Diesel fuel can turn into a gel-like substance when exposed to cold weather or freezing temperatures. This process, known as diesel gelling, occurs when wax crystals form in the fuel, causing issues with fuel flow and engine performance. To prevent diesel gelling, additives such as Howes Diesel Treat, Power Service Diesel 911, and Power Service Diesel Fuel Supplement +Cetane Boost are commonly used. These additives act as anti-gelling agents and fuel conditioners, improving lubrication and extending engine life. While some individuals opt for additive-free diesel, many rely on these treatments to ensure their vehicles perform optimally during cold temperatures.

What You'll Learn
Testing diesel fuel for anti-gel using a mason jar
If you're unsure whether the diesel fuel you've purchased contains a winter blend to prevent gelling, you can perform a simple test using a mason jar.
First, fill the mason jar with diesel fuel. Then, fill another mason jar with the same fuel and place it in the freezer with a thermometer. Leave both jars overnight. In the morning, check for any cloudiness in the diesel fuel. If the fuel appears cloudy, it means that waxy paraffins are coming out of the fuel, indicating that it may gel. Diesel fuel will typically cloud before it freezes.
You can also test anti-gel additives by filling multiple mason jars with diesel fuel and adding the prescribed dose of a different anti-gel additive to each jar. Place the jars in a deep freeze at -40 degrees Fahrenheit. A successful anti-gel additive should prevent the diesel fuel from clouding or freezing.
It is important to note that these tests are not entirely scientific, and results may vary depending on the fuel blend and other factors. However, they can provide a good visual representation of how diesel fuel reacts with different anti-gel additives.
Additionally, remember that anti-gel additives are designed to improve the condition of the base fuel. They lower the freezing point of diesel fuel, preventing it from turning into a gel-like consistency or solidifying in cold weather.

How to tell if diesel fuel has a winter blend
Diesel fuel is known to turn into a gel-like substance when temperatures drop, which can cause engine issues. To prevent this, diesel fuel is often blended with additives to create a winter blend that can withstand colder temperatures.
There are a few ways to tell if the diesel fuel you have purchased contains a winter blend:
- Check the price: If the price of diesel fuel has increased just before winter, it is likely that the station has started selling winter blend diesel fuel.
- Check the pump: In some cases, the pump may indicate that the diesel fuel is a winter blend. However, this is not always the case, as some stations may not explicitly advertise it.
- Test the fuel: One way to test if your diesel fuel has a winter blend is to fill a mason jar with the fuel and leave it outside overnight. If the temperature drops significantly and the fuel does not cloud or gel, it likely contains a winter blend. Alternatively, you can place a gallon of diesel fuel in a clear plastic jug and put it in a freezer set to -15°F or below. If there is no cloudiness or gelling after a few hours, it is likely a winter blend.
- Ask the station attendant: If you are unsure, you can always ask the staff at the fuel station if their diesel fuel contains a winter blend. They may be able to provide information about the specific blend and any additives used.
It is important to note that the methods mentioned above may not be scientifically accurate, but they can provide a good indication of whether your diesel fuel has a winter blend. Additionally, using a diesel fuel additive or treatment, such as Power Service Diesel 911 or Howes Diesel Treat, can help prevent gelling and improve engine performance during winter.

Using additives to prevent diesel fuel from gelling
Using additives is an effective way to prevent diesel fuel from gelling in cold temperatures. Diesel fuel gelling occurs when the fuel thickens or 'gels' in cold temperatures, hindering the engine's operations and impacting the vehicle's ability to start. This common issue in colder climates can be managed with preventive measures, including fuel additives.
There are several high-quality fuel treatments and additives available that can prevent wax from turning into crystals and subsequently, gelling. These additives can lower the pour and gel points, improving engine performance at lower temperatures. For instance, Amsoil Cold Flow significantly reduces cloudiness in diesel fuel, which indicates the presence of waxy paraffins. Other recommended products include Power Service Diesel Kleen, Howes, Stanadyne, and Power Service.
It is important to note that the amount of anti-gelling additive required depends on the temperature. The lower the temperature, the more additive should be used. It is recommended to follow the directions on the bottle for dosage instructions. Some additives, such as Winter's Edge, can assist in melting frozen fuel filters and dispersing water.
In addition to anti-gelling properties, these additives offer other benefits. For example, they can be used for lubrication, cleaning, and boosting engine performance. Some additives, like Diesel 911, are designed for emergency use to restore the flow of diesel fuel to an engine by reliquifying gelled fuel and de-icing frozen fuel filters. Diesel Winter Rescue is another emergency product that can be carried in your vehicle during winter to address gelling and icing issues.
While additives can be a helpful solution, it is worth noting that some fuel providers may have already added treatments to the diesel, depending on the location and climate. It is recommended to consult with your fuel provider to confirm the grade of diesel and its suitability for your region's weather conditions.

Testing diesel fuel for anti-gel in freezing temperatures
Untreated diesel fuel can be problematic in cold temperatures. At around 15°F or lower, it may start to gel, resulting in smoke, the loss of power, hard starts, or the inability to start the engine at all. This happens when diesel fuel mixes with cold weather or freezing temperatures, causing it to form wax crystals and turn into a gel-like substance. This can lead to unwanted downtime and potential revenue loss.
To test if diesel fuel has anti-gel properties in freezing temperatures, you can perform a simple test. Fill a mason jar with fuel and set it outside overnight. Take another jar, fill it with the same fuel, and place it in a freezer with a thermometer. Observe both jars for any signs of cloudiness. Diesel fuel will typically cloud before it freezes, and this cloudiness indicates that waxy paraffins are separating from the fuel. If there is no cloudiness, your fuel is likely fine in terms of anti-gelling at that temperature.
It is important to note that this test is not entirely scientific, and the results may vary based on the specific fuel and conditions. Additionally, different regions may have different blends of diesel fuel, with some being more prone to gelling than others. For example, summer fuel from El Paso, Texas, may perform differently in freezing temperatures than winter blends from the Northeast.
To prevent gelling in diesel fuel, various additives are available, such as Diesel Treat by Howes Products, Power Service Diesel Kleen, or K-1. These additives are designed to prevent gelling, improve lubrication, and extend the life of your engine. Some additives may also be marketed specifically for winter use, such as Diesel Fuel Supplement +Cetane Boost, which is intended for temperatures below +30°F. These additives can be added directly to the fuel tank according to the manufacturer's instructions.
