Petrol in Diesel

0333 366 0103

Put Petrol in a Diesel Car in Somersham?

If you have not turned on your engine as yet, do not. A drain and nothing else is almost always what a motor needs while the petrol is still in your tank and the engine has not yet been started, which is why it is the following few minutes that matter, not how much got in. Petrol in Diesel travels to your car wherever it has stopped in Somersham or the rest of Suffolk, on the forecourt, by the roadside or on a driveway, and drains and flushes it there. Our technicians can explain what your next stage will be. Contact us — this comes ahead of anything else.

Now what? Petrol in a diesel, step by step

  • Don't fire it up — and never trust it if it starts. Here is the part drivers have wrong about petrol in a diesel especially. A petrol engine fed diesel normally just will not run, so the motorist stops and the harm ends with them. A diesel fed petrol generally starts, idles and drives away just fine for a couple of miles. It isn't all right. It's wearing out that fuel system whenever you drive.
  • Two tasks, diesel: it combusts, and on the way through it keeps the injection pump and injectors oiled. Petrol only handles the one. Which is why the ignition stays off too — flick it on and you usually prime your system, and that is petrol leaving the tank for precisely those components.
  • Topping up clears nothing. It gives you a bigger tank of the same mix, since a diesel fuel system won't cope with petrol by percentage the way that guidance implies — so never tip diesel on top to dilute it. Type is immaterial too: super unleaded is petrol.
  • Stay where you are if you reasonably can. A motor that has never shifted is the quickest one to sort out, and we would much rather travel to a tricky location than have it started. If you're pulled up on the verge on Mill Lane, put those hazards on then leave it there.
  • Know where you are before phoning. A postcode beginning IP8 4, and the name of whatever is nearest to you. Otherwise our van circles rather than turning up.
  • Call 0333 366 0103. Prepare for three things — what went in, roughly how many litres, plus if your car has been started. Those replies decide all that happens next.

Phone before you move it. Petrol into a diesel Renault Megane this morning, and it at Needham Market ever since? Then the day has taken nothing from you: fuel sitting in a tank is idle, and any damage was done on the journey in, when your pump was pulling diesel that petrol had weakened.

Car parks like the one at Co-op Food are a spot our engineers visit all the time, and the fuel is rarely the complicated part. The bay is: vehicles either side, a trolley shelter behind, at times a height limit on the way in that determines if a van can access you at all. So tell us how penned in you are when you call, and which way the vehicle is facing. If we can't work next to the diesel Volkswagen Tiguan we will roll the vehicle without running it — and that is not fussiness about a couple of seconds of running. Every start primes your fuel system and pulls more of the blend out of the tank and towards your pump, so a car moved twice into a better space has silently turned into a bigger job than one left just where it stopped.

Twenty to nine. By Somersham Primary School. Late already, and the till receipt in your hand says unleaded. Turn the hazard lights on, leave your motor alone, and phone. You may think three miles is nothing, in your Skoda Octavia or anything else — except that fuel is supplied to demand, and a drive taken in a hurry demands a great deal of that.

The components that should be getting lubricated are grinding instead, and the motor gives no sign of that: a diesel on a diluted tank starts and drives off quite happily. Risk the trip home from The Duke of Marlborough? No. Call us and leave the Peugeot 308 where it stands.

Clattering, a lumpy idle, white smoke, a throttle gone dead. That is a misfilled diesel Mercedes C-Class telling you what's wrong. Turn off where you have stopped, close to Somersham Baptist Church or anywhere else, and never start it to find a better location.

Mobile fuel drain van at a diesel car in Somersham

Can petrol be drained from your diesel on the forecourt?

Pumps are where the work usually begins, and where a good part of it closes. The drain usually gets done on the spot. Still on the forecourt at Asda? Given the station's permission, that is somewhere we work, and often.

Before your engine has fired — a forecourt is the only place the mistake gets spotted. Everywhere else — a car park, a driveway, a lay-by — the car was switched on and moved to get there, which means fuel was drawn from your tank, through the fuel filter then into the high-pressure fuel pump. That is not a catastrophe, and we can still deal with it where it sits. It does mean the lines and your filter need cleaning as well as that tank, and that's settled by the few seconds between seeing the receipt and reaching for your key.

Attendants will normally help out pushing it out from the petrol pump, which lets the next customer get by. Welcome the offer. Four vehicle lengths isn't worth the risk.

Coverage in Somersham

Being a village, Somersham sees a routine visit, and the villages nearby come along on the same journey: Nettlestead and Offton, Flowton and Little Blakenham, Baylham Stone.

There are separate pages for nearly all locations around Suffolk, and the ones mentioned above are merely the nearest neighbours — so yours being absent from this list means nothing at all about whether our technicians come. Presuming is the thing to skip, particularly on a boundary or somewhere your satnav struggles. Contact us and check.

That map shows the patch the page spans. Kerbside, forecourt, drive, car park: every bit of it is ground our technicians work on, and none of that needs the vehicle to travel to us.

Kerbside call-outs around Somersham

The opportunity to pull in anywhere suitable does not come to everyone. A common call for us rather than an unusual one: realised after setting off, landed on the verge of Stocks Hill or at a lay-by with the hazard lights flashing.

Okay where you are? Stay by it. Not okay? Get out and clear of it. Every mile a diesel obliges you for on petrol pulls the mix further into the fuel system — and oblige it often will, which is why your motor does not get restarted to limp somewhere safer. We will take the van to an awkward location without any fuss, and for your car that is a lot better than driving on.

Petrol in a diesel, and the motor has moved

Your M11 is the one which matters now, and runs under 50 miles from Somersham. It will frequently get you onto it, and some way along, before you notice a thing. Then it is some smoke, a lumpy idle and power draining away — not a clean stop. Wrongly fuelled diesels rarely give you one of those.

The first sensible exit is the one to take. Turn off there, then leave the restarting alone. It affects what we bring, so say so when you ring: on a longer trip — anything close to the under 25 miles to the closest city — assume the petrol has been through the fuel filter, the pump and the injectors.

Where is Somersham?

Somersham is a small village in Suffolk, situated on the riverside at an elevation of 23 metres, with semi-detached housing being the predominant type. Somersham lies near the villages of Nettlestead, Offton, and Flowton, and is approximately 15.6 miles from Colchester. Somersham is also within commuting distance of London, being around 64.5 miles away. Somersham has a population of around 704 residents.

What we do when our engineers arrive with you around Somersham

  • The replies change the work, which is why our engineers ask before giving a price: what went in, how much of that, and whether your motor has run.
  • Your tank gets cleared of everything.
  • Fuel lines are flushed through and the fuel filter cleaned, leaving nothing in the fuel system that started any of this.
  • Our engineers put new diesel in and prime your system.
  • The motor is fired up and tested to be sure it runs correctly on fresh diesel.

Then it's ready to set off. Lasting damage is very uncommon when it has been caught quickly, and since everything is done where the car is, it never needs to go to a garage.

Somersham AdBlue removal is a different problem

Don't fire it up: that first rule holds whether what was put in was AdBlue or petrol. What differs is this issue itself. Thinned diesel, and no protection left for the fuel system that depends on it. That is petrol. Corrosion and build-up are what a diesel tank gets instead, as AdBlue is urea in water.

Both are ours. There's a separate Somersham page for AdBlue removal, with the detail on it — including the reasons it often turns out to be the worse of the two.

Paying for a petrol-in-diesel drain around Somersham

One number would not be fair here, because this isn't one job. These are the things that shift it:

  • This is the main one: whether the engine has been started, or driven.
  • How much of the wrong fuel went in, against how much the tank takes.
  • Which went in: unleaded or AdBlue.
  • Access: the car's position, and whether working on it there's sensible for a van.

A clear answer instead of a range is what you get for telling us three things: your car, the quantity, and if it has run. Motor at home, going nowhere, nothing time-critical about it — is ideal for that.

Petrol in diesel queries from Somersham drivers

I am on a forecourt around Somersham. Can you drain the car on the spot?

Yes — forecourts are where a fair share of this happens. Regularly, provided the site agrees: Shell, plus every other forecourt nearby. Say on the phone where precisely you have stopped. Whether our technicians can work in that spot is something our engineers answer straight away.

How much petrol in a diesel is too much?

It rests on the ratio instead of the litres, and far more on whether your engine has run. An almost empty tank with five litres in it, against a full one with the same five: distinct scenarios, of course. Either way, the work needed comes down to one thing, which is if your fuel system has had that mixture sucked through it.

I drove it after putting petrol in my diesel. What next?

Stop safely. Off. Nothing after that. Not restarting it is the single most useful thing available to you now. Driving does shift the issue out of the tank and into your pump and injectors, yes, and it remains fixable far more frequently than people assume.

Is a fuel drain going to void my warranty?

No. Carried out properly, emptying and purging is no change at all, and the warranty from your manufacturer is untouched by it. Running a diesel on petrol is the thing likelier to cause a disagreement with one, which is another good reason to leave the vehicle switched off.

Adding two-stroke oil, then driving home

No. It belongs to a separate issue from a different era, and petrol has diluted something no oil of that kind replaces. Later? Still petrol in that tank, and a pump that has to put up with the stuff.

Main dealers and petrol in a diesel

There is no need to bring it to a main dealer, because our engineers drain and flush the car wherever it is.

You, and the vehicle, still together?

Never turn your engine on again.

If you have already driven it, pull over somewhere safe, turn it off then leave it off. Cold, parked, going nowhere: that's the best position to be in. Drivers fear this a lot more than they need to.

At the kerbside, on the forecourt or at home — mobile fuel draining around Somersham and across Suffolk.
