What You'll Learn
Diesel prices are influenced by crude oil costs
The price of diesel fuel is influenced by a multitude of factors, including global oil production, refining capacity, geopolitical instability, weather patterns, government policies, and taxes. However, the most significant factor affecting diesel prices is the cost of crude oil.
Crude oil prices are notoriously volatile, and even small fluctuations in the price of crude oil can significantly impact the cost of diesel fuel. From 2004 to 2023, the cost of crude oil accounted for about 50% of the monthly average U.S. retail on-highway diesel fuel prices. When crude oil prices increase, so do the prices of diesel fuel. This is because the process of refining crude oil into diesel fuel becomes more expensive. The cost of crude oil is influenced by various factors, such as production costs, global demand, and political stability. For instance, offshore drilling is generally more costly than land drilling, and political tensions in oil-producing regions, such as the Middle East, can lead to spikes in crude oil prices.
The price of diesel fuel is also impacted by the availability of refinery capacity. Refineries may need to reduce their output during periods of oversupply, which can increase the cost of refining diesel fuel. Additionally, environmental regulations may require the use of more costly processes or additives, further affecting the price of diesel fuel.
Demand for diesel fuel is another critical factor influencing its price. Diesel fuel is a significant transportation fuel, and its demand often aligns with economic trends. When demand for diesel is high, prices tend to increase due to limited supply and increased competition. Additionally, the demand for heating oil, which is similar to diesel fuel, can affect diesel fuel prices. Seasonal variations in heating oil demand during fall and winter can impact the diesel fuel market.
Distribution and transportation costs also play a role in diesel fuel prices. Diesel fuel, unlike gasoline, is less refined, making it more expensive to transport and store. The distance between the retail location and the source of supply can impact the final price, with areas farther from production sources, such as the Gulf Coast, typically facing higher diesel fuel prices.

Diesel vehicles: commercial use
Diesel fuel is widely used in commercial vehicles across various sectors, including transportation, construction, agriculture, and the military. In the United States, diesel fuel consumption in the transportation sector accounted for about 75% of total distillate consumption and about 15% of total petroleum consumption in 2022.
Commercial vehicles such as trucks, trains, boats, and barges rely on diesel engines to transport most of the products consumed. Diesel fuel is particularly suitable for commercial use due to its performance, efficiency, and safety features. For example, diesel engines are less likely to stall than gasoline-fueled engines, and diesel fuel is less flammable and explosive, making it ideal for military vehicles and equipment.
The fuel efficiency of diesel vehicles varies depending on several factors. The average truck consumes 30 to 40 litres of diesel for every 62 miles or 100 kilometres driven. Larger trucks with heavier payloads tend to consume more fuel, with some using up to 38 litres per 62 miles. Smaller trucks and light commercial vehicles, on the other hand, consume less fuel, with light commercial vehicles averaging around 9 litres per 62 miles.
To optimise fuel efficiency, commercial fleet operators can adopt fuel-efficient driving practices. Maintaining a constant speed, using cruise control, and avoiding speeding, idling, and harsh braking or acceleration can significantly reduce fuel consumption. Additionally, factors such as vehicle weight, engine speed, and terrain can impact fuel efficiency. For instance, climbing hills requires more engine speed and power, resulting in higher fuel consumption.

Diesel engine cars: small market share
The global vehicle diesel engine market was valued at $44.3 billion in 2023, with a projected growth to $54.7 billion by 2032, growing at a CAGR of 2.5% from 2024 to 2032. This growth is attributed to advancements in diesel engine technology, including the development of cleaner emissions systems and improved fuel efficiency. Despite this expansion, the market share for diesel engine cars remains relatively small compared to other vehicle types.
One reason for the limited market share of diesel engine cars is the rise in demand for electric vehicles (EVs) and the shift towards cleaner transportation options. Consumers are increasingly seeking smart, connected, and autonomous vehicles, driving innovation in the electric car market. Additionally, stringent emissions regulations worldwide have prompted the development of cleaner and more efficient diesel engines to comply with environmental standards. While these advancements address environmental concerns, the diesel engine car market share is still modest.
The diesel engine market is dominated by applications in heavy-duty vehicles, such as trucks, construction equipment, and agricultural machinery. Diesel engines are renowned for their high torque output and fuel efficiency, making them ideal for demanding tasks and heavy-duty applications. However, in the passenger car market, diesel engines have faced challenges due to emissions concerns, resulting in a smaller market presence compared to other vehicle types.
The Asia-Pacific region holds the most significant share of the global diesel engine market, driven by the rapid expansion of the automotive sector in emerging economies like China, India, and Japan. China maintains its dominant position due to its robust manufacturing base and high demand for diesel engines in heavy-duty vehicles. While the diesel engine market is expanding, the specific market share for diesel engine cars remains modest, especially with the increasing focus on electric vehicles and sustainable transportation solutions.

Diesel vs gasoline: fuel economy
When it comes to fuel economy, there are several factors to consider when comparing diesel and gasoline engines. While diesel engines typically have higher fuel efficiency than gasoline engines, the initial cost of diesel engines is significantly higher. This makes the cost of operation an essential factor in the decision-making process. For example, if you're considering a diesel truck, you would need to own it for more than seven years for it to become more cost-effective than a gasoline truck.
Diesel engines generally offer improved efficiency over gasoline engines without relying on electricity. This efficiency advantage is more pronounced in Europe, where diesel engines have nearly half the market share. In the United States, however, gasoline engines are more popular, and diesel has historically had a reputation as a "dirty fuel." Nonetheless, advancements in technology have made diesel a clean and efficient option for those seeking high-powered engines.
One key difference between diesel and gasoline engines lies in their ignition processes. Gasoline engines use spark plugs to ignite the fuel, while diesel engines employ extreme compression to generate the heat required for spontaneous ignition, known as compression ignition. This variation in ignition methods contributes to the fuel economy differences between the two types of engines.
Additionally, diesel engines tend to be more durable and last longer than gasoline engines, requiring less maintenance over their lifetime. Modern manufacturing methods have also addressed the previous weight disadvantage of diesel vehicles, making them comparable to similarly-sized gasoline vehicles. Diesel engines typically have fewer components, reducing the potential for malfunctions and resulting in overall economic savings due to fewer repair and maintenance services.
In summary, while diesel engines offer improved fuel economy and longevity, the higher initial cost of diesel vehicles may deter some buyers. The break-even point for diesel vehicles, in terms of cost, is typically several years into ownership, making long-term ownership more favourable for diesel engines. However, for short-term purchases, gasoline vehicles may be a more economical choice.
