What You'll Learn
#2 diesel fuel weight varies with temperature
The weight of a gallon of diesel fuel varies depending on temperature. In New England and the Mid-Atlantic States, a gallon of #2 diesel fuel weighs between 6.96 lbs and 6.91 lbs at room temperature, or between 59°F and 76°F. At colder temperatures, such as 32°F, a gallon of diesel weighs about 7.05 lbs. At very high temperatures, such as 110°F, a gallon of diesel weighs about 6.8 lbs.
These differences in weight due to temperature changes are relatively minor, but they can add up quickly for large rigs with fuel tanks that hold anywhere from 100 to 300 gallons of fuel. For example, a semi-truck with a full tank of fuel weighing about 7 lbs per gallon would carry between 875 and 2,100 pounds of fuel.
The tendency of #2 diesel to gel in cold temperatures is a well-known issue, and it often leads to hard starts and fuel gelling in single-digit and sub-zero temps. To combat this issue, truckers often blend #1 and #2 diesel, creating a winterized fuel that can withstand colder temperatures without gelling. #1 diesel is more expensive and has fewer energy components, but it rarely has problems in cold weather because it doesn't contain paraffin wax.
In warm weather, #2 diesel is generally suitable as it has the highest amount of energy components and lubricant properties. It is also the most readily available at most gas stations throughout the country.
The weight of diesel fuel is an important consideration for truck drivers as it adds to the overall weight of the truck, which must stay within legal limits. Federal law in the US, for example, limits single axles to 20,000 pounds and axles spaced between 40 and 96 inches apart (tandem axles) to 34,000 pounds.

How temperature affects the weight of #2 diesel fuel
The weight of a gallon of #2 diesel fuel varies with temperature. In New England and the Mid-Atlantic States, a gallon of #2 diesel fuel weighs between 6.96 lbs and 6.91 lbs at room temperature, or between 59°F to 76°F. At colder temperatures, such as 32°F, the weight increases to about 7.05 lbs. At very high temperatures, such as 110°F, the weight decreases to about 6.8 lbs. This is because diesel fuel expands in warmer temperatures and contracts in colder temperatures.
The impact of temperature on the weight of diesel fuel is important for both suppliers and buyers. In colder climates, suppliers may end up delivering more fuel than contracted due to the increased density of the fuel. Conversely, in hotter regions, buyers may receive less fuel than expected. To address this issue, the industry has adopted gross or net billing practices, with some states mandating one practice over the other.
The specific gravity and API gravity of diesel fuel also vary with temperature. The ASTM D287 standard measures API gravity, which is established by the American Petroleum Institute to determine the weight of petroleum relative to water. The specific gravity is inversely related to API gravity, meaning that as specific gravity increases, so does the energy level of the diesel.
Businesses that rely on diesel-powered machinery need to consider the impact of temperature on diesel fuel. In winter, diesel can undergo gelling, where wax crystals form and start to clog the filter. This can be mitigated by using winterized diesel and selecting additives that control the cold filter plugging point (CFPP). Proper coolant management is also crucial to maintaining optimal engine operation during cold weather.
Overall, temperature has a significant impact on the weight and properties of #2 diesel fuel, affecting suppliers, buyers, and businesses that depend on diesel-powered machinery. By understanding and addressing these impacts, stakeholders can make informed decisions and mitigate potential issues.

The weight of the fuel contributes to the overall weight of the vehicle, which must comply with federal weight limits. By knowing the weight of the diesel fuel and factoring it into calculations, truck drivers can ensure they stay within the legal weight range and avoid potential fines or penalties.
Additionally, the weight of #2 diesel fuel can impact fuel efficiency and vehicle performance. As diesel fuel is denser than gasoline, it provides more energy per gallon. This higher energy density makes it a preferred choice for heavy-duty engines and long-haul trips. However, the weight of the fuel also affects how much cargo a vehicle can carry, as the total weight must not exceed the legal limit. Therefore, managing the weight of diesel fuel is crucial for truck drivers and transport companies to ensure compliance, safety, and optimal fuel efficiency.

#2 diesel fuel is the most common type of diesel fuel, also known as diesel D2, diesel #2, grade 2 diesel, or road diesel. It has a density of 0.849-0.85 g/ml at 59°F (15°C), which is equivalent to a weight of 7-7.1 pounds per gallon or 3.22 kg per gallon.
To calculate the weight of #2 diesel fuel, you can multiply the volume of the fuel in gallons by its density in g/ml. For example, if you have 10 gallons of #2 diesel fuel, and the density is 0.85 g/ml, the weight would be:
Weight = 10 gallons x 0.85 g/ml = 8.5 g
You can also convert the density to pounds per gallon and then multiply by the volume in gallons. Using the same example, with a density of 7.1 pounds per gallon:
Weight = 10 gallons x 7.1 pounds/gallon = 71 pounds
It's important to note that the density of #2 diesel fuel can vary slightly with temperature and other factors, so these calculations will provide an estimate of the weight.
Additionally, the specific gravity of diesel fuel can be used to calculate its weight. The specific gravity of #2 diesel fuel is typically around 0.876 to 0.88, and this can be multiplied by the density of water in pounds per gallon at the given temperature to determine the weight of the diesel fuel.
For example, at 60°F, the density of water is 8.328 pounds/US gallon. Using a specific gravity of 0.88 for #2 diesel fuel:
Weight = Specific Gravity x Water Density = 0.88 x 8.328 pounds/US gallon = 7.33 pounds/US gallon
By using these formulas and the appropriate densities or specific gravities, you can calculate the weight of #2 diesel fuel for your specific application.
