Maintaining a car might not be rocket science, but many drivers unknowingly make simple maintenance mistakes that can cost them time, money, and safety in the long run. Howard Wilner of Sudbury, MA, an experienced automotive expert, shares the most common car maintenance errors and offers straightforward advice to help drivers keep their vehicles running smoothly.

Car maintenance doesn’t have to be complicated, but it does require regular attention. Even small oversights can lead to major problems down the road. Whether driving a new vehicle or an older model, staying on top of basic maintenance tasks is one of the smartest things a car owner can do.

Ignoring the Check Engine Light

When the check engine light comes on, many people choose to ignore it, thinking it’s no big deal. In reality, it’s a warning sign that something needs attention. It could be a small issue, like a loose gas cap, or a serious one, such as engine trouble. Delaying action may lead to more costly repairs.

Skipping Oil Changes

Regular oil changes are critical for engine health. Oil keeps engine parts lubricated and prevents wear and overheating. Neglecting oil changes can cause engine damage over time. Most vehicles need an oil change every 5,000 to 7,500 miles, depending on the type of oil and manufacturer recommendations.

Forgetting Tire Maintenance

Tires need more than just occasional air. Drivers should check tire pressure at least once a month and rotate tires every 5,000 to 8,000 miles. Worn-out or underinflated tires affect handling, fuel economy, and safety. Proper tire care extends their lifespan and ensures better performance on the road.

Overlooking Wiper Blade Replacement

Wiper blades are often neglected until it’s too late. If they leave streaks, squeak, or don’t clear the windshield effectively, it’s time for a replacement. Driving in poor weather with damaged wipers can compromise visibility and increase accident risk. Replacing them once or twice a year is usually enough.

Using the Wrong Fuel

Some drivers think using premium fuel in a regular car will improve performance. However, using higher-octane fuel than necessary doesn’t benefit most vehicles. It’s best to follow the manufacturer’s fuel recommendation to avoid wasting money and ensure proper engine function.

Not Checking Fluid Levels

Howard Wilner of Sudbury, MA emphasizes that beyond engine oil, vehicles rely on other essential fluids - like transmission fluid, brake fluid, coolant, and windshield washer fluid to run efficiently. Neglecting these can lead to serious mechanical problems. A monthly fluid check or a quick inspection during routine service can prevent larger problems.

Delaying Minor Repairs

Strange noises, warning lights, or minor leaks often go ignored. However, waiting too long to address small issues can turn them into major repairs. Fixing problems early can save money, avoid breakdowns, and keep the vehicle safe and reliable.

Maintaining with Confidence

Staying proactive with car maintenance doesn’t require advanced skills or a big budget. Simple habits - like checking fluids, changing oil, and paying attention to warning signs - go a long way in preventing major problems. Good maintenance improves performance, saves money, and most importantly, keeps drivers and passengers safe.
