 E5 & E10 petrol again. A government update. - henry k
From a motoring club.

After an extensive consultation process, the Department for Transport has announced that they will legislate to introduce E10 petrol as the standard 95-octane petrol grade by 1 September 2021. They will also require the higher-octane 97+ ‘Super’ grades to remain E5 to provide protection for owners of older vehicles. This product will be designated as the ‘Protection’ grade.

The introduction of the 95-octane E10 grade and the maintenance of the Super E5 protection grade will be reviewed by the Government after 5 years to ensure they remain appropriate to the needs of the market. In relation to the E5 protection grade, such a review will examine market developments over the period. HM Government have sought to reassure members that, without a suitable alternative becoming available, it is highly likely the Super E5 protection grade would continue to be available.

Filling stations that stock 2 grades of petrol and supply at least one million litres of fuel in total each year, will need to ensure one product is the Super E5 protection grade. While not all filling stations meet these criteria, almost all towns across the UK will have a filling station that supplies the ‘Super’ grade and currently one major retailer, a national supermarket group, has committed to offer the product. The main exception to this is in certain parts of the Highlands, north and west coast of Scotland, which will be covered by an exemption process and allowed to continue to market the 95-octane E5 grade.

The Federation therefore recommends that all vehicles produced before 2000 and some vehicles from the early 2000s that are considered non-compatible with E10 - should use the Super E5 Protection grade where the Ethanol content is limited to a maximum of 5%. If classic owners are interested in checking compatibility of vehicles produced since 2000, then we recommend using the new online E10 compatibility checker:

It should be noted that some Super E5 Protection grade products do not contain Ethanol as the E5 designation is for fuels containing up to 5% Ethanol. Product availability varies by manufacturer and geographical location and enthusiasts should check the situation in their location.

The reasons given for considering the introduction of a standard of fuel containing up to 10 per cent bioethanol, centre around attempts to make significant savings on carbon emissions as the government makes attempts to meet its climate change targets.

Typically, fuel companies currently blend petrol with up to 5% bioethanol and diesel with 7% biodiesel. The government have a target to ensure that 9.75% of all transport fuels must come from renewable sources by the end of this year under their “Renewable Transport Fuel Obligation”. The government believe that a move to standardising E10 fuel will be equivalent to taking 350,000 cars off the road each year. The Department of Transport estimates that this may cut CO2 emissions for transport by 750,000 tonnes per year.

E10 is of concern to historic vehicle owners because it may cause some flexible fuel hoses, seals, gaskets, plastics and certain metals critical to the fuel system to corrode or degrade. This may cause damage to fuel pumps, carburettors, seals on injectors, pressure regulators and fuel tanks that are not resistant to ethanol. The bioethanol may also dislodge particles on older fuel systems causing blockages.
