Will diesel return to normal after gelling?

While gelled fuel sounds bad, the good news is that diesel fuel will return to normal as soon as the temperature goes back up above the gel point. Pushing a vehicle into a garage and leaving it for a few hours is typically all that is required to fix the gelling problem.

What causes gelling in diesel fuel?

Gelling problems are typically caused by the effects of temperature on paraffin, a component of diesel fuel. Paraffin waxes are combustible, adding power when burned in the engine. The phases of fuel gelling include cloud point, pour point and cold-filter plug point.

When should I worry about diesel gelling?

If you could see the fuel, it will have a cloudy appearance; which is an indicator that gelling has already occurred. Other signs to look for are white smoke from the exhaust when trying to accelerate, or if you are sitting idle trying to throttle and the engine stops running.

How do I fix my diesel gelling?

How to Fix Diesel Fuel Gelling

1. Add a gallon of kerosene for every 10 gallons of diesel in the tank. Kerosene is a fuel similar to diesel; however, it has less wax and does not begin to gel until the temperature is lower than that of diesel fuel.
2. Apply heat to the fuel filter to break up the wax.

How to prevent diesel fuel gelling in the winter?

If your fueling station of choice offers diesel #1 during the winter months, this is can be a good temporary alternative, and can also be mixed with existing diesel #2 in your tank to help lower the pour point. Diesel #1 has cloud and pour points in the -40º F range, helping to prevent fuel gelling in the winter.

What happens when untreated diesel fuel gels?

Untreated diesel fuel will start to gel at just 32 degrees and be fully gelled around 15 degrees. The term “gelling” means that the diesel fuel literally turns into a hard, paste like wax. This substance obviously cannot be pumped into fuel lines, pumps or injectors, so the vehicle will not run. How to prevent fuel gelling…
