Exploring Different Grades of Diesel Fuel Used in Industrial Generators

Before you buy an industrial diesel generator for your business, it is important to understand how these machines work. You will also need to know about the types of diesel fuel available for the generator you purchase, and which one is best to use – and when. One of the most important things you can do to keep your generator performing well is to use the right type of diesel fuel. Ready to learn more? Let’s go!

Diesel: Your Engine’s Power Source

So, just exactly how does diesel fuel a generator? Diesel is used as the generator engine’s power source during the process of internal combustion. As this process unfolds, diesel fuel is injected into the generator’s engine and ignited. This, in turn, sets in motion a series of events that create an electrical current. This current is then used to keep the lights on and businesses open during power outages or natural disasters.

Different Types Of Diesel For Generators

However, not all types of diesel fuel are alike. It is important to understand the available different grades. There are three options to choose from for industrial diesel generators: Diesel Fuel Grade #1 (DF1); Diesel Fuel Grade #2 (DF2); and a blend of the two called Winterized Diesel.

• DF1 has a lower viscosity than DF2, meaning it is thinner and flows more easily. This quality makes it more effective than DF2 in colder climates.
• DF2 is less volatile than DF1, meaning it burns more slowly. DF2 has a higher viscosity than DF1, making it less efficient to use at low temperatures but extremely effective in warmer climates.
• Winterized Diesel is a mix of the two types of diesel mentioned above and acts as a medium grade between the other two diesel fuel types.

The Pros And Cons Of Different Grades Of Diesel Fuel

In general, you do not need to know which type of diesel fuel is best for your diesel generator, because your local fuel supplier will know. Suppliers will offer you the best fuel option based on your generator type, the nature of your operation, and local weather conditions. That being said, knowing which fuel is best to use as your generator engine’s power source makes you a more informed operator.

• Advantages of DF1 – in DF1, paraffin has been removed from the chemical mixture. This means the fuel remains in a liquid form, even during cold winter months. DF1 is a good option for cold-climate operators.
• Disadvantages of DF1 – DF1 has a low energy content and is highly volatile. Operators need a higher volume of this type of diesel fuel to produce the same energy that a lesser amount of DF2 would produce. This drives the cost of this fuel type up. DF1 also has limited lubrication, due to the absence of the paraffin that has been removed.
• Advantages of DF2 – DF2 is readily available at most gas stations and easily delivered by most fuel suppliers. It is less expensive than DF1; however, it does start to gel up in low temperatures. This makes it a better option for warmer climates, rather than colder areas.
• Disadvantages of DF2 – DF2 tends to transform into a thick gel when the temperature plummets. This can lead to hard starts and other complications during the winter season.

DF2 also offers operators complete combustion, improved cold starts, less engine noise, reduced warm-up times, few misfires, and lower exhaust emissions. But based on its poor track record in colder climates, it is not the best type of diesel fuel for everyone. That’s where winterized diesel fuel comes into play.

Winterized Diesel Fuel For Optimal Performance In Cold Climates

Winterized Diesel Fuel is a type of diesel fuel. It is a combination of DF1 and DF2. The winterized mixed option offers benefits from both fuel grades, making it a workable and best option for generally cold climates or unexpected cold snaps in warmer regions. This type of diesel fuel has many benefits, including:

• Good energy content
• Effective lubricant compounds
• Reduced risk of fuel gelling at cold temperatures

Using the right fuel for your climate prevents engine clogs and ensures complete combustion. This in turn prolongs the life of your generator and ensures that it will function at peak performance when you need it most. If you are concerned about colder temperatures, ask your fuel supplier about winterized diesel fuel.

Know Your Fuel Type To Ensure Operating Efficiency

Diesel fuel is an excellent power source for generator engines. It allows operators to obtain the maximum benefits of a backup power source with a cost-effective solution. If you are confused about which type of diesel fuel is right for you, ask your supplier!  They will be happy to discuss the ins and outs of fuel grades with you so that your generator is primed and ready to go during the next power outage.
