Changing from E5 next month.  Not likely to affect many, but may be worth checking here.

    I didn't realise this though it is unlikely to be a problem for most..

    You can use this link to check if your car is compatible https://www.gov.uk/check-vehicle-e10-petrol

    Only 95 Ron petrol has it though, the 97 Octane stuff uses E5. I’ve replaced all the flexible fuel hoses on my classic and am using an additive to help combat the effects.

    Why on earth is this information not highlighted at the petrol pumps?

    Is that right? 5 percent of pre 2011 cars can't take it whereas they can take 95? That should be clearly marked.

    That is a good point.

    Yes should definitely be marked up. All I noticed was E10 advertised at the pump

    I don't know about the UK but here in France the pumps are marked 95 / E10 so I've just assumed it's the EU changing the name of it

    That sounds like it’s pot luck when you turn up at a pump as to whether you get the 5% or the 10% put in your tank.

    Most cars will be okay. But I have heard it destroys lawn mower engines.

    Edited to add an explanation - it's winter storage issues mainly it seems: https://www.burkesbackyard.com.au/blogs/don-burkes-blog/petrol-warning/

    It not not only destroys old rubber parts but attacks ali. I bought some petrol taps from the USA, they have had E10 for many years and on inspection the taps were eaten away and had to be junked.

    I won't be using E10 in any of my motorbikes as they date from 1952, I won't even risk it in my 2018 bike.

    Luckily the van and car are diesel.

    Thanks for that. Maybe this explains why my lawnmower now requires 2L of petrol rather than the 1.5L that was previously sufficient. I'd assumed that the lawnmower was just aging.

    So hang on, in the UK there are now 3 unleaded options: SP95, 98  & E10? Is that right?

    Saw at the petrol pump yesterday that this has already changed. Didn't even know about it till i saw the E10 on the pump handle.
    Seems that most cars are ok. I have a Ford fiesta and my parents Renault Megane but both look like they can handle it. The government should of at least sent a leaflet to everyone as you might not know about the change. I certainly didn't.

    Not quite. All of the old 95 Octane which was E5 (that is had 5% ethanol in it) is being replaced with E10 (that is 10% ethanol) which is still 95 Octane.
    Then Super Unleaded is either 97 or 98 Octane which will stay as E5.
    There are also some premium fuels like Shell V-Power and Tesco Momentum which are 99 octane which will also stay as E5.

    Some cars used to specify that 98 Octane fuel was a minimum. (My old Audi RS4 did; TVRs are another). We were advised by a BMW dealer to fill 1 in 4 times with 98 Octane for Mrs cafcfan's car. It seems there are better additives/lubricants in the higher grade fuel. 

    My dealer says I can use either but lose about 10% horse power on the lower grade. My own back of an envelope calculations seem to suggest that I get marginally more mpg on Tesco 99 Octane than their regular stuff which pretty much cancels out the extra cost. But that might not be the same for all vehicles, (my car is weird and also uses 10W-60 oil because of the very high pressures involved. Same stuff as used in motorsport I believe).

    With lower grades one buys, Smoke gets in your eyes.

    Problem is the ethanol added to the petrol, E5 has 5% and E10 has twice as much ethanol at 10%.  Esso Synergy Supreme unleaded is ethanol free but only 91 octane level but I use it for all my garden machinery.

    Interesting @cafcfan. If my car mirrors my lawnmower then it's certainly worth paying more for 98. My lawnmower has made a 33 per cent increase in fuel consumption!
    @Dippenhall maybe has shown me the way to go for the latter.

    According to the Esso web site, https://www.esso.co.uk/en-gb/fuels/petrol Synergy Supreme is 99 Octane and is E5.

    My lawnmower works on black coffee and some of the wife's homemade chocolate cake. Never had issues with fuel consumption.

    My bad I got 91 octane from the Canadian site.

    As I read the Esso UK site it says the new law applies to "Regular" fuel but not "Super unleaded".

    Unless the wording needs to be updated, it currently says:

    Although our pumps have E5 labels on them, our Synergy Supreme+ 99 is actually ethanol free (except, due to technical supply reasons, in Devon, Cornwall, North Wales, North England and Scotland). Legislation requires us to place these E5 labels on pumps that dispense unleaded petrol with ‘up to 5% ethanol’, including those that contain no ethanol, which is why we display them on our Synergy Supreme+ 99 pumps.There’s currently no requirement for renewable fuel, like ethanol, to be present in super unleaded petrol although this could change in the future, in which case we would comply with any new legislation.

    That's good to know thanks.

    The government should definitely have publicised this more, as having not read this thread I filled my car up with E10 today, without checking that it's ok - my car is elderly, rather than a classic. 

    Having gone to the link it's fine, but I'd rather have checked first!

    Filled up with E10 for the first time today.
    Car broke down within a few minutes and garage say its beyond economic repair. Not happy. 

    Granted it's a Merc diesel but even so...
