Yes, a car can absolutely reach 300,000 miles, but it's not a given for every vehicle. Achieving this high mileage is the result of a deliberate combination of factors: choosing a model known for reliability, adhering to a strict and proactive maintenance schedule, and adopting gentle driving habits. It's less about luck and more about consistent, informed care over many years.
The single most important factor is preventative maintenance. This means following the factory service schedule found in your owner's manual meticulously, not just changing the oil when you remember. Key items like timing belts, coolant flushes, and transmission fluid changes are critical to preventing catastrophic failures. Using high-quality fluids and parts also contributes significantly to longevity.
Your choice of vehicle plays a huge role. Some brands and models have a proven track record of durability. Often, cars with simpler, naturally-aspirated engines and conventional automatic transmissions have fewer complex components that can fail over time. Here are some models frequently cited by sources like Consumer Reports and iSeeCars.com for their potential to reach high mileages:
| Vehicle Model | Powertrain Configuration | Notable High-Mileage Trait |
|---|---|---|
| Toyota Avalon | V6, Automatic | Known for exceptionally smooth and durable operation. |
| Ford F-250 (Diesel) | Turbo Diesel V8, Automatic | Built for heavy-duty work; diesel engines are inherently long-lasting. |
| Honda Accord (V6) | V6, Automatic | Honda's engineering and manufacturing precision aid reliability. |
| Toyota Sequoia | V8, Automatic | Body-on-frame SUV built on a robust truck platform. |
| Chevrolet Suburban | V8, Automatic | Similar to the Sequoia, its truck-based design promotes durability. |
| Lexus LS 460 | V8, Automatic | Combines Toyota reliability with luxury-grade components. |
| Toyota Camry (4-cyl) | 4-Cylinder, Automatic | Simplicity and widespread parts availability make maintenance easy. |
Finally, how you drive matters. Aggressive acceleration and hard braking put extra stress on the engine, transmission, and brakes. Consistent highway driving is generally easier on a car than constant stop-and-go city miles. Ultimately, getting to 300,000 miles is a marathon that requires a partnership between you, the owner, and a well-built machine.

From my experience turning wrenches, it's all about the oil. I've seen plenty of Toyota and Honda four-cylinders hit 300k because their owners never missed an oil change. The engines that fail early are the ones that get sludge from cheap oil and long intervals. Stick to the manual, use good synthetic oil, and address small problems like leaks or weird noises before they become big, expensive ones. The car will tell you what it needs if you listen.

My dad's 2002 F-250 just passed 320,000 miles. It's a diesel, and he's used it for his construction business its whole life. It's not fancy, but he's religious about maintenance. Reaching that milestone gives you a real sense of pride. It feels like you've truly gotten your money's worth. You develop a relationship with the vehicle, learning all its quirks and sounds. It becomes a testament to taking care of your things.

For our company fleet, we target vehicles known for low long-term costs. We prioritize models like the Ford Crown Victoria (when they were made) and Chevrolet Impalas because we have data showing many can reliably reach 250,000-300,000 miles with proper care. This is a financial decision. It maximizes our investment and minimizes downtime. The key is a centralized maintenance log and using trusted mechanics to ensure no service interval is ever missed.

I drive a lot for work, so I need a car I can depend on without huge repair bills. I did my research and bought a used Camry with 80,000 miles. My goal is to drive it until the wheels fall off. I follow the maintenance schedule to the letter and keep all my receipts. It's not exciting, but it's peace of mind. I'm at 220,000 miles now, and it still runs perfectly. I'm confident I'll hit 300,000 by just staying on top of the basics.
