A car can typically drive until it runs out of fuel or battery charge. For a standard gasoline car with a 15-gallon tank averaging 25 MPG, that's about 375 miles. However, a car's total lifespan—how many miles it can drive before major mechanical failure—often exceeds 200,000 miles with proper maintenance. The real answer depends on whether you're asking about a single tank/charge or the vehicle's entire operational life.
Key Factors Influencing Driving Distance per Tank/Charge:
| Factor | Impact on Range | Example/Note |
|---|---|---|
| Fuel Tank Capacity | Directly proportional to range. | A truck with a 36-gallon tank can often drive over 600 miles. |
| Fuel Economy (MPG) | Higher MPG = longer range. | Hybrids like the Toyota Prius (50+ MPG) can exceed 600 miles on a smaller tank. |
| Driving Conditions | Highway cruising maximizes range; city driving reduces it. | Stop-and-go traffic can lower efficiency by 15-20%. |
| Vehicle Load & Terrain | Heavy loads and hilly terrain decrease range. | Roof racks and towing have a significant negative impact. |
| EV Battery Capacity | Measured in kWh; larger capacity = longer range. | Many new EVs offer 250-350 miles of range. |
| EV Driving Style & Climate | Aggressive driving and extreme cold can cut EV range by 30% or more. | Using heat or AC heavily affects battery usage. |
For a vehicle's total lifespan, consistent maintenance is the critical factor. Following the manufacturer's service schedule for oil changes, tire rotations, and fluid checks is paramount. Addressing small issues before they become major problems can help a car reliably reach 200,000 miles or more. Ultimately, how long a car can drive is a combination of its engineering and the owner's commitment to upkeep.

I think about it in terms of my weekly routine. My sedan gets around 350 miles on a full tank. That's enough for my commute, errands, and a weekend trip without needing to stop for gas. It's not really about the car's lifetime miles for me, but how far it can go between fill-ups. I just make sure to get the oil changed on time, and it's been running fine for years. For a single trip, you're looking at a few hundred miles, which is plenty for most people's needs.

From a test driver's perspective, we measure "driveability" in cycles. Modern engines and transmissions are designed for longevity far beyond 150,000 miles. The limiting factor isn't the engine block itself, but wear items: the battery, tires, belts, and seals. With scrupulous maintenance—meaning you don't skip services—a well-built car can easily surpass a quarter-million miles. I've seen vehicles with over 300,000 miles that still run smoothly because their owners were diligent. The car's potential lifespan is often much longer than most people assume.
