As someone who lives in the US, I can't tell you a direct answer to your question. With that in mind, Ethanol blends are widely available in Europe these days. Whether they are mandatory blends like the E10 in the US, I don't know. Over there you may be optional fuels. :dontknow:
In EU we have E10 at 95 Octane rating and E5 which is at 98 Octane rating. Same in Australia.
I use E10 95 Octane in both 04 1KRR and my Gen 4 ZX10R with no issues. I find low end revs throttle response to be nicer to ride than when running E5 98 Octane.
Ethanol mandatory fuel blends in normal fuel is ass-nine, I can understand it and fully support using it in Diesel Fuel and think BioDiesel a good thing but for the rest it is retarded but then so are politicians.
