Get ready for E10 fuel

From 1st September 2021, the standard (95 octane) petrol grade in Great Britain will become E10. This will be introduced from early 2022 in Northern Ireland.

The change in fuel applies to petrol only. Diesel fuel will not be changing.

Almost all (95%) petrol-powered vehicles on the road today can use E10 petrol and all cars built since 2011. If your petrol vehicle or equipment is not compatible with E10 fuel, you will still be able to use E5 by purchasing the ‘super’ grade (97+ octane) petrol.

You can use the UK Govt’s vehicle compatibility checker to see if your vehicle can use new E10 fuel here

01 What is changing and when?

From the start of September 2021, the standard petrol grade in the UK will become E10. Welcome Break will be moving from E5 to E10 petrol in line with Government guidelines, whilst E5 will still be available at selected Welcome Break filling stations.

02 What is Ethanol?

Ethanol is an alcohol-based fuel produced from plants including sugarcane and grains.

03 What is E10 petrol?

Previous E5 petrol contained up to 5% renewable ethanol. E10 petrol contains up to 10% renewable ethanol, hence “E10.”

04 Are all vehicles compatible?

About 95% of all petrol vehicles are able to use E10. You can check your vehicle on the Government E10 compatibility checker:

05 Are classic cars compatible?

Some classic cars and motorbikes may not be compatible with E10 fuel. Again, you can use the Government E10 compatibility checker. If your vehicle is not listed, you are advised to contact the vehicle’s manufacturer or consult a mechanic. In the meantime, you are advised to continue using E5 unleaded fuel.

06 What to do if a vehicle is not compatible?

You can continue to use E5 unleaded fuel, which will still be available at selected forecourts.

07 Will E10 fuel cost more?

At present, it’s not clear how the increase in Ethanol will impact prices going forward.

08 What happens if E10 is used on an incompatible car?

Accidentally using E10 fuel in an incompatible car will not cause an immediate problem. However, you are advised to ensure you use E5 petrol on your next filling.
