I have to agree that there is a degree of scaremongering over this and doubtless hidden agendas, but I also have the opinion that it is possible that a higher concentration of ethanol may degrade certain things quicker or even cross a threshhold of degradation which was not the case at 5%.
I was driving my 'normal' car in France and filled up with the cheapest fuel on one occasion - then realised that that was E10 not E5. Didn't think much more about it but the car now stinks of petrol so something is clearly leaking. The car is 26 years old.
I agree....but it will defiantly effect lots of classic car and bike owners.....and obscure things like small old light aircraft that can use motor petrol....also old lawn mower outboard motors....the list goes on.....as well as lots more risk of fuel vaporisation.
Lots have plastic or fiberglass petrol tanks....its a real head acre for many 1000s
