High-Mileage Cars

Wouldn’t it be nice to know your car will last for years? That you can buy it, drive it, and rely on it month after month, year after year, no matter how many miles the odometer registers?

You can.

The average age of a car on the road keeps climbing, currently 14 years. And no, these cars aren’t all sitting in a garage, only used to run errands a day or two a week. Many are driven daily, have high-mileage, and still operate well. What keeps them on the road is the way their owners handle regular maintenance.

There are two approaches.

1. Wait until you have a problem and then fix it.

2. Schedule regular maintenance to keep your car running well, fixing minor issues before they become major problems.

Guess which one ensures your vehicle will last longer?

What Is Considered a High-Mileage Car

The term “high-mileage car” doesn’t have a fixed definition—it varies based on perspective and advancements in automotive engineering. However, a car is often considered high mileage when it surpasses 100,000 to 150,000 miles on the odometer.

High-mileage cars are no longer the rarity they once were. Thanks to improvements in technology and manufacturing, many modern vehicles are built to last well beyond 200,000 miles with proper care. In fact, a high-mileage vehicle can remain reliable and efficient if maintained regularly and driven responsibly.

The Importance of Regular Maintenance for High-Mileage Cars

Just look at these examples.

We’re not saying you should expect one million miles on the car you drive. But we are willing to bet that each of these examples had owners who scheduled regular maintenance to keep their cars in good shape!

How Are High-Mileage Cars Different From Low-Mileage Cars

It may seem a little obvious, but we thought we’d share the differences between operations on high-mileage vs low-mileage cars.

While its core functionality remains intact, high-mileage cars require a bit more attention compared to their younger counterparts. Here’s how high-mileage cars differ:

Increased Wear and Tear

Every component in your car, from the engine to the suspension, experiences wear with every mile driven. High-mileage cars are more prone to issues like leaks, part failures, and reduced efficiency.

Fluid Degradation

Over time, essential fluids like engine oil, transmission fluid, and coolant degrade, reducing their effectiveness. Older vehicles may also be more susceptible to fluid leaks.

Reduced Efficiency

Engines in high-mileage cars may lose some efficiency due to worn components like piston rings, valves, or injectors. Regular maintenance can help mitigate these effects.

Potential for Corrosion

Vehicles driven through harsh weather or on salted roads are more likely to experience rust or corrosion, particularly on the undercarriage. Yes, just one more reason to give your car a good washing on a nice day after the infamous Colorado winter storms we get around here.

These are just a few of the reasons why high-mileage cars need a little more attention. With the right maintenance strategy, they can remain reliable and functional for years to come.

Things To Consider as a Part Of Your Monthly and Yearly Routines

So, you want to keep your car as long as possible. Eight, ten, twelve – your car was expensive – why not get your money’s worth? If this sounds like your gameplan, just know that cars thrive on consistent care. What does that look like? Here’s what we suggest:

Monthly Maintenance Checklist

Check Fluid Levels

Ensure your oil, transmission fluid, brake fluid, and coolant are at appropriate levels. Look for signs of leaks.

Inspect Tires

Check tire pressure and tread depth. Uneven wear could indicate alignment or suspension issues.

Monitor Warning Lights

Pay attention to any dashboard warning lights and address them promptly.

Listen for Unusual Noises

Strange sounds can be early indicators of mechanical problems.

Clean the Car

Wash and wax your car to protect the paint and prevent rust, especially in winter months.

Yearly Maintenance Checklist

Change Oil and Filters

High-mileage cars benefit from more frequent oil changes. Replace the oil filter at every change, and consider using high-mileage engine oil for added protection.

Inspect Belts and Hoses

Look for cracks, fraying, or signs of wear. Replace them proactively to avoid breakdowns.

Flush Fluids

Brake fluid, coolant, and transmission fluid should be flushed and replaced according to the manufacturer’s recommendations.

Check the Battery

Ensure the terminals are clean and corrosion-free. Test the battery’s charge and replace it if it’s nearing the end of its lifespan.

Inspect the Suspension and Steering

Worn suspension components can affect handling and safety. Have a mechanic inspect shocks, struts, and bushings.

Examine the Exhaust System

Check for rust, leaks, or excessive noise. A compromised exhaust system can affect performance and emissions.

See? Easy-peasy. Just use this list to create “to-do’s” on your calendar. That makes it easy to remember.

How To Plan Your Regular Maintenance Routine

We have a few more suggestions for you. Creating a maintenance schedule for your high-mileage car isn’t just about preventing problems. We believe it’s also about giving your car the best chance to thrive as it ages. Here’s a few more ideas:

Know Your Car’s History

If you’re not the first owner, see if you can get maintenance records from the previous owner to understand what’s been replaced or repaired. This helps you focus on areas that may need immediate attention.

Follow the Manufacturer’s Guidelines

Consult your car’s owner manual for maintenance intervals and recommended service. High-mileage cars may benefit from adjustments, like more frequent oil changes or the use of high-mileage oil.

Prioritize Key Areas

Engine Health: Replace spark plugs, clean fuel injectors, and ensure proper timing.
Transmission Care: Service the transmission and address any shifting issues promptly.
Brake System: Inspect pads, rotors, and fluid levels regularly to ensure stopping power.
Suspension and Alignment: Check for worn components and maintain proper alignment to avoid uneven tire wear.

Budget for Repairs and Upgrades

High-mileage cars may require unexpected repairs. Set aside a budget for maintenance and consider investing in upgrades, such as heavy-duty shocks, to extend the car’s lifespan.

Work with a Trusted Mechanic

Establish a relationship with a mechanic who understands your car’s needs. Regular visits can help identify potential issues before they become costly repairs.
