Fuel tank capacity varies by engine and trim package
The fuel tank capacity of the Ford F-350 varies depending on the engine type and trim package. The F-350 is a heavy-duty truck used for carrying heavy loads and requires a lot of fuel for optimal performance. The fuel tank capacity can be either 26.5 US gallons or 40 gallons, depending on the vehicle's specifications.
For example, the 2021 Ford F-350's gas tank size ranges from 34.0 gallons to 48.0 gallons, depending on the trim level and model options. Similarly, the 2022, 2023, 2024, and 2025 models of the Ford F-350 also have gas tank sizes ranging between 34.0 and 48.0 gallons, depending on the trim level and model options.
The Ford F-350 with a 7.3L gas engine is specified to have a 48-gallon tank. However, it's important to note that there have been discrepancies in Ford's documentation regarding fuel tank information for different model years, so it's advisable to refer to the owner's manual or official specifications for the specific model in question.
Additionally, the choice between a gasoline and diesel engine can impact fuel efficiency. Generally, a diesel engine tends to provide better mileage than a gas engine.

Fuel efficiency is around 20 miles per gallon
The fuel efficiency of the Ford F-350 depends on a variety of factors, including the engine type, trim package, terrain, and weight of the load. According to some sources, the F-350 can achieve a fuel efficiency of around 20 miles per gallon under certain conditions.
The Ford F-350 is a heavy-duty truck designed for carrying heavy loads, and its fuel efficiency can vary depending on usage. For example, one owner of a 2008 F-350 reported achieving around 8 to 9 miles per gallon while towing a horse trailer through the mountains. In contrast, another owner of a 2004 F-350 reported achieving 12 to 13 miles per gallon with combined city and highway driving.
The engine type also plays a role in fuel efficiency. The diesel engine in the F-350 tends to provide better mileage than the gas engine. For example, one owner of a 2014 F-250 with a gas engine reported achieving 18 miles per gallon in the city and 20 miles per gallon on the highway. In comparison, diesel engines in the F-350 have been reported to deliver fuel efficiency of around 20 miles per gallon or more, depending on the load and terrain.
The trim package of the F-350 can also impact fuel efficiency. The fuel tank capacity of the F-350 ranges from 26.5 gallons to 48 gallons, depending on the trim level and model year. A larger fuel tank capacity can provide a greater range between fill-ups but may also result in slightly lower fuel efficiency.
Overall, while the Ford F-350 may not be known for exceptional fuel efficiency, it is possible to achieve around 20 miles per gallon under certain conditions, particularly with diesel engines and on the highway. However, it's important to consider the various factors that can impact fuel efficiency, such as terrain, load weight, and driving style.

Diesel engines get better mileage than gas engines
The fuel tank capacity of the Ford F-350 varies depending on the model year and trim level. For instance, the 2025 Ford F-350's fuel tank capacity ranges between 34.0 and 48.0 gallons, while the 2017 model has a 36-gallon tank. The 2019 model year Ford F-350 with a 7.3L gas engine is specified to have a 48-gallon tank.
Diesel engines are generally more fuel-efficient than similar-sized gasoline engines. They offer improved efficiency without relying on electricity, making them a popular choice for consumers seeking high-powered engines without sacrificing efficiency. Diesel fuel contains approximately 10% to 15% more energy than gasoline, allowing diesel vehicles to travel up to 20% to 35% farther on the same amount of fuel. This means that a 6-liter diesel engine can produce the same power as an 8-liter gasoline engine. As a result, diesel engines provide better fuel economy and more impressive acceleration. They are particularly favoured by those who drive long distances on highways, as their efficiency is more pronounced on such roads.
While diesel engines have a reputation for being dirty, advancements in technology have made them a clean and green option. The introduction of ultra-low sulfur diesel and biodiesel fuels, along with improved exhaust treatment, has allowed diesel engines to meet the same emissions standards as gasoline vehicles. However, it's worth noting that diesel engines are typically more expensive to fuel than gasoline engines, and certain types of diesel fuel, like black diesel and biodiesel, can negatively impact vehicle performance.
Diesel engines also offer advantages beyond fuel efficiency. They are known for their durability and longevity, requiring minimal maintenance while providing reliable operation. Additionally, improvements in engine design and the implementation of noise- and vibration-damping technologies have resulted in quieter and smoother diesel engines. Cold-weather starting has also been enhanced, making diesel engines a more convenient and versatile option for drivers.
In summary, diesel engines offer superior fuel mileage compared to gas engines, especially on highways and for long-distance driving. Their higher torque, improved fuel injection, and electronic engine control technologies contribute to their efficiency and performance. While diesel fuel prices may fluctuate and occasionally exceed gasoline prices, the overall economy of diesel engines over the vehicle's lifetime makes them a cost-effective and environmentally conscious choice.
