It’s estimated that more than 27% of UK motorists are yet to check whether their car is compatible with the new E10 petrol, with some entirely unaware that the new fuel has been introduced to replace E5 as the standard grade of unleaded petrol.

Segensworth Automobiles are encouraging drivers to check their vehicle’s compatibility with E10 petrol as soon as possible via the free official online checker.

Those with incompatible vehicles, which are estimated to total around 600,000, will have to seek out and pay for more expensive, E5 super unleaded if they wish to keep them running. For those drivers who know their main car is not compatible with the new E10 fuel, the impact of the cost of having to fill up with super unleaded instead, which can cost around 12p more per litre than standard unleaded, is the single biggest concern. Some are concerned about finding forecourts that sell E5 super unleaded in the first place or fear mistakenly filling up with E10, something that may cause expensive damage to non-compliant 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. However, those who fill a non-compatible 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. All vehicles sold in the UK from 2011 are required to be E10 compatible.

The Government says that all cars built since 2011 can use E10 petrol. The fuel arrived across forecourts in Great Britain earlier this year.
