Only four companies have been accredited as Top Tier: Chevron, Shell, Exxon/Mobil, and Costco. To maintain the engine and emissions system working at their best, almost all car owner manuals recommend using Top Tier fuel if it is available.
Is there a number one 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.
The ignition delay on Diesel #1 is shorter.
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.
Lubricants have been added to Diesel #1.
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.
Detergents have been added to Diesel #1.
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.
Other helpful fuel additives are included in Diesel #1.
Diesel #1 contains lubricants and detergents, as well as other fuel additives that improve engine performance and save downtime. 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 result in major engine problems. Corrosion inhibitors keep rust and corrosion at bay, while stabilizers keep blockages and buildup at bay.
Diesel #1 operates well in cold weather.
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.
Diesel #2 is less expensive at the pump.
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 purpose of #1 diesel?
The type of diesel found in most petrol stations across the country and around the world is #2. This type of diesel fuel contains the most energy components and lubricating characteristics of any fuel mixture on the market, and it provides the best overall fuel performance. It’s great for safeguarding critical components of a diesel system, such as injection pumps, seals, and other components.
Another major advantage of #2 diesel is that it is generally less expensive than #1 diesel due to its ease of production. However, as we previously mentioned, you must exercise greater caution while using #2 diesel in freezing conditions. When the temperature drops, #2 thickens into a gel-like state, which can lead to hard starts, stalling, and other problems.
This is simply some basic facts to give you an idea of what #1 and #2 diesel entails. Keep in mind that in some cases, a combination of the two fuels is available. This blend, sometimes known as “winterized diesel,” has a slightly higher percentage of #1 grade and is excellent for usage in the months when utilizing #2 grade isn’t an option, but you don’t want to pay the full price for pure #1 diesel. Simply ensure that your engine is capable of handling this combination. Because some engines are only built to run on #2 diesel, extended usage of the mixture may degrade engine performance and durability.

Is kerosene the same as #1 diesel?
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 slightly less energy per gallon (135,000 BTU vs. 139,000 BTU for a gallon of #2).
Aromatic compounds are often prevalent 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.
Drier burn
The most prevalent worry is kerosene’s dry burn, which can harm fuel 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.
Hotter burn?
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.
Is it worthwhile to invest in premium diesel?
Spending money isn’t a problem for you? By minimizing friction and keeping intake valves clean, filling your automobile with premium fuel on a regular basis will help extend the life of the engine’s critical components. Additionally, certain machinery demands a bit extra; for example, because of the particular way a rotary engine runs, owners of cars like the Mazda RX-8 advised using only premium fuel and premixing some oil into the tank to keep things nice and lubricated.
Unlike gasoline engines, diesel engines do not benefit from higher octane fuel, thus premium diesel includes cleaning agents in the mix to remove sooty deposits and oil build-ups inside the engine.
Premium diesel is especially effective on older, poorly maintained ‘oil burners,’ which may have a higher-than-average carbon build-up. Using a premium diesel will wash out any soot, oil, or carbon build-up in the car’s fuel system and engine.
Should you choose premium diesel?
Using premium fuel in a brand-new diesel car will do nothing because all of the engine components are already clean and working properly. If you drive a diesel with a lot of miles, it can be worth it to fill up a tank with premium fuel every six months. This will remove any build-up in the fuel system by flushing it.
Have you recently purchased a used diesel vehicle? If you want to give your fuel system a thorough cleaning, use premium diesel next time you fill up. However, it is not always worth the extra money to fill up with premium fuel.
Which diesel is better: BP Ultimate or Shell V-Power?
There’s a lot to do with additives. In terms of both fuel economy and fuel system treatment, I consider BP Ultimate diesel to be the greatest all-around option. The optimum lubricity for the fuel injection pump is Shell V-Power diesel, however it does not achieve the same economy.
Is it possible to run straight #1 diesel?
Winter diesel fuel is a blend of grade 1 and 2 diesel. Kerosene is the principal component of grade no. 1 diesel. Meanwhile, it is free of paraffin. These two elements reduce the mix’s cloud and pour points, preventing it from gelling in cold conditions.
The ratio of no. 1 to no. 2 diesel fuels in the winter blend can vary depending on where you live. In general, it ranges from 20 to 80. Pure grade no. 1 diesel fuel may be necessary in the coldest areas.
Due to its low gelling point, pure grade no. 1 diesel fuel may appear to be a good alternative, but it is more expensive and has a lower energy content. Continuously running an engine on pure grade no. 1 diesel fuel may shorten the life of the fuel system.
Before the temperature goes below 7 degrees Celsius, you can use summer diesel fuel. After then, it’s time to convert to a winter blend.
Is diesel the same as Number 1 fuel oil?
Distillate fuel oil is a broad term for one of the petroleum fractions produced in traditional distillation processes. Diesel fuels and fuel oils are included. On-highway diesel engines, such as those in trucks and automobiles, as well as off-highway engines, such as those in train locomotives and agricultural machinery, use No. 1, No. 2, and No. 4 diesel fuel. Fuel oils with the numbers No. 1, No. 2, and No. 4 are largely utilized for space heating and electric power generation.
No. 1 Distillate: A light petroleum distillate that can be used as a diesel fuel or a fuel oil (see No. 1 Diesel Fuel). See No. 1 Fuel Oil for more information.
- No. 1 Diesel Fuel: A light distillate fuel oil that satisfies ASTM Specification D 975 criteria and has distillation temperatures of 550 degrees Fahrenheit at the 90% mark. It’s found in high-performance diesel engines like those seen in city buses and other comparable vehicles. See No. 1Distillate for more information.
- No. 1 Fuel Oil: A light distillate fuel oil that satisfies ASTM Specification D 396 and has distillation temperatures of 400 degrees Fahrenheit at the 10% recovery point and 550 degrees Fahrenheit at the 90% recovery point. It’s mostly used as a fuel source for portable outdoor stoves and warmers. See No. 1Distillate for more information.
No. 2 Distillate: A petroleum distillate that can be used as a diesel fuel or a fuel oil (see No. 2 Diesel Fuel definition). No. 2 Fuel oil is a good example.
- No. 2 Diesel Fuel: A fuel that fulfills the ASTM Specification D 975 criteria and has a distillation temperature of 640 degrees Fahrenheit at the 90% recovery point. It’s found in high-speed diesel engines like those found in locomotives, trucks, and cars. See No. 2Distillate for more information.
- No. 2 fuel oil (heating oil): A distillate fuel oil that meets ASTM Specification D 396 and has distillation temperatures of 400 degrees Fahrenheit at the 10% recovery point and 640 degrees Fahrenheit at the 90% recovery point. It’s utilized in atomizing type burners for home heating or commercial/industrial burner units with a moderate capacity. See No. 2Distillate for more information.
No. 4 Fuel is a distillate fuel oil that is manufactured by combining distillate and residual fuel oil stocks. It meets ASTM Specification D 396 or Federal Specification VV-F-815C and is widely utilized in industrial plants and commercial burner systems that lack preheating capabilities. It also contains No. 4 diesel fuel, which is suitable for low- and medium-speed diesel engines and meets ASTM Specification D 975.
What is the best time to start using Number 1 diesel?
When the overnight temperatures drop below 30 degrees F, it’s time to add No. 1 diesel with winter additives. The fuel cloud point will drop by 3 degrees F for every 10% of No. 1 diesel injected.
In the winter, what type of diesel should I use?
Winterizing your diesel fuel: a step-by-step guide As the weather gets colder, swap out your No. 2 diesel for a No. 1, which is devoid of paraffin wax and thus provides the optimum operability during the coldest months of the year.
