How many miles can I get on a Subaru Ascent?
Most Subaru Ascents deliver roughly 400–520 miles per tank, depending on driving conditions and trim; highway driving yields more miles per tank than city driving.
Fuel-tank size and EPA fuel-economy ratings
The current Subaru Ascent typically uses a 19.3-gallon fuel tank. With the standard all-wheel-drive setup and the 2.4-liter turbo engine, EPA ratings are about 21 mpg in the city, 27 mpg on the highway, and 23 mpg combined. These figures represent typical driving and can vary by model year and configuration.
Before reviewing the numbers below, note that actual range depends on how you drive, the load you carry, road grade, weather, and tire condition. The following figures provide a practical baseline based on common specifications.
- Fuel-tank capacity: about 19.3 gallons (roughly 73 liters).
- EPA fuel economy (AWD, 2.4L turbo): ~21 mpg city / ~27 mpg highway / ~23 mpg combined.
- Estimated per-tank range: city about 405 miles; highway about 521 miles; combined about 444 miles.
- Real-world range varies with terrain, cargo, driving style, and weather.
Keep in mind that these ranges are approximate averages. Real-world mileage can be higher or lower based on your specific driving conditions and maintenance.
How range varies by driving conditions
To help you plan trips and refueling stops, consider how different driving scenarios affect mileage.
- Urban/city driving (lower speeds, frequent stops): typically around 380–420 miles per tank, depending on traffic and idling time.
- Highway or steady-cruise driving (higher speeds, fewer stops): often near the upper end, about 500–520 miles per tank under favorable conditions.
- Mixed driving (a combination of city and highway): commonly in the 420–450 mile range.
These ranges are approximate and assume a full tank with normal maintenance. Variations of 50–100 miles are common based on conditions and driving style.
Tips to maximize range
Improving miles per tank comes down to driving habits, maintenance, and load management. Here are practical steps you can take.
- Maintain steady speeds and avoid rapid acceleration or hard braking to reduce fuel use.
- Keep tires inflated to the recommended pressure; underinflation lowers efficiency.
- Minimize extra weight and aero drag (roof racks, heavy cargo) when not needed.
- Use cruise control on highways to maintain a consistent, efficient pace where appropriate.
- Ensure regular maintenance (air filters, spark plugs, fuel system) to keep engine efficiency high.
By adopting these practices, you can approach the higher end of the vehicle’s range, though actual results will still vary with conditions and driving style.
Bottom line
The Subaru Ascent typically delivers about 400–520 miles per tank, with highway driving offering the best range and city driving the lowest. Exact figures depend on model year, trim, drivetrain, and driving conditions.
Summary: Plan for roughly 450 miles per tank as a practical benchmark, but be prepared for a wider spread (roughly 380–520 miles) depending on how you drive and where you drive.
Are subarus reliable after 100k miles?
Yes, Subarus can be reliable after 100,000 miles, but it is heavily dependent on consistent maintenance and addressing potential issues like head gaskets. With proper care, many Subarus can last for 200,000 to 300,000 miles or more.
Factors for reliability after 100k miles
- Maintenance is crucial: This is the single most important factor. Regularly following the manufacturer's service schedule for things like oil changes, fluid flushes, and timing belt/chain replacements is essential for longevity.
- Common issues to check for:
- Head Gaskets: This is a well-known potential issue in older EJ engines, often occurring between 100,000 and 130,000 miles.
- Engine reseals: Newer FB engines might require a more involved reseal around 150,000 miles.
- CVT transmission: Early models of the Continuously Variable Transmission (CVT) had some documented problems, so it's worth researching the specific model year.
- Model and engine differences: Older EJ engines are known for head gasket issues, while newer FB engines have a timing chain instead of a belt but may need a different type of service later on.
- Inspection and service history: If buying a used Subaru, a clean vehicle history report and documented service records are vital.
How to ensure long life
- Follow the 100k-mile service: At the 100,000-mile mark, be prepared for a service that combines previous intervals and includes replacing spark plugs, transmission fluid, and differential fluid.
- Preventive maintenance: Continue with all standard maintenance items like oil changes, tire pressure checks, and air filter replacements to prevent other components from failing prematurely.
- Be prepared for other repairs: Once a car hits 100,000 miles, various other parts like suspension components, wheel bearings, and the alternator may start to need replacement, even if the major mechanical parts are still sound.
Is the Subaru Ascent a dependable vehicle?
The 2025 Subaru Ascent scored the top possible 5-Star overall rating from the NHTSA, and the excellent Top Safety Pick award from the IIHS.
How many miles will a Subaru Ascent last?
200,000 to 250,000 miles
On average, a well-maintained Subaru Ascent can last anywhere from 200,000 to 250,000 miles! To put that into perspective, this means if you drive about 12,000 miles per year, your Subaru Ascent could easily last 15 to 20 years.
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.
