How to restore gelled fuel
Diesel fuel gelling occurs when the temperature drops, causing the paraffin wax in the fuel to crystallize and thicken, resulting in a gel-like consistency. This can obstruct fuel flow by clogging fuel filters and lines, blocking fuel injectors, and hindering engine operations. To restore gelled fuel, several measures can be taken:
Use Anti-Gel Additives: High-quality cold-weather diesel additives can effectively restore gelled fuel by preventing wax crystallization and improving water dispersion, lubricity, and cetane levels. It is important to follow the directions on the additive bottle, as the amount required may vary with temperature.
Diesel Winter Anti-Gel: Products like Diesel Winter Anti-Gel can reduce fuel line freeze-ups down to -40 °F. It lowers the cold filter plugging point (CFPP), preventing fuel lines and filters from clogging.
EDT+ Winter Defense: This additive from Hot Shot's Secret is an everyday treatment with anti-gel properties. It prevents the formation of clumps and allows fuel to flow freely at low temperatures.
Power Service Diesel 911: This product is designed for emergency use and can re-liquefy gelled fuel, de-ice frozen fuel filters, and remove water. It is suitable for all diesel engines.
Heat, Kerosene, and Fuel Additives: Applying heat to the fuel system, using kerosene, or adding fuel additives can help restore gelled fuel.
Consult a Professional: In cases of severe cold, professional assistance may be required. Diesel fuel suppliers like Ricochet Fuel offer tailored winter solutions, including diesel delivery with cold-weather treatments.
It is important to note that the effectiveness of these measures may depend on the severity of the gelling and the specific conditions. Preventative measures, such as using winterized diesel or adding treatments before the onset of cold weather, can also reduce the likelihood of fuel gelling.

Anti-gel additives for winter diesel
When temperatures drop, diesel fuel can gel, causing fuel flow issues and damaging engine performance. This is because cold temperatures cause the wax in diesel to gel, blocking fuel flow through the engine. Water in the fuel can also freeze, causing similar issues.
To prevent these issues, anti-gel additives can be added to diesel fuel. These additives work to prevent the fuel from gelling and protect against fuel filter icing. Anti-gel additives are especially important for Ultra Low Sulfur Diesel (ULSD) fuels, which have a higher affinity for water and can cause more potential issues in winter.
There are several anti-gel additives available on the market, including Power Service's Diesel Fuel Supplement +Cetane Boost and Howes Diesel Treat. Power Service's product is intended for use when temperatures drop below 30°F (-1.1°C) and can be used to prevent gelling and keep fuel filters from plugging with ice and wax. It is important to follow the directions on the bottle when using these products, as incorrect usage may lead to adverse effects on engine performance.
Another popular option is Howes Diesel Treat, which is North America's number one trusted anti-gel and fuel conditioner. It is effective in even the coldest climates and does not contain alcohol or harmful solvents, making it safe for use without voiding manufacturers' warranties. Diesel Treat also provides added benefits such as increased lubricity, the prevention of deposits, and the elimination of smoking and rough idling.
It is important to note that not all fuel is equal, and different diesel fuels may have different cloud points and pour points. As such, it is crucial to refer to the specific instructions and recommendations provided by the manufacturer of the anti-gel additive chosen.
