The fuel tank capacity of a car is an important factor in determining the range of a trip. The 2003 Subaru Legacy's fuel tank capacity is 16.9 gallons, according to one source. Another source states that the fuel capacity is 15.9 US gallons, which is approximately 60 liters. This discrepancy could be due to different measurement methods or variations in the car's specifications for that year. It's always a good idea to refer to the owner's manual or consult a Subaru dealer for the most accurate information regarding your specific vehicle.
| Characteristics | Values |
|---|---|
| Fuel tank capacity | 15.9 gallons (60 litres) or 16.9 gallons, depending on the source |
| Fuel mileage | Varies depending on the car's gas mileage, mph, and area of driving |
| Fuel gauge accuracy | Inaccurate; may show a hair below the full mark when full |

What You'll Learn
Fuel tank capacity depends on the car's gas mileage
The fuel tank capacity of a car depends on several factors, including the make and model of the car, the type of engine, and the specific racing series and regulations (in the case of race cars). The average car's fuel tank capacity typically ranges from 38 to 76 litres (10 to 20 gallons). However, this can vary significantly depending on the car. For example, two-cylinder cars usually have smaller fuel tank capacities, ranging from 40 to 45 litres. On the other hand, eight-cylinder cars often have larger fuel tank capacities, ranging from 60 to 114 litres.
The fuel tank capacity of a car also depends on the car's gas mileage, or fuel economy. The vehicle's mileage for each gallon of fuel depends on several conditions, such as maintenance, cargo, and passengers. Trip computers may calculate the estimated miles that can be travelled on the remaining fuel based on the vehicle's fuel economy during a specific driving period. These estimates may vary greatly depending on external conditions. Additionally, the fuel level in the tank may shift temporarily when the vehicle is not on level ground, such as when on a hill or travelling around a curve, affecting the fuel gauge reading.
The 2003 Subaru Legacy, for example, has a fuel tank capacity of 16.9 gallons. The fuel tank capacity for the Subaru Legacy varies depending on the model year. From 2010 to 2014, the gas tank size was 18.5 gallons. In 2015, the capacity decreased slightly, and from 2016 to 2019, the gas tank size remained at 18.5 gallons. The 2020 model had a capacity of 18.5 gallons, and the 2021 model had a capacity of 18.0 gallons. The 2022 and 2023 models had a capacity of 18.0 gallons, and the 2024 and 2025 models increased to 18.5 gallons.
It is important to note that the rated capacity of a fuel tank is only an estimate, and the actual capacity may vary by up to three percent due to design characteristics, the manufacturing process, and other factors. Additionally, the rated capacity may include only the usable portion of the fuel tank or both the usable and unusable portions. The unusable volume is the portion of the fuel tank's liquid capacity that is out of reach of the fuel pump, and the usable volume is the portion that can be delivered through the filler pipe when the vehicle is level.

The 2003 model is not listed, but the 2002 model has a capacity of 18.5 gallons
While the fuel tank capacity for the 2003 Subaru Legacy model is not explicitly listed, the 2002 model is stated to have a capacity of 18.5 gallons. This information provides a reasonable estimate for the 2003 model, as fuel tank capacities for consecutive years are often similar.
The fuel tank capacity of a vehicle is an essential factor in determining the range of a trip. The Subaru Legacy's fuel tank size, combined with its fuel mileage, offers varying ranges depending on the model year and specific trim level.
For example, the 2025, 2024, 2020, 2019, 2018, 2017, 2016, 2015, 2014, 2013, 2012, and 2011 models all have a capacity of 18.5 gallons. The 2023, 2022, and 2021 models have a slightly lower capacity of 18.0 gallons.
As for earlier models, the 2009 Subaru Legacy is noted to have a range depending on its trim level, while the 2008, 2007, and 2006 models have a capacity of 16.9 gallons.
Although the exact fuel tank capacity for the 2003 Subaru Legacy is not specified, the provided information on adjacent model years offers valuable insight for comparison and estimation.

Fuel gauges are inaccurate
The fuel tank capacity of the 2003 Subaru Legacy is 16.9 gallons. While the capacity of the tank is important, it is also crucial to know how many miles per gallon the car can achieve. The fuel mileage achieved by the 2003 Subaru Legacy will dictate the range of the vehicle on a full tank of fuel.
Fuel gauges in cars are not always accurate and there can be several reasons for this. The most common cause of an inaccurate fuel gauge is a faulty or malfunctioning component called the sending unit. This unit is used to measure the amount of fuel in the tank and communicate the level to the gauge on the dashboard. When driving, the sending unit rubs against a variable resistor, which can lead to wear over time. A worn sending unit can misinterpret signals and show full or empty regardless of the actual fuel level.
Corrosion and loose connections can also cause issues with the sending unit and fuel gauge. Corroded wires can stop voltage from reaching the fuel gauge, resulting in an inaccurate reading. In addition, the internal circuit in the gauge itself can fail, leading to a partially or fully inoperable gauge. The needle may get stuck between empty and half full, or half full and full.
Another reason for an inaccurate fuel gauge reading is the float in the fuel tank. This float moves up and down according to the fuel level, and the metal rod attached to it pivots in relation to the float. This movement can cause the wiper inside the variable resistor to move, altering the electric current and resulting in an inaccurate reading.
To accurately measure your miles per gallon, it is recommended to fill your tank until the pump clicks off, reset the trip odometer, and then note how many gallons it takes to refill, dividing the number of miles traveled by the number of gallons. This will give you an accurate MPG reading and help you understand your vehicle's fuel efficiency, regardless of the fuel gauge reading.

The 2005 model's fuel gauge is inaccurate, but it holds 12 gallons
The fuel tank capacity of a car is an important consideration when planning trips. The 2003 model year of the Subaru Legacy was not specified in my search results, but it is likely to have a similar fuel tank capacity to the 2005 model year, which holds 64 litres or 16.9 gallons.
The fuel gauge on the 2005 Subaru Legacy has been reported by some owners as being inaccurate, but it is important to note that the car's fuel tank capacity is 12 gallons. This information can be crucial when planning refuelling stops on long journeys, as well as understanding the overall range of the vehicle.
While the 2005 model year's fuel gauge may not always provide a precise reading, knowing the fuel tank capacity can help owners estimate their mileage and refuelling needs more accurately. It is worth noting that factors such as driving conditions (urban or highway), fuel mileage, and speed can also impact the overall range of a vehicle.
For example, if the 2005 Subaru Legacy is driven primarily in urban areas with frequent stops and starts, its fuel economy will differ from that of highway driving, where the vehicle can maintain a more consistent speed. These factors will ultimately influence the vehicle's range before refuelling is required.
Understanding the fuel tank capacity and the potential inaccuracy of the fuel gauge in the 2005 model can empower owners to make better-informed decisions about their refuelling needs and trip planning. It may also be beneficial to refer to the vehicle's trip computer or onboard diagnostics for more precise real-time fuel consumption data.
