On-road diesel is either clear or somewhat green in appearance. When diesel fuel is freshly dispensed into a bottle to observe its color, refineries add a green dye, which is visible. This dye fades to yellow or darker colors as the fuel ages. Checking the fuel for a “bright” appearance, with the faint green dye being a giveaway that the diesel is new and in good condition, is part of a visual inspection to assess diesel fuel quality.
What is dyed diesel?
Diesel contains dye in almost all of it. When we talk about dyed diesel, we usually mean a red dye applied to off-road diesel. Off-road diesel is typically used for heating oil, construction fueling, agricultural use, and other off-road equipment not needed to pay fuel taxes on the highway system.
What is farm diesel?
Off-road diesel, often known as farm diesel or diesel for agricultural purposes, is diesel that is not subject to on-road fuel taxes. Diesel fuel used for agricultural purposes is tax-free. Taxes can be avoided if diesel is burned on a farm and can be tracked. In Oregon, farms are able to obtain clear diesel without paying any road fees. It is frequently coloured red to indicate that it is tax-free. Some farms may track their use of clear diesel so they can submit for Federal road taxes for off-road usage in Oregon, where P.U.C. for trucks over 26,000 GVW pay a weight mile tax instead of a per gallon state road tax.
What color is dyed diesel?
Every gallon of fuel sold in the United States contains some color. Diesel for on-road use usually has a slight green hue. This is a dye that is mixed into the fuel by either the refiner or the terminal supplier. Off-road diesels are coloured red to indicate that the fuel is tax-free and intended only for off-road use.
Why is diesel dyed?
Diesel is coloured to indicate whether or not it has paid road tax. In the United States, on-road diesel usually has a faint green hue. Off-road diesel is dyed red to indicate that it has not paid the required road taxes in all states and by the federal government.
What is off-road diesel?
Off-road diesel is diesel fuel that has been dyed red to indicate that it is tax-free and only available for off-road fuel uses such as construction fueling, equipment that is never used on a public road, agricultural use, heating oil, boiler fuel, and other non-taxed diesel fuel uses as defined by state and federal fuel tax laws. Some off-road users in Oregon can use the Oregon state tax exemption to buy on-road fuel if they have the correct papers.
Is dyed or off-road diesel flammable?
The National Fire Code classifies off-road diesel as a Class II combustible liquid. A flammable fuel has a flash point below 100 degrees Fahrenheit. The flash point of diesel ranges between 126 and 205 degrees Fahrenheit (typically assumed to be about 160 degrees F). As a result, it’s classified as a Class II combustible.
Is off-road diesel or dyed diesel high sulfur diesel?
Dyed diesel (also known as off-road diesel) contains a lot of sulfur. Diesel fuel having a sulfur level of more than 500 parts per million is known as high sulfur diesel.
Is off-road diesel or dyed diesel ultra-low sulfur diesel?
Off-road and colored diesel fuels may have ultra-low sulfur, however this is not always the case. In the United States, there has been a persistent campaign to reduce sulfur in all fuels, led by EPA regulation. Off-road construction and agricultural equipment have been required by EPA rules in recent years to have an emissions system that allows ultra-low sulfur to function without serious difficulties. As a result, today’s off-road diesel is ultra-low sulfur. If you have a tank with old dyed red diesel fuel in it, you can infer it has a sulfur concentration that is higher than ultra-low.
What is dyed ULSD fuel?
Dyed ULSD fuel is ultra-low sulfur diesel that has been dyed red to indicate that it is only intended for off-road or untaxed use. Heating oil, construction fuel, agricultural fuel, generator fuel, and other off-road uses are common uses for this type of fuel. The abbreviation “ULSD” stands for ultra-low sulfur diesel.
Is dyed diesel #1 or # 2 diesel?
Diesel that has been dyed can be either #1 or #2 diesel. Both fuels must include a red dye to prove that they are untaxed and cannot be utilized as on-road fuels.
Why does the government require diesel be dyed red?
“For two reasons, the federal government demands dyeing of untaxed diesel fuel and kerosene. To aid in the reduction of tax fraud by recognizing fuel that hasn’t paid excise taxes and to aid in the reduction of air pollution by identifying fuel that isn’t acceptable for use in highway vehicles.”
Is dyed diesel and off-road diesel kerosene?
Kerosene (which crosses as #1 diesel fuel) can be found in dyed diesel and off-road diesel, but it is not always the case. Do not mistake a dyed fuel for kerosene, which is a more uncommon fuel. Kerosene differs from #1 diesel in one way: it has been proven that it may be absorbed and taken up by a wick. All kerosene is classified as #1 diesel. Kerosene isn’t found in all #1 diesel fuels. Diesels that have been colored and off-road fuels are in the same boat. All coloured kerosene and off-road diesel are dyed. Kerosene isn’t the only coloured fuel.
Is dyed diesel and off-road diesel stove oil?
Stove oil is coloured diesel and off-road diesel. Similar to diesel, it’s usually a #1 or #2 stove oil. Stove oils, as opposed to diesel, had a slightly distinct set of specification problems in the past, which is why they were named “stove oils.” It was less precise when petroleum refineries distilled crude oils to make diesel range fuels than it is now with hydrocracking technology. The number of distillate range fuel requirements is significantly more concentrated today, thanks to both oil refinery technologies and EPA emission standards, in order to assure compliance with EPA and state rules. If your heating appliance requires stove oil, it will most likely require #1 stove oil or #1 kerosene. This product is supposed to produce less soot, making it better suited for use in a pot stove. Monitor and Toyostove thermostatically controlled direct vent heaters are the most current stove oil appliances in the United States.
Is off-road diesel bad for my truck?
It depends on the year of your truck, and we’re assuming you’re talking about red diesel fuel. To begin, it is illegal to use dyed diesel, off-road diesel, or heating oil in an on-road vehicle. If you are found in Oregon, you might face a punishment of up to $10,000, and the state is very aggressive in pursuing tax evasion. Beyond the usage of off-road fuel, which is legal. On the west coast, coloured diesel is often ultra low sulfur fuel. This means that if it’s burned in your engine, it won’t cause any problems. It may be high sulfur or low sulfur fuel, depending on the age of the colored fuel or whether it is genuinely a heating oil. If you use that fuel in a post-2007 engine with a particle trap, you’ll have major maintenance problems.
Is dyed diesel or off-road diesel heating oil?
Yes, colored diesel and off-road fuel can be used to heat your home. These days, most dyed diesel and off-road diesel is ultra-low sulfur diesel. According to the EPA and most state rules, heating oil can have a low or high sulfur concentration. So, while heating oil cannot always be colored diesel (when used for off-road machinery or agricultural purposes), dyed/off-road diesel can always be used for heating oil and meet the requirements of heating oil furnaces.
Does off-road diesel freeze?
At low temperatures, off-road diesel gels. Wax crystals form and fall out of the diesel at lower temperatures, clogging filters and gelling the fuel. Water and naturally held-in diesel will also ice up, clogging filters. Diesel gelling is the term for this phenomena.
Does off-road diesel gel in cold weather?
If it gets cold enough, all diesel fuels will gel. Wax crystals and ice accumulating in your fuel will clog filters and cause your equipment to shut down. As a rule of thumb, if you don’t treat your diesel fuel, it should work OK above 20 degrees F. If the temperature drops below 20 degrees Fahrenheit, make sure your vendor treats the fuel for winter use so it can operate at -20 degrees Fahrenheit. If you’re going to be operating in temps below that, check with your vendor to see if they’ve tested the fuel to work in temperatures below -20 degrees F.
Does off-road diesel go bad?
Off-road and dyed diesel might deteriorate with time. All ASTM-compliant diesel fuels should be safe to store for up to a year without extra treatment or testing. If you’re storing diesel for a long time, it’s a good idea to treat it with a biocide and an oxidative stabilizer to guarantee that it stays within specifications and that nothing grows in your fuel tank. Water and dirt entering the fuel through a tank vent is the worst opponent of long-term diesel storage. A tank will breathe when the temperature changes, bringing in air and moisture from the outside. Keeping your gasoline within specification means making sure there’s no water in the tank and that no outside impurities can get in.
How long can I store off-road or dyed diesel in a fuel tank?
Diesel fuel has a one-year shelf life if left untreated. You can anticipate diesel to last two to three years if it is treated with a biocide to prevent biological development in the tank. When diesel is sampled after two to three years, it loses its brightness and begins to exhibit signs of age. After three years, you’ll want to sample and test the fuel to make sure it’s up to code and safe to use.
What is the difference between off-road diesel and on-road diesel?
The significant difference between the two fuels is the amount of gasoline taxes levied. To indicate that it is both ultra-low sulfur diesel and that the on-road fuel taxes associated with using it to power a highway vehicle have been paid, all on-road diesel is transparent or greenish in color. Fuel that has been dyed has not been taxed and cannot be used to power a vehicle on a public road.
Do you pay sales tax on dyed diesel or off-road diesel in Washington state?
Yes. The sales tax is assessed if you consume colored diesel and do not pay the on-road fuel taxes in Washington state. The sales tax is not paid if you use clear fuel with road taxes connected to it. The Washington Department of Revenue has more information about Washington gasoline taxes.
What are the taxes on dyed diesel or off-road diesel in Oregon state?
Your gasoline distributor pays a modest tax (less than $.01) on the fuel they purchase at the wholesale terminal. The US EPA Superfund cleanup and the “LUST” (Leaking Underground Storage Tank Cleanup Fund) are two of the taxes. Aside from that, there are no taxes on off-road diesel fuel in Oregon (federal, state, or local municipality).
Is there a way to buy clear diesel without a road tax on it?
In Oregon, you can purchase clear fuel that is exempt from state road charges. The following are the requirements for using clear diesel in Oregon without paying state taxes:
- cars with a legal Oregon “E” plate and registered to a US government agency, an Oregon state agency, or an Oregon county or city
- Vehicles or farm tractors/equipment that are only used on the roadway inadvertently, as specified in ORS 319.520
- Unlicensed vehicles or equipment that are utilized exclusively on privately owned property
What happens if I use dyed diesel in an on-road vehicle?
If you are caught in Oregon, you might be fined $10,000 each day. We’ve seen fuel tax evaders nabbed before, so be advised that Oregon is looking for any amount of dye in an on-road vehicle’s saddle tank. You will have maintenance concerns with your vehicle’s emission system if you use low sulfur or high sulfur fuel and your vehicle has a particulate trap.
Can you use dyed diesel in a diesel pickup truck?
Only if the pickup is solely for off-roading. If you plan to utilize that truck on a public road (even to cross a street) and colored fuel is discovered in it, state regulators can (and do) levy fines of up to $10,000 per occurrence. You can use off-road diesel as the vehicle’s fuel if you have a closed facility or a large farm and are not registering the vehicle for on-road use (thus the pickup must not leave the site). Any regulator observing dyed fuel in your vehicle will assume it’s an on-road pickup if you have license plates and it’s approved for on-road use.
How does the government test if someone used dyed diesel?
Typically, regulators may take a sample from the tank or spin the gasoline filter to look for obvious dyed fuel when checking for illegal usage of dyed fuel. If the fuel is clear (or even slightly pink) and they suspect dyed fuel was used in the car, they can use a special black light to show that dyed fuel was in touch with the vehicle. They’ll beam the light on the gasoline filter, the fuel tanks, and other portions of the engine compartment that may have come into contact with the fuel. They will cite the vehicle operator if they detect even a minor trace of the red-dye used in off-road fuel in specific regions. On the internet, there are kits for filtering dye out of gasoline to eliminate the color. Those kits won’t be able to remove enough dye to keep these lights from detecting it.
Why is off road diesel illegal for pick up trucks to use?
Off-road diesel is painted red to indicate that on-road fuel taxes have not been paid or that the fuel is tax-free. Fuel taxes for on-road fuel usage are levied by the federal government and state governments to help pay for the roads we all use. Fuel taxes are deductible if you use diesel for non-road equipment, machinery, or heating/boiler uses, and the fuel is coloured to make its tax-free status obvious. In a roadside or site level inspection, regulators can also shine a black light on certain parts of a vehicle’s system to see if colored gasoline is being used illegally.
What is the difference between dyed diesel and heating oil?
What’s going on in the Pacific Northwest right now? Typically, nothing. Diesel-colored heating oil is used. To reduce the overall cost of the fuel, most petroleum distributors sell the mainstream colored diesel grade for use as heating oil. Heating oil and dyed diesel have varied ASTM requirements depending on where you acquire it. Because furnaces and boilers can manage dirtier, lower-quality fuels than off-road equipment with a particle trap, heating oil specifications have larger tolerances than diesel criteria. Although heating oil is always a diesel fuel, dyed diesel for off-road machinery may have a distinct specification. In Oregon, for example, any dyed diesel fuel used in off-road equipment must include at least 5% biodiesel or renewable diesel. Heating oil and boilers are excluded from the biofuel mandate. Heating oil, on the other hand, can be free of biodiesel, while off-road diesel for machinery cannot.
Can refrigerated trailers or “reefers use dyed diesel even if they are attached to a truck moving it on the highway?
Refrigerated trailers are, in fact, off-road vehicles. Because its engine is not pushing something along the road, the diesel-fueled refrigeration trailer is considered off-road equipment. Any ultra-low sulfur diesel fuel can be used in these trailers (dyed or clear). If you use on-road clear fuel in a refrigerated trailer and keep track and verification of the on-road fuel used in the off-road piece of equipment, you can get your fuel taxes returned. However, proof is required, so speak with your CPA or accountant.
Is all diesel fuel low sulfur?
EPA recommended ultra-low-sulfur diesel fuel as a new sulfur content standard for on-road diesel fuel marketed in the United States since October 15, 2006, with the exception of rural Alaska, which switched in 2010. It has been compulsory in California since September 1, 2006. This new rule applies to all diesel fuel, diesel fuel additives, including distillate fuels such as kerosene that are combined with diesel for on-road use. Since December 1, 2010, all highway diesel fuel in the United States has been ultra-low sulfur diesel (ULSD). In 2007, non-road diesel engine fuel was upgraded to 500 ppm sulfur, then in 2010 it was upgraded to ULSD. In 2007, railroad locomotive and marine diesel fuels were modified to 500 ppm sulfur, then in 2012, they were upgraded to ULSD. Small refiners of non-road, locomotive, and marine diesel fuel were granted exemptions, allowing 500 ppm diesel to remain in the system until 2014. All roadway, non-road, locomotive, and marine diesel fuel will be ULSD after December 1, 2014.
In model year 2007 and newer highway diesel fuel engines equipped with advanced pollution control systems that required the new fuel, the EPA mandated the use of ULSD fuel. In 2014, these sophisticated pollution control systems were mandated for marine diesel engines, and in 2015, locomotives.
The permissible sulfur content for ULSD (15 ppm) is substantially lower than the previous U.S. on-highway standard for low sulfur diesel (LSD, 500 ppm), allowing for the installation of modern emission control systems that would otherwise be harmed or made ineffective by these compounds. These devices can significantly reduce nitrogen oxide and particulate matter emissions.
Because this fuel grade is comparable to European grades, European engines will no longer need to be redesigned to cope with the greater sulfur level found in the United States. Advanced emissions control technologies, which would otherwise be harmed by sulfur, may be used in these engines. The ULSD standard was intended to enhance the availability of diesel-fueled passenger cars in the United States. Diesel-powered vehicles have been far more popular in Europe than they have been in the United States.
Additionally, the EPA has made it easier for manufacturers to shift to stricter emissions requirements by relaxing them for light-duty diesel engines from model years 2007 to 2010.
According to EPA projections, the new diesel fuel regulations will lower nitrogen oxide emissions by 2.6 million tons per year and reduce soot or particulate matter emissions by 110,000 tons per year.
On June 1, 2006, refineries in the United States were required to produce ULSD (15 ppm) for 80% of their annual output, and petroleum marketers and retailers were required to label diesel fuel, diesel fuel additives, and kerosene pumps with EPA-authorized language disclosing fuel type and sulfur content. Other restrictions, such as EPA-authorized wording on Product Transfer Documents and sulfur-content testing standards, went into effect on June 1, 2006, to prevent misfueling, contamination by higher-sulfur fuels, and liability difficulties. The EPA originally set a deadline of July 15, 2006 for distribution terminals and September 1, 2006 for retail for industry compliance to a 15 ppm sulfur level. The deadline was extended by 1.5 months on November 8, 2005, to September 1, 2006 for terminals and October 15, 2006 for retail. The extension was not granted in California, and the original schedule was maintained. The ULSD standard was in force according to the modified schedule as of December 2006, and compliance at retail outlets was reported to be in place.
What type of diesel is ultra-low sulfur?
Diesel cars manufactured in 2007 or later model years should only be filled with ultra-low sulfur diesel (ULSD). ULSD is a low-sulfur diesel fuel that burns cleaner. It has 97 percent less sulfur than low-sulfur diesel (LSD). ULSD was created to enable for the adoption of more effective pollution control systems that cut diesel emissions but are susceptible to sulfur. It’s also suitable for older diesel engines.
Whats the difference between diesel and off-road diesel?
On-road diesel, as the name implies, is authorized for use in automobiles on the road. This is the type of diesel that is sold at gas stations. On-road diesel is necessary for any vehicle licensed for use on public roads in the United States.
Off-road diesel is designed for machines that aren’t used on the road, such as tractors, construction equipment, and generators. Using off-road diesel in a vehicle that travels on roads is illegal, and using off-road diesel in an on-road vehicle can result in high fines.
Can you run off-road diesel in a pandemic?
Dyed diesel can be used if the state or federal government has proclaimed a state of emergency. It can also be used if a natural calamity has disrupted the regular fuel supply.
Is diesel #2 low sulfur?
No. 2 diesel fuel with a sulfur content of no more than 15 parts per million. It is mostly utilized in on-highway diesel engines in automobiles. A petroleum distillate that can be used as either a diesel fuel (see No. 1) or a gasoline fuel (see No.
Is diesel #2 the same as ultra low sulfur?
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 favorable 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 popular. 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 clear 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 differ 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 difference between low sulfur diesel and ultra low sulfur diesel?
In 2006, low sulfur diesel (LSD) was phased out in favor of ultra-low sulfur diesel (ULSD) as part of a larger effort to reduce particulate matter emissions from diesel engines. The project started in the European Union and eventually spread to the United States.
Since the 2007 model year, these laws have been in place for automobiles in the United States. As proposed by the Environmental Protection Agency (EPA), ultra-low sulfur diesel has replaced low sulfur diesel at the gas pump as of December 1, 2010, and pumps dispensing ULSD must be branded as such.
Ultra-low sulfur diesel is a cleaner-burning diesel fuel with a sulfur level of around 97 percent lower than low sulfur diesel. ULSD is claimed to be safe to use in older diesel engines, however there are some questions regarding this because of changes in naturally existing chemical components that improve lubricity, among other things.
The additional processing required to reduce sulfur particles in order to make ULSD removes certain lubricity agents from the gasoline, although minimum lubricity criteria are still satisfied. If necessary, lubricity additives can be utilized. The additional processing of ULSD fuel reduces the density of the fuel, lowering the energy content and resulting in somewhat reduced performance and fuel economy.
This additional processing can also alter cold flow response, which varies by season and location depending on where you reside, and can be improved by adding the appropriate additives and/or blending with No. 1 ULSD. To help you distinguish between LSD and ULSD, read the following information.
Is red diesel low sulfur?
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 only 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 may 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.
Can you mix off-road diesel with regular diesel?
No, your truck will be alright on this diesel. The main variation is in color, not in the components. It’s strictly for off-road use, as indicated by the red colour. It’s coloured red to make it visible to government officers if you’re using it illegally. Be aware that if you’re discovered driving on US highways, you could face a ticket and a hefty fine.
Off-road diesel will run your automobile if it runs on diesel. However, as previously said, if you use it illegally and are detected, you will be penalized by both the state and federal governments. Because that is sometimes the only fuel available in the event of a natural disaster, you are unlikely to be penalized.
Technically, you can, because the color is the only difference. We’ve heard of cases where someone bought a truck that ran on off-road diesel and then switched to regular diesel. In that situation, the new owner just switched to regular diesel and the vehicle performed admirably.
The distinguishing red dye is the most noticeable variation, and there may also be a difference in sulfur levels. Furthermore, because this agricultural fuel is designed for heavy machinery, it heats up quickly.
Driving until the tank is completely empty is the simplest way to get rid of the red dye. Then pour in a couple gallons of or normal diesel and let it run for a while. Repeat this process numerous times. If you want to be sure it’s gone, have your repair flush the gasoline system.
No, it isn’t possible. Except for the colour, it’s identical as on-road diesel. If you have a diesel engine, you can use farm fuel to power it. Just make sure you’re not breaking any laws when you use it.
Some people believe it is “tax-free,” but depending on the state, it may or may not be. Here’s a list of states with information on gasoline tax exemptions. When you’re permitted to use this type of fuel off-road, you’ll either pay less at the pump or get a refund on your fuel tax.
You could be charged with “Motor Fuel Tax Evasion” if you’re caught and convicted. Is it really worth it to save money on gas? Here’s what the IRS has to say about it:
“What are the Consequences?” In general, no coloured fuel should be used in highway vehicles. The Internal Revenue Code stipulates a penalty of $1,000 or $10 per gallon, whichever is larger, with payment of the tax for each violation. Additional fines may be imposed by states.”
Mixing the two types of diesel fuels is not a problem, however red diesel has a higher sulfur level than green. It’s also known as green fuel because it’s environmentally beneficial. It’s either light green or transparent in appearance.
This is subject to change. If you’re unsure, you can dip a tube in your tank and pull out a sample to see what color it is; there are also manual dipstick kits and black lights available. However, the gas does not remain in your tank; it passes through your fuel system. If you’re worried, take it to your mechanic to have the system flushed.
