Fuel Gelling

When living in warmer climates or traveling to colder regions, it’s important to ensure your Sno-Cat® runs smoothly by using #2 diesel or a Cummins-approved diesel additive to prevent fuel gelling.

 

Fuel gelling occurs when diesel fuel solidifies into a wax-like substance in cold temperatures, preventing the fuel from reaching the engine. This can also clog the fuel lines and filters.

Diesel fuel contains paraffin wax. As the temperature drops, the wax crystallizes and solidifies. This causes the fuel to appear cloudy, known as the “cloud point.” The wax crystals can clog the fuel filters, preventing the engine from running.

Fuel gelling typically occurs when temperatures fall below 10–15°F, with the highest risk during winter months.

Fuel gelling can prevent the engine from starting or significantly reduce its performance.

Store your vehicle above 32°F.
Add a Cummins-approved fuel additive before entering cold weather.
Use #2 diesel.
