If you have a diesel engine, cold weather can be a real problem. Diesel fuel is partly made of paraffin, which begins to separate from the rest of the mixture at about 32 degrees Fahrenheit. This is known as the cloud point. At the gel point, which is about 15 degrees lower, so much paraffin has precipitated from the fuel it can no longer be poured—and your engine won’t run.  There are two simple options: using heat or additives.

Heating Your Engine

Truck RepairThe most straightforward approach to keeping diesel from gelling is to never let it get cold enough. However, this may be easier said than done. A warm garage or shop will keep your fuel liquid as intended, but not everyone has the means to store large diesel vehicles inside.

Using Additives

The second option for preventing diesel fuel from gelling is to add another substance that will lower its cloud and gel points. Kerosene is a common choice, and many diesel suppliers provide fuel that already has kerosene added. There are also commercially available additives that will do the job and provide other winter benefits, like removing unwanted deposits and helping your engine start more easily. These additives are a great choice to keep your vehicle running.
