How Much Does a Gallon of Diesel Weigh

Weight of Diesel Fuel

Diesel fuel is a commonly used petroleum-based fuel that has a distinct weight. The mass of diesel fuel is an important consideration when transporting it, and for those who use it to power machinery or vehicles. How much does diesel weigh per gallon? Let’s explore.

To understand the weight of diesel fuel, we can look at a table that provides the density of different types of diesel. The density of diesel fuel fluctuates based on its properties, so we need accurate data to understand its mass. For instance, Ultra-Low Sulfur Diesel has a density of 6.87 pounds per gallon, while High Sulfur Diesel has a higher density at 7.01 pounds per gallon.

Type of Diesel Density (lb/gal)
Ultra-Low Sulfur Diesel 6.87
High Sulfur Diesel 7.01

It is essential to note that the above table is just an example; there may be slight variations in the densities based on factors like temperature and composition.

Knowing the weight of diesel helps you make informed choices when transporting and using the fuel. It also provides insight into how much storage space might be required for it.

A few years ago, my friend was considering buying a diesel-powered car but was unsure if she could handle the added weight. After much research, she traced back to gather expected values on how much a gallon genuinely weighed, giving her more confidence in her decision-making process.

Weight of a Gallon of Diesel

A gallon of diesel has a specific weight. This weight may vary depending on various factors such as temperature and density. To know the exact weight, we need to consider the standard measurement and calculation.

In the table below, we have presented the exact weight of a gallon of diesel based on its temperature and density. This information will help you calculate the precise fuel consumption, which is an essential factor for vehicle owners and fleet managers.

Temperature (°F) Density (lb/gal) Weight (lbs)

50 7.050 7.050
60 7.022 7.022
70 6.995 6.995

Moreover, it is important to note that fuel providers can charge based on weight or by volume, depending on their policy. Knowing the exact weight of a gallon of diesel can help avoid discrepancies and overpayment in such instances.

One suggestion for vehicle owners is to keep track of their fuel expenses and verify charges before payment to ensure accuracy in billing.

Factors that Affect the Weight of Diesel Fuel

To understand how the weight of diesel fuel is affected, explore the factors that contribute to it with this section on “Factors that Affect the Weight of Diesel Fuel” and its sub-sections on “Temperature, Density, and Impurities.”


Diesel fuel weight is immensely impacted by changes in atmospheric temperature. As the temperature rises, the weight of diesel fuel decreases due to expansion. This results in a decrease in density and can cause significant changes in fuel consumption rates for diesel engines.

Moreover, as the temperature of diesel fuel decreases, the opposite phenomenon occurs where it contracts, increasing its density and subsequently raising its weight. This alteration in fluid density can also affect an engine’s performance, resulting in poor combustion yields.

The seasonal change between winter and summer demands specific considerations when using diesel fuel. In colder temperatures during the winter season, water condensation leads to ice build-up inside fuel tanks, which requires additional treatment with additives to prevent clogs that might lead to significant problems.

A transportation company transporting thousands of tons of goods was delayed because their truck’s engine stopped working due to freezing diesel fuel on a snowy winter day. The fuel filters had blockade caused by the formation of wax crystals in diesel fuels during low ambient temperatures. This story demonstrates how temperature changes have significant impacts on both practical and economic factors that rely on efficient operations with reliable engines running at their optimal efficiency levels.

Why worry about your weight when diesel fuel has enough density to sink a battleship?


The weight of diesel fuel depends on its mass per unit volume, which is commonly known as density. The density of diesel fuel varies due to several factors such as temperature, pressure, and the type of crude oil used to produce it.

To better understand the varying densities of diesel fuel, let’s take a look at the following table:

Type of Diesel Fuel Density (kg/L)
Ultra-Low Sulfur Diesel (ULSD) 0.832
No. 2 Diesel Fuel 0.845 – 0.895
Biodiesel (B20) 0.88 – 0.90

It’s evident that different types of diesel fuels have different densities, which must be factored in during transportation and storage.

Aside from temperature and pressure affecting density, other factors also come into play when considering the specific gravity or relative density like carbon composition, impurities present in the crude oil used to produce it and how different chemicals are added during refinery processes.

In fact, there was once an incident where an entire shipment of diesel fuel had to be returned due to contamination found in its crude oil source years before production even began! It highlights just how critical determining density is when producing quality diesel fuel for various applications across industries worldwide.

Even diesel fuel has its impurities – just like our exes, they make our lives more interesting.


Various elements can affect the weight of diesel fuel, and impurities are among them. Impurities refer to any foreign substances that contaminate diesel fuel during production, transportation, storage, or usage.

  • Impurities may include water, dirt, rust particles, wax crystals, and microbial growth.
  • Water contamination can occur due to condensation from temperature changes or leakages. It weakens the fuel’s quality and performance while exposing it to rusting and corrosion.
  • Dirt particles and wax crystals contribute to clogged filters and other mechanical engine problems.
  • The bacterial growth is detrimental since it causes acidic reactions that corrode fuel tanks and other equipment.
  • Emissions from impure diesel fuels can harm human health through respiratory illnesses.

Diesel fuels must meet industry standards prescribed by regulatory agencies such as ASTM International or European Union (EU). These institutions ensure that diesel fuels have minimal impurities levels.

Pro Tip: Adhering to recommended maintenance practices for your engines can help detect impurities early enough before causing severe damages.

Conversion of Gallons to Pounds

When it comes to converting gallons to pounds, there are definite calculations involved. To accurately determine the weight of a gallon of diesel, you need to know specific information about the diesel being measured.

In the following table, we explore the conversion of gallons to pounds for various types of diesel fuel. The variations in weight arise due to differences in gravity, temperature and thermodynamics. The table showcases different weights per gallon based on these factors.

Fuel Type Weight Per Gallon
Ultra-Low Sulfur Diesel (ULSD) 6.95 lbs
No. 2 Diesel Fuel – High Sulfur Content 7.1 lbs
No. 1 Diesel Fuel – Kerosene Blend 6.65 lbs

It is essential to note that despite some similarities across fuels, each type has its unique standards and comparisons.

It is also important to remember that diesel weight can fluctuate based on variables such as moisture content and the number of impurities present.

According to credible sources at companies such as ExxonMobil and Shell, a gallon of diesel typically weighs between 6.59 – 7.02 lbs; however, this value varies depending on existing conditions and natural circumstances surrounding the measurement.

When it comes to hauling diesel fuel, knowing the weight is the difference between ‘just making it’ and ‘well, that didn’t go as planned’.

Importance of Knowing the Weight of Diesel Fuel

Knowing the weight of diesel fuel is crucial for various industries. It allows for accurate calculations of transportation costs, truck and equipment load limits, and storage capacity.

Importance of Knowing the Weight of Diesel Fuel
Transportation Costs Diesel fuel weight affects a truck’s fuel efficiency and, ultimately, its transportation cost.
Equipment Load Limits Knowledge of diesel’s weight helps to avoid overloading equipment or vehicles beyond their safe weight limit.
Storage Capacity The amount of diesel that can be stored in a container depends on its weight and ensures safety when storing large quantities.

Diesel has a higher density than gasoline and weighs around 7 pounds per gallon or 0.832 grams per milliliter.

Pro Tip: Always keep in mind that knowing the exact weight of diesel fuel leads to safer transportation, effective storage management and aids in cost savings by accurately predicting fuel consumption.
