Diesel fuel typically weighs about 7.1 pounds per gallon at room temperature (68°F or 20°C). However, the exact weight can vary based on temperature and altitude, as these factors affect the density of the fuel.
When diesel fuel is colder, it is denser and weighs more per gallon. Conversely, when the fuel is warmer, it’s less dense and weighs less per gallon. The altitude can also affect the weight of diesel fuel. At higher altitudes where air pressure is lower, diesel fuel is less dense and weighs less.
Also, it’s worth noting that diesel fuel comes in different grades, which can also affect its weight. For instance, #1 diesel fuel, which has a lower viscosity and is often used in cold weather, typically weighs less than #2 diesel fuel.
But generally, the weight of 7.1 pounds per gallon is a common estimate used for diesel fuel under standard conditions. Always check specific data from the fuel supplier for the most accurate information.

The weight of Diesel Fuel Can Change Depending on Its Temperature
Diesel fuel, like most substances, expands as it gets warmer and contracts as it cools down. This means that the density (and therefore the weight for a given volume) of diesel fuel can change with temperature. When diesel fuel is colder, it’s denser, meaning a given volume (like a gallon) of cold diesel fuel would weigh more than the same volume of warmer diesel fuel. Conversely, when diesel fuel is warmer, it’s less dense, meaning that the same volume would weigh less.
However, it’s important to note that these changes are usually quite small and might not have a significant impact in most practical situations. For precision in certain industrial applications, though, these changes can be significant and need to be accounted for.

The Factors That Affect Diesel Fuel Prices
- Crude Oil Prices: The price of crude oil is the most significant factor in the price of diesel fuel, as it is the raw material used to produce diesel. If the price of crude oil rises, the cost of producing diesel will also increase, leading to higher prices at the pump. The price of crude oil fluctuates based on supply and demand dynamics globally.
- Refining Costs: The process of refining crude oil into diesel fuel also adds to the cost. Different types of crude oil require different amounts of processing to convert them into diesel, which can affect the cost.
- Seasonal Demand: Diesel fuel demand can fluctuate with the seasons. In colder months, demand for home heating oil (which is similar to diesel) can increase, which may lead to higher diesel prices.
- Distribution and Marketing Costs: The costs associated with transporting the diesel from the refinery to the point of sale can also add to the price. This includes both transportation costs and the costs associated with running the service stations where the diesel is sold.
- Taxes: Government taxes can also have a significant impact on the price of diesel. These taxes can vary from place to place, leading to regional variations in diesel prices.
- Local Market Conditions: Finally, local market conditions such as regional supply and demand, competition among local retailers, and regional environmental regulations can all affect the price of diesel.
Remember, for the most accurate and up-to-date information on diesel prices, check the appropriate energy authority in your country or use online tools and apps that provide real-time fuel prices.

Factors Influencing the Weight of Diesel Fuel
Temperature
Explanation of how diesel fuel expands and contracts with temperature: Much like many other substances, diesel fuel expands as it gets warmer and contracts as it cools. This property is known as thermal expansion. As a result, the volume of a given amount of diesel fuel can vary with temperature.
Discussion on how colder diesel fuel is denser and weighs more, while warmer diesel fuel is less dense and weighs less: The thermal expansion of diesel fuel impacts its density and thus its weight per unit volume. When diesel fuel is colder, it’s denser, meaning that a gallon of cold diesel fuel would weigh more than a gallon of warmer diesel fuel. Conversely, when diesel fuel is warmer and expands, it becomes less dense, meaning a gallon of it would weigh less.
Diesel Fuel Grades
Description of different diesel fuel grades: Diesel fuel comes in various grades, primarily distinguished by their cetane numbers and sulfur content. The two commonly used types are #1 diesel fuel (also known as diesel #1) and #2 diesel fuel (or diesel #2). Diesel #1 is a lighter grade with lower energy content but superior cold-weather performance, while diesel #2 has higher energy content and is commonly used in warmer weather.
Comparison of weights of different diesel grades: Diesel #1, being lighter, typically weighs less than diesel #2. However, the specific weight can vary depending on temperature and other factors. It’s worth noting that despite the difference in weight, diesel #2 has higher energy content and can provide better fuel efficiency under appropriate conditions.
Altitude
Discussion on how diesel fuel density and weight change with altitude: Altitude can also affect the weight of diesel fuel. At higher altitudes, the atmospheric pressure decreases, which can reduce the density of diesel fuel. This means that a gallon of diesel fuel will weigh less at higher altitudes compared to sea levels. This is an important factor to consider, especially for applications in aviation or high-altitude locations.
Why It Is Important to Know the Weight of the Fuel
Diesel fuel, a type of distillate fuel oil, is commonly used in engines for trucks, buses, trains, boats, and in some models of cars due to its high-energy density and efficiency. One of the properties of diesel fuel that’s crucial for users to understand is its weight. At a standard room temperature of approximately 20°C (68°F), diesel fuel typically weighs around 7.1 pounds per gallon. However, this is a general estimate and the exact weight can vary slightly based on factors such as temperature and the specific grade of the diesel fuel.
