Algae and bacteria flourish in moist environments such as the fuel tank of diesel cars. Water enters the tank due to condensation and during refuelling. Fuel suppliers must mix a percentage of biodiesel with normal diesel oil. Biodiesel is hygroscopic and attracts water. Once bacteria are in the fuel tank, their numbers will constantly increase and sludge will develop. The sludge threatens the fuel supply to the engine and can damage the fuel pump and injectors. JLM additives clean and prevent algae
from growing and affecting the performance of the car.
