Are you a new car owner, and everyone is giving you advice on how to keep your car in good condition? Or did you hear a ridiculous tip, and you are thinking: “No way, this can’t be true!”.

As car insurance professionals, we know a thing or two about cars, and most of the car maintenance myths are for marketing propaganda. 

We have taken it upon ourselves to debunk some of the most popular car myths. 

Myth 1: Warm Your Car For A Few Minutes Before Driving

The Truth: This would make sense if you were driving a 1988 Toyota Camry. Modern engines are ready to go the moment you turn on the ignition. The longer your drive, the faster you warm up the engine, and the quicker it reaches optimum state for fuel economy and the car’s performance. 

Myth 2: Change Your Engine Oil After 3,000 Miles

The Truth: Engine oil manufacturers use this tactic to get motorists to buy engine oils often. Like decades ago, this was true to keep your cars in top-notch condition. But, in recent times, with the innovative engines, and better engine compositions, most cars can drive as much as 7500 miles before requiring an oil change. But don’t take our word for it; read your owner’s manual to know how to schedule your oil change. 

Myth 3: Premium Fuel Is Better for Your Car 

The Truth: The regular fuel most people buy is the standard for any car. The premium petrol everyone is touting you should use instead is best suited for high-compression and combustion engines, which are usually inexpensive cars, too. Regular grade (95-octane fuel) works just fine for your car.

Myth 4: If One Tire Is Damaged, You’d Have to Replace All Four. 

The Truth: Even if you were a billionaire, you’d be throwing money away unnecessarily if you do this. The other three tires are still worth good money as used ones. As long as you are getting a new tire that is the same as your old tires, you are okay. 

Sometimes, you might not need to replace your tires. If the puncture is on the sidewall or is larger than a quarter inch in diameter, you can get the hole plugged in by a mechanic. 

Myth 5: Inflate Your Tires to The Amount of Pressure Embossed on The Tire

The Truth: This might seem like common sense to inflate your tires to the pressure stated on the tires. Well, note that that is the maximum amount of pressure you should inflate your car tires. It is not invariably the ideal pressure. Check for the recommended pressure for your tires on a sticker put on the driver’s door jamb or the inside of the little fuel door. Inflating your tires to maximum pressure might wear them out, and you might need to replace them quickly. 

Myth 6: You Can Use Dishwasher Soap to Wash Your Car, Don’t Use Laundry Soap 

The Truth: Any soap that is not for washing your car will gradually damage your car’s exterior — chipping off the paint and exposing it to rust. Buy a car wash liquid; they are made specifically for washing cars and will help your car shine look better for longer. 

Myth 7: Change Your Transmission Fluid After Every 50,000 miles 

The Truth: As with our other myths, this one would have been a fact some years back, but they have engineered modern engines to use these transmission fluids for the car’s lifespan or 100,000 miles. It differs from car to car. Be sure to check the manufacturer’s recommendations on when to flush your transmission fluid.  

Myth 8: Buy Your Fuel in The Morning Because You Get More Value for Your Money. 

The Truth: Yes, gasoline expands with heat, so the common notion is that buying it in the morning when it is cooler is better than buying it by noon because then you get less fuel. 

They store petrol underground; they maintain and insulate it at certain temperatures. Regardless of what time you’re getting it, you receive the volume of what you pay.

Myth 9: Servicing Your Vehicles at Independent Repair Shops Will Void Your Warranty 

The Truth: It is illegal for the dealership you purchased your vehicle to mandate you to come to them only for maintenance. Your warranty remains valid until the day of expiration. When you have to claim your warranty, take along receipts that show what maintenance you have carried out on your car and how much they cost. As long as they do maintenance according to the manufacturer’s requirement, your warranty should not be voided.

Myth 10: Roll Down Your Windows to Save Fuel Instead of Using the AC to Save Fuel 

The Truth: In reality, using air conditioning consumes a tad more fuel, but even when you roll your windows down, it pushes against the wind increasing resistance, causing your car to burn more petrol to compensate for the drag. There is no economic advantage using the air conditioner compared to having your windows down. 

Conclusion

As you can see, many of these myths were quite useful back in the day, practically useless in this era of technological advancement. Some business manufacturers will continue to tout some unfounded studies and facts so that you’ll keep spending more. If you are not sure about something, use your owner’s manual or ask your local mechanic.
