E10 fuel is a blend of petrol and ethanol, containing up to 10% renewable ethanol. It is considered more environmentally friendly than the previous standard, E5, which contained up to 5% ethanol. While E10 is compatible with most petrol vehicles manufactured since the 1990s, it is estimated that around 600,000 vehicles on UK roads are not compatible with the fuel. This includes some older vehicles and classic cars, as well as diesel and electric vehicles. Using E10 in an incompatible car can cause long-term damage, particularly to seals, plastics, and metals, due to ethanol's corrosive properties. To determine whether your car is compatible with E10 fuel, you can use the government's online checker or consult your vehicle's user manual.

E10 fuel is a biofuel made up of 90% regular unleaded and 10% ethanol
E10 fuel is said to be partially carbon-neutral because the plants that will become biofuel absorb carbon dioxide from the atmosphere. This offsets the carbon dioxide released into the atmosphere when ethanol is used as fuel. It is estimated that the use of E10 fuel could reduce CO2 emissions by 750,000 tonnes per year, which is the equivalent of taking up to 350,000 cars off the road.
E10 fuel is compatible with most petrol-powered cars on the road today. However, it is estimated that around 3% of vehicles, or about 600,000 cars, on the road in the UK are not compatible with E10 fuel. Drivers of cars registered prior to 2002 are advised not to use E10 in their vehicles, as problems have been reported. These cars can instead fill up with high-octane super unleaded, which is still E5. As of 2011, all new cars sold in the UK must be E10 compatible.
If you put E10 fuel in an incompatible car, the car will still run, but it may cause long-term damage. The ethanol in E10 has corrosive properties that can damage seals, plastics, and metals in older cars. E10 fuel is also hygroscopic, meaning it absorbs water from the atmosphere, leading to condensation in fuel tanks if the car remains unused for long periods.

It is compatible with most cars manufactured since the 1990s
E10 fuel is compatible with most cars manufactured since the 1990s. In fact, since 2011, all new cars sold in the UK must be E10 compatible. This means that if you own a car that was manufactured after 2011, your car is likely compatible with E10 fuel.
E10 fuel is a biofuel made up of 90% regular unleaded and 10% ethanol. It is considered more environmentally friendly than the previous standard, E5, which contained up to 5% bioethanol. The UK government estimates that the introduction of E10 fuel could reduce CO2 emissions by 750,000 tonnes per year, which is the equivalent of taking up to 350,000 cars off the road.
While E10 is compatible with most newer cars, it is estimated that around 3% of vehicles on UK roads (approximately 600,000) are not compatible with the fuel. If you use E10 fuel in an incompatible car, it will still run, but it may cause long-term damage to seals, plastics, and metals due to bioethanol's corrosive properties. Therefore, it is important to check if your car is compatible with E10 fuel before using it. You can do this by using an online checker or by consulting your vehicle's user manual or manufacturer.
If you own a classic car or an older vehicle, it is recommended to use super unleaded E5 fuel instead of E10. E5 fuel is still available at most filling stations, although it may be more expensive and harder to find than E10.

It is estimated that 3% of vehicles on UK roads are not compatible with E10 fuel
E10 fuel, which has been available across the UK since September 1, 2021, is a biofuel made up of 90% regular unleaded and 10% ethanol. While it is considered more environmentally friendly than the previous standard, E5, which contained up to 5% bioethanol, it is estimated that around 3% of vehicles on UK roads, or about 600,000 cars, are not compatible with E10 fuel.
Vehicles manufactured before 2011, particularly those registered before 2002, are less likely to be compatible with E10 fuel. Owners of classic cars are advised to be careful not to fill up with E10, as this could lead to damaged seals, plastics, and metals due to bioethanol's corrosive properties. If E10 fuel is put in an incompatible car, the car will still run, but damage may occur over longer periods.
To check if your car is compatible with E10 fuel, you can use the government's E10 online checker. You will need to know the vehicle manufacturer, model, engine size, and year of manufacture. Most petrol vehicles will be able to use E10 fuel. Diesel and electric vehicles cannot use E10 petrol.
If your car is incompatible with E10 fuel, you can use Super Unleaded or Premium petrol, which have 97 and 99 octane, respectively. These fuels will be more expensive, but they will also provide better performance. Alternatively, you may consider upgrading your car to be E10 compatible by replacing parts that are at risk of damage due to ethanol contamination, such as the fuel lines.

E10 fuel is considered more environmentally friendly than E5 fuel
The UK government estimates that the switch to E10 could cut CO2 emissions by 750,000 tonnes annually, equivalent to removing 350,000 cars from the road. This greener fuel aligns with the UK's commitment to reducing greenhouse gas emissions and increasing the use of renewable energy in transport.
However, it is important to note that E10 fuel is not compatible with all vehicles. It is estimated that about 600,000 to 700,000 older vehicles, particularly those registered before 2002, are not compatible with E10. Incompatible vehicles may experience issues such as damaged seals, plastics, and metals due to ethanol's corrosive qualities, as well as condensation in the fuel tank due to its hygroscopic properties.
While E10 fuel offers environmental benefits, it also has slightly reduced fuel efficiency compared to E5. E10 fuel contains more ethanol, which has a lower energy content than gasoline, resulting in a decrease in fuel economy. Drivers of E10-compatible cars may find they get fewer miles per gallon when using E10 fuel.

E10 fuel is less efficient than E5 fuel
E10 fuel is a blend of 90% gasoline and 10% ethanol, a biofuel made from feedstocks like wheat and sugar beet. This is unlike E5, which contains 5% ethanol and 95% unleaded fuel. The higher percentage of ethanol in E10 fuel makes it less efficient than E5 fuel.
Ethanol has a lower energy content than gasoline, resulting in decreased fuel economy. The US Energy Information Administration (EIA) states that the energy content of ethanol is about 33% less than pure unleaded. As a result, vehicle fuel economy may decrease by about 3% when using E10. This means that drivers will have to fill up their tanks more often, which can be inconvenient and costly.
The incompatibility of E10 with older car models is another issue. While most newer cars can use E10 without any problems, it is recommended that cars registered before 2002 use E5 fuel instead. Using E10 in an incompatible car can cause long-term damage to seals, plastics, and metals due to ethanol's corrosive properties. This is because ethanol is hygroscopic, meaning it absorbs water from the atmosphere, leading to condensation in fuel tanks if the car is unused for long periods.
Despite these drawbacks, E10 fuel is considered more environmentally friendly than E5. The UK government estimates that E10 fuel could reduce CO2 emissions by 750,000 tonnes per year, which is equivalent to taking up to 350,000 cars off the road.

Frequently asked questions
E10 fuel is compatible with most petrol vehicles manufactured since the late 1990s or early 2000s. All vehicles built since 2011 are compatible. You can check if your vehicle is compatible using the government's online E10 vehicle checker.
If your car is incompatible with E10 fuel, you can still use E5 fuel, which is available in the more expensive, higher-octane super-unleaded form.
E10 fuel is considered more environmentally friendly than E5 fuel. It contains 10% ethanol, which is produced from plants, and is said to be partially carbon-neutral. The UK government estimates that E10 could reduce CO2 emissions by 750,000 tonnes per year, or the equivalent of taking 350,000 cars off the road.
E10 fuel is less efficient than E5 fuel, so you will get fewer miles to the gallon. It is also more expensive. Additionally, if E10 fuel is used in an incompatible car, it may cause long-term damage to seals, plastics, and metals due to ethanol's corrosive properties.
