biofuels

Most countries now use a percentage of Biofuels in their standard pump fuel and this can be easily identified by the label on the fuel pump. B (Biodiesel) is the letter used for diesel Fuel and E (Ethanol) is for petrol. The figures next to it correspond to the % in the fuel. 7% is common moving towards 8 and 10%.
Bio diesel ages up to 4 times as quick as ‘conventional’ diesel. Why ? Because fuel is hygroscopic and this means it absorbs moisture. The increased moisture (water) in the fuel system increases the risk of micro-organism, diesel Bug and contamination. At the same time, it degrades lubrication power of the fuel and may cause wear in the fuel system.
