Using diesel with a low flashpoint can lead to several serious issues:

Increased Fire Hazard: A lower flashpoint means the fuel ignites more easily, raising the risk of accidental fires or explosions.

Engine Performance Issues: Diesel with a low flashpoint may ignite prematurely, causing knocking, rough operation, and reduced efficiency.

Fuel System Damage: Contaminants like gasoline can lower diesel’s flashpoint, potentially harming injectors and fuel pumps.

Safety Risks in Storage & Transport: Fuels with lower flashpoints produce more flammable vapors, increasing the danger in storage tanks and fueling stations.

Low flashpoint diesel is often caused by contamination, such as mixing with petrol, IP (illuminating paraffin) or improper fuel handling. If you suspect your diesel has a low flashpoint, testing and proper fuel management are essential to prevent damage and safety hazards.
