What You'll Learn
Gas station recommendations
When it comes to choosing a gas station for diesel fuel, there are several factors to consider to ensure you get the best quality fuel for your vehicle. Firstly, it is recommended to opt for busy gas stations that sell a lot of diesel, as this ensures that the fuel is replenished frequently and doesn't remain stagnant in the tanks. Stations like Chevron, Shell, and Maverik are popular choices for diesel fuel. Additionally, some users have suggested that certain stations' diesel seems to make their trucks run better, so it might be worth experimenting with different stations to find the one that suits your vehicle.
Another factor to consider is the type of diesel fuel you require. Diesel #2 is the most common type of diesel fuel available at gas stations and is suitable for trucks carrying heavy loads and long-distance driving. It has higher lubricant properties and offers better fuel performance. However, in cold weather, diesel #2 can transform into a thickened gel, making it challenging to start the engine. In such cases, diesel #1 or blended fuel, which is a combination of diesel #1 and #2, can be a better option. Some gas stations, like Sapp Bros., offer both options, allowing you to choose the right type of diesel for your vehicle.
To enhance the performance of diesel #2, you can consider using premium diesel fuel, which contains additional additives designed to improve engine performance, fuel economy, and reduce engine wear and tear. Brands like Cenex offer premium diesel fuels with enhanced additive packages, providing benefits such as improved detergency, water management, and extended filter life. However, premium diesel fuels tend to be more expensive, and the benefits may vary depending on the supplier.
For those seeking a more environmentally friendly option, biodiesel is an alternative to traditional diesel #2. Biodiesel is made from renewable resources, such as vegetable oils, animal fats, or recycled cooking oil, and can be used in many diesel engines. However, older engines may require modifications. Biodiesel blends, such as B5, B11, or B20, combine biodiesel with diesel #2 to offer the benefits of both fuels.
Lastly, diesel additives can be a valuable addition to your fuel, especially during winter. Anti-gel additives, for example, can lower the pour point of the fuel, making it easier to inject into the engine even in cold conditions. Additives can also improve ignition, enhance lubrication, and clean the fuel system, resulting in improved fuel economy and reduced engine wear. Sapp Bros. offers a range of diesel additive products to protect your engine during the winter months.

Premium vs standard
Diesel fuel is more energy-efficient than gasoline and can last longer, which means fewer trips to the gas station. Diesel #2 is the type of diesel fuel typically available at gas stations and is the least expensive option. It is used for trucks carrying heavy loads and for driving long distances at consistent speeds. Diesel #2 is also less volatile and gives better fuel economy.
However, premium diesel fuels have additional benefits that may be worth considering. Premium diesel generally has a higher cetane rating, which means it can reach higher temperatures before spontaneously combusting and is easier to ignite. Premium diesel also often contains added lubricants that help reduce friction and keep the fuel system parts moving efficiently. Additionally, premium diesel may include detergents that provide injector-cleaning capabilities, reducing the need for costly future repairs.
Some sources suggest that the benefits of premium diesel are most noticeable in performance cars, where the engine is designed to make the most of the higher-quality fuel. If you drive an ordinary mainstream car, there may not be a significant advantage to using premium diesel as your car is likely already set up to work properly using standard diesel fuel.
When choosing where to fill up with diesel #2, it is recommended to choose busier stations that sell a lot of diesel, as their fuel is likely to be replenished more frequently, ensuring fresher fuel. Additionally, staying away from gas stations that don't sell a lot of diesel is advised, as their fuel may contain water or debris.
Some of the companies that sell #2 diesel fuel include Maverik, Phillips 66, Chevron, Shell, Flying J, Sinclair, and Citgo.

Biodiesel blends
In the United States, most biodiesel is consumed in blends of B2, B5, or B20. As of 2022, biodiesel accounted for about 9% of total US biofuels production and consumption, with a production capacity of about 2.9 billion gallons per year. Biodiesel blends are becoming more common due to government incentives and requirements, such as the Renewable Fuel Standard Program and the Biodiesel Mixture Excise Tax Credit.
Some vehicle fleets use pure biodiesel (B100), but it is less commonly used as a transportation fuel due to a lack of regulatory incentives and pricing. B100 has a solvent effect, which can clean a vehicle's fuel system and release deposits accumulated from petroleum diesel use. However, this can initially clog filters, requiring frequent filter replacements when first transitioning to high-level blends.

Cetane ratings
The cetane rating, or cetane number, is a measure of combustion efficiency in diesel fuel. It is an indicator of the speed of combustion and the compression needed for ignition. The higher the cetane rating, the shorter the ignition delay, resulting in more efficient combustion. This leads to benefits such as increased fuel economy, reduced emissions, and improved power output.
The cetane number is calculated by blending cetane and isocetane in specific proportions and measuring the ignition delay. Cetane has a cetane number of 100, while isocetane has a number of 15. Once the blend is known, the cetane number is calculated as a volume-weighted average, rounded to the nearest whole number.
The Fuel Ignition Tester (FIT) is a reliable instrument for measuring the derived cetane number. It involves injecting fuel into a constant-volume combustion chamber at a temperature of approximately 575 °C. The ignition delay is calculated by measuring the time elapsed between the start of fuel injection and the start of combustion.
The cetane number plays a crucial role in determining the quality of diesel fuel. Generally, diesel engines perform well with a cetane number ranging from 48 to 50. Modern highway diesel engines often require fuel with a cetane number between 45 and 55. Regular No. 2 diesel typically has a cetane number of 40 to 42, while premium diesel fuels can have higher cetane numbers, ranging from 47 to 60 or more.
It is important to note that the cetane rating is not the only factor determining diesel fuel quality. Other measurements include energy content, density, lubricity, cold-flow properties, and sulfur content. Additionally, the price of diesel fuel is not always indicative of its cetane rating or overall quality.

Diesel additives
Diesel fuel additives are substances added to diesel fuel in small amounts to improve performance and stability. Additives can be added at three different stages: at the refinery, in the fuel distribution system, or by the end-user. While some additives are included in the fuel by the producer, others are added by the end-user as aftermarket additives.
There are several types of diesel fuel additives, each serving a specific purpose. Lubricity additives, for example, are used when diesel fuels lose their lubricity properties due to reduced sulphur content. These additives help reduce friction and maintain efficient fuel system operation. Ignition improver additives are another type used to increase the cetane number of the fuel, which influences how easily the fuel ignites and how hot it burns. Detergent additives are also important for controlling the formation of fuel deposits, which can impact fuel injection and emissions. Stability additives are added to diesel fuel to prevent degradation and the formation of sediment and insoluble gums during prolonged storage.
The use of diesel fuel additives has increased due to changing fuel demands and specifications. As fuel sulphur levels have decreased, the lubricating properties of diesel fuel have been affected, requiring the use of lubricity additives. The inclusion of biodiesel in diesel fuel blends may also require the use of additives to meet relevant specifications.
Some people choose to add aftermarket additives to their diesel fuel, especially for vehicles with specific requirements, such as aviation equipment or diesel engines in cold climates. Popular aftermarket additive brands mentioned in forums include Stanadyne, Archoil, Hotshots, and Opti-Lube. However, the effectiveness of additives is debated, with some arguing that proper maintenance of the vehicle is more important.
While this answer focuses on diesel fuel additives, it is worth noting that the user's initial query was about who sells 2 diesel fuel. In that regard, some of the gas stations mentioned in forums for selling diesel fuel include Maverik, Phillips 66, Chevron, Shell, Flying J, Sinclair, and Diamond Shamrock.
