There is an ethanol free option available
From Esso,
What is the ethanol content of your fuels?
The majority of unleaded 95 Octane petrol sold in the UK contains up to 5% ethanol as required under the Government’s Renewable Transport Fuels Obligation (RTFO).
There is currently no requirement for renewable fuel (such as ethanol) to be present in super unleaded (97 and 99 grade petrol).
Esso super unleaded petrol (Synergy Supreme+ Unleaded 97 and Synergy Supreme+ 99 ) is ethanol free (Except in Devon, Cornwall, North Wales, North England and Scotland). We would therefore advise anyone who has concerns about the presence of ethanol in petrol to use Synergy Supreme+ – providing they do not fill up in Devon, Cornwall, North Wales, North England and Scotland. The European standard BS EN228 covers the requirements for 0-5% ethanol unleaded petrol, the labelling requirement for zero % ethanol is E5 (as is up to 5%), a E0 label doesn’t exist.
