What You'll Learn
Preventing diesel fuel from gelling
Gelling is a common issue with diesel fuel during winter or in colder climates. It occurs when the temperature of the fuel drops, causing the wax in the diesel to crystallize and solidify, which then prevents the flow to the engine or clogs fuel lines and filters. This can hinder the engine's operations and impact the vehicle's ability to start.
Use Anti-Gel Additives
Use high-quality cold-weather diesel additives or anti-gel additives to prevent the diesel fuel from thickening. These additives can lower the pour and gel points, allowing the engine to perform better at lower temperatures. The colder the temperature, the more anti-gel additive you should use. Add anti-gelling additives to your tank each time you fill up, following the instructions on the bottle.
Switch to Winterized Diesel
Use a premium winterized diesel with anti-gelling properties. Winterized fuel is specially formulated to prevent fuel gelling and reduce costly repairs. Many states mandate when stations can start selling winterized fuel blends, so be mindful of the blending of fuel types as you travel between climates.
Keep the Engine Warm
Keep your engine warm to prevent wax formation. Store your vehicle in a climate-controlled garage or heated environment. You can also place light bulbs under your vehicle to emit heat and keep the engine warm, or use a block heater to warm the engine's coolant and prevent freezing.
Routine Maintenance
Perform routine maintenance on your vehicle, especially during winter. Check your fuel system for residual deposits or moisture buildup, and periodically check your fuel filters for clogs.
Consult a Professional
In severe cold, consider consulting a diesel fuel supplier for tailored winter solutions. A proactive consultation can help ensure your vehicle is ready for the season.

How to ungel diesel fuel
Diesel fuel gelling occurs when the temperature drops and the paraffin wax in the fuel starts to crystallize and thicken, making the fuel gel-like. This can clog the entire fuel system since the fuel solidifies and loses its ability to flow. Gelling typically happens when the fuel is exposed to temperatures between 10 and 15 degrees Fahrenheit for 48 to 72 hours. The gelling process starts when the fuel hits the cloud point, which gives it a cloudy appearance.
To ungel diesel fuel, you need to warm up the fuel system. This can be done by moving the vehicle to a warmer place, such as a heated garage, or using engine block heaters. You can also add a diesel fuel anti-gel additive to the tank, which helps dissolve the gel and return the fuel to a liquid state. It is important to start using anti-gel before the temperatures drop below freezing to ensure it is flowing through the entire fuel system.
If you don't have access to a heated space, you can add a gel-melting formula to your tank. The amount of anti-gel to use depends on the temperature and the specific formula. Be sure to check the instructions on the formula you purchase. Additionally, it is recommended to change your fuel filter every winter as fuel filters can hold onto contaminants that have been filtered out of your fuel, increasing the likelihood of gelling.
If you have gelled fuel in your lines or filter, you will need to remove your fuel filters, fill them with a de-gel formula and diesel fuel, and then reinstall the filters before starting the engine.
To prevent diesel fuel gelling, you can use additives such as Hot Shot's Secret's EDT+ Winter Defense or Diesel Winter Anti-Gel. These additives change the crystal structure of the fuel, making it easier to flow at low temperatures.

Anti-gel additives
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 usually happens at temperatures of 14-15 degrees Fahrenheit, but it is recommended to take anti-gelling measures when temperatures hit 20 degrees Fahrenheit. Gelling can be prevented by keeping the fuel warm or changing its properties so it can withstand lower temperatures.
Some popular anti-gel additives include Hot Shot's Secret Diesel Winter Anti-Gel, Howes Diesel Treat, and EDT+ Winter Defense. These products are designed to improve cold starts, prevent gelling and icing, reduce fuel line freeze, boost cetane, and improve fuel economy. They are safe to use in all diesel engines and can be added to the fuel tank during each fill-up to ensure proper mixing and maximize effectiveness.
In addition to preventing gelling, diesel anti-gel additives can also provide other benefits such as improving detergency, stability, lubricity, and winter operability. They can also act as a de-icer and prevent fuel injector deposits. These additives are a crucial part of diesel maintenance and can help keep engines running smoothly in cold weather conditions.
