ethanol absorbs water that's half the reason you don't want it
then with the weather events bringing heavy flood rain fall and supermarkets mostly built like most modern housing estates on flood plains the likely hood of water in petrol is exceptionally high
if you ONLY sell Petrol your reputation matters - if you make 99% of profit from running a supermarket they don't care if your car or bike runs well (and if you buy at a supermarket chain nor do you)
as shedamn says - but worth repeating - yes at refineries its all a std base blend BUT the additives used vary so Esso and Shell you get good stuff
If you live in the right places they don't even put ethanol in super unleaded at esso garages
