More than a quarter of UK motorists haven’t checked to see whether their car is compatible with the new E10 petrol arriving later this month. A further 24% of motorists are unaware that the new fuel is being introduced to replace E5 as the new standard grade of unleaded petrol.

Segensworth Automobiles are encouraging our customers to check their vehicle’s compatibility with the new blend of petrol as soon as possible via the official Government online checker.

With more than 600,000 incompatible vehicles on the road, some motorists will have to seek out, (and pay more for), E5 super unleaded.

Motorists, whose main car is not compatible with the new E10 fuel, will be most impacted by the cost of having to fill up with super unleaded instead; which can cost around 12p more per litre than standard unleaded.

More than 50% of motorists are worried about finding forecourts that sell E5 super unleaded in the first place, while a fifth (20%) fear mistakenly filling up with E10; something that may cause extensive damage to older vehicles. 

The new E10 petrol contains up to 10% bioethanol, replacing E5 which has up to 5% and is being introduced to cut carbon dioxide emissions.

It has been estimated that the switch to E10 will cut CO2 emissions by 750,000 tonnes a year, or the equivalent of taking 350,000 vehicles off the road and is part of the Government’s 2050 net-zero carbon target.

Motorists who fill an older vehicle with E10 petrol could find that it may cause damage to seals, plastics and metals over longer periods as a result of bioethanol’s corrosive properties. 

The Government says that all cars built since 2011 can use E10 petrol. The fuel is arriving across forecourts in Great Britain now and is due to arrive in Northern Ireland in early 2022.

The shift to E10 from E5 should not result in higher petrol prices in the future, as the higher cost of bioethanol has already been included in the wholesale price of the fuel for some time. Having said this, motorist’s with older and therefore incompatible vehicles will find themselves out-of-pocket having to continue to use the more premium E5.
