanner which can be purchased or borrowed from an auto-parts store. This will give a code that can indicate the problem and its severity. If the problem is minor and does not affect the drivability or safety of the vehicle, it can be addressed at a later time. But if the problem is serious, it should be fixed immediately to avoid further damage. It’s also important to note that if other warning lights or strange noises accompany the check engine light, it’s best to have your car checked by an automotive repair near me as soon as possible.
