E10 petrol – what is it and can I use it in my Toyota?

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.

  1. My Alphard ’53’ also runs on LPG with the JLM kit, it has the 2AZ-FXE engine which isn’t mentioned on any site, which fuel should I use? My LPG garage only sells E10

    1. Hi,

      We recommend continuing to use E5 fuel, which will remain available at most petrol stations (in normal fuel supply situations).

      Thanks

    1. Hi Lawrence,

      As detailed above, 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.

      Therefore your 2002 Yaris can use E10.

      Thanks

  2. Hi there, some advice please . . .

    We have a Celica built in 2003 and first registered in 2004 that was a Japanese import. It is a 1800cc, 3-door hatch back:

    Variant: ZZT230(L)
    Version: ZZT230R-BLFGHW(1E)
    Type Approved Number: E11*98/14*0122*04
    VIN/Chassis/Frame No.: JTDDR38T300159618
    Engin Number: IZZ-FE

    Can you let us know whether we should us E10 or not, please?

    Many thanks

    John

    1. Hi John,
      Thanks for your comment.
      Your Celica can use E10 petrol.
      Worth noting that it is not a Japanese Import though!
      Thanks.

  3. Hello, I have a AUTOMATIC Toyota aygo 2005,LC55 RZP.
    I have been using E10 for 3 weeks and have had issues with the petrol gauge. After driving 200 miles the petrol gauge only moved 1 block down (50-55miles worth) . Normally after 200 miles I would have a 3rd left of fuel in the tank. When I try filling up it would only let me fill up 15 litres worth which does not cover my weekly milage. Luckily I’ve been recording my milage so I know when to fill up.
    I wondered if E10 affects automatic cars? Am I the only one reporting this issue?

    1. Hi Mya,
      We would recommend taking your Aygo to your nearest Toyota Centre.
      They will be able to physically inspect your vehicle and provide any necessary repairs.
      Thanks.

  4. I’m buying a Japanese imported Toyota Alphard people carrier. It is a 56 plate and registered in January 07. It is currently being converted to a camper van. Can I use E10 petrol

  5. Hi
    Thanks for confirming I can use e10 in my Verso S. However I have been reading of many people using additives now – would you recommend this? If so, any advice as to which to choose?

    1. Hi there,
      We wouldn’t specifically recommend using fuel additives.
      However, if you were to use the correct volumes, we don’t think you’d experience any issues.
      Thanks.

  6. Hi, I have a 2006 Yaris FP56NTK
    Is this okay on E10?
    Also do you know if it is okay on E10 if in the long run there will be any effects to the rubber seals and such.
    Only this is a low miler I own and concerned about any immediate damage that might be caused by the new fuel.
    Thanks in advance

    Jason

    1. Hi Jason,
      Your Yaris can use E10.
      The higher blend of ethanol can cause corrosion of some rubbers and alloys used in the engine and fuel systems of some older vehicles, but not your Yaris.
      Thanks.
