This isn’t the first time I’ve been on about ethanol added to fuel. As I said here, amongst other nasty things ethanol does it absorbs moisture from the air. The moisture gets into fuel tanks and the fuel system and causes corrosion. The photo shows one of the float chambers from the carburettors on my BMW R80 motorbike. The last time I checked these chambers, about a year ago, they were clean. Because of a little incident with petrol flooding out over my shoes I have just checked them again. From what I have read about ethanol in fuel, the UK Government doesn’t think there’s a problem, despite having commissioned an independent report that concluded:
“Based on the experience of other markets where E10 (10% ethanol in fuel) has been introduced it is estimated that the majority of vehicles ten years old or older will not be compatible with E10 due to fuel system material incompatibility issues. Field experience, vehicle trials and laboratory testing have demonstrated carburettor vehicles and powered two wheelers will suffer problems due to material incompatibility, corrosion and drivability problems…”Presumably not the answer they wanted, seeing that they have done absolutely nothing about it.
The price of grain is now inextricably linked to the price of oil. See here. One fifth of the US maize crop goes to make biofuels.
