Diesel-efficient fuel is a type of diesel fuel that has a variety of additives pre-mixed into it. It is available at most ExxonMobil stations and is designed to improve fuel economy, boost engine performance, and reduce emissions. It is also advertised to be better at preventing internal and external injector deposits, which increases the overall efficiency of the fuel system. Users have observed smoother engine operation, increased mileage per gallon, and reduced engine deposits, leading to potentially lower maintenance costs in the long run. However, the actual benefits of using diesel-efficient fuel may vary depending on factors such as vehicle type, engine type, and driving style.

What You'll Learn
Diesel-efficient fuel has a positive impact on engine performance
Diesel engines have an average fuel efficiency of 20-35% more than comparable older engines, and this figure can be as high as 100-150% when compared to certain gasoline engines. This is due to the higher torque of diesel engines, which allows for better fuel efficiency and faster acceleration. Additionally, diesel engines do not require spark plugs for ignition, instead relying on compression ignition, which results in a more efficient combustion process.
The use of diesel-efficient fuel, such as Mobil Diesel Efficient fuel, can further enhance engine performance. This type of fuel is specially formulated to improve fuel efficiency, enhance engine performance, and reduce emissions compared to standard diesel fuels. Users have reported smoother engine operation, increased mileage per gallon, and reduced engine deposits, which can lead to lower maintenance costs over time. Laboratory and vehicle engine testing have shown an average fuel economy improvement of 2% when using diesel-efficient fuel.
The push for greater fuel efficiency is closely linked to the desire for increased engine durability and compliance with emission requirements. Diesel engines have historically been criticised for their emissions, but advancements in engine design and the use of biodiesel blends have made them more environmentally friendly. Innovative aftertreatment systems, such as those developed by Cummins, can convert diesel emissions into nitrogen gas and water vapour, demonstrating the potential for diesel to be a sustainable fuel option for the future.

It improves fuel efficiency
Diesel engines are widely recognised for their efficiency and reliability under heavy loads. They have higher fuel density than gasoline engines, which contributes to their higher fuel efficiency. Diesel engines have an average fuel efficiency of 20–35% more than older engines once they have been broken in.
Diesel engines are also more fuel-efficient than spark ignition engines under the same load due to their lower operating RPM, higher compression, and more energy-dense fuel. Diesel fuel is about 20% more energy dense than gasoline by volume.
One way to further improve the fuel efficiency of diesel engines is to use diesel-efficient fuel. Mobil Diesel Efficient™ fuel, for example, is a specially formulated fuel that enhances engine performance, improves fuel efficiency, and reduces emissions compared to standard diesel fuels. It helps prevent and clean up deposits to restore engine power and responsiveness, and offers fuel system corrosion protection.
Vehicle testing of Mobil Diesel Efficient™ fuel showed an average fuel economy improvement of 2%. Users have also observed smoother engine operation, increased mileage per gallon, and reduced engine deposits, leading to potentially lower maintenance costs in the long run.

It reduces emissions
Diesel fuel is refined from crude oil and produces many harmful emissions when burned. Diesel-fuelled vehicles are a major source of harmful pollutants, such as ground-level ozone and particulate matter.
To address this problem, the U.S. Environmental Protection Agency (EPA) established standards for the sulfur content of diesel fuel and emissions from new diesel engines. These standards require a major reduction in the sulfur content of diesel fuels. To meet these standards, the petroleum industry has started producing Ultra-Low-Sulfur Diesel (ULSD) fuel, which is a cleaner-burning diesel fuel that contains a maximum sulfur concentration of 15 parts per million. Using ULSD fuel and advanced exhaust emission control systems can reduce vehicle particulate emissions by up to 90% and emissions of nitrogen compounds (NOx) by 25% to 50%.
In addition to fuel standards, the EPA has also implemented regulations that require improvements in the fuel efficiency of commercial vehicles, leading to the development of a new generation of diesel-powered commercial vehicles with better fuel economy and lower emissions. These vehicles use advanced technologies to maintain near-zero emissions performance for criteria emissions particulate matter and oxides of nitrogen.
Mobil Diesel Efficient™ fuel is a branded diesel fuel with independently tested and quantified on-road fuel economy and emissions reduction claims. Third-party lab testing has demonstrated an average fuel economy improvement of 2% and a 2% reduction in CO2 tailpipe emissions in on-road applications. It helps prevent and clean up deposits, leading to improved engine power and responsiveness.
Overall, the use of diesel-efficient fuel can help reduce emissions and contribute to a better environment.

It is more expensive than gasoline
Diesel fuel is more expensive than gasoline due to a variety of factors. Firstly, diesel has a higher energy content per gallon than gasoline, which means that when priced based on energy content, diesel will be more expensive. A typical diesel range hydrocarbon contains 12 to 16 carbon atoms, while gasoline consists of hydrocarbons with around 4 to 12 carbon atoms. This higher energy content in diesel fuel contributes to its higher price.
Another factor influencing the cost of diesel is the introduction of Ultra-Low Sulfur Diesel (ULSD) standards. In the mid-2000s, the United States began phasing in ULSD to reduce harmful emissions. To meet these new standards, refineries had to invest significant amounts of money in new equipment to remove sulfur from diesel fuel. This increase in manufacturing costs contributed to the higher price of diesel fuel. Additionally, ULSD requires more refining than regular diesel, further adding to the production costs.
Taxes also play a significant role in the price difference between diesel and gasoline. The federal excise tax on diesel fuel in the United States is 24.4 cents per gallon, while the tax on gasoline is lower at 18.4 cents per gallon. This discrepancy in taxation contributes to the higher price of diesel fuel. Furthermore, several states have implemented higher diesel taxes to compensate for road damage caused by heavier trucks, which predominantly use diesel fuel.
It's worth noting that the price difference between diesel and gasoline has fluctuated over time. Until the mid-2000s, gasoline was often more expensive than diesel. However, since then, diesel prices have consistently been higher than unleaded fuel in the United States. In contrast, diesel remains significantly cheaper than gasoline in many European and Asian nations due to the higher prevalence of diesel-powered vehicles in those regions.
