What You'll Learn
Cars built after 2010 are compatible with E10 fuel
E10 fuel was introduced to all UK petrol stations in September 2021 to help reduce carbon emissions. It contains 10% ethanol, which is a 5% increase compared to E5 fuel. This makes it a much greener option, estimated to potentially reduce carbon dioxide emissions by 750,000 tonnes per year.
While most modern cars can run on E10 without any issues, not all cars are compatible with this type of petrol. Classic car insurance brand Hagerty has warned that E10 fuel could cause significant damage to the fuel system and engine of older cars. The RAC has advised against using E10 fuel in any car built before 2002.
However, if your car was built after 2010, it will be compatible with E10 fuel. Most cars built between 2000 and 2010 are also compatible, but there are some exceptions, including models from major brands such as Audi, Ford, Mercedes, Toyota, and Volkswagen. If you own a car from one of these manufacturers and are unsure about its compatibility with E10 fuel, you can contact the manufacturer or use the government's online E10 checker.
It is important to note that diesel and electric vehicles cannot use E10 petrol.

Compatibility with older car models
E10 fuel, a new type of unleaded petrol, was introduced to all UK petrol stations in September 2021. It contains 10% ethanol, which helps to reduce carbon emissions produced by an engine. While most petrol vehicles will be able to use E10, some older models are not compatible with this type of petrol.
If your car was built after 2010, it will be compatible with E10 fuel. If it was built between 2000 and 2010, it will likely run on E10 fuel. Nearly all Fords dating back to 1992 can run on E10, as can Nissans, Peugeots and MINIs built after 2000. However, there are some exceptions, including models from major brands like Ford, Toyota, Volkswagen, Audi, and Mercedes. For example, E10 petrol is not cleared for use in the following vehicles:
- Audi A4 Saloon petrol engine models with OEM parking heater, of model years 2001-2008
- Audi A4 Avant petrol engine models with OEM parking heater of model years 2002-2008
- Bora - 1.6 litre (81kW) FSI Saloon and Estate made from October 2001 to September 2005
- Golf mark 4 - 1.6 litre (81kW) FSI made from November 2001 to May 2004
If you are unsure about whether your car is compatible with E10 petrol, you can check online or contact the manufacturer. You will need to know the vehicle manufacturer, model, engine size, and year it was manufactured. This information can be found in your vehicle's log book (V5C).

E10 fuel's impact on fuel economy
E10 fuel, a blend of unleaded petrol and bioethanol, was introduced to UK petrol stations in September 2021. It contains twice as much bioethanol as the previously standard E5 fuel, with 10% ethanol and 90% unleaded petrol. This blend has been available in other European countries since as early as 2009 and is now the standard 95 octane petrol grade in England, Scotland, and Wales.
E10 fuel has a negative impact on fuel economy, with drivers experiencing fewer miles per gallon due to the lower energy density of ethanol. The US Energy Information Administration (EIA) estimates that vehicle fuel economy may decrease by about 3% when using E10 fuel. Some sources state that the reduction in miles per gallon could be as high as 4%. The impact of E10 fuel on fuel economy varies depending on the vehicle, driving conditions, engine type, fuel system design, and driving habits.
The introduction of E10 fuel as the standard grade at petrol stations has also resulted in increased fuel costs for some drivers, as E5 fuel is now a premium option. While E10 fuel is not more expensive than E5, the reduced fuel economy means that drivers may end up paying more overall for fuel. This is particularly true for drivers of older, incompatible cars, who have no choice but to use the more expensive E5 fuel.
It's important to note that not all cars are compatible with E10 fuel, and using it in an incompatible car can cause long-term damage. Owners of classic cars and older models may encounter issues when using E10 fuel. However, most cars built after 2010 are compatible with E10, and some cars built between 2000 and 2010 may also be compatible.

E10 fuel's impact on the environment
E10 fuel, a blend of 90% gasoline and 10% ethanol, is considered a more environmentally friendly fuel option compared to traditional petrol. It has the potential to significantly reduce carbon dioxide (CO2) emissions from vehicles, contributing to a greener and more sustainable transportation sector.
The introduction of E10 fuel at petrol stations is a step towards reducing greenhouse gas emissions and combating climate change. The ethanol component in E10 fuel is derived from renewable sources, such as sugar cane, grains, corn, beets, and other energy-rich plants. This bioethanol reduces the amount of carbon emissions produced by an engine, making it a lower-emission alternative to conventional unleaded fuel. It is estimated that E10 fuel could reduce CO2 emissions by 750,000 tonnes per year in the UK, which is equivalent to taking up to 350,000 cars off the roads.
However, it is important to note that E10 fuel is not without its drawbacks. Firstly, not all vehicles are compatible with E10 fuel. Older car models, classic cars, and even some newer vehicles from major brands like Mazda, Rover, Nissan Micra, Ford, Toyota, Volkswagen, Audi, and Mercedes may not be able to run on E10 fuel. This incompatibility could lead to issues such as pre-detonation, rough running, and poor cold starting. Secondly, due to the lower energy content of ethanol compared to gasoline, E10 fuel results in decreased fuel economy, leading to slightly higher fuel costs for drivers.
Despite these challenges, the adoption of E10 fuel is a step in the right direction for the environment. While it may not be suitable for all vehicles, it offers a greener option for those who can use it. As countries work towards meeting their emissions targets, the increased use of E10 fuel, combined with other measures, can contribute to a more sustainable and environmentally friendly future.

How to check if your car is compatible with E10 fuel
If you want to check if your car is compatible with E10 fuel, there are a few steps you can take. Firstly, you should know that most modern cars built after 2010 are compatible with E10 fuel. If your car was manufactured between 2000 and 2010, it will likely be able to run on E10 fuel, but there may be some exceptions. Older cars, especially those built before 2002, are more vulnerable to damage from E10 fuel.
To check your car's compatibility, you can use the government's online checker. You will need to know the vehicle manufacturer, model, engine size, and year of manufacture. This information can be found in your vehicle's log book (V5C). Once you have this information, you can input it into the online checker to see if your car is compatible with E10 fuel.
Additionally, you can contact the vehicle manufacturer directly to inquire about your car's compatibility with E10 fuel. They will be able to provide specific information about your car model and year of manufacture.
It's important to note that diesel and electric vehicles cannot use E10 petrol. If your car is incompatible with E10 fuel, you can still access E5 unleaded at some filling stations, although it may be sold as premium or super unleaded.
By taking these steps, you can ensure that you are using the correct type of fuel for your car and avoid any potential damage that may be caused by using incompatible fuel.
