Diesel fuel is a popular choice for many vehicle owners due to its superior power and fuel economy. However, one of its main disadvantages is its poor performance in cold weather. When temperatures drop, diesel can form crystals or wax, resulting in gelling, which clogs fuel filters and fuel lines. This can lead to smoke, power loss, hard starts, or even the inability to start the engine. To prevent these issues, anti-gel additives are used, which lower the cloud point and the gelling point of the fuel. While some diesel fuels come with added anti-gel treatments, it is often unclear how much treatment has been added. Therefore, it is recommended to treat diesel fuel with anti-gel additives when temperatures are below or approaching freezing (32°F or 0°C). Additionally, rapid drops in temperature or forecasts of extremely cold weather may warrant the use of anti-gel additives as a preventative measure.

Frequently asked questions
Anti-gel should be added to diesel fuel when temperatures are expected to drop below freezing (32°F or 0°C). The colder the temperature, the more anti-gel additive should be added.
Diesel fuel that is not treated with anti-gel can form wax crystals and turn into a gel-like substance when exposed to cold temperatures. This can result in smoke, loss of power, hard starts, or the inability to start the engine.
If you are unsure whether your diesel fuel has already been treated with anti-gel, you can perform a simple test. Fill a mason jar with fuel and set it out overnight. Take another jar and put it in the freezer with a thermometer. If either jar shows cloudiness, it indicates that waxy paraffins are coming out of the fuel, which can lead to gelling.
