For the sceptics I have found that E10 does go "stale" . The ethanol absorbs water which does not help with combustion. My experience is common among air-head BMW motor cycle owners. The foam floats which are impermeable to petrol will absorb ethanol and water and eventually turn into "sinks".
A useful tip is to run the tank dry before laying up for winter and then putting 1/2 a gallon of alkylate pure petroleum (white gasoline) such as Aspen 4T into the tank and allow it to fill the float chamber. No ethanol, no water, first time start in the Spring.
I avoid supermarket petrol when I can and certainly at the end of the season use only the Super or Powerplus etc as these have little or no ethanol content.
Note the above post went in just before mine. It is far more eloquent than mine!
