How to Treat Your Diesel Fuel

close up of fuel gage

Diesel fuel has many important properties which, when left at the mercy of time and the elements, can become unstable. This potential instability puts your vehicle’s fuel systems—and your bottom line—at risk, and this means that every diesel driver or fleet manager should understand the ins and outs of diesel fuel treatments. 

Learning how to treat your diesel fuel isn’t particularly difficult, since you’ll just need to follow the instructions on the bottle and know when to add more. Naturally, we’ve laid out everything you need to know to get started.

Diesel Fuel Treatments: 101

When is Diesel Fuel Treatment Most Important?

One of the biggest risks related to diesel fuel is known as gelling. This occurs when the paraffin in your fuel starts to freeze and become solid. For this reason, it’s especially important to treat your diesel fuel with an anti-gelling additive whenever the temperature drops below 32 degrees fahrenheit, or whenever a significant drop in temperature occurs. If your diesel fleet requires fuel to be stored over the winter in Northern Chicago or Milwaukee, these stores should also be treated regularly.

Year-Round Diesel Fuel Treatment Benefits

Even when the weather isn’t working against you, using diesel fuel treatments can help you to protect your engine and improve overall performance. Some of the benefits of regular diesel fuel treatment include:

  • Improved fuel economy resulting from reduced consumption
  • Improved fuel lubricity for lower rates of wear and tear
  • Stabilized combustion temperature and velocity for smoother engine performance
  • Reduced emissions resulting from a lowered CO2 output and a cleaner tank
  • Increased reliability in cold/extreme weather conditions

Note that using too much additive is just as bad as not using any at all—if not worse—so be sure to follow whatever instructions are provided on the additive’s packaging.

Choosing Products to Treat Your Diesel Fuel

Products used to treat diesel fuel tend to cost between $15 and $50, and most are sold in 32-ounce bottles. Of course, it’s important to point out that not all diesel fuel treatments are equal. Many are designed with different purposes in mind, and there are certain properties that you should always look for when you’re shopping for new additives. Here’s a closer look at how to choose products to treat your diesel fuel:

  • There are many types of diesel fuel additives, including: options that stabilize your fuel over time, boost your cetane for improved combustion, clean your fuel injectors and engine parts, limit corrosion, and prevent gelling.
  • The best diesel fuel treatments will reduce emissions, remove water from your fuel, prevent coagulation, and improve fuel lubricity. Look for a product that advertises these properties.
  • The perfect all-in-one diesel fuel treatment does not exist, so you need to make a determination as to what qualities are most important for your needs. Many treatments will target one or two goals, and they often require unique refill intervals, so make sure to choose a product that’s convenient for you to use!
