How big is a 2016 Subaru Forester gas tank?
The gas tank capacity for most 2016 Subaru Forester models sold in the United States is 16.9 gallons (64 liters).
That figure represents the tank's total volume. Your real-world driving range depends on the engine and transmission, as well as your driving style and conditions; with typical fuel economy in the mid-20s to high-20s miles per gallon, a full tank covers several hundred miles.
Fuel tank specifications
Below are the key numbers and context you should know about the 2016 Forester's fuel storage, your possible driving range, and the factors that affect it.
Before listing the main figures, here's a quick overview of what to expect from the tank in daily use.
- Tank capacity: 16.9 US gallons (64 liters).
- Estimated driving range: With typical 2016 Forester fuel economy in the mid-20s to high-20s mpg, a full tank generally yields about 450–550 miles, depending on road mix and driving style.
- Fuel gauge and reserve: The gauge shows remaining fuel, but the published figure is the total tank volume; there is a small reserve portion and the exact reserve amount is not officially published by Subaru.
- Market variations: The 16.9-gallon figure applies to North American-spec models; other markets may quote very similar totals, with minor variations due to measurement standards or model year changes.
In everyday use, the Forester’s 16.9-gallon tank offers solid range for commuting and road trips, especially when cruising on highways where efficiency tends to rise.
Driving range and efficiency notes
EPA fuel-economy figures for the 2016 Forester with the 2.5-liter engine and continuously variable transmission (CVT) are generally in the mid-to-high 20s miles per gallon combined, with higher numbers on highway-only driving and lower numbers in city driving. Real-world results vary with load, terrain, climate, and driving habits, but the full tank typically supports hundreds of miles of travel between refuels.
Practical tips for maximizing range
To stretch range from a single tank, keep a smooth driving style, maintain proper tire inflation, and perform regular maintenance (air filter, spark plugs, and engine tunes). Avoid aggressive acceleration and excessive idling, especially in city driving.
Summary
The 2016 Subaru Forester’s gas tank capacity is 16.9 gallons (64 liters). With typical fuel economy for the year, drivers can expect roughly 450–550 miles of range per tank under normal conditions, with actual distance varying based on driving mix and conditions. This makes the Forester well-suited for both daily commuting and longer trips, provided you monitor the fuel gauge and refuel before necessary.
How many miles can a Subaru Forester go on a full tank?
A Subaru Forester can go between approximately 431 miles (city driving) and 540-547 miles (highway driving) on a full tank, depending on the model year and driving conditions. The 16.6-gallon tank is a common feature, and modern models like the 2023 and 2024 often advertise a highway range of around 540 miles. Actual mileage will vary based on driving habits, terrain, and payload.
- Highway driving: Around 540-547 miles
- City driving: Approximately 431 miles
- Fuel tank capacity: 16.6 gallons is a common capacity
- Factors influencing range: Actual mileage is affected by driving behavior, tire pressure, payload, and road conditions

What is the most common problem with the Subaru Forester?
The most common problem with the Subaru Forester is the continuously variable transmission (CVT), which can suffer from issues like shuddering, delayed acceleration, and whining noises, and may require expensive repairs. Other frequent issues include problems with the engine (especially oil consumption), the electrical system, and, in certain model years, issues with windshields cracking and batteries dying quickly.

Transmission (CVT)
- Shuddering and jerking: This often occurs when accelerating from a stop.
- Delayed acceleration and slipping: The engine revs up but the car doesn't speed up as expected, which can be dangerous when merging.
- High-pitched whining: This can be a sign of worn pulley bearings inside the transmission.
- Repair cost: CVTs are often not rebuildable and require a complete, expensive replacement.
Engine
- Excessive oil consumption: Many model years, particularly from the 2014-2018 generation, are known for burning through oil rapidly.
- Oil leaks: Leaks, often requiring expensive engine replacements, are another reported problem.
Electrical and other issues
- Electrical malfunctions: Issues can range from infotainment system glitches and GPS errors to more serious problems like a battery dying prematurely or the EyeSight safety system turning off unexpectedly.
- Air conditioning (AC): Some models experience AC failure that can be costly to fix.
- Windshields: In the 2019-2024 generation, windshields can crack from small chips.
- Airbag malfunctions: Older models, such as the 2009-2011, have been associated with malfunctioning airbags.
