So E10 is being forced into the pumps here in Ireland at the end of the year and E5 is being discontinued thereafter (Ethanol free petrol cant be bought as it is). This will likely have a detrimental effect on NSR's and other classic 2 strokes. My wife has got a doctorate in Chemistry and she said that taking ethanol out of petrol is easy. Just pour DIW (de-Ionized Water) into the petrol and shake well. The water will bond to the ethanol, as ethanol is water soluble, and the ethanol will separate from the petrol. Then drain the ethanol that is separated at the bottom and boom, apparently you have ethanol free petrol. Has anyone tried this???

I assume 2 problems.

1. The octane is now massively reduced and detonation will likely occur.

2: Detergents and other additives may be pulled out of the petrol along with the ethanol, making it even more undesirable than the original E10.

Or perhaps I'm wrong and this is a great way for us to go back to using Ethanol free petrol in our bikes.
