What You'll Learn
The US will not run out of diesel fuel in 25 days
It is unlikely that the US will run out of diesel fuel in 25 days. While diesel fuel does have a finite shelf life and can begin to degrade after 28 days, the "days supply" number does not mean that the country will be left with no diesel fuel after a certain number of days.
The "days supply" number is a measurement of supply and demand, indicating how long current diesel fuel stocks would last at the current rate of consumption. This number is usually around 33 days but has dropped to a lower level of 25.9 days, according to data from the U.S. Energy Information Administration (EIA) for the week ending October 21, 2022.
While low, this number does not mean that the US will run out of diesel fuel in 25 days. It is more of a sign that refiners are struggling to keep up with demand and that there could be regional shortages and higher prices. The diesel fuel supply chain is dynamic, and suppliers will work to fill in any gaps in supply. Additionally, the US government can take action to replenish supplies, and there are alternatives to diesel fuel, such as solar and wind power, that can help meet energy needs.
Furthermore, the "days supply" number can be influenced by various factors, including the type of fuel, storage conditions, and the presence of additives or stabilizers. Proper storage conditions, such as keeping diesel fuel in a cool tank, can help prolong its lifespan. Additionally, fuel polishing and the use of additives can help maintain fuel quality and prevent degradation.
In conclusion, while the US faces a diesel fuel shortage with low stockpiles, it is unlikely that the country will run out of diesel fuel in 25 days. The "days supply" number is a dynamic measurement that can be influenced by various factors, and there are steps that can be taken to prolong the lifespan of diesel fuel and meet energy demands through alternative sources.

Diesel fuel prices are increasing
While there is no diesel fuel shortage, diesel fuel prices are increasing. As of 31 October 2022, the national average for a gallon of diesel in the US was $5.317, $1.59 higher than a year prior. The high diesel prices are due to low stockpiles of distillate fuels, which include diesel fuel and heating oil. The low stockpiles are a result of decreased imports of petroleum and petroleum products from Russia following its invasion of Ukraine, as well as increased demand for diesel fuel due to factors such as the Mississippi River drought and the demand for heating oil in the Northeast during winter.
The US Energy Information Administration (EIA) reported that as of 21 October 2022, the US had 25.9 days' worth of supply of diesel fuel. This has led to fears of an imminent diesel fuel shortage, with some media outlets claiming that the country will run out of diesel fuel by Thanksgiving. However, this is a misinterpretation of the data, as the "days supply" number is a measurement of supply and demand, indicating that refiners are struggling to keep up with demand.
The cost of crude oil, international and regional demand and supply of diesel fuel, and transportation and delivery costs all influence diesel fuel prices. Prices of transportation fuels in the US are generally more volatile than prices of other commodities, and diesel fuel prices in certain regions, such as the West Coast and California, are higher due to taxes and supply issues.
The increase in diesel fuel prices has led to concerns about the impact on consumers and the economy. Tariffs enacted by President Donald Trump have lowered demand for fuel and energy products, providing some relief to drivers. However, experts warn that any abrupt changes in the tariff situation could halt the decline in oil prices. Additionally, the Organization for Petroleum Exporting Countries and its partners (OPEC+) have announced plans to increase production, which may help to alleviate high gas prices in the future.

Diesel engines are more efficient than regular fuel
As of 21 October 2022, the U.S. had 25.9 days' worth of diesel fuel supply. However, this does not mean that the country will run out of diesel fuel anytime soon. The ""days supply" number is often misunderstood, and the high diesel prices are due to low stockpiles rather than an imminent shortage.
Diesel engines are more fuel-efficient than regular fuel engines. They are ideal for heavy-duty tasks and long distances because they offer high efficiency, more torque, and better thermal efficiency. Diesel fuel simply packs more energy in every gallon than regular fuel, making it more economical overall. Diesel engines are also more durable and last longer than regular fuel engines, with reliable operation and minimal required maintenance.
While diesel engines have a reputation for being noisier and having slower acceleration, these issues have largely been resolved by new technology. Today, the driving experience in a diesel-powered car is nearly identical to that of a gas-powered car. Additionally, diesel engines have fewer components than regular fuel engines, which means there are fewer potential parts that could malfunction.
However, there are some disadvantages to diesel engines. Diesel fuel is less readily available than regular fuel, and diesel engines tend to be more expensive. Diesel engines also produce more pollutants than regular fuel engines, with the combustion of 1 litre of diesel fuel releasing about 13% more CO2 than the same amount of gasoline.
Overall, while diesel engines have their pros and cons, they are indeed more efficient than regular fuel engines in terms of fuel economy and engine longevity.

Diesel fuel has a finite shelf life
The presence of water in diesel fuel can initiate a hydrolysis reaction, causing the fuel to break down and become susceptible to microbial growth. Microbes, such as bacteria and fungi, thrive in the presence of water and produce acids that degrade the fuel, clog filters, restrict fluid flow, corrode tanks, and damage engines. Therefore, it is crucial to minimize the exposure of diesel fuel to water to prevent premature degradation.
Additionally, the quality of diesel fuel plays a role in its shelf life. Lower-quality fuel may be more susceptible to degradation and contamination. Using expired or contaminated diesel fuel can lead to engine problems, including premature shutdown and damage. To mitigate these issues, it is recommended to use specific fuel additives and treatments designed for diesel fuel. These additives can stabilize the fuel and prevent chemical breakdown, thereby extending its shelf life.
The size of the storage tank is also a consideration. A tank that is too large may result in diesel fuel sitting for extended periods, increasing the risk of contamination. On the other hand, a tank that is too small may require frequent refilling. Therefore, it is essential to invest in a properly sized tank that suits the fuel consumption needs.
In summary, diesel fuel has a finite shelf life, and proper storage conditions, including temperature control, moisture prevention, contamination mitigation, and the use of appropriate additives, are crucial for maintaining its quality and longevity. By following these measures, users can prolong the shelf life of diesel fuel and ensure its effectiveness and safety.

Fossil fuels are a limited resource
Fossil fuels, including coal, oil, and natural gas, have been the primary energy source for economies worldwide for over 150 years. These non-renewable resources are natural substances that are not replenished at the rate at which they are consumed, resulting in a finite supply. With a steadily increasing global population and expanding economies, the demand for fossil fuels has surged, leading to a corresponding rise in greenhouse gas emissions.
Diesel fuel, a fossil fuel distillate, has been at the centre of recent concerns over potential shortages and price hikes. While the U.S. faced low stockpiles of diesel fuel in late 2022, it is important to clarify that the country was not on the brink of running out of diesel. The situation, however, underscored the challenges in keeping up with demand and the dynamic nature of the fuel supply chain.
The finite nature of fossil fuels, including diesel, underscores the urgency of transitioning to sustainable energy sources. Several renewable alternatives, such as hydropower, biomass, wind, geothermal, and solar energy, have been gaining traction and currently contribute a significant portion of electrical power in the U.S. and other countries. Nuclear energy, while carbon-free, presents challenges due to its high cost and the issue of radioactive waste disposal.
Additionally, immediate and cost-effective solutions like improving energy efficiency in various sectors, including buildings, vehicles, and industrial processes, can significantly reduce energy demand and emissions. Carbon capture and storage (CCS) technology also offers a promising avenue for mitigating the worst effects of climate change by collecting and sequestering carbon emitted by the fossil fuel sector.
As economies gradually shift towards sustainable renewable energy, it is essential to address the challenges of natural resource scarcity and the associated impact on fossil fuel consumption and greenhouse gas emissions. Strategic policy interventions, technological advancements, and market-based instruments can play pivotal roles in promoting sustainable development, mitigating climate change, and ensuring the long-term viability of critical sectors like agriculture, forestry, and fishing.

Frequently asked questions
No, the US will not run out of diesel fuel. Despite reports of a "diesel fuel shortage", this is due to a widespread misunderstanding of a government statistic. The "'days of supply' metric only measures the amount of distillate in storage compared to estimates of national demand.
The "days of supply" metric is calculated by taking the US inventory and dividing it by daily demand. A number in the high twenties to high thirties is typical for this time of year.
The "days of supply" metric is influenced by production, imports, and demand. For example, the US importing nearly 700,000 barrels per day of petroleum and petroleum products before Russia's invasion of Ukraine boosted distillate supplies. However, the invasion has since impacted global energy supplies and imports.
Low "days of supply" do not indicate imminent outages but can result in higher diesel fuel prices. Short-term regional shortages may also occur.
