Ethanol has been present in petrol now at lower concentrations for 20 years or so and will already have left its mark on our engines. It is only the recent arrival of 10% ethanol which has brought the issue to the fore.

 

I hope you can find this brief description of the current scenario helpful.

ESSO have provided the following statement

​

What’s in our Synergy Supreme+ 99 premium petrol

​

Our ESSO Synergy Supreme+ 99 petrol has more cleaning power than our regular petrol – and includes molecules whose job it is to reduce the friction in your engine helping the moving parts work more efficiently.*

Although our pumps have E5 labels on them, our Synergy Supreme+ 99 is actually ethanol free (except, due to technical supply reasons, in Devon, Cornwall, North Wales, North England and Scotland). Legislation requires us to place these E5 labels on pumps that dispense unleaded petrol with ‘up to 5% ethanol’, including those that contain no ethanol, which is why we display them on our Synergy Supreme+ 99 pumps.

There’s currently no requirement for renewable fuel, like ethanol, to be present in super unleaded petrol although this could change in the future, in which case we would comply with any new legislation.
