Changes to UK Petrol Summer 2021
Motorists across the country will start to see the standard (95 octane, often branded as unleaded) petrol grade in the UK become E10.
E10 petrol contains up to 10% ethanol, current petrol contains up to 5% ethanol (referred to as E5). E5 will continue to be available in some forecourts in super grade (97+ octane).
A small number of vehicles (around 5%) will not be able to use the E10 fuel. Petrol vehicles not compatible with E10 will need to keep using E5 petrol, which will remain available in the ‘super’ grade of petrol (97+ octane).
The Department for Transport has introduced an online GOV.UK E10 vehicle compatibility checker which motorists can use to find out if their car, motorcycle or moped can use E10 fuel.
Incorrectly fuelling a vehicle with E10 petrol will not cause immediate harm, but if it is used regularly it could damage engine parts.
E10 is one simple step to help motorists reduce the environmental impact of every journey they take, through reducing carbon emissions.
