7 Must-Know Engine Maintenance Tips for Every Car Owner

Engines are incredible feats of engineering, but even the best ones need a little TLC to keep running smoothly.Regular maintenance isn’t just about avoiding those frustrating breakdowns—it’s a smart way to save on gas, keep your car running longer, and make sure it’s always performing at its peak. Treat your engine right, and it’ll return the favor!

If you live in Utah, you know the weather likes to keep you on your toes. Freezing mornings, scorching summers, and those canyon drives can take a toll on your car. That’s why a little extra care goes a long way. Here are 7 easy engine tips to help keep your car running smoothly, no matter what Mother Nature throws your way.

1. Regular Oil and Filter Changes Matter More Than You Think 

Your engine runs on oil like we run on water—it’s essential. It keeps everything smooth, cool, and squeaky clean under the hood. But oil doesn’t stay fresh forever. Over time, it breaks down, gets dirty, and can actually start causing problems instead of solving them.

Most vehicles need an oil change every 3,000 to 7,500 miles. It depends on how—and where—you drive, as well as the kind of oil you use. 

Utah Drivers, Take Note: Bitter cold thickens oil, making it sluggish. Summer heat, on the other hand, can thin it out too much. Always go with what your manual recommends for seasonal driving. 

Stick to aregular oil change routine and don’t forget the filter—clean oil won’t help much if your filter’s clogged. 

2. Don’t Let Your Cooling System Slip 

Engines run hot—really hot—and it’s up to your cooling system to keep things under control. That’s where coolant (aka antifreeze) steps in. It works hard to pull heat away from the engine, making sure it doesn’t overheat and turn into a meltdown disaster.

Salt Lake summers are no joke, and those hilly drives can really put your engine to the test. Keep an eye on your coolant levels, watch out for any leaks, and don’t forget to get a coolant flush every couple of years to keep things running smooth.

Quick Tip: Always check coolant when your engine is cool. Burned fingers aren’t part of the maintenance plan. 

3. That Check Engine Light? Don’t Ignore It 

We’ve all had that moment—you’re driving, everything’s fine, and then, bam, that little orange engine light pops on. Maybe it’s just the gas cap. Maybe it’s something bigger. Either way, it’s not worth taking chances.

Small issues can snowball fast. Worse yet, in Utah, a glowing check engine light might mean you flunk your emissions test. That’s a hassle no one needs. 

Good news: Mobile services like SLC Fleet Pro can check things out without a trip to the shop. 

4. Change Spark Plugs and Ignition Parts on Time 

Spark plugs may be tiny, but they’ve got a big job: lighting the fuel-air mix that keeps your engine going. When they wear out, you’ll feel it—rough starts, sluggish response, poor mileage, or even stalling. 

Most last between 30,000 and 100,000 miles, depending on type and vehicle. Don’t wait for a warning light—staying ahead keeps your engine smooth and efficient. 

5. Inspect Belts and Hoses Before They Fail 

Belts and hoses aren’t glamorous, but they’re essential. Belts drive critical systems like the alternator and water pump, while hoses move fluids your engine depends on. 

They wear down over time—think cracks, leaks, or soft spots. Check them twice a year, or at each oil change. Not sure what to look for? A mobile mechanic can inspect them quickly while you’re parked at home or the office. 

6. Choose Quality Fuel and Clean the Fuel System Occasionally 

What you put in your tank matters. Low-quality gas can leave behind deposits that gunk up your fuel system. Over time, that build-up drags down performance and efficiency. 

Use top-tier fuel when you can, and run a fuel system cleaner every so often to clear out carbon deposits. 

Local Driving Tip: If you're often stuck in stop-and-go traffic, your engine's more prone to buildup—cleaners can really help here. 

7. Don’t Overlook the Engine Bay 

Yes, under-the-hood cleanliness matters. Dust, grease, even animal nests (yep, it happens) can cause trouble—from corrosion to electrical issues. 

You don’t need a detailer—just wipe down surfaces with a damp microfiber cloth, and steer clear of wiring and sensors. A clean engine bay also makes leaks or wear much easier to spot. 

Final Thought: Take Care Now, Save Later 

Your engine is the heartbeat of your car, and a bit of regular TLC can make all the difference.
