Petrol in Diesel

0333 366 0103

Put Petrol in a Diesel Car in Aberkenfig?

If you have not fired up the engine as yet, don't. A drain and nothing else is almost always what a car needs while the petrol is still in your tank and the engine has not run, which is why it is the following few minutes that matter, not how much was put in. Petrol in Diesel comes to your car wherever it has ended up in Aberkenfig or the rest of Bridgend, on the forecourt, at the roadside or on a driveway, and drains and cleans it there. One ring to us will be enough: our technicians can explain what follows from here. Try it right away.

What to do next about petrol in a diesel

  • Feed a petrol motor diesel and it will generally not run at all, and so the driver stops there and so does the harm. Give a diesel petrol and the car starts, it ticks over, it drives off — all right for a few miles. Drivers have that backwards, which is the bit they get wrong about petrol in a diesel specifically. So never fire it up. And once started, never believe it: your fuel system is wearing as you drive.
  • Leave your ignition off also. Diesel performs two jobs: it burns, and before it combusts it greases that high-pressure pump and its injectors. Petrol manages the first but not the second. Flicking the ignition on is commonly all it takes to prime the system, which pulls the petrol out of the tank and into exactly those parts.
  • That guidance supposes a diesel fuel system copes with petrol by percentage. It will not. Pour diesel on top and nothing at all is cleared; what you get is a bigger tank of the same mix. And no, the grade makes no difference — super unleaded is simply petrol.
  • We would rather get to a difficult location than have it started — so if you reasonably can, sit tight. Nothing is easier to handle than a car that has never shifted. On the verge on Dunraven Street, that means hazards on and leave the car.
  • Our van arriving rather than circling turns on two things: a postcode starting CF32 9, and whatever is next to you with a sign on it. Get both prepared before you call.
  • Three answers decide the entire job: the stuff you poured in, the ballpark amount involved, plus if it has been running since. Our number is 0333 366 0103.

The journey back would roughly double it, for no reason at all. One commute has already sent a real amount of petrol-thinned diesel through the high-pressure fuel pump of that Volkswagen Passat. So leave the vehicle where it sits. Phone us from the platform if that is quicker — nobody needs you hovering over your car at Sarn while our engineers work, and tonight trumps finding out on Monday.

Each start primes your fuel system and sucks more of the mixture out of that tank and on to your pump — which is why a car moved twice into a roomier space has quietly become a bigger job than one left precisely where it stopped. So where our engineers cannot work next to the diesel Skoda Octavia, we shift the vehicle without running it. None of that is pedantry about a few seconds of running. Car parks like the one at Lidl our technicians attend all the time, and your fuel is rarely the awkward part: the bay is. Vehicles either side, a trolley shelter behind, at times a height barrier at the entrance deciding if our van can reach you at all. Tell us how hemmed in you are, and which way the vehicle points.

You will be told to shift it clear of the gateway and sort it out later. Do not. On the zig-zags outside the local primary school, a misfuelled Peugeot 308 running on diesel is in the way, and that's all it is. Start it three more times being polite and you have turned a tank into a fuel system: every start primes your lines, every prime draws more petrol past the filter toward the pump. Let them complain. Phone.

Ringing from near St John's Church? Three things help us. The filler — which side of the car it's on. Room for our van next to you, without the road being blocked. And whether anything has run since the fill-up. The spot itself scarcely matters: on-street is where our technicians work most, and we would far rather have a narrow bay than a car someone has driven somewhere easier. Then it's a drain for the Mercedes C-Class, a filter change where there is one worth changing, lines cleaned, clean fuel put round the entire system. By now the worst of that is in the fuel lines and not the tank.

Authorisation first, where there's a hire firm or a company behind the car — some agreements demand it, and settling that beforehand saves a great deal of time later. After that, phone us about the diesel Dacia Duster close to Aberkenfig Library. You'll not know how full that tank was. Scarcely anyone does, two days into a motor, and it gets worked out on the spot anyway. Our technicians ask because the harm petrol does in a diesel is proportional: a couple of litres in an almost empty tank make a much stronger mixture than the same few in a full one, and since petrol is designed to resist igniting under pressure, which is precisely what a diesel relies on, the stronger it gets the more the motor knocks and smokes and flattens off.

At the forecourt: removing petrol from your diesel

A good chunk of the work gets finished at the pump, as that is where it often kicks off. Still at Texaco? Then that is normally where it happens. Garage forecourts are everyday for us, with the permission of the owner.

A filling station is the single place the mistake can be stopped before the motor has run. Everywhere else — a car park, a driveway, a lay-by — the car was fired up and driven to get there, which means fuel was sucked from your tank, through your filter then into the high-pressure pump. That's not a calamity, and our engineers can still deal with it where it sits. It does mean your lines and the fuel filter need rinsing as well as the tank, and that is determined by the few seconds between seeing the till receipt and reaching for the key.

Move it out of the way if the attendants offer, and they usually will. The next customer gets by the pump, and that's worth doing. Cranking it to roll four car lengths is not.

Areas we cover around Aberkenfig

Tondu, Sarn, Tyn-y-garn, Fountain, Cymdda — all of them on our trips that bring us over to Aberkenfig itself, a village.

There are pages for the majority of locations around Bridgend, and the ones listed above are just the immediate neighbours — so yours being left off that list tells you nothing at all about if we come. Contact us to check rather than guessing — boundaries particularly, and wherever your phone may get wrong.

Look at this map for the area covered on this page. The lot is ground our engineers work: a kerbside, a forecourt, a drive, a car park. You don't bring the car anywhere.

Kerbside stops in Aberkenfig

Not everyone gets the chance to pull in anywhere safe. A normal call for us and not an unusual one: worked out after setting off, finished up along the verge beside Pandy Road or in a lay-by with your hazards flashing.

Fine right there? Stay with it. Not fine? Climb out and clear of it. It will often oblige. A diesel running on petrol limps along quite willingly, and that is the problem: start it up to reach somewhere better and that mixture goes further into the fuel system with every mile driven. Pressing on does the vehicle far more harm than a technician heading out to a difficult place, and that's no bother for us.

Run it already? Stop, and read this

Here is where the local M4 counts, under a mile out of Aberkenfig. A drop in power, an uneven idle, smoke: those are the symptoms when they appear, rather than a tidy stop — and a wrongly fuelled diesel will usually take you onto it and some distance along before anything feels wrong at all.

Come off at the next safe junction, switch off, and don't start the car to reposition. Suppose the worst of that on a long drive. Anything close to the under 25 miles to the closest city, and the contamination has been through the fuel filter, through the pump, through the fuel injectors. Say so when you call. What we bring differs.

All about Aberkenfig

Aberkenfig is a village situated on the riverside in Bridgend, Wales, with a mix of terraced housing and other residential properties. Aberkenfig lies at an elevation of 40 metres, close to the nearby villages of Tondu, Sarn, and Tyn-y-garn. Aberkenfig is located near the city of Swansea, which is approximately 15.8 miles away. Aberkenfig has a population of around 1911 people, making it a small but distinct community in the area.

When we reach you in Aberkenfig: what follows

  • Three things get established before any price — the fuel that got in, the quantity, and if anything has been run since. Each answer shapes the work.
  • Your tank gets cleared completely.
  • What is left in your system shouldn't be what created the problem, so the lines get flushed and your filter cleaned.
  • Your system gets primed, on clean diesel.
  • We turn it on and check it runs correctly on fresh diesel.

From that point, you're ready to set off. We do all of it wherever the car has come to a stop, which means it never has to be taken to a workshop, and if it has been spotted early, it's very uncommon for there to be lasting damage.

AdBlue in a diesel tank in Aberkenfig is a different job

AdBlue rather than petrol? Then the first step is unchanged — your engine remains off — while the fault underneath it is a different one altogether. Petrol thins your diesel and takes away the protection your fuel system relies on. Urea in water, AdBlue, and in a diesel tank that brings rust and residue.

Usually the more significant of the two, AdBlue — and the details sits on its own Aberkenfig page. Both are ours to handle.

Paying for a petrol-in-diesel drain in Aberkenfig

What shifts the price is listed below, since this job isn't one job and our technicians cannot truthfully put a single price on this page.

  • This is the big one: whether your engine has been run, or driven.
  • How much of the wrong fuel got in, compared with how much the tank holds.
  • The type of fluid in the tank, petrol or AdBlue.
  • Whether our van can sensibly get to the vehicle and work on it, which hinges on where the vehicle is.

The vehicle, the amount, whether it has run — give us those and the answer comes back straight rather than as a range. Vehicle at home, going nowhere, nothing time-critical about it — is ideal for that.

Petrol in diesel queries from Aberkenfig drivers

I'm on a forecourt around Aberkenfig. Can you drain the vehicle here?

Yes — forecourts are where a big portion of this takes place. We work at Welcome Break and the other forecourts around town routinely, with the site's consent — tell us which one you're at when you call and we will tell you if we can work there.

How much petrol is too much for a diesel?

Ratio settles it instead of litres — and more than either, whether your engine has run. Five litres in a nearly empty tank is a separate situation from five in a full one — but either way, the thing that determines how much work is required is if that mixture has been pulled through your fuel system.

I drove the vehicle after putting petrol in my diesel. Now what?

Switch off somewhere sensible, then keep it that way after you stop. Driving is what takes the trouble from the tank into the pump and injectors — but it is salvageable much more often than motorists assume, and the single most helpful thing you can do now isn't restart it.

Fuel drains and manufacturer warranties

A manufacturer's warranty survives a drain then flush done to a proper standard, which is no alteration at all. Another good reason to leave it turned off: running a diesel on petrol is the thing likelier to cause an argument with one.

Could I put some two-stroke in and just drive?

Two-stroke oil solves a separate fault, and an old one at that. Nothing it does puts back what petrol weakened. No. Petrol remains in that tank afterwards, whatever else goes in, and your pump gets no break from it.

Main dealers and petrol in a diesel

Wherever the car is, our technicians drain and clean it there, so a visit to the main dealer does not come into it.

Is your vehicle still with you?

The engine stays off.

If you have already driven the car, pull in somewhere sensible, turn it off and leave it off. Cold, stationary, going nowhere: that's the best place to be in. Drivers fear this far more than they need to.
