Diesel fuel is denser and less reactive than gasoline during the refining process
The refining process for diesel fuel involves cracking long carbon chains into shorter ones, which can then be turned into diesel, bunker fuel, fuel oil, or lubricating oil. Light crude oil has more light compounds and produces a higher yield of gasoline than diesel. On the other hand, heavy crude oil has fewer light compounds and produces a lower yield of gasoline. Most American refineries use heavy crude oil, which requires additional processing to remove sulfur and other impurities.
The market demand for diesel fuel also plays a role in the refining process. Diesel is commonly used in commercial vehicles, such as trucks, ships, and trains, as well as in public transit, heavy machinery, and generators. The increase in global trade and the adoption of diesel engines have contributed to the rising demand for diesel fuel. However, diesel cars have faced EPA problems, which has impacted the demand for diesel fuel as a motor fuel.
The tax policy in the United States also influences the price of diesel fuel. Diesel fuel is subject to a higher federal excise tax than gasoline, which contributes to the higher prices of diesel fuel for consumers. Additionally, state and local taxes, as well as carbon taxes, can further increase the price of diesel fuel.
In summary, while diesel fuel is denser and less reactive than gasoline during refining, the introduction of ULSD and the associated additional refining processes have increased the cost of refining diesel fuel. Market demand, the type of crude oil used, and tax policies also play significant roles in determining the final price of diesel fuel.

Ultra-Low Sulfur Diesel (ULSD) requirements increased refining costs
The transition to Ultra-Low Sulfur Diesel (ULSD) has significantly influenced the increased costs of refining diesel fuel. ULSD, introduced between 2006 and 2010 for on-road diesel requirements, is a type of diesel fuel with substantially lowered sulfur content. This reduction in sulfur content is achieved through a refining process that removes sulfur, leading to higher refining costs.
The process of hydrotreating to achieve ultra-low sulfur levels has been particularly costly. This process involves adding complex units and expensive catalysts, which need to be regenerated or replaced periodically. The catalysts used in the hydrotreating process are crucial but extremely expensive. Additionally, producing the required hydrogen for this process is less efficient and more challenging, impacting the overall cost of refining.
The implementation of ULSD standards aimed to facilitate the use of advanced emissions control technologies, which effectively reduce harmful emissions from diesel combustion. The U.S. Environmental Protection Agency (EPA) mandated the use of ULSD in model year 2007 and newer highway diesel fuel engines equipped with advanced emission control systems. The EPA estimates that these new fuel standards will lead to a significant reduction in nitrogen oxide emissions and soot or particulate matter.
The transition to ULSD has had economic implications, with the US government estimating an increase of 5 to 25 cents per US gallon in diesel fuel prices. Additionally, the domestic refining industry has invested over $8 billion to comply with the new regulations. The increased costs associated with ULSD have contributed to diesel fuel being more expensive than unleaded fuel in the United States, a contrast to the situation before 2004.

Diesel taxes are higher than those for gasoline
Diesel fuel is denser and less reactive than gasoline, making it easier to refine from crude oil. However, Ultra-Low Sulfur Diesel (ULSD) requirements have made the refining process more complex and expensive. The need for additional refining processes and equipment has increased the cost of diesel production. Despite this, the higher taxes on diesel fuel remain a significant factor in its higher price compared to gasoline.
The higher taxation on diesel fuel is partly due to the type of vehicles and equipment that use this fuel. Diesel fuel powers not only cars but also public transit vehicles, large delivery trucks, tractors, boats, machines, generators, and other equipment. The heavier weight of these vehicles also impacts road infrastructure, leading some states to implement higher diesel taxes to compensate for road damage.
The demand for diesel fuel is another factor influencing its pricing. During economic booms, energy demand in the industry rises, and diesel costs climb faster than gasoline prices. The seasonal demand for heating oil in winter also affects diesel prices, as home heating oil and diesel fuel are both derived from petroleum distillation.
While diesel taxes are higher than gasoline taxes, it is important to note that tax rates alone do not explain the entire price differential between diesel and gasoline. The introduction of ULSD requirements and the associated refining costs have also played a significant role in making diesel more expensive. Additionally, market supply and demand dynamics, along with other factors, collectively influence the final prices of diesel and gasoline.

Diesel engines are more fuel-efficient than gasoline engines
The cost of diesel fuel versus gasoline is influenced by several factors, including refining processes, market demand, and tax policies. While diesel fuel is generally denser and less reactive during refining, requiring less processing, certain types of diesel, such as Ultra-Low Sulfur Diesel (ULSD), demand more complex and expensive refining methods.
In terms of fuel efficiency, diesel engines offer higher efficiency than gasoline engines, particularly for heavy-duty tasks and long-distance travel. According to a study by The Motley Fool, diesel engines were found to be 29% more efficient on the highway and 24% more efficient in city driving compared to gasoline engines. Diesel engines have higher torque, resulting in better fuel economy and acceleration. Additionally, diesel fuel packs more energy per gallon than gasoline, making it more economical. This is especially beneficial for highway driving and long-haul trips.
However, it's worth noting that the performance of diesel engines in city driving or for lighter tasks may not showcase a significant advantage over gasoline engines. Gasoline engines typically offer more refined performance, lower emissions, and better speed for everyday driving. Additionally, the higher cost of diesel fuel per gallon can sometimes negate the efficiency gains in miles per gallon (mpg).
While diesel engines have their strengths, it's important to consider the specific use case and driving needs. For heavy-duty or long-haul operations, diesel engines may be a more efficient choice. On the other hand, for regular driving and lighter loads, gasoline engines might be more suitable. Ultimately, the decision should be based on an assessment of individual requirements.
Furthermore, it's worth noting that the price difference between diesel and gasoline varies across different regions. For example, in many European and Asian nations, diesel is substantially cheaper than gasoline due to a higher number of diesel-powered passenger vehicles. In contrast, in the United States, market supply and demand dynamics, along with other factors, contribute to higher diesel fuel prices.
