Can my Toyota use E10 petrol? Compatibility guide and FAQs

Can I use E10 petrol in my Toyota?

Most Toyota petrol and hybrid vehicles produced for Europe since January 1998 can use E10 petrol safely. Exceptions include certain Toyota Avensis models with 1AZ-FSE and 2AZ-FSE engines produced between 2000 and 2008. The advice in this article is relevant to the UK market.

Key takeaways

• E10 petrol contains up to 10% renewable ethanol.
• Most Toyota petrol and hybrid vehicles built since 1998 are compatible.
• Some early Avensis models are exceptions.
• Imported vehicles may require E5 fuel.
• E10 helps reduce transport-related CO₂ emissions.

The new E10 petrol grade was introduced across the United Kingdom from September 2021. The move is part of the government’s strategy to reduce harmful emissions from transport.

Although E10 petrol retains the same 95-octane rating as existing unleaded petrol, it contains a much higher proportion of ethanol. Prior to the introduction of E10, all petrol supplied at filling stations contained a five per cent mix of ethanol, which is why it is known as E5. However, from September 2021, that proportion doubled in standard-grade petrol. The fuel is identified by the code E10.

This change will not affect Toyota owners with a diesel-powered vehicle.

Which Toyota models can use E10 petrol?

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 the following vehicles:

• Toyota Avensis with 2.0-litre 1AZ-FSE engine made between July 2000 and October 2008.

• Toyota Avensis with 2.4-litre 2AZ-FSE engine made between June 2003 and October 2008.

If your vehicle was produced before January 1998, it cannot use E10 fuel.

Can you use E10 petrol in imported cars?

If your car is an imported model that was not officially sold in European markets, we recommend staying on E5 by using super unleaded, which has a higher octane rating. Having received queries from owners regarding specific imported models, we are investigating this further.

How can I check if my Toyota can use E10 petrol?

This can be confirmed by checking the owner’s manual or looking at the information printed on the inside of the fuel filler flap. If you are still unsure, use E5 petrol, which will continue to be dispensed from the super unleaded pump at many filling stations.

Why was the ethanol content increased?

Ethanol is a renewable, non-fossil biofuel produced from sustainable sources. It is made using by-products from the farming industry, such as those from wheat, corn and sugar crops.

By increasing the proportion of biofuel in petrol, the content of fossil fuel and therefore our reliance on it decreases. This will reduce the overall levels of CO2 (carbon dioxide) emissions from vehicles and help the government achieve its climate change targets. It has been calculated that this change from E5 to E10 petrol will cut harmful transport emissions by 750,000 tonnes a year. That’s the equivalent of taking 350,000 cars off the road.

Why isn’t the ethanol content much higher?

The composition of ethanol is different to that of a crude oil based fossil fuel such as petrol. Higher blends of ethanol can cause corrosion of some rubbers and alloys used in the engine and fuel systems of some older vehicles.

A small number of these vehicles will need to continue using E5 petrol, and this will remain widely available at filling stations in super unleaded grade.

Did this change to E10 petrol only happening in the UK?

No. In fact, E10 petrol is already common throughout the world. It has also been the reference fuel used for all new car emissions and performance testing since 2016.

Frequently Asked Questions About E10 Petrol

Can I use E10 petrol in my Toyota?

Most Toyota petrol and hybrid vehicles produced for the European market since January 1998 are compatible with E10 petrol. The main exceptions are certain Toyota Avensis models fitted with 1AZ-FSE and 2AZ-FSE engines built between 2000 and 2008.

Can Toyota hybrid cars use E10 petrol?

Yes. Most Toyota hybrid vehicles manufactured for European markets since January 1998 can safely use E10 petrol, provided they are not one of the specific exceptions identified by Toyota.

How can I check if my Toyota is compatible with E10 petrol?

You can check your vehicle’s owner’s manual or look for fuel compatibility information on the inside of the fuel filler flap. If you are unsure, Toyota recommends using E5 petrol.

What is E10 petrol?

E10 petrol is a standard unleaded petrol that contains up to 10% ethanol, a renewable biofuel made from sustainable sources such as wheat, corn and sugar crops. This is an increase from E5 petrol, which contains up to 5% ethanol.

Does E10 petrol affect vehicle performance?

For most drivers, there will be little noticeable difference in everyday driving. E10 petrol retains the same 95-octane rating as the E5 unleaded petrol it replaces.

Can I still buy E5 petrol?

Yes. E5 petrol typically remains available as super unleaded fuel at many filling stations, providing an option for vehicles that are not compatible with E10.

Can imported Toyota models use E10 petrol?

If your Toyota was imported and was not officially sold in European markets, Toyota recommends using E5 petrol via the super unleaded pump unless compatibility has been confirmed for your specific model.

Why was E10 petrol introduced?

E10 petrol was introduced to help reduce transport-related carbon emissions by increasing the proportion of renewable biofuel in petrol and reducing reliance on fossil fuels.

What happens if I accidentally fill my car with E10 petrol?

If your vehicle is approved for E10 fuel, there should be no issue. If you believe your vehicle may not be compatible, refer to the owner’s manual or seek advice from a Toyota Centre before continuing to use E10. This article advises owners to confirm compatibility before using E10 fuel.

Is E10 petrol suitable for older vehicles?

Toyota states that vehicles produced before January 1998 are not compatible with E10 petrol. Owners of older vehicles should continue using an appropriate alternative fuel.
