In this blog, we will go over some of the causes of diesel gelling, the warning signs to look out for, and the smartest step-by-step methods to ungel.
Diesel fuel powers trucks, heavy equipment, and generators, but it could become unusable in freezing cold temperatures because of a process known as fuel gelling. Once temperatures drop too low, the paraffin wax in diesel fuel solidifies, which can clog fuel lines and filters, making it challenging or impossible for your engine to start up. If you are dealing with gelled diesel fuel, there’s no need to panic. In this blog, we will go over some of the causes of diesel gelling, the warning signs to look out for, and the smartest step-by-step methods to ungel the diesel fuel and get your fleet’s engines running again. Read on to learn more!
What’s the Cause of Diesel Gelling?
Diesel fuel contains paraffin wax, which contributes to its overall energy density and, under certain conditions, can help with lubrication and fuel efficiency. However, when exposed to cold temperatures, the wax crystallizes, forming a thick and gel-like consistency that will disrupt regular fuel flow. This gelling effect prevents diesel from passing through dangerous fuel lines and filters, leading to potential clogs and fuel starvation. Instead of causing immediate engine failure, gelling usually results in a no-start state or engine stall, especially in cold-start situations.
Use Diesel Fuel Additives
A high-quality diesel anti-gel additive or fuel treatment could help resolve fuel gelling by targeting wax crystals that form in colder temperatures. Add the recommended amount right into the fuel tank, then let it sit for around 15 to 30 minutes to take full effect before trying to start the engine. These additives are formulated to restore fuel flow by reducing wax crystal formations and unclogging filters, helping re-liquefy gelled diesel and allow it to move more freely through your fuel system.
Warm the Fuel System Up
Heat is an effective way to ungel the diesel fuel. If possible, move the vehicle into a heated garage or use a space heater to warm the fuel tank and fuel lines. Be careful while applying heat, and avoid using excessive temperatures or open flames.
Restart the Engine and Monitor the Overall Performance
Once you have treated the fuel and allowed the system to warm up, try restarting your engine. If the engine starts but runs rough, allow it to run for a few minutes to allow the fuel system to fully clear out.
