How do you keep diesel fuel from freezing?

One way to avoid diesel fuel from crystallizing (or gelling) is to use an anti-gel fuel supplement. Diesel fuel anti-gels are simply added to the fuel (just drop it in the fuel tank). Anti-gels drop the freezing point of diesel fuel so that it is less likely to freeze in cold temperatures.

Can diesel pumps freeze?

Diesel pumps can freeze up. Diesel gels at low temperatures, usually around 15 degrees if it’s untreated (using anti-gel fluids). If the fuel is treated, then there is a good chance it will work even in negative temperatures.

What temp does diesel ignite?

To ignite, the fuel must have a low flash point, but in order to avoid preignition caused by residual heat in a hot combustion chamber, the fuel must have a high autoignition temperature. Diesel fuel flash points vary between 52 and 96 °C (126 and 205 °F).
