Put Petrol in a Diesel Car in Barrowby? Don't Start It
Don't fire up the motor. If the petrol is still sitting in your tank and the motor has not run, a tank drain is nearly always all it needs — and that gets decided in the coming few minutes, not by how much went in. Petrol in Diesel drains and flushes wrongly fuelled cars where they stand, across Barrowby and the rest of Lincolnshire, on the forecourt, by the roadside or on a drive. Phone so our technicians can show you what comes next before you do much else.
Now what? Petrol in a diesel, in turn
- Give a petrol engine diesel and it will generally refuse to run at all, and so the motorist stops there and so does the damage. Feed a diesel petrol and the car starts, it idles, it pulls away — fine enough for a few miles. Drivers have that reversed, which is the bit they get wrong about petrol in a diesel specifically. So never crank it. And once started, never believe it: that fuel system is grinding while you drive.
- Diesel ignites, and before it burns it protects — the high-pressure pump, those injectors. Petrol handles only the burning. So leave the ignition alone too: flicking it on is often enough to prime that system, and priming carries petrol from that tank into just those parts.
- That advice supposes a diesel fuel system tolerates petrol by percentage. It will not. Add diesel on top and nothing at all is cleared; what you get is a bigger tank of the same blend. And no, the grade makes no difference — super unleaded is simply petrol.
- Stay put if it is sensible to. Hazards on, engine off, keep the vehicle. Wherever you have stopped — the verge on Main Street, anywhere — an awkward place for us trumps a started engine, and nothing is easier for us to deal with than a car that never moved.
- Before you ring, get your location. Anything closest to you with a label on it, plus a postcode beginning NG32 1 — that's what determines whether our van shows up or circles.
- Phone 0333 366 0103. Prepare for three things — what got in, approximately how much, and if the motor has been started. Those answers shape whatever happens next.
Can petrol be taken out of a diesel at the forecourt?
Much of this job begins at a forecourt, so a big chunk of that gets done there. If you're still on the forecourt at Asda, that's normally where this drain gets done — we work on station forecourts routinely, with the site's agreement.
At a forecourt, it gets spotted with the engine never started, and no place else does it. Everywhere else — a car park, a drive, a lay-by — your car was started and driven to get there, which means fuel was sucked from your tank, through your filter and into the high-pressure pump. That is not a calamity, and our engineers can still deal with it where it is. It does mean the lines and the fuel filter need rinsing as well as the tank, and that is settled by the few seconds between checking your receipt and reaching for your key.
Roll the vehicle out of the way if the staff offer, and they usually will. The next motorist gets past the petrol pump, and that is worth doing. Firing it over four vehicle lengths? Not a chance.
Parts our vans serve around Barrowby
Barrowby is a rural village, so our technicians get out to the town and to the places near it on the same rounds: Beeden Park, Earlesfield, Great Gonerby, Gonerby Hill Foot and Sedgebrook.
There are pages for the majority of locations around Lincolnshire, and the ones listed above are simply the closest neighbours — so yours being missing from the list means nothing at all about if our engineers come. Phone to check instead of guessing — borders especially, and wherever your phone tends to get wrong.
Use our map for the area included on this page. Kerbside, forecourt, private drive, car park: the lot is territory our engineers serve, and none of that needs the car to come to us.
Barrowby: stuck where you stopped
Not everyone has a chance to stop somewhere sensible. If you noticed after setting off and ended up by the verge of Rectory Lane, or in a lay-by somewhere with the hazards on, that's a common call for us instead of a rare one.
Whether you stay with the vehicle or stand away from it rests on whether sitting in it looks safe. Don't restart your motor to nurse the car somewhere better — a diesel running on petrol will usually oblige, and every mile it obliges for is pulling the blend further into the fuel system. A technician heading to an inconvenient place is no problem for us, and it's a lot better for your car than pressing on.
It will start. It will drive off perfectly well. That is the issue, because a diesel on a weakened tank acts generally whilst wearing down the components its fuel should be lubricating. So no, don't chance the trip home from The White Swan — leave the Mercedes C-Class and phone.
Nothing gets worse whilst it waits. Whatever your diesel Peugeot 3008 did on the way to Stubbock Hill, it is doing none of it now: your pump isn't turning. So take your time — but don't drive the vehicle home to buy yourself any.
Draining the Audi A3, changing the fuel filter where there's a usable one, rinsing the fuel lines, putting clean fuel through the whole circuit: that's this job, and it is shaped by the worst of it resting in the fuel lines instead of in that tank by this point. Three things help when you ring from close to Barrowby Reading Room — which side the filler is on, whether our van can pull up beside without blocking the road, and if the engine has run since you filled up. On-street is the usual location our technicians work, so the spot itself is seldom the problem. A cramped parking spot trumps a car driven somewhere more handy.
Hire car? Company car? Ring them before us. Some contracts want the firm to sign off the work, and that's much faster dealt with up front than after that. Then call us about the BMW 1 Series, the diesel one, near All Saints. Don't worry that you can't say how full your tank was — almost nobody can two days into a car, and it is something our engineers establish on site. The reason for asking: damage from petrol in a diesel is a matter of share. A few litres in a nearly empty tank make a far stronger mix than in a full one, and petrol is built to resist the very thing a diesel needs of it, which is igniting when compressed. Stronger blend, more knocking, more smoke, flatter throttle.
Fixed and starting are not the same thing, and the difference is your circuit: our engineers flush it, and take your filter off where there is a working one. Compare that with the confident suggestion you'll get — drain the car, refill with clean diesel. Half right. Do precisely that to a diesel Vauxhall Astra by Barrowby Sports Pavillion and it'll start, which is exactly why the tip sounds reasonable. Then the motor pulls the petrol left behind in the fuel filter, and in the feed lines, straight back through the pump, as emptying a tank does nothing whatever about fuel that has already left it. Ring us instead.
A few miles on petrol in a diesel: what next?
Here is where your M1 comes in, under 25 miles from Barrowby. Lost power, a rough idle, some smoke: those are the signs when they arrive, instead of a neat stop — and a misfuelled diesel will often take you onto it and some distance along before anything seems wrong at all.
Take the first junction that is safe, pull up there, and never start the vehicle to move it. Long trip? Anything close to the under 25 miles to the nearest city and you should presume the lot — filter, pump, injectors, all of it got to by the mixture. Say that on the call, because it affects what goes in our van.

Once our engineers arrive with you around Barrowby: what follows
- Our technicians find out what got in, how much, and if the engine has run. The replies alter the work, which is why we ask before quoting.
- Away goes the contaminated fuel.
- Fuel lines are cleaned through and the filter cleaned, leaving nothing in your system that caused any of this.
- Our technicians put clean diesel in and prime your system.
- It is started with clean diesel in it, and we check that it is running smoothly.
Then it's ready to drive away. We do all of this wherever the vehicle has stopped, which means it never needs to go to a workshop, and if it has been spotted soon, it's very rare for there to be lasting damage.
AdBlue in your diesel tank by mistake, around Barrowby?
If what went in was AdBlue rather than petrol, the first instruction is unchanged — do not start the vehicle — yet the problem isn't. Petrol does two things to diesel: weakens it, and takes away the protection your fuel system relies on. AdBlue? Urea dissolved in water. Tip that in with the diesel and you get corrosion instead, plus deposits.
We deal with both, and AdBlue removal around Barrowby has its own page with the full story — including why it's usually the more significant of the two.
What a petrol-in-diesel drain costs around Barrowby
What changes the price is set out below, because the job isn't one job and our engineers cannot honestly put a single number on this page.
- Started? Driven? Either answer counts more than anything else on this list.
- How much of the wrong fuel was put in, against how much the tank holds.
- AdBlue or petrol, whichever went in.
- Whether a van can safely reach your car and work on it, which hinges on where your car is.
A straight answer rather than a range is what you get for telling us three things: the vehicle, the quantity, and if it has run. Car at home, going nowhere, nothing pressing about it — is fine for that.
Barrowby motorists ask us these about petrol in diesel
Fuel drains on a Barrowby petrol station forecourt
Plenty of what our engineers do happens nowhere else. So yes. Our engineers attend Esso and the other forecourts around town regularly, with the site's agreement — tell us which one you are at when you phone and we'll tell you if we can work there.
A few litres of petrol in a diesel — too much?
Litres are not the measure. Proportion is, and a lot more than either, it counts whether anything has been run. Five litres in an almost empty tank is a different case from five in a full one — but either way, the thing that settles how much work is needed is if that blend has been sucked through the fuel system.
I put petrol in my diesel and drove the vehicle. Now what?
Switch off somewhere safe, and keep it that way after you stop. Driving is what moves the issue from that tank into your pump and injectors — but it is fixable much more frequently than drivers expect, and the single most useful thing you can do now isn't restart it.
Will a fuel drain void my warranty?
It isn't an alteration, and so a drain and flush carried out properly doesn't invalidate a manufacturer's warranty. Another good reason to leave it turned off: running a diesel on petrol is the thing more likely to cause a dispute with one.
Could I put some two-stroke in and just drive?
No. Two-stroke oil is an old workaround for a different fault and it does not put back what petrol has weakened. The pump still has to cope with it, as that tank still has petrol in it afterwards.
A main dealer for petrol in a diesel — essential?
There's no need to bring it to a main dealer, since our technicians drain and clean the car wherever it is.
Waiting next to it?
Shut off is how the car remains.
Turn it off somewhere safe then keep it off, if you have already driven it. A still, cold motor is the best place to be in, and this is recoverable from far more commonly than people assume.
