Diesel prices are influenced by crude oil costs
Diesel prices are influenced by a multitude of factors, including crude oil costs, refining processes, taxation, supply and demand, and global market dynamics. Here are some key reasons why diesel prices are influenced by crude oil costs:
Crude Oil Prices and Diesel Costs
Crude oil prices are a significant factor in determining diesel prices. Typically, crude oil accounts for around 50% of the end consumer prices of diesel. Therefore, fluctuations in crude oil prices directly impact the cost of diesel fuel. When crude oil prices rise, diesel prices tend to increase, and vice versa. This relationship between crude oil and diesel prices is inherent in the production process, as diesel fuel is derived from refining crude oil.
Refining Processes and Costs
The refining process for diesel fuel also plays a crucial role in influencing diesel prices. Diesel (road diesel) is a heavier petroleum distillate compared to gasoline, requiring additional treatments to remove impurities and meet environmental regulations. One of the most expensive processes is hydrodesulfurization, which reduces the sulfur content to minimize environmental impact. Ultra-Low Sulfur Diesel (ULSD), introduced between 2006 and 2010 to reduce harmful emissions, contributed to higher diesel manufacturing prices due to the extensive refining required.
Taxation Impact
Taxation policies also significantly impact diesel prices. In the United States, the federal government taxes diesel fuel at a higher rate than regular gasoline. The federal excise tax on diesel fuel is 24.4 cents per gallon, while it is only 18.4 cents per gallon for gasoline, according to sources. This disparity in taxation contributes to the higher prices of diesel fuel compared to unleaded gasoline.
Supply and Demand Dynamics
Market supply and demand factors also influence diesel prices. During an economic boom, the energy demand from industries rises, leading to an increase in diesel costs. Additionally, the demand for home heating oil, which is derived from petroleum distillation like diesel, impacts diesel prices. In winter, the demand for heating oil increases, tending to raise retail diesel prices.
Global Market Influences
Lastly, global market dynamics, including energy crises, geopolitical conflicts, and oil production decisions by organizations like OPEC, can significantly affect diesel prices. For example, the war in Ukraine and the subsequent ban on Russian oil imports by the United States impacted the global supply chain and kept diesel prices high.

Diesel engines are more efficient
While diesel fuel prices are generally higher than those of gasoline, diesel engines are more efficient. This is because diesel engines have better fuel economy than gasoline engines. In other words, diesel engines maintain power while burning less fuel. This is especially true when the engine is under load, such as when towing or hauling. The fuel efficiency of a diesel engine is a result of the longer strokes of the engine, which give the piston more time to move away from the heat, thereby lengthening the lifespan of the engine and building up power.
The higher efficiency of diesel engines is also due to their ability to withstand a higher compression ratio and cylinder pressure. This is because diesel engines have more powerful compression chambers, which require high-quality internal parts. As a result, diesel engines are designed with larger and sturdier bolts that are compatible with larger crankshafts and camshafts. This durability translates to better engine lubrication, less wear, and a longer lifespan.
Additionally, diesel engines have a smaller air-to-fuel ratio, which means that the engine burns fuel more slowly than gasoline engines. This is possible because diesel fuel is made from crude oil, while gasoline fuel is an aromatic hydrocarbon, which is harsher and more corrosive to the engine over time.
Despite the higher efficiency of diesel engines, they have not been widely adopted for passenger cars. This is due to several disadvantages, including the fact that diesel engines tend to be heavier, more expensive, and produce more smoke than gasoline engines. Diesel engines are also harder to start in cold weather and tend to be noisier and have more vibrations.

Diesel is subject to higher taxes
Diesel fuel prices are influenced by multiple factors, including regulations, refining costs, supply and demand, and taxes. While diesel is commonly associated with lower costs due to its use in strategic sectors such as freight transportation and industry, its price often exceeds that of gasoline.
One of the key factors contributing to the higher cost of diesel is taxes. In the United States, the federal government imposes a higher tax rate on diesel fuel compared to regular gasoline. The federal excise tax on diesel fuel is 24.4 cents per gallon, while the tax on gasoline is 18.4 cents per gallon. This disparity in taxation rates significantly contributes to the price difference between diesel and gasoline.
The reason for the higher taxation on diesel fuel is partly attributed to the type of vehicles that use diesel. Diesel fuel is commonly used in heavy-duty vehicles such as trucks, buses, and large commercial vehicles. These heavier trucks and commercial vehicles contribute more to road damage and infrastructure maintenance costs. As a result, several states justify their higher diesel taxes by considering the impact of these vehicles on road infrastructure.
Additionally, the demand for diesel fuel is influenced by factors such as home heating oil demand and the use of diesel in public transit vehicles, tractors, boats, machines, generators, and other equipment. During an economic boom or in the winter season, the demand for diesel fuel increases, leading to higher prices.
It is worth noting that the federal government hasn't raised the fuel or diesel tax since 1993. However, the combination of higher taxes, refining costs, and demand factors contribute to diesel fuel prices being higher than gasoline in the United States, despite diesel engines being more fuel-efficient.

Diesel refining is more expensive
Secondly, diesel fuel powers a wider range of vehicles and equipment than gasoline, including cars, public transit vehicles, delivery trucks, tractors, boats, machines, generators, and other equipment. This higher demand for diesel fuel, particularly from heavier vehicles, impacts the road infrastructure, leading to higher taxes on diesel fuel to fund maintenance and infrastructure improvements. The federal excise tax on diesel fuel in the United States, for example, is 24.4 cents per gallon, compared to 18.4 cents per gallon for gasoline.
Thirdly, external factors such as energy crises, geopolitical conflicts, and oil production decisions can significantly impact the cost of refining diesel. For example, the war in Ukraine and sanctions against Russia have disrupted the supply of oil and petroleum products, as Russia is one of the world's biggest oil producers. This reduction in supply has resulted in higher prices for diesel fuel. Additionally, U.S. refinery closures and slowdowns have further impacted the supply of diesel fuel, contributing to higher prices.
Finally, the perception that diesel is usually cheaper than gasoline due to its use in strategic sectors such as freight transportation and industry is not always accurate. Market structures and global dynamics can make diesel more expensive than gasoline in certain markets and periods. For example, in many European and Asian nations, diesel-powered passenger vehicles are more common, resulting in lower diesel prices compared to gasoline. However, in the United States, the market supply and demand factors have kept diesel prices higher than regular unleaded fuel.
