Top 10 Car Maintenance Myths Debunked

Welcome to Nelson Auto Repair’s blog, your trusted source for expert auto care advice in Naperville. As Naperville’s #1 auto repair company, we’re here to set the record straight on some of the most common car maintenance myths. Let’s dive into the top ten misconceptions and reveal the truth to keep your vehicle running smoothly.

Myth 1: Engine Oil Should Always Be Changed Every 3,000 Miles

One of the most persistent myths in auto care is the need for an oil change every 3,000 miles. Modern lubricants and engine technology have evolved, allowing many vehicles to go 5,000 to 7,500 miles or more between oil changes. Always refer to your vehicle’s owner’s manual for the manufacturer’s recommendations.

Myth 2: Premium Fuel Boosts Performance in All Cars

Many believe that filling up with premium gas improves car performance and efficiency, regardless of the vehicle. However, unless your car is specifically designed for high-octane fuel, using premium gas won’t enhance performance and will only drain your wallet faster.

Myth 3: You Can Ignore the Check Engine Light If the Car Seems Fine

Ignoring the check engine light can lead to major issues down the line, even if the car appears to be running smoothly. This light is an early warning system that something might be amiss with your vehicle. Always get it checked to prevent potential costly repairs.

Myth 4: Washing Your Car with Dish Soap is Okay

Dish soap can strip away the protective wax coating on your car, leading to paint damage over time. Always use automotive soap, which is formulated to clean without removing the wax layer.

Myth 5: Inflate Tires to the Pressure Shown on the Tire Sidewall

The number on the tire sidewall is the maximum pressure the tire can hold, not the recommended level. For optimal performance and safety, inflate your tires to the manufacturer’s suggested PSI, usually found on a sticker inside the driver’s door.

Myth 6: A Coolant Flush is Only Necessary When Your Antifreeze Changes Color

Coolant degrades over time and loses its ability to protect your engine from extreme temperatures. Regular coolant flushes are crucial, even if the antifreeze looks fine, to prevent overheating and corrosion.

Myth 7: If Your Brake Fluid is Low, Just Top It Off

Low brake fluid can indicate a leak or that your brake pads are wearing down. Simply topping off the fluid can mask a potentially serious issue. If you notice low brake fluid, have your brakes inspected to ensure your safety.

Myth 8: Your Battery Doesn’t Need Maintenance

Car batteries require regular checks and cleanings to ensure proper connections and prevent power issues. Corrosion on the terminals can lead to starting problems and reduce the battery’s lifespan.

Myth 9: All Maintenance Should Be Done at the Dealership

While dealerships are a reliable source for maintenance, reputable independent auto repair shops like Nelson Auto Repair offer high-quality service that meets or exceeds dealership standards, often at a more affordable price.

Myth 10: Your Car’s Maintenance Doesn’t Affect Its Resale Value

Regular maintenance significantly impacts your car’s resale value. A well-maintained vehicle can command a higher price and is more attractive to buyers.
