Thank you for contacting Esso Customer Care.
The majority of unleaded 95 Octane petrol sold in the UK contains 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 grade petrol).
Esso super unleaded petrol (Synergy Supreme+ Unleaded 97) is ethanol free (except in Devon, Cornwall, the Teesside area and Scotland) and we have no current intention to add ethanol to Synergy Supreme+ in other areas of the UK.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 or Cornwall, the Teesside area or Scotland.
Yours sincerely,
Daniel Jankovits
