I have a someone coming to clean out the tank https://www.wrongfuelsos.co.uk/wrong-fuel-petrol-in-diesel-from-120-00-chewton-keynsham-somerset/

Then do I just fill with petrol and hope for the best?

Once the tank is empty and filled with petrol again it should be fine. Might be a bit smokey if the car has been run after filling. The people coming to empty tank will keep you right. My old mum did similar but put petrol in her diesel. Got it emptied and refilled with diesel and no probs. I always thought that diesel nozzles wouldnt fit in a petrol? Fill the tank to the top so any diesel left will be very diluted.

The people who're going to drain the tank should advise you more comprehensively, but brim it with petrol, and top up with 2 or 3 gallons until you've effectively filled the tank from empty once, then run it to the reserve and refill.

Expect some relatively smoky starts until this is complete.

How did you manage this? I thought diesel pump nozzles were bigger diameter and don't fit?

Was wondering the same?

Just for info, if you have AA cover they have the proper vans to take the fuel out of the tank away.

Here's some advice from an AA rival for balance. - https://www.rac.co.uk/drive/advice/know-how/wrong-fuel-recovery/

Must admit I was wondering but the diesel may not have ben dispensed by a fuel station fuel pump and if it's done it's done.

Super service, drained the tank flushed. put in a couple of gallons checked the fuel line which was good and clean.

I refilled the tank with petrol and drove home he followed me until I turned off. A load off my mind.

If I had, had trouble I would have been alerted! but it just went in as normal.

Perhaps Skoda opted for a universal fuel tank neck??

The Garage is an ESSO station, the Diesel came from a Supreme pump.

Yeah, they do fit at some filling stations. I dodged a bullet the other week nearly doing the same thing at a Shell garage.

Personally, I'd keep the tank filled above half for as many miles as possible, so it keeps any contamination as diluted as possible, but that's really splitting hairs, and not one to worry about either way.

In the UK the nozzle of a filling-station's diesel pump nozzle has (or should have!) a larger diameter than that of a petrol pump nozzle and, consequently, it should not be practicable to insert a diesel pump nozzle FULLY into the fuel-filler of a petrol fuelled car

The difference in nozzle-diameter will be visibly apparent in this YouTube video.

'Misfueling' is much more common the other way round - petrol in diesel-fuelled car - as the narrower-diameter petrol nozzle can be fully inserted in the diesel-car's fuel-filler.

Although the video claims that it is 'impossible' to insert a diesel pump's nozzle fully into a petrol-fuelled car's fuel-filler that's not always the case (as StevesTruck has advised).

(I know that the nozzle of my local Morrisons filling-station's diesel pump won't go into my wife's petrol-fuelled 2009 Skoda Roomster's fuel-filler. Having become habituated to years of ownership of diesel-fuelled vehicles, I unthinkingly attempted to refuel her Roomster from the Morrison's diesel pump. "That's ****** odd", I thought, when the pump's nozzle refused to go fully into the Roomster's fuel-filler and then I noticed that I was using the wrong pump. Since then I've been VERY careful to double-check that the pump I'm using matches the vehicle's fuel type.)

You can accidentally when not thinking (and bursting for a pee to find the petrol station/shop hasn't a toilet) put diesel in an old petrol car, guess how I know.

Out of interest I compared the fuel-fillers of my 2009 Skoda Roomster and 2024 Skoda Fabia SE L (both petrol engined).

Not far down the Roomster's filler pipe is a sturdy plastic 'constrictor' with a circular hole in it. This hole has a narrow diameter and only a narrow diameter petrol-pump nozzle would pass through it. As it would be impossible to push a diesel-pump's larger-diameter nozzle through the constrictor, the chances of anyone (be they ever so mentally challenged or stressed!) accidentally putting diesel into my Roomster's fuel tank are minimal.

HOWEVER, although not far down my Fabia SE L's filler pipe there is also a plastic 'constrictor' with a hole in it, that hole is SIGNIFICANTLY LARGER than the Roomster's and it wouldn't surprise me in the least (and as gumdrop found to his cost) that a diesel-pump's nozzle could be pushed through the Fabia's constrictor.

So "Cave Fabiam cum reficies" as my Latin schoolmaster would not have said.

I am not in the habit of forcing mechanical bits, in fact with apprentices it was one of those things along with safety

that I uttered until they understood, Don't Force Things if you have to there is probably something wrong.

Probably filler neck and openings can have a wide variations and still be within 21st-century German engineering tolerances. 😉

It's was done and it was sorted, another life lesson and experience, probably be remembered more than many more important ones.

At least it was better quality diesel. 😄

This 2014 BRISKODA thread mentioned accidentally putting diesel into a 2007 petrol-fuelled Octavia.

but online comments indicate that this type of misfuelling is definitely not limited to Volkswagen Group vehicles.

related to a Nissan "Note" and - as I said above - it would not be practicable to insert a diesel-pump nozzle through the 'restrictor' in my 2009 Skoda Roomster's fuel-filler.

I've taken another look at the fuel-fillers of my 2009 Roomster and 2024 Fabia.

In the UK the 'spout' of a standard petrol-pump's nozzle has a diameter of 22mm, whereas the spout of a (non-truck) diesel-pump's nozzle is said to have a diameter of 24mm or 25mm.

The 'restrictor' in my Roomster's fuel-filler pipe is shaped like an inverted cone and made of smooth hard plastic with inclined sides designed to lead the pump-nozzle steeply downwards towards the hole in the restrictor's centre.

I found a length of hard plastic tube that happened to have an outside diameter of 22mm and inserted this into the Roomster's fuel-filler pipe. When the plastic tube was about 80mm into the pipe, it reached the hole in the restrictor and slid through the hole easily with no effort on my part. There was a tiny 'air gap' between the inside of the hole and the outside of my 22mm-diameter plastic tube, so it might be possible to push a 22.5mm-diameter pump nozzle through the Roomster's fuel-filler's restrictor, but impossible to push through a nozzle with a diameter larger than that. I could insert a nozzle with (say) a diameter of 24mm into the Roomster's fuel-filler pipe, but it would only go in about 80mm and then be stopped by the restrictor. So I COULD put diesel into the Roomster, but to do this would mean that most of the diesel-pump's nozzle would be outside the fuel-filler pipe and this should definitely alert a person refilling the car and guard against accidental misfuelling.

I repeated the exercise with my Fabia. The 22mm-diameter plastic tube went into the (much less downwards angled) fuel-filler pipe about 80mm and then met resistance. I pushed the tube a little more firmly and it continued to go in, but, unlike the Roomster, there seemed to be no 'air gap' between the 'restrictor' and the tube, with the tube being gripped by the restrictor. I gained the impression that the Fabia has a sort of 'soft' restrictor (possibly to prevent fuel fumes being released to the outside air) and, consequently, it MIGHT be possible to push a good bit larger-diameter nozzle through it. If that's the case, as there was a need to actually push the 22mm-diameter plastic pipe through the restrictor, the chances of misfuelling my Fabia with diesel are higher than for my Roomster.
