I have for the last few months been using ESSO 97 (no ethanol) instead V-Power (5% ethanol) with no issues.
I went to refill the tank yesterday at my usual garage and it appears that Esso have upgraded their fuel from 97 to 99. (Synergy 99)
It still contains NO Ethanol!
(note that it still says E5 on the pump, but ESSO themselves say it contains no ethanol unless in Devon or Cornwall.....see website below
Surely this is what we have all been waiting for?
