Diesel#1 (or 1-D) and Diesel #2 are the two types of standard diesel fuel (also known as diesel oil) (or 2-D). Diesel fuel is rated by its cetane, which indicates how easily it is to ignite and how quickly it burns, similar to how gasoline is classified by its octane. The more volatile the gasoline, the higher the cetane number. The majority of diesel cars run on fuel with a grade of 40 to 55 octane. Because all diesel OEMs define Diesel#2 for regular driving conditions, you won’t have to worry about which type to use. Because Diesel #2 is less volatile than Diesel #1 and delivers better fuel economy, truckers utilize it to transport big loads over long distances at constant speeds.
Keep in mind that API (American Petroleum Institute) classifications for oils used to lubricate diesel engines are not to be confused with diesel fuel grade ratings.
Diesel fuel is also measured by its, which refers to its thickness and flowability. Diesel fuel, like any other oil, thickens and becomes cloudier as it cools. It can turn into a gel under extreme temperatures and refuse to flow at all. Because Diesel #1 flows more easily than Diesel #2 at lower temperatures, it is more efficient. The two types of oil can be mixed, and most service stations offer diesel fuel that has been blended for the local climate.
Tip: If you’re going to drive in really cold weather, use diesel gasoline that’s rated at least 10 degrees colder than the coldest temps you’ll be facing.
For more information, consult your owner’s handbook.
Caution: Because emissions from conventional diesel gasoline have been discovered to be extremely hazardous to people and other living things, avoid inhaling the fumes while pumping it into your fuel tank until safer alternatives are developed. (The same may be said of fuel!)
Tip: Diesel gasoline supplied at truck stops is frequently less expensive than diesel fuel sold at service stations, and the fuel is also fresher. Freshness is vital since diesel fuel can readily become polluted by water vapor that condenses in fuel tanks, and truly dirty fuel can include fungus and other germs that can clog filters and fuel injectors, despite the fact that it’s rarely encountered in North America these days. Look for slimystuff on the nozzle of the fuel pump if you find yourself at a station that raises your suspicions. On a Saturday morning, when commercial trucking activity is low, try to fill up at a truck stop. The worst time to buy is on a weekday evening since cramming a little vehicle into a mob of huge rigs is difficult!
Biodiesel fuels made from agricultural waste have the potential to be a clean-burning alternative to decreasing petroleum supplies.
Rudolph HenryFord envisioned plant-based fuel as the primary fuel for transportation and cooperated with Standard Oil to develop biofuel production and distribution. Diesel’s original engine was built to run on peanut oil, and HenryFord envisioned plant-based fuel as the principal fuel for transportation. However, in the United States and Canada, the only form of biodiesel gasoline that may be used in automobiles without voiding the manufacturer’s warranty is B5, a blend of 5% biodiesel and 95% regulardiesel. Biodiesel blends of up to 30% work great in most diesel engines.
Higher mixes necessitate reprogramming the engine control unit’s (ECU) electronic fuel “mapping” system, which controls timing, fuel/air mixture, and other parameters. The reason for this is that, while a diesel engine that operates on diesel oil and a biodiesel-burning engine have no mechanical differences, biodiesel has somewhat different energy and burning characteristics than ordinary petroleum-based diesel.
Do-it-yourselfers and specialist shops in the United States have modified biodiesel vehicles to allow them to use greater biodiesel mixes and fuels made from a variety of substances. Biodiesel can be created from nearly any crop-based oil, and the news is full of stories of adapted automobiles that operate on biodiesel generated from french-fry oil and other restaurant waste, fresh-pressed cottonseed oil, and so on. However, some of these oils contain chemicals that can chew through gaskets and become rancid if stored for an extended period of time. Biodiesel can also dissolve deposits in fuel lines since it is a superior solvent than normal diesel fuel. While this may appear to be a beneficial thing, the deposits may clog gasoline filters and injectors as they flow through the fuel system. As a result, regulatory rules for biodiesel fuel’s chemical composition must be in place before it can be widely used and before automakers will allow it to be used under warranty in anything other than highly diluted levels. This is something that should happen very soon.
Diesel engines should theoretically be able to run on kerosene, some airline fuels, biodiesel blends ranging from 5% to 100%, and home heating oil, however the crucial word here is “theoretically.” Theseoils should only be used in extreme circumstances in your vehicle. These oils’ refining, filtering, and blending standards vary greatly, and they can harm your engine, violate your warranties, and cause you a lot of headaches. Look for trucking firms, food processing plants, energy plants, hospitals, and farms if you run out of gas in a rural place. These establishments frequently have diesel engines on the premises, and a good Samaritan may be kind enough to give you some. If you can’t find any diesel fuel, borrow some home heating oil or purchase Jet-A fuel at a local airport as a last resort. These alternatives are compared to rottgut whiskey by diesel mechanics: they will get you there, but they aren’t the best for your system! Only drive on these fuels for as long as it takes to reach the nearest supply of appropriate fuel.
Is there a difference between diesel fuels?
Diesel fuel is heavier than gasoline, thus it takes longer to evaporate. Diesel fuel has a higher energy density than gasoline. Despite the fact that diesel fuel is often more expensive than gasoline, most diesel engines require less of it to do the same tasks as a gasoline engine.
Is diesel fuel the same at all gas stations?
Aside from that, the chemistry and sulfur concentration of the two fuels are identical. Many diesel customers believe that diesel fuel does not differ from one pumping station to the next or from one season to the next. This brings us to the next point we’ll discuss about fuel: volatility.
Diesel fuel volatility is something that few diesel buyers will believe they have even considered. Have you ever used a winterized diesel fuel blend in your diesel equipment or car throughout the winter?
Winterized diesel fuel can be a mixture of No. 1 and No. 2 diesel fuel. The volatility of No. 1 diesel is larger than that of No. 2.
This means it can atomize faster and transition from liquid to vapor more easily, as well as having a lower gelling point. Fuel with a lower gelling point is less likely to gel or wax in colder temperatures. This is ideal for keeping your diesel car operating throughout the cold months.
Although winterized fuels are ideal for cold weather, they do have one disadvantage. The cetane rating of No. 1 diesel fuel is lower than No. 2 diesel fuel. The capacity of a fuel to combust or the combustion quality of a fuel is directly related to its cetane rating.
The higher the number, the better. Cetane ratings in diesel fuel are similar to octane values in gasoline fuel. The cetane rating of most No. 2 diesels ranges from 50 to 55.
Most No. 1 diesel fuels have a cetane rating of 40 to 50. Simply explained, one gallon of No. 1 diesel fuel has less heat energy than one gallon of No. 2 diesel fuel.
This explains why your diesel pickup gets 18 miles per gallon in the summer but just 15 miles per gallon in the winter. It will also explain why your diesel equipment is more difficult to start in the cold. No, it’s not because it’s cold outside.
If it’s a blend, the quality of winterized fuel is lower than summer fuel. Diesel fuels can also be easily winterized with additives from several suppliers without lowering the cetane levels. They might even help them.
In summary, you should ask yourself the following questions the next time you pull up to the diesel pump:
- Is this a winterized No. 1 and No. 2 blend? What proportion is it if it’s a blend?
- Is the diesel fuel I’m using ultra-low sulfur? If that’s the case, do I need to add any additives to my older fuel system?
Perhaps you’ll think twice before pulling up to the gas station and simply looking for the green nozzle. PD
What is the best type of diesel fuel?
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.
What are the three types of diesel fuel?
The most popular form of fuel is petroleum diesel, often known as fossil diesel, which is used in freight trucks, railroads, buses, and farm and construction vehicles. Petroleum diesel is also used in a large number of modern passenger automobiles. Its constituents are obtained by fractional distilling crude oil at temperatures ranging from 200 to 350 degrees Celsius under air pressure. As a result, a variety of carbon chains with between 8 and 20 carbon atoms per molecule emerges.
What is the difference between #1 and #2 diesel fuel?
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 easily. 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 production.
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.

Can I use #2 diesel in my kerosene heater?
Yes, diesel can be used in a kerosene heater. Kerosene heaters are multi-fuel heaters that can operate on a variety of fuels, including diesel. In a kerosene heater, you can even use pure vegetable oil! However, some fuels operate better in a kerosene heater than others.
Is #1 diesel fuel the same as kerosene?
If you go about on the internet, you can come across a forum question like this:
In most cases, the responses are mixed. ‘Don’t worry, you’ll be OK,’ said half of the people. “Watch out for ________,” the other half will warn.
Regular diesel is referred to as #2 diesel fuel oil, whereas kerosene is referred to as #1 diesel fuel oil. Some people believe it is similar enough to conventional (#2) diesel fuel that they may try to use it interchangeably. What would motivate them to do so, and what problems may they face?
What Makes Kerosene What It Is
The qualities of kerosene determine what happens when it is burned. Because kerosene is a lighter diesel oil than #2, it is referred to as #1 diesel. Because of its smaller weight, it has somewhat less energy roughly 135,000 BTU per gallon vs. 139,000 BTU for #2.
Aromatic compounds are often concentrated in #2 and heavier diesel fuel oils; kerosene does not have extremely significant levels of them. This is one of the reasons why #2 diesel burns drier and with less lubricity than kerosene.
The most prevalent worry is kerosene’s dry burn, which can harm gasoline pumps. In comparison to #2 diesel, kerosene has extremely little lubricity. When running on kerosene, gasoline pumps without lubricity suffer a lot of wear and may burn out. Additional wearable pieces, such as rings, gaskets, and valves, are mentioned by some. Adding some automatic transmission fluid to the kerosene is a simple cure for this. In this case, 2-cycle oil can also be used.
Some will argue that kerosene burns hotter than #2 diesel, resulting in worries about rings being burned out. Others argue that because kerosene has a lower energy value, it will not burn at a higher temperature.
The fact that kerosene has less total energy than #2 is undeniable. However, having less total energy simply means that a gallon of kerosene produces less total heat than a gallon of standard on-road diesel.
Kerosene has a lower viscosity than gasoline, which allows it to burn at a higher temperature in an engine.
Cutting Diesel with Kerosene
Kerosene can be combined with diesel fuel for a few advantages. Kerosene is particularly beneficial in the winter for modifying the cold weather handling temperatures of diesel fuel. The rule of thumb is that adding ten percent kerosene to a diesel fuel blend lowers the cold filter plugging point by five degrees. It may be more cost effective to use kerosene as a mixer than than a cold flow polymer in extremely cold climates.
To reduce emissions, kerosene and #2 are mixed together. According to the theory, kerosene “burns cleaner” than #2, resulting in lesser pollutants.
What type of diesel fuel is sold at gas stations?
Clear diesel Clear diesel is a road vehicle-grade fuel sold at gas stations around the United States. This type of fuel is intended for vehicles that travel the roads on a daily basis cars, trucks, SUVs, and so on as well as maritime vehicles.
What type of fuel do military vehicles use?
Diesel engines in trucks, railroads, boats, and barges assist in the transportation of practically all consumer goods. In public buses and school buses, diesel fuel is often used.
The majority of agriculture and construction equipment in the United States runs on diesel fuel. The building sector is likewise reliant on diesel fuel’s power. Lifting steel beams, digging foundations and trenches, drilling wells, paving roads, and moving soil securely and effectively are all tasks that diesel engines are capable of.
Diesel fuel is used in tanks and trucks by the US military because it is less flammable and explosive than other fuels. Diesel engines also have a lower chance of stalling than gasoline engines.
Diesel fuel is also utilized to create power in diesel engine generators. Diesel generators are used for backup and emergency power supply in many industrial sites, huge buildings, institutional facilities, hospitals, and electric utilities. The principal source of electricity in most Alaskan settlements is diesel generators.
