How many miles can you get out of a 2001 Subaru Outback?

The 2001 Subaru Outback’s mileage depends on the engine and transmission. In general, the most common setup—2.5-liter four-cylinder with an automatic transmission—delivers about 22 miles per gallon combined, while manual transmission versions can be a bit more efficient, and a 3.0-liter V6 variant tends to be less economical. With a typical fuel tank of roughly 16 gallons, you can expect roughly 320 to 450 miles per tank depending on configuration and driving conditions.


EPA mileage estimates by engine and transmission


The following figures reflect the U.S. market configurations for the 2001 Outback. Actual results can vary based on driving style, terrain, and maintenance.



  • 2.5L flat-four with 4-speed automatic transmission: 20 mpg city / 26 mpg highway; about 22 mpg combined.

  • 2.5L flat-four with 5-speed manual transmission: around 23 mpg city / 28 mpg highway; about 25 mpg combined.

  • 3.0L H6 (available on select trims): approximately 18 mpg city / 23 mpg highway; about 20 mpg combined.


These EPA numbers illustrate the typical trade-offs between power, drivetrain, and efficiency. The common 2.5L automatic configuration represents the baseline for many owners, with the manual offering a modest boost in economy, and the V6 variant delivering more power at the expense of efficiency.


Real-world performance


Real-world fuel economy often diverges from EPA estimates based on driving habits and conditions. In everyday use—urban commutes, highway trips, and carrying cargo or passengers—the Outback generally lands in the low 20s to mid-20s for combined mileage on the 2.5L automatics, with manual versions occasionally posting slightly higher numbers. Proper maintenance, proper tire inflation, and a light foot can help approach the higher end of these ranges.


Fuel range per tank


With a typical fuel tank capacity around 16 gallons, here are approximate ranges per full tank for common configurations. These are ballpark figures intended to illustrate potential mileage, not guarantees.



  • 2.5L automatic: Combined about 22 mpg → roughly 340 miles per tank; city driving around 320 miles; highway driving around 420 miles.

  • 2.5L manual: Combined about 25 mpg → roughly 400 miles per tank; city driving around 365 miles; highway driving around 445 miles.

  • 3.0L H6: Combined about 20 mpg → roughly 320 miles per tank; city driving around 285 miles; highway driving around 360 miles.


Note that actual ranges vary with driving style, terrain (hills vs. flat), climate, cargo load, and tire choice. If you’re planning a long trip, consider these factors and monitor your fuel gauge accordingly.


Tips to maximize fuel economy


Small adjustments can help you get closer to the higher end of the mileage range. Before relying on these tips, confirm they’re appropriate for your vehicle’s condition and maintenance schedule.



  • Keep tires properly inflated to the recommended pressure.

  • Perform regular maintenance: spark plugs, air filters, and oil changes on schedule.

  • Avoid aggressive acceleration and excessive idling; cruising smoothly saves fuel.

  • Lighten the load when possible; remove unnecessary roof racks or cargo if not in use.


Regular maintenance and mindful driving can meaningfully influence the Outback’s actual miles per gallon and per-tank range, especially on older vehicles where engine efficiency can wane without upkeep.


Summary


For a 2001 Subaru Outback, expect roughly 22 mpg combined on the common 2.5L automatic configuration, with manual transmissions typically delivering a bit more and the 3.0L V6 variant generally offering lower efficiency. A full tank will usually yield about 320 to 450 miles, depending on engine, transmission, and driving conditions. Real-world results vary, but with proper maintenance and economical driving habits, you can approach the higher end of these ranges.

Is it worth buying a Subaru with over 200k miles?


You should only consider buying a Subaru with 200k miles if it has a complete maintenance history, has had major components replaced, and passes a thorough pre-purchase inspection. While Subarus can last beyond 200k miles, a vehicle at this mileage will have significant wear and tear and is likely to need costly repairs soon.
 
What to look for

  • Maintenance records: A well-maintained Subaru is crucial for longevity. Look for consistent service, especially for the timing belt (if applicable), head gaskets, and other engine components. 
  • History: An inspection of the vehicle history report is important to understand the car's past. Look for signs of accidents or a history of consistent use. A vehicle with one or two owners is often a better bet. 
  • Pre-purchase inspection: Have a trusted mechanic thoroughly inspect the car, focusing on the engine, transmission, suspension, and any other potential failure points at this mileage. 
  • Past repairs: Ideally, major repairs like the head gasket, water pump, and transmission should have already been completed. 

Potential issues at 200k miles
  • Engine and transmission: These are the most expensive components to replace. Be prepared for potential failures or significant maintenance costs. 
  • Suspension and brakes: Components like the suspension, brakes, and exhaust can rust out or wear out, requiring replacement. 
  • Other components: Expect a higher likelihood of smaller issues like worn-out seals, bushings, and other small parts that can lead to costly repairs if not addressed. 

When to avoid
  • No service history: Without records, it's a high-risk purchase. You won't know how well the car was maintained. 
  • Major issues found in inspection: If a pre-purchase inspection reveals any major problems with the engine, transmission, or other core systems, walk away. 
  • High number of owners: A car with many owners is more likely to have been poorly maintained or neglected. 



What is considered high mileage for a Subaru Outback?


For a Subaru Outback, "high mileage" generally means anything over 150,000 miles, but due to their durability, many properly maintained Outbacks can last 200,000 to 300,000 miles or more. A mileage in the 150,000 to 200,000 range is often considered high, but a vehicle's longevity heavily depends on its maintenance history. 
What to consider with high-mileage Outbacks

  • Maintenance is key: A well-maintained Subaru can last significantly longer. Regularly check maintenance records to see if major services like timing belt replacements (on older models) have been performed. 
  • Potential repairs: Even with good maintenance, components like suspension, brakes, and exhaust can show wear at 150,000 miles or more. Some models may also experience oil leaks or transmission issues as they age. 
  • Longevity: Some models have been reported to reach well over 300,000 miles, with a greater than average chance of surpassing 250,000 miles. 
  • Purchasing advice: When buying a high-mileage Outback, always have a trusted mechanic perform a pre-purchase inspection to assess the vehicle's condition and identify any potential upcoming issues. 



Can a Subaru last 300,000 miles?


On average, a well-maintained Subaru Outback can last anywhere from 200,000 to 300,000 miles! For perspective, this means if you drive about 12,000 miles per year, your Subaru Outback could easily last 16 to 20 years.



How many miles will a 2001 Subaru Outback last?


between 200,000 and 300,000 miles
Subaru Outbacks are praised for their longevity. With regular maintenance, you can expect yours to last between 200,000 and 300,000 miles or from 10 to 20 years.
