Posted 12th Sep 2021
My car is a 2014 golf and is apparently compatible with the e10 fuel but since using it my car has started idling rough and not as smooth as before. Could easily be something else and I’ve booked the car in for tomorrow but just wondering if any one else has had problems.

    Maybe save yourself some money, cancel your booking with your garage for tomorrow and continue driving your car and fill up in future with super unleaded, which is still E5, and see if the problem with rough running goes away.
    If it doesn't, you'll know there really is a problem with your car that is unrelated to the fuel, and you can re-book it with your garage so they can investigate.

    Hopefully you're not taking it to Kwik Fit?

    Not noticed any issues with my 2019 Fabia. Super Unleaded is still E5, albeit a bit more expensive, if the issue still continues.

    That defies science! There is less energy contained in ethanol than petrol hence you're more likely to see a reduction.

    Yea that’s an option as garages always find something wrong with my car……

    There are no problems with E10, except on much older cars (20 year old+) with internals prone to corrosion. You'll also need to get hold of a fuel additive when storing the car for long periods, as the higher concentration of ethanol means more water absorbtion from the air.

    The only other downside is a slight reduction in fuel efficiency, supposedly around 3%. Very much doubt the 5% saving in petrol will be passed on to us at the pumps, of course...

    So no, it has nothing to do with E10.
    Rough idling is typically a sign of constriction, either in air intake (get a look at the filter) or the fuel injectors (the carlube/Redex stuff won't do jack).

    No took it in today as no garages open. They didn’t have the guy in who looks at things like this but one of the workers said they’d had similar problems linked with fuel. Will take it to my local garage as could be anything just odd it’s started since I’ve started on the e10

    My Kuga has the same Engine, I've also had it remapped. it'd be nice if my MPG improved 34.4mpg although that's mainly town driving.

    Simple timeline.
    Industry made aware of change plans.
    Industry plans all new builds, refurbs then whats left in the estates to make the change.
    Consumer Education starts
    Media produces shock stories/headlines
    Deadline of compliance passes
    Consumers start complaining.

    I always use the same petrol station since its been built. Since you changed to E10 I have been having issues.
    Oh, ok, btw, you have been using E10 for the past 8 months the store was opened.

    The changes did not happen magically overnight in the entire country, but yet the complaints mostly did. (edited)

    That would be cool if you did, I just wish I could explain because like you said I should see a reduction I will keep an eye on it and see if anything changes I just wondered if the remap had anything to do with it as I’m not very technically minded and thought it was strange and to be honest I didn’t t even realise I filled up with E10 the first time, so I just put the increase in mileage to that but who knows

    I think it’s down to the eco boost technology and the 42 litre tank but the remap did help me get a slightly better fuel economy, I drive reasonably fast and do really give it some from time to time. Yeah I was tempted to, mine cost me just over 16k in 2016 new (was a really good deal) but paying 20k plus for a fiesta is insane but the orange is amazing plus I prefer my shape to the new one. I don’t think there is a better car pound to power then the fiesta st 2013 - 2017 (edited)

    Ha ha so true. I noticed the tesco fuel I was using was E10 months ago when they first announced the changes (had never checked before). Luckily it works fine in my 20 year old car.

I'd recommend changing your engine oil more frequently as it can dilute it and make it more acidic thus being more corrosive and offer less lubrication etc


    Thanks mate will definitely keep an eye on it.

    In Brazil ethanol blends e27 gasoline.
    Not heard of any trouble from the people I know.

    Diesel is 7% ethanol. Seems not to be a problem so far but time will tell I guess. I'm not worried as cheap stuff will be going in (edited)

    Took the car into the garage and they found nothing with the diagnostics check. As soon as I told him I’d used the e10 he told me that is the problem and he’d been inundated with people phoning about their cars misfiring and idling rough.

    Ford tend to have relatively large fuel tanks
  29. Willy_Wonka's avatar
    Now, I may be stupid, haha, but I would have thought if you have rubbish in the fuel filter building up from the previous fuel type then this build up would have some sort of interaction with a new fuel blend, which might dislodge some of the unwanted grim. So maybe changing the fuel filter would be advisable.

    Makes sense to me.

    Lovely car, though I'm sure you didn't choose it for the mpg figures! Remember seeing one of the special editions of it in the showroom beside a pair of the 595's (mad price). Nearly made me think twice about the Giulietta Cloverleaf I was ordering at the time, except I needed a 5 door amd slighter bigger. (edited)

    Well I guess the remap may help in some way, They've been using E10 in Europe for a long time etc.. I used some E10 in mine and it felt sluggish, so last time I filled up I used super unleaded and it seems forever since I last filled up but I think it's most definitely just a placebo. I think I'll alternate between super and E10 and compare the difference. Super unleaded is very rarely worth it but if my car performs better with it then I'll use that instead. I don't do that many miles so not too bothered about MPG.

    My son has a 2007 Fiesta which is apparently compatible however after a couple of tanks full of E10 it illuminated the dreaded P0171 engine code. Just changed to super unleaded and so far so good.
  34. joyf4536's avatar
    We have three vehicles. One runs of autogas so doesn't count. One higher performance and runs fine on E10 although we don't use it all the time in this one, and one runabout, been using E10 for a couple of years (not in UK) with no issues. Simply don't notice the difference. (edited)
  35. speedfire66's avatar
    Is it true that E10 breaks down gaskets, plastics and damages internals over time due to the raised ethanol content? I run 97-99 mostly in my car (F56 S) and I’ve put E10 in once and it felt really bad so never put that in again lol
