The new E10 petrol grade is being introduced across the United Kingdom from September 2021. The move is part of the government’s strategy to reduce harmful emissions from transport
Although the new E10 petrol retains the same 95-octane rating as existing unleaded petrol, it contains a much higher proportion of ethanol. Currently, all petrol supplied at filling stations contains a five per cent mix of ethanol, which is why it is known as E5. However, from September 2021, that proportion will be doubled in standard grade petrol. The fuel will be 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 is the ethanol content being 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.
Is 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.

Hi there, I have a Toyota Yaris Verso 2001 1.3 Auto will I be able to use E10 not sure if this model was made in Europe or Japan
Hi Andrew,
Please provide the reg.
Thanks
I have a Japanese import Toyota Alphard 2.4 petrol GX03GNY.
Can the vehicle use the new E10 petrol?
Thankyou.
Hi Andrew,
Sorry we can’t advise on imported vehicles so we can only recommend that you continue to use E5 fuel.
Thanks
What will happen if I use e10 in my 1az fse powered Avensis? Will damage occur because it is direct injection?
I have been hearing european drivers state that their 1az fse runs fine on e10, but this is obviously contradictory to your advice.
My car REG is HD02KKP
Hi Phil,
Thanks for your comment.
Your vehicle is not approved for E10 fuel. The higher amount of ethanol can damage the rubber pipes and seals in the fuel system, and degradation may start to occur to the fuel system.
E5 fuel will continue to be available in super unleaded form, and this can be used in your Avensis without any damage occurring. Please continue to use E5 petrol.
Thanks.
Thank you for this advice!
Is it plausible to upgrade the affected components in the car?
I have heard that the aluminium parts within the high pressure fuel pump would also degrade even if I were to upgrade hoses etc.
Many thanks
Hi Phil,
As the work needed would be classed as a modification away from manufacturer’s specification, this is not something we can assist further with. Sorry for that.
The only advice that we can give is that you continue to use E5 fuel.
Thanks
Hi I have a 1987 toyota mk1b mr2 can this use e10 and if not do toyota have a fix or modification
Thanks
Hi Niall,
Thanks for getting in touch.
If your vehicle was produced before January 1998, it cannot use E10 fuel. Therefore, a 1987 MR2 cannot use E10 fuel.
There is no modification available. Please continue to use E5 petrol.
Thanks.

I have a Toyota Yaris versco 1992 can I use E10
My Yaris is diesel
Would this be suitable
Hi Joanne,
E10 is petrol. As your Yaris is a diesel, please do not use E10 petrol, or petrol of any kind.
Thanks.
Hi,
Could you please advise me if my Toyota Avensis Reg GK54YBB is fitted with the dreaded 1AZ-FSE engine, as the manual shows two engines were installed 1AZ-FSE and 1AZ-FE?
Kind Regards,
Michael.
Hi Michael,
Thanks for your comment.
The engine suffix for your vehicle is FSE.
Unfortunately, this means you cannot use E10 petrol.
Thanks.

thanks
David Overland
Hi David,
Thanks for your comment.
Toyota Avensis with 2.0-litre 1AZ-FSE engine made between July 2000 and October 2008 are unable to use E10 petrol.
As your vehicle was produced in September 2006, it cannot use E10 petrol. Please continue to use E5 petrol.
Thanks.
