With the hustle and bustle of everyday life, it’s not surprising that our vehicles often get taken for granted. However, considering the vital role they play in our daily routines, ongoing vehicle maintenance should be a top priority. Fortunately, most aspects of maintenance are fairly simple and, in many cases, can be performed independently. Take a minute to review these car care tips from five Diamond Certified Expert Contributors.

1. Tire maintenance: Walee Gon of Faxon Garage 

When a vehicle’s tires are under-inflated, it leads to increases in fuel usage, braking distance and tread wear. That’s why you should regularly monitor your tires’ inflation levels using a hand-held tire pressure gauge.When inflating tires, follow the manufacturer-recommended inflation level (PSI) rather than what’s printed on the tires themselves. The correct PSI can be found on your driver’s side door jamb and in your owner’s manual. Besides maintaining proper inflation, have your tires rotated every 10,000 miles to ensure even wear.

2. Engine air filter replacement: Wayne Pentecost of Wayne & Son’s Automotive Repair, LLC

When an air filter isn’t regularly replaced, the excessive dirt buildup can cause it to become clogged, which restricts engine ventilation. When an engine isn’t able to “breathe” properly, it’s more likely to run rich, which means it uses more gasoline than it’s supposed to. To avoid this, periodically check the condition of your engine air filter and replace it as needed.

3. Monitoring engine oil: Frank Walsh of William Michael Automotive

With the growing sophistication of both engines and oil products, recommended oil change intervals are continually expanding. While this is ostensibly beneficial, it poses a risk for less-than-conscientious vehicle owners. More and more, auto technicians are seeing cars come into their shops with dangerously low oil levels, due to owners driving thousands miles without giving a second thought to checking and replenishing fluids. So, remember to periodically check your oil between services and add to it as needed.

4. On-the-road visibility: Joel Ramos Diaz of American Canyon Collision Center

While often overlooked, visibility is vital to ensure safety while driving. Since headlight lenses can get “cloudy” as their UV coating breaks down, be sure to have yours polished and the UV coating reapplied periodically. Windshields with large cracks should be replaced as soon as possible, especially if a crack directly obstructs your visibility (this can also earn you a ticket). Also, replace windshield wipers regularly, as their performance starts to diminish with increased wear.

Designed to filter out elements like dust and pollen, a cabin air filter provides clean air for a vehicle’s driver and passengers. However, many people don’t even know what a cabin filter is, which is why the filters in some vehicles never get changed. In this case, the filter can become inundated with dirt and grime, and it can even accumulate mold, which causes it to have the opposite of its intended effect. To avoid compromising air quality in your vehicle, have your cabin filter changed every 15,000 miles, as per manufacturer recommendations.
