Are You Ready for E10?
E10 fuel is a blend of 90% gasoline and 10% ethanol, and it is becoming the new standard for gasoline in many countries. As the adoption of E10 fuel expands, it is important to understand if your car is compatible with this new fuel type. This article will explore which cars are compatible with E10 fuel and provide insight into the benefits and potential drawbacks of using this fuel blend. We will also discuss any necessary adjustments that car owners may need to make to ensure their vehicles run smoothly on E10 gasoline.

What You'll Learn

Vehicle compatibility checker
Introduced in September 2021, E10 fuel is now available at all UK petrol stations and will eventually replace E5 fuel as the standard grade across Britain. E10 fuel is a greener option, with an estimated reduction of 750,000 tonnes of carbon dioxide emissions per year.
Most petrol vehicles manufactured after 2010 are compatible with E10 fuel. However, there are exceptions, including certain models from major brands like Ford, Toyota, Volkswagen, Audi, and Mercedes. If your vehicle was manufactured between 2000 and 2010, it will likely be able to run on E10 fuel, but it's always good to check.
To check if your vehicle is compatible with E10 fuel, 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). The government's online checker is also available in Welsh (Cymraeg). Alternatively, you can contact the manufacturer directly to confirm your vehicle's compatibility.
It is important to note that diesel and electric vehicles cannot use E10 petrol. If you own a classic car or a vehicle with a specific engine type, you should be cautious as some older models may not be compatible with E10 fuel. For example, some V6-powered Lexus models made before 2007, certain Volkswagen and Audi models produced before 2005, and Renaults with 2.0-litre engines built before 2003 are not compatible with E10 fuel.

Cars manufactured after 2010/2011
If your car was manufactured after 2010 or 2011, it is likely compatible with E10 fuel. In general, cars produced after 2011 are pre-approved to use E10 petrol fuel. This is because the European Union Fuel Quality Directive introduced a new market petrol specification from 1 January 2011, allowing for petrol to contain up to 10% ethanol by volume, commonly known as 'E10'.
While most modern cars are compatible with E10 fuel, there are some exceptions. It is recommended that you check your vehicle's compatibility before using E10 fuel. You can do this by referring to the minimum octane rating inside your vehicle's fuel cap or in the owner's manual. Additionally, you can check online using your vehicle's manufacturer, model, engine size, and year of manufacture.
It is important to note that E10 fuel is not suitable for all types of vehicles. Diesel and electric vehicles, for example, cannot use E10 petrol. If you own a diesel car, you can continue to use B5 or B7 fuel as usual. Furthermore, some cars that are compatible with 5% ethanol may not be compatible with E10, so it is important to exercise caution when referring to your car's fuel requirements.
If you unintentionally fill your car with E10 fuel when it is not approved for your vehicle, it is recommended to fill it up with E5 fuel afterward. If you fill the tank completely with E10, it will need to be emptied, and it is not advised to drive the car.

Exceptions: Ford, Toyota, Volkswagen
Most petrol vehicles are compatible with E10 fuel. However, diesel and electric vehicles cannot use E10 petrol.
Ford
While I could not find specific information on Ford cars, you can check if your car can run on E10 petrol by checking online. You will need to know the vehicle manufacturer, model, engine size, and manufacturing year. You can also check the log book (V5C) for your vehicle.
Toyota
If your Toyota has a petrol engine or hybrid powertrain and was officially produced for European markets since January 1998, it will be compatible with E10 petrol. The only exceptions to this rule are some Avensis models. You can also refer to your owner's manual to confirm.
Volkswagen
I could not find specific information on Volkswagen cars. However, as mentioned earlier, you can check if your car can run on E10 petrol by checking online or referring to the log book (V5C) for your vehicle.

Diesel and electric vehicles
E10 fuel was introduced to all UK petrol stations in September 2021. It is a greener type of petrol that contains 90% traditional petrol and 10% ethanol, which is derived from the fermentation of plants and their by-products. This new fuel has replaced the previous E5 as the standard 95 RON unleaded at forecourts across the UK as part of efforts to cut the country's CO2 emissions.
However, not all cars are compatible with E10 fuel, and some older models, especially those manufactured before 2002, won't be able to run on this type of fuel and could suffer damage if filled with it regularly. Diesel and electric vehicles, in particular, cannot use E10 petrol. This includes hybrid vehicles that are powered by both electricity and diesel.
If you own a diesel or electric vehicle, you should not use E10 fuel. Filling up with a single tank of E10 petrol into a vehicle that isn't compatible will unlikely cause major problems or engine damage, but you should avoid doing so in the future. Prolonged use of the incorrect fuel may cause harm.
To check if your vehicle is compatible with E10, you can use the government's online checker tool. 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).

E5 fuel as an alternative
E10 fuel is now the standard grade at UK fuel stations, and most modern vehicles are compatible with it. However, E5 fuel is still offered as a 'protection-grade' fuel for older vehicles that cannot use E10. E5 is typically marketed as "high-octane" or performance fuel and will be labelled as such.
E5 fuel contains 95% unleaded petrol and 5% ethanol, while E10 contains 90% unleaded petrol and 10% ethanol. Ethanol is derived from the fermentation of plants and their by-products and is more environmentally friendly. The higher ethanol content in E10 means it is considered less stable than E5 and could cause corrosion in older engines.
E5 is usually super unleaded, which has a higher octane rating than regular E10 unleaded. This only makes a difference to your engine if your ECU can make use of the higher octane rating. E5 fuel can also improve fuel economy, as it is more energy-dense than E10, although the difference is small.
If your vehicle is compatible with E10, it is safe to mix the two grades of petrol. However, if you are repeatedly filling your vehicle with the incorrect fuel, it could cause long-term damage.
