thank you for clearing that up.
The main point of the message is unchanged. Increasing levels of ethanol in petrol will cause more problems with older vehicles especially if they are not used regularly.
It seems to me that we chase one problem only to introduce another. After being encouraged to buy diesels to reduce CO2, we get more NOx. Switching back to petrol and adding ethanol we introduce more ground level ozone.
