The fuel in petrol pumps is set to change this year and most petrol cars will be able to use it.

E10 petrol – a mixture of petrol and 10% renewable ethanol – will replace the existing E5 petrol, which contains less ethanol, in September 2021. The switch could cut CO2 emissions by 750,000 tonnes a year, or 350,000 fewer cars on the road.

Will it work in my car?

Renewable fuels have been mixed with UK supplies for over a decade and E10 fuel will still be safe to use for most petrol cars.

A small number of older vehicles, such as classic cars and some from the early 2000s, won’t be able to use the new fuel. They’ll need to continue using E5 petrol, which will still be available at the pumps but under the premium ‘Super’ option.

Rising fuel costs

Introducing E10 will increase fuel costs for petrol users. Although it’s estimated that E10 will cost 0.2p less per litre than E5, the new petrol has a lower energy content, so you’ll need to stop at the pumps more regularly.

The Government estimates that fuel costs for cars using E10 petrol will increase by around 1.6%. That goes up to around 8% if your car isn’t compatible with E10 and you need to use the more expensive E5 ‘Super’ grade.

Fuel prices have already been steadily increasing in recent months and, by the end of February 2021, prices were the highest they have been since the UK’s first lockdown in March 2020.
