Here in the UK the FBHVC (Federation of British Historic Vehicle Clubs) is to test Ethanol Petrol in labority conditions for its potential damage to car engines.
It will also check the effectiveness of fuel additives designed to defeat problems associated with ethanol.
They are concerned over the bio-fuel chiefly relate to the corrosive properties of ethanol and its ability to absorb water over time,as the water is absorbed,a process known as hygroscopy takes place and the fuel becomes more acidic and thus more corrosive eating away at the component's.
Millers Oil is one of several companies that have produced neutralising additives,there technical director says " Ethanol fuel can be very aggressive to some component's on older vehicles,Aluminium,lead, copper,galvanised steel,cork,some gasket material,various rubbers and polymers are all at risk.
Modern petrol's contain 5% ethanol at present but is to be increased to 10% in 2013.
We have The Sale of Goods Act which states that items/equipment should be fit for purpose ,perhaps one of our lawyer members will inform us why it has not been use to stop this corrosive additive being used.
