  Warranty 4 Apr 2013 (Ask HJ)
  When I bought the Evoque the salesman made much of a failsafe device in the fuel filler neck which would prevent misfuelling. Filled diesel car with petrol...

  Confusion transfusion 31 Oct 2009 (Ask HJ)

• Honest John’s Motoring Agony Column 24-06-2017 Part 2 26 Jun 2017 (Forum)
  I'm intrigued how the Mitsubishi PHEV owner managed to misfuel with diesel into his petrol tank. Tens of thousands of people a year misfuel petrol into diesel, but only about 4 people a year manage to get diesel into a petrol car, because the diesel fuelling nozzle won't fit (you have to be REALLY determined and dribble the fuel in).

  Just had a call from a hysterical SWMBO who has just put 6 litres of Unleaded in the Scenic. Thankfully she realised and stopped at 6 litres, and of course...

  Do the car manufacturer's have their misfuelling prevention devices backwards? 15 Dec 2012 (Ask HJ)
  I think the motor industry has got it the wrong way round in its effort to prevent misfuelling. It is impossible to put diesel into a petrol tank but this...

• C`Rail misfueling Engineers solutions? 18 Jan 2007 (Forum)
  Question, What is a global solution to common rail diesels being misfueled? (With emphasis to elegant mechanical/electrical engineering rather than ( for example) a triangular *cat flap* on the filler neck and matching pump, oh, and with just a nod to occam`s razor :) Some suggested parameters It needs to work anywhere, not just a UK solution, so its ok at that rural garage in France and over the EU borders.
• Topics - above, in bold type 17 Oct 2017 (Forum)
     Please also take the trouble to reply and update the thread as to the eventual outcome  (and possibly proffer thanks if the advice has been helpful)'       This post is prompted by curiosity as to outcomes,and by a recent post from a motorist asking for advice re misfuelling  - but eventually checked that she hadn't actually misfuelled!

  My car judders when accelerating - could this be down to previous misfuelling? 19 Jan 2018 (Ask HJ)
  On odd occasions my 2013 BMW X1 suffers the judders as I accelerate through the gears. As if it doesn't know whether to go on - but you can easily just...

  How can I add fuel additive to my Ford Focus when it has a misfuelling prevention device fitted? 6 Apr 2013 (Ask HJ)

• Which device to prevent misfuelling? 13 Jan 2017 (Forum)
  At £40 it's rather expensive for a small piece of moulded plastic, but since the cost of a misfuelling is so high it seems worth it even at that price. I'm sure that with a bit of competition and increased production volumes, the cost of this sort of gadget will come down in price a lot, but I want one now.
• Citroen C Crosser 4x4 2,2 Diesel - Car Hesitating on reapplication of throttle 8 Apr 2013 (Forum)
  My car has been hesitating badly since I misfuelled with unleaded. I only drove 200m before parking up to go shopping - afterwhich the car would not restart. Called out the Fuel Doctor who completely drained down the tank and got the car started on diesel again.
• Hyundai Bayon - New car misfuel advice 16 Mar 2024 (Forum)
  Drove home 110 miles, left it a few days before travelling on holiday did another 150 miles, with no performance issues and very good mpg numbers... when the engine failed, got towed back to my local dealer, and they have diagnosed a misfuel (diesel in petrol tank). I have a receipt to say I filled up with petrol, dealer is saying they did not put any fuel in and suggest i contact Hyundai UK. The fuel sample has not yet been sent off for analysis but currently the fuel system has been flushed, cleaned and I needed a new fuel injector on cylinder 2.
• Land Rover Discovery 4 - Restricted performance 25 Sep 2015 (Forum)
  This time the dealership have replaced the "fuel rail pressure", but it has happened again. One question the LR garage keep asking is has the car ever been misfuelled? - Not in our ownership of the last 9 months or so and hitherto we have had 5,000 miles or so of completely untroubled motoring - never misfired our even the suggestion of such. The six month RAC warranty we had when we acquired it has expired, but that aside we find it baffling that the LR garage keep suggesting it has been misfuelled given its performance over the last 9 months.
