A new and more eco-friendly fuel has been rolled out across Britain’s petrol stations – but many people still don’t know how it will impact their motor.

E10 petrol, which is made with up to 10% bioethanol – a type of renewable fuel – will be the standard offering at forecourts as part of Government plans to cut carbon emissions.

It is replacing E5 petrol, blended with up to 5% bioethanol. 

The motoring experts at LeaseCar.uk  have simplified what this change means for motorists and the environment along with what car owners can do if their car isn’t compatible with the new petrol grade standard.

A spokesperson from LeaseCar.uk said: “Drivers should be aware of this change and what it means, but sometimes we get given so much information that it actually confuses us further. That's why we wanted to break down in the simplest of terms what this change to E10 petrol actually means.

“It’s important to get one thing clear, if you own a diesel vehicle you won’t have to worry about this. E5 and E10 are types of petrol so this won’t affect your car.

“In the long run it is much better for our environment and a lot of countries have already made that switch like Germany and France.”

Here are the most asked question about E10 petrol – and some expert answers to them:

1. What is the difference between E5 and E10 petrol?

The current petrol grade is E5 which is made up of 95% regular unleaded petrol and 5% renewable ethanol (hence the name).

Tim Alcock from LeaseCar.uk says “E10 will be much more beneficial to the environment as it will contain 10% ethanol and 90% of regular unleaded petrol. Essentially this will cut down the CO2 transmissions from our vehicles.”


2. What do you do if your car is too old?

Cars which are manufactured from 2011 onwards will be able to take the new E10 petrol grade.

“If you’re unsure whether or not your car is compatible, the government has created a section on their website where you can check if E10 is suitable for your car,” says Tim.

Cars manufactured will be able to use E5 petrol at most petrol stations by purchasing the ‘super’ grade petrol which will be more expensive.

Tim says: “If your car is not compatible, there will still be E5 petrol available to use, it will just be more expensive.”

3. What happens if you fill your car with the wrong kind of petrol?

Tim said: “Drivers should also take care when filling up their cars to avoid putting in the wrong petrol. If you do accidentally put E10 in your car which is only compatible with E5, don’t worry too much.

“Just wait until there is room to add more petrol in and fill it with the correct one.

“This isn’t as bad as filling a petrol car with diesel, you won't have to get the car drained out but you should still take care and pay attention to what you are filling your car up with because it can cause long term damage.”
