In the astra manual that I have, recommended is usage of 95 (e5 if I understand correctly) but also tolerable 91 (e10 if I understand correctly). However, this is for EU and UK. I think on auto by auto basis we can find the info in manuals.

However, the cheaper option has higher petrol usage so partially offsets the saving.

AFAIK the E10 will still be 95 RON.

There are some dodgy methods to remove the ethanol from fuel,apparently some classic car and light aircraft owners are already doing it,

Ethanol has a naturally high octane rating (approx 110), so removing it from the fuel may not leave you with the octane rating of fuel you think you bought. In yet another 'win' for the fuel companies, I expect this means they can reduce the percentage of octane improvers and higher octane petrol in E10 compared to E5.
