Diesel Anti Bacteria (DAB)

The biggest problem is that biodiesel causes is moisture / water. Biodiesel absorbes a lot more water (up to 8 times more because biodiesel is very hygroscopic) than the EN590 diesel. Moisture in fuel is a direct source of problems.

How rises moisture in the fuel tank?

Temperature fluctuations, dark rooms, long storage (eg after winter) and a poor sealing of the fuel tank ensure that moisture may occur in fuel tanks. There is always a percentage of moisture in fuel. However, diesel can absorb max up to 0.02% water. If there is more moisture in the diesel than 0.02%, it will drop down to the lowest point of your fuel.
Excess moisture reduces the lubricity of diesel fuel and will eventually lead to bacterial growth. These bacteria must be removed before they clog the fuel filter and in the most dramatic situation; your engine will not run anymore.

Biodiesel is good for the environment, but brings a lot of problems with it for storage tanks, motors, filters, pipes etc.
