When you go to the gas station, you’ll usually just notice one type of diesel oil. However, if you’ve ever needed fuel for something else, you’ll quickly understand that there are better diesel options available depending on your needs.
What is clear diesel?
Clear diesel, also known as regular, auto, highway, or on-road diesel, is the most frequent option and is available at most gas stations in the United States. Any vehicle with a diesel motor licensed by the state for on-road use must have clear diesel. Because of its use on public roads and highways, it is legally taxable, and it has a low sulfur level that meets EPA guidelines.
The history of clear diesel in the United States.
By 2010, the Environmental Protection Agency (EPA) had mandated that all on-road diesel fuels be Ultra-Low Sulfur Diesel (ULSD). Prior to 2008, Low-Sulfur Diesel No. 2, a less environmentally friendly fuel, was utilized. ULSD is a cleaner-burning fuel than Low-Sulfur Diesel, containing 97 percent less sulfur and extending the life of motors that had previously been affected by higher sulfur levels.
Is on-road diesel always clear?
While on-road diesel has always been a clear liquid, ULSD fuels with a green or blue tint are becoming more frequent. The diesel oil is mainly visible at this point. Many oil refineries now tint their diesel with a tiny tint that changes color over time, indicating freshness.
More on this later, as the distinctions between tinted clean diesel and dyed diesel are significant.
What is red dyed diesel?
This fuel choice, often known as off-road or non-highway diesel, is only for agricultural use or vehicles that are not licensed to travel on public highways. Although red dyed diesel is not taxed in the United States, it is subject to the same pricing variables as clear diesel, such as location and fuel scarcity.
Is red dyed diesel illegal?
Off-road diesel in the United States is dyed red to distinguish between taxed and non-taxed fuel. Being caught with off-road diesel in your commercial truck is deemed tax avoidance because it is not taxed. At the very least, you’ll face hefty fines and the possibility of a felony prosecution.
Can you mix red diesel and normal diesel?
While the effects of combining fuels vary depending on the vehicle, it is also unlawful. It’s worth noting that clear and coloured diesel have similar performance with minor changes. You could potentially damage your motor only if you use a high sulfur diesel in your business vehicles, which we strongly advise against.
What is the ultra low sulfur diesel number?
Ultra-low sulfur diesel (ULSD) is diesel fuel with a sulfur content of no more than 15 parts per million (ppm). Sulfur levels in Alaska’s on-highway fuel had previously reached 3,000 parts per million.
What is diesel fuel No. 2?
The most common diesel fuel grade is #2, which is widely available at most gas stations throughout the world. This chemical composition contains the most energy components and lubricating qualities in a single blend and provides the best fuel performance currently available. The majority of scientists agree that #2 diesel fuel will safeguard injection pumps, seals, and other critical engine components.
Because it does not require the same level of refinement to create for sale, #2 is usually less expensive than #1. The disadvantage of #2 diesel is that it has a tendency to thicken into a gel when the temperature drops. During the winter, this frequently leads to sluggish starts and other issues.
Is diesel #2 identical to diesel?
The fundamental difference between Diesel #1 and Diesel #2 is the cetane rating, which, like the octane of gasoline, indicates igniting ease. It’s all about fuel efficiency, volatility, and seasonality, really.
Less wear on your engines’ batteries implies a faster and more efficient start. The increased cetane grade also helps diesel engines run more smoothly by lowering maintenance requirements.
The additional lubricants in Premium Diesel assist keep fuel system parts moving freely. The fuel pump’s and other fuel system components’ lives are extended as a result of the reduced friction.
Fuel systems can become clogged with sediments and other particles over time. While the engine is operating, detergents are injected to Diesel #1 to clean injectors and other fuel system components. Not only does a clean fuel system last longer, but it also enhances fuel efficiency and horsepower output.
Diesel #1 contains lubricants and detergents, as well as other fuel additives that improve engine performance and save downtime. Even in a well-sealed fuel system, air moisture can find its way in and cause major engine problems. Demulsifiers in premium Diesel work to separate emulsified water from the fuel so that it can be filtered out; even in a well-sealed fuel system, air moisture can find its way in and cause major engine problems. Corrosion inhibitors keep rust and corrosion at bay, while stabilizers keep blockages and buildup at bay.
Diesel #1 is sometimes known as winter diesel since it operates better in colder conditions than Diesel #2. It has a lower viscosity and does not gel when exposed to cold temperatures. Most stations sell a premium Diesel blend that is tailored to the local climate.
While premium diesel has a number of advantages, such as fewer maintenance and equipment downtime, regular diesel is less expensive at the pump, which is an essential consideration. However, total cost of ownership should take into account not only the cost savings from the fuel, but also the impact on ongoing maintenance costs. The age and size of your fleet may play a role in deciding between Diesel #1 and Diesel #2.
When deciding between Diesel #1 and Diesel #2 for your fleet, keep in mind that premium Diesel quality differs from station to station. If you choose Diesel #1, make sure your drivers get their fuel at reliable high-volume stations.

What is the difference between number one and number two diesel?
You may expect #1 diesel to be slightly more expensive than #2 diesel, as well as having less energy components. While these are the main disadvantages of this type of diesel fuel, there are also numerous advantages to consider. The most significant advantage is that it rarely has problems when utilized in cold weather, which is the polar opposite of what you’ll find with #2.
The fundamental reason why #1 diesel is helpful in cold-weather settings is that paraffin was eliminated from the chemical mix when it was created, ensuring that the chemical will always remain in liquid form when the temperature drops.
How can I tell whether my diesel has an ultra-low sulfur content?
Step 1: Make sure the pump is working properly. About two-thirds of the way up the pump, look for a label that says ULSD 15ppm.
Since the deadline for merchants to switch from selling LSD to ULSD was in 2010, all highway gas stations should have ULSD pumps. The average quantity of sulfur in the fuel, measured in parts per million, is 15ppm.
Older diesel versions register various grades, 500ppm and 5000ppm, and are only available by special order for off-road vehicles. These diesel grades are also known as farm fuel.
Step 2: Determine the cost. Aside from the fact that it will be indicated on the label, the most noticeable distinction between LSD and ULSD is the price.
ULSD is more expensive since it requires more refining and processing. ULSD will cost between $0.05 and $0.25 per gallon higher than LSD.
Step 3: Examine the odor. The additional refinement required to make ULSD decreases aromatic components, making it smell less powerful than other fuels.
This isn’t a perfect indicator, though, because each example will differ depending on refinery source.
- Inhaling gas fumes is never appropriate or safe in any situation. Inhaling solvents such as gasoline can cause dizziness, nausea, vomiting, and even brain damage. However, avoid getting too close to the fuel to smell it because the fumes will be visible in the air as you pump.
Step 4: Take a look at the color. LSD fuels must now be dyed red, and ULSD’s hue is paler than LSD’s, which appears yellow, due to the additional processing required.
Only if you’re pumping diesel into a fuel-safe container should you be concerned about the color of the fuel you’re pouring.
Step 5: Consult a member of the staff. Ask a gas station attendant if you’re still unsure whether you’re pumping ULSD into your vehicle.
Using Ultra Low Sulfur Diesel to help reduce emissions has become a nationwide strategy. Low Sulfur Diesel, an older fuel, is still used on occasion, but ULSD is more commonly found at the pump. Always double-check to make sure you’re getting the fuel you want, and if you notice any leaks while filling up, have one of YourMechanic’s licensed professionals evaluate your vehicle.
Is off-road diesel sulfur-free?
Diesel for On-Road and Off-Road Ultra Low Sulphur Diesel (ULSD) with no more than 15 ppm Sulphur is needed for both new on-road vehicles and new off-road equipment.
Is BP’s fuel sulfur-free?
BP Diesel is a sulfur-free diesel for trucks and heavy machinery. This “workhorse fuel” has lubricating additives that help diesel engines function better and save money. For storage stability and to reduce rust deposits in idle fuel systems, BP Diesel is blended.
Is biodiesel and ultra-low sulfur diesel the same thing?
Sulfur is a common ingredient in all diesel products, but what does it mean to you? Is it safe for your car? Let’s look at the various sulfur levels in diesel products and how they effect your equipment.
What is Ultra-Low Sulfur Diesel?
Since 2010, all pumps in the United States have been required to dispense ultra-low sulfur diesel (ULSD) rather than low-sulfur diesel (LSD). Furthermore, because to the lower sulfur concentration, all vehicles manufactured after 2007 are only suitable with ULSD. When compared to LSD, ULSD contains 97 percent less sulfur, making it acceptable to use with improved emission control devices in modern vehicles. These systems are harmed by higher sulfur levels. Sulfur is one of the most common contaminants in diesel exhaust, and it is not only hazardous for engines.
Is Biodiesel Ultra-Low Sulfur?
Biodiesel is a cleaner-burning fuel derived from plant or animal matter. It emits less pollutants than conventional diesel. To comply with EPA standards, it must meet the same ULSD total sulfur requirement. As a result, biodiesel has a lower sulfur content than ultra-low sulfur diesel. While there are minor differences between biodiesel and standard diesel, they do not endanger your engine when you fill up at the gas station. All diesel sold at the pump in Oregon contains at least 5% biodiesel (also known as B5).
Is Off-Road Diesel Ultra-Low Sulfur?
Off-road diesel, often known as colored diesel, contains very little sulfur. It still meets the EPA’s environmental standards and will not harm engines. However, don’t use it to fuel your highway vehicles because it’s only meant for equipment that won’t be driven on public roads. Generators, construction equipment, and other diesel-powered devices are examples of this equipment. Check out our blog on clear and red-dyed diesel to learn more about off-road diesel.
Is red diesel sulfur-free?
It’s also known as red dye, red fuel, farm fuel, off-road diesel, and cherry juice, and it’s the same ultra low sulfur diesel (ULSD) that you’ll find at your neighborhood gas station. The sole difference is that for identifying purposes, it has been coated with an oil-soluble red dye. What are the goals? Specifically, taxes. Because it isn’t meant for on-highway use, red diesel fuel is taxed far less than ordinary diesel fuel (i.e. clear or non-dyed fuel). The amount you pay for clean diesel at the pump includes state and municipal taxes, which are stated to go toward the construction, repair, and maintenance of your state’s roads.
The most common concerns diesel owners have regarding red dye are if it would harm their engine and whether they can use it on public roads. The answer to the first is that it won’t hurt anything as long as their red fuel isn’t contaminated with sulfur and is used in a contemporary engine (which calls for ULSD). The answer to the other question is no. On any public road, you are not permitted to drive a vehicle that is running on red-dye fuel. Continue reading to learn more about how red-dye diesel is created, why it’s cheaper than clear diesel, and under what conditions it’s acceptable to use.
