The move to E10 (10%) ethanol was decided in Europe in a 2009 environmental legislation, all member states must supply fuel with 10% ingredients from renewable sources. Germany and France are forging ahead, where as the UK is more adept at kicking the can down the road and hanging on to the 3.5-5% level.
A tour of the internet found some interesting things;
However it is coming, Shell reformulated their premium shell super fuel recently (renamed it Nitro) and are very evasive when questioned about Ethanol content in their fuel, BP is the same when questioned abot BP ultimate premium fuel. Esso seem to be the only fuel company who state they have no ethanol in their premium fuel.
Ethanol combines with water, and drops out of the fuel, the mixture is a mild acid, so steel tanks are not imune from corrosion.
The car companies are keen to have more ethanol in petrol, the ethanol raises the ron, approx 1 point every 2.5%. This means the can design smaller engines with high compression and powerful forced induction, so meet emmision regulations easier.
The oi companies are not keen at all, at 15 % (E15) the ethanol will eat through the fuel tanks under the petrol stations, so these will all need to be replaced, at 18% it will eat through the refineries and delivery tankers.
In Brazil ethanol production takes 17 years to get a positive carbon footprint as they make biofuels from sugar cane, in the USA it takes 93 years to become carbon positive as they use grain to make biofuels.
The EU is legislated to move forward in blending more and more renewable fuel into petrol, however there is now a move to halving the amount of biofuel in petrol by 2030, as they have now realised that we will not have enough land to feed the population if huge tracts are used for biofuels.
As I said previously this is all from a tour of the internet, so treat it like opinions not facts.
Perhaps this is the last hurrah for our old bikes, enjoy them while you can.
I can imagine the 2025 hinkley Bonneville having an electric motor disguised as a pre unit 650.
