Going The Extra Mile - Literally

Is There One Thing About Your Car You'd Change?

Like most drivers, we have been ingrained to change the oil in your car every 3,000 miles. But today’s engines and synthetic oils have changed the game. That means you might be able to let those miles roll by a little longer before you’re due for another oil change. So, let’s take a look at what it really means to go the extra mile with your oil.

Do You Really Need an Oil Change Every 3,000 Miles?

For years, 3,000 miles has been the go-to benchmark, but advancements in synthetic oil mean some cars can go much longer between changes. Unlike conventional oil, which can break down more quickly, synthetic oil is designed to handle higher temperatures, resist sludge buildup, and protect your engine over longer distances. That’s why many cars running on synthetic oil can go 7,500, 10,000, or even 15,000 miles between oil changes, depending on the make and model. Always check your car manufacturer's recommendations to make sure you’re using the correct oil type for your vehicle.

Quick Tip:

Before you leave the oil change shop, check the mileage sticker they’ve put on your windshield. It’s often set to the 3,000-mile mark out of habit—even if you’re using synthetic oil that could last far longer. It never hurts to double-check that the recommendation matches the type of oil your car actually uses!

Mileage Reminders: Are They Accurate?

Most newer cars have built-in mileage reminders for oil changes, but are they set specifically for the kind of oil you’re using? The short answer: not always. Many mileage reminders are based on a conventional oil schedule, so if you’re using synthetic, it’s worth looking into whether that reminder can be adjusted.

If you’re not sure, ask your car manufacturer or dealership if your car’s reminder can be calibrated for synthetic oil. And if it can’t, don’t worry—just keep track of your oil type and recommended change intervals to stay on top of it. It’s one extra step, but it ensures you’re getting the best performance from your car.

Resetting the Oil Change Reminder

If you’ve recently switched to synthetic or just want to reset your oil change reminder, many cars make it easy to do. For most models, you can find instructions in the owner’s manual, or you can search online for a quick walk-through. Generally, resetting is as simple as pressing a few buttons on the dashboard. But if you’re ever unsure, your dealership or mechanic can easily handle it for you.

When Going the Extra Mile Means… Finding a New Ride

So, you’ve mastered the art of oil changes, synthetic vs. conventional, and mileage reminders. But sometimes, no amount of maintenance can turn back the clock on an aging car. When repairs start piling up or your car just isn’t as dependable as it used to be, it might be time to think about an upgrade.

And that’s where we come in—to help you find a car that fits your needs, lifestyle, and budget perfectly. Think of us as your personal pit crew, ready to go the extra mile to make sure your trade-in is seamless and enjoyable. Because finding the right ride shouldn’t just be about reaching your destination—it should be about enjoying every mile along the way.

Car Issues Your Dashboard Won't Tell You About

Dazzled by the Dashboard: What Lies Beyond the Glow

You may think you know your car well, but there’s more happening beneath the surface than your dashboard reveals. Sure, the dashboard lights up for issues like low oil or tire pressure, but it doesn’t cover everything. There are many hidden components and features that work tirelessly behind the scenes, keeping your car running smoothly without ever triggering a warning light. While you're focused on the engine, transmission, and those dashboard alerts, there are a lot of car issues that go unnoticed until they become a problem.

Drain Holes: The Unsung Water Fighters

Did you know that your car has many drain holes for water? While they’re out of sight, the effects of clogged drains are not. These tiny openings help your car stay dry by channeling water out before it can get into places it doesn’t belong, like your floorboards or trunk. Here’s where you should look:

  • Doors
    At the bottom of your car doors are small holes designed to drain water that slips past the window seals. If these get clogged with dirt and leaves, you might end up with soggy carpets and a musty smell. A quick visual check now and then can save you from bigger problems, like rust or mildew.

  • Sunroof 
    If your car has a sunroof, there are drain tubes to channel rainwater away from the roof. If clogged, they can lead to water leaks into your headliner or even drip onto your seats. If you notice wet spots near the edges of your sunroof, it’s time to clean those drains. A quick rinse with water or air pressure can clear them up.

  • Trunk
    The weather seals around your trunk aren’t always perfect. Any leaks in the trunk can lead to standing water in your spare tire well (yes, that’s a thing). Check under the mat in your trunk every once in a while. If you find moisture, the trunk drains might need a good cleaning.

  • Windshield Cowl
    The area at the base of the windshield where water runs off can easily become clogged when leaves or debris pile up. This can lead to water leaks into the cabin or, worse, your car’s electrical system. Clear them out regularly to avoid water leaks or electrical issues in the future.

A Fan of Quiet Calls? So Is Your Car!

When you're driving and talking on the phone via Bluetooth, your car automatically lowers the fan speed or adjusts the airflow direction so that the person on the other end of the call doesn’t hear a blast of air drowning out your voice. Next time you're on a call and the person on the other end struggles to hear you, it might not be your phone; it could be your car’s climate control feature acting up. But not all noise comes from inside the car. If your door seals are worn or cracked, external noise like wind and road noise can seep into the cabin, making it harder for the person on the other end of the call to hear you clearly. You may not notice it, but they will.

Door Seals: Keeping Water and Noise Out

Your car’s door seals work hard to reduce not only water leaks but also excess wind noise. These rubber seals around your car’s doors and windows are designed to keep your ride quiet and comfortable. However, they can dry out, crack, or peel over time, letting unwanted noise sneak in and even affecting your phone calls.

If you notice wind noise or water trickling in during heavy rain, your seals might be in need of some attention. A quick inspection can help you avoid bigger problems down the road.

Cabin Air Filter: The Silent Smell-Maker

You can’t see your cabin air filter, but you can definitely smell it when it’s neglected. Over time, this filter gets clogged with dust, pollen, and all sorts of debris, which makes your car’s ventilation system work harder and could make your car smell like a damp basement. If your car’s air smells musty, stale, or just downright unpleasant when you turn on the A/C, it’s probably time for a new filter. It's a simple fix, and you’ll instantly make your drives fresher and more pleasant.

Pothole Problems: Getting Pulled In The Wrong Direction

We've all felt that jarring thunk when hitting a pothole. Not only is it uncomfortable, it can mess with your car's alignment. If you notice your car pulling to one side or your steering wheel seems off-center, chances are your wheel alignment has been knocked out of place. Left unchecked, poor alignment can lead to uneven tire wear and make handling more difficult, which is both unsafe and costly in the long run.

But that’s not all. Hitting a pothole, curb, or parking block can affect your headlight alignment. Most of us only think about headlights when they go out or aren’t as bright as they used to be. However, after significant impacts like these, your headlights can shift slightly out of alignment. If one light seems to be shining higher than the other, or if oncoming drivers keep flashing their bright lights at you, it could be that your headlights are pointing in the wrong direction.

Beyond the Dashboard: Not Your Usual Checklist

Your dashboard does a great job of warning you about things like low oil or tire pressure, but it doesn’t tell you the whole story. There are countless hidden features quietly doing their part to keep your car running smoothly, without ever lighting up a warning. These small, often-overlooked details might not seem like a big deal, but taking a few minutes to check and maintain them can save you from major headaches down the road.

Most of these fixes are easy to spot and simple to take care of, even if you’re not a car expert. Next time you're giving your car a once-over, don't just rely on what the dashboard tells you. Take a moment to check these hidden heroes, and keep your ride smooth, dry, and drama-free.

While staying on top of these hidden features not only keeps your car running smoothly, it also helps maintain its value. Regular attention to components like seals, drains, and alignment can prevent costly damage down the road and keep your car in great shape. However, as cars age, even with the best care, there comes a point when the cost and effort of maintenance start to wear you down. If you’re finding that these systems need more frequent attention, it might be time to consider trading in your car for something newer and less demanding.
