When it comes to Northwest Arkansas, there are plenty of myths that circulate, leading to confusion and potentially costly mistakes. As a vehicle owner, it’s important to separate fact from fiction to make informed decisions about your car’s maintenance and repairs. In this article, we’ll debunk some of the most common auto repair myths and explain the truth behind them.

1. Myth: You Should Always Replace All Four Tires at the Same Time
It’s a common belief that if you need to replace one tire, you should replace all four. While it’s generally recommended to replace tires in pairs (two at a time), replacing all four may not always be necessary unless they are all worn out or damaged beyond repair.

The Truth: It’s not always required to replace all four tires unless they are significantly worn or your vehicle is all-wheel drive (AWD). For front- or rear-wheel-drive vehicles, replacing just the two tires on the same axle may be sufficient. However, if the new tires are much thicker than the old ones, they may cause issues with handling or cause uneven wear, so it's important to ensure that the new tires match in terms of tread depth and size.

Why It Matters: Replacing all four tires can be expensive, so it’s helpful to understand when it’s actually necessary. Always consult your mechanic to assess the condition of your tires and determine the best course of action.

2. Myth: A Higher-Price Repair Shop Means Higher Quality Work
Some people believe that the more expensive auto repair shops automatically offer better quality work. While it’s true that certain high-end shops may have advanced tools or highly trained mechanics, a high price doesn’t always guarantee better service.

The Truth: Price doesn’t always correlate with quality. A shop’s reputation, customer reviews, certifications, and technician experience are more important indicators of quality. Many independent or local shops provide excellent service at a fraction of the cost of dealerships or high-end establishments.

Why It Matters: Overpaying for repairs can be avoided if you understand that higher prices don’t always equal better results. Be sure to compare quotes, check for certifications, and read reviews to assess the quality of the shop.

3. Myth: You Only Need to Change Your Oil Every 3,000 Miles
The 3,000-mile oil change rule is one of the longest-standing auto repair myths, but it is not always accurate in today’s world of advanced engine technology and high-quality oils.

The Truth: Many modern vehicles can go 5,000 to 7,500 miles between oil changes, and some newer models can even go longer. The 3,000-mile guideline was based on older vehicles and conventional oil, but with the advent of synthetic oils and improved engine designs, many vehicles can safely extend the time between oil changes.

Why It Matters: Following an outdated oil change schedule can waste both money and resources. It’s always best to check your vehicle’s owner manual for the manufacturer’s recommendation or ask your mechanic about the best schedule for your car.

4. Myth: You Can Fix Everything with a Quick Fix or DIY Solution
With the rise of DIY car repair tutorials online, it can be tempting to tackle complex repairs yourself, especially if you’re trying to save money. While some repairs, like changing the air filter or replacing wiper blades, are easy to do, others are best left to professionals.

The Truth: Attempting to repair complex issues, like engine problems, brake malfunctions, or electrical failures, without the proper skills or tools can cause more harm than good. Inaccurate repairs can lead to safety hazards, more extensive damage, and higher repair costs down the line.

Why It Matters: While DIY repairs can save money on simpler tasks, more complicated issues require expertise to ensure your car remains safe and functional. Always know your limits and call in a professional for repairs beyond your skill level.

5. Myth: Car Maintenance Is Only Necessary for Older Cars
Many car owners assume that once their car hits a certain age or mileage, regular maintenance and repairs are less important. This myth could not be further from the truth.

The Truth: Regular maintenance is crucial for both new and old cars. Even new vehicles require routine tasks such as oil changes, brake inspections, and tire rotations to keep running smoothly. Neglecting maintenance can lead to breakdowns, expensive repairs, and early wear on critical components.

Why It Matters: Preventative maintenance is the key to extending your vehicle’s lifespan and avoiding costly repairs. Regular checkups keep your car running efficiently, regardless of its age, and can help identify minor issues before they become major problems.

6. Myth: Premium Gas Makes Your Car Run Better
A common misconception is that using premium gasoline, even when your car is designed for regular unleaded fuel, will improve performance and longevity. In some cases, people believe premium gas will make their car run smoother or increase fuel efficiency.

The Truth: Most vehicles are designed to run on regular unleaded fuel, and using premium gas in an engine that doesn’t require it offers no tangible benefits. Unless your car specifically requires premium fuel (typically found in luxury or high-performance vehicles), using higher-octane fuel won’t improve engine performance or efficiency.

Why It Matters: Overpaying for premium gas when regular fuel is sufficient can cost you extra at the pump without providing any real benefits. Always check your vehicle’s manual to determine the correct type of fuel for your car.

7. Myth: If Your Car’s Check Engine Light Comes On, It’s a Major Problem
When the check engine light turns on, many car owners panic, thinking they’re facing an expensive repair or breakdown. While it can indicate a serious issue, it doesn’t always mean your car is in critical condition.

The Truth: The check engine light is a warning that something is amiss in your vehicle’s engine or emissions system, but it can range from a simple issue (like a loose gas cap) to more complex problems (like a malfunctioning oxygen sensor). A diagnostic check is necessary to determine the cause.

Why It Matters: Ignoring the check engine light or overreacting to it can lead to unnecessary repairs or delays in addressing an issue that could worsen. It’s important to have the vehicle diagnosed to identify the problem accurately.

8. Myth: You Don’t Need to Replace Air Filters Often
Air filters are an essential component of your vehicle’s engine system, but many car owners neglect to replace them regularly. Some believe that air filters only need to be replaced when they are visibly dirty or clogged.

The Truth: Air filters should be replaced at regular intervals, typically every 12,000 to 15,000 miles, or as recommended by your vehicle’s manufacturer. Even if the filter doesn’t look dirty, it can become clogged over time, reducing engine efficiency and fuel economy.

Why It Matters: Replacing a dirty air filter is a quick, inexpensive task that can improve engine performance and fuel economy. Neglecting it can lead to reduced engine efficiency, increased emissions, and higher repair costs down the line.

Conclusion
Auto repair myths can lead to confusion, wasted money, and unnecessary stress. By understanding the truth behind these common misconceptions, you can make smarter decisions about your car’s maintenance and repairs. Always rely on professional advice and manufacturer recommendations when it comes to your vehicle’s care. In doing so, you’ll ensure that your car runs efficiently and stays in great shape for years to come.
