Boulder Hill: Put Petrol in a Diesel Car?
If you have not fired up the motor yet, don't. A fuel drain and nothing more is almost always what a car needs while the fuel is still sitting in the tank and the motor has not run, which is why it is the next few minutes that count, not how much got in. Petrol in Diesel comes to the vehicle wherever it has come to rest in Boulder Hill or the remainder of South Yorkshire, on the forecourt, by the roadside or on a drive, and drains and cleans it there. Phone and then our engineers shall show you what follows next before you try anything else.
What to do now about petrol in a diesel
- Do not crank it. Turned on anyway? Then do not believe it. Diesel in a petrol car generally won't run, and so the person stops and the wear stops with them. Petrol in a diesel? It starts. It idles. It pulls away happily, for a couple of miles. Motorists get that reversed. It is not all right — your fuel system is wearing down every mile you drive.
- Switching your ignition on often primes your system, and priming is what carries petrol out of your tank and into your pump and injectors. Those are the parts diesel keeps protected on its way through, before it ignites. Petrol manages the burning and none of the oiling. Leave your ignition off.
- Never tip diesel on top to thin it. A diesel fuel system won't cope with petrol by percentage as that advice suggests, and topping up clears nothing — it merely leaves you a larger tank of the same blend. The octane makes no difference either: super unleaded is just petrol.
- Stay put if it's safe to. Hazards on, ignition off, leave it. Wherever you have stopped — the verge on Greenock Street, anywhere — a difficult place for us is better than a started engine, and nothing is quicker for us to sort out than a car that never shifted.
- Have your location ready before you phone. A postcode that starts S6 4 and whatever is closest to you with a sign on it is the difference between a van turning up and the van circling.
- Ring 0333 366 0103. Anticipate three things — what was put in, approximately how much, plus if your car has been started. Your responses settle all that happens next.
Never take it home. Petrol-thinned diesel has run through the high-pressure fuel pump in real quantity on the road in, and the drive back would more or less double that for nothing at all. Phone — the platform is okay. There's no need to stand over that Volkswagen Golf outside Sheffield whilst the work goes on, and we'd much rather talk to you tonight than realise on Monday.
Car parks like the one outside Lidl are somewhere we work in frequently, and your fuel is rarely the awkward part. The bay is: cars either side, a trolley shelter behind, sometimes a height limit on the way in that determines if our van can get to you at all. So tell us how hemmed in you are when you ring, and which way the car is pointing. When our technicians can't work next to your diesel Renault Megane we'll roll it without running it — and that is not fussiness about a handful of seconds of running. Any start primes your fuel system and sucks more of that blend out of the tank and on to the pump, and so a car moved twice into a roomier bay has silently grown into a bigger job than one left precisely where it stopped.
Someone will urge you to shift the car out of the gateway and deal with it later. Do not. A wrongly fuelled diesel Audi A4 on the zig-zags outside Malin Bridge Primary School is a nuisance; the same vehicle started three more times to be helpful is a fuel system rather than a tank. Each restart primes your lines and draws more petrol through the fuel filter then into your pump. Leave it, let people moan, and give us a call.
A vehicle you collected two days ago gets driven further before anybody spots anything, which is the hire and courtesy fault in one sentence — and how far it went is what determines the volume of petrol reaching the fuel injectors. Nothing sloppy about the mistake itself: a modern diesel filler neck accepts the slimmer petrol nozzle with practically no resistance, so strange locations see most of these. Ring us from wherever you are, near St Polycarp's or not, and we will come to the BMW 1 Series.
Repaired and starting aren't the same thing, and the difference is your system: we flush it, and take the fuel filter off where there is a serviceable one. Compare that with the sure of themselves advice you'll get — drain the vehicle, refill with clean diesel. Half right. Do precisely that to a diesel Skoda Superb close to Sheffield Flood 1864 and it will start, which is precisely why the suggestion sounds sensible. Then the motor draws the petrol left behind in your filter, and in the feed lines, straight back through the pump, since draining a tank does nothing whatever about fuel that has already left it. Phone us instead.
On the forecourt: draining petrol from the diesel
Much of the job starts at a pump, so a big share of it gets finished at one. If you are still at the forecourt at JET, that's usually where this drain happens — we work on petrol station forecourts regularly, with the site's agreement.
At a garage, the mistake is stopped with your engine never started, and nowhere else manages that. Fuel sucked out of the tank and through the fuel filter, right to the high-pressure pump, is what occurs when the motor is started and the vehicle is moved to where it is now: the car park, the driveway or the lay-by, everywhere other than the forecourt. So the flush covers the filter and the lines as well as that tank. That is still not a disaster, and our engineers sort it out where your car is. What determines it is whether the ignition was reached for in the seconds after the till receipt was checked.
Staff will normally chip in pushing it out from the petrol pump, which lets the next motorist get past. Take the offer. Cranking it over four car lengths? Never.
Service in Boulder Hill
Being a residential suburb, Boulder Hill has a steady visit, whilst the places round about go along on the same round: Malinbridge and Loxley Bottom, Walkley Bank and Hallowmoor, Lower Walkley.
There are pages for nearly all places in South Yorkshire, and the ones named above are simply the immediate neighbours — so yours being left off the list says nothing whatsoever about whether our technicians come. Phone and ask instead of guessing, especially where you're on the border or anywhere your satnav misreads.
The area this page includes appears on our map. Your car does not need to move to us. We work throughout every bit of that — roadside, forecourts, driveways, car parks.
Stuck by the kerbside around Boulder Hill
Not everybody has a sensible spot to pull over. Hazards flashing at a lay-by somewhere, or stopped on the verge on Rippon Crescent since you realised after setting off — our engineers take that call so often that it's the normal kind.
Whether you sit beside the vehicle or stand away from it depends on whether sitting nearby feels wise. Every mile a diesel obliges you for on petrol pulls that blend further into the fuel system — and oblige it often will, which is why your engine doesn't get restarted to limp somewhere safer. Our van heading to a tricky spot is no bother for us, and it is a lot better for the car than carrying on.
Petrol in a diesel, but the car has moved
Here is where your M1 comes in — under 5 miles from Boulder Hill. A loss of power, a rough idle, some smoke: those are the signs when they come, instead of a tidy stop — and a wrongly fuelled diesel will usually get you onto it and some way along before anything seems wrong at all.
Do not start it to move it. Get off at the next sensible junction and turn off. It alters what our technicians bring, and so say so when you phone: on a longer trip — anything near the under 3 miles to the closest city — take it the mixture has been through the filter, the pump and the injectors.

What our technicians do when our engineers get to you in Boulder Hill
- Our engineers ask first, quote after. What got in? How much? Has your motor run? Those replies change what the work actually is.
- Your tank gets emptied of everything.
- Our technicians purge the lines and clean the filter, so what is remaining in your system is not what caused the issue.
- Our technicians pour clean diesel in and bleed the system.
- Your engine is turned on and checked to confirm it runs smoothly on fresh diesel.
From there, you are ready to set off. We do everything wherever the car has ended up, which means it never needs to go to a workshop, and when it has been noticed quickly, it is very uncommon for there to be long-term damage.
AdBlue in your diesel tank by mistake, around Boulder Hill?
The fault is not the same, though the first rule is — never crank it — if what was put in was AdBlue rather than petrol. Weakened diesel, and no lubrication left for the fuel system that depends on it. That's petrol. AdBlue? Urea dissolved in water. Put that in with your diesel and you get corrosion instead, plus residue.
Our technicians deal with both, and AdBlue removal in Boulder Hill has its own page with the full story — including why it's frequently the more significant of the two.
How much is a petrol-in-diesel fuel drain in Boulder Hill?
What changes the price is set out below, as this job is not one job and our technicians can't honestly put a single number on this page.
- Started? Driven? Either answer matters more than anything else on this list.
- The tank's capacity, set against how much of the wrong fuel went into it.
- AdBlue or petrol, whichever got in.
- Whether our van can sensibly reach the vehicle and work on it, which depends on where the car is.
The car, the amount, whether it has run — give us those and the answer comes back clear and not as a range. Motor at home, going nowhere, nothing time-critical about it — is ideal for that.
Things our engineers hear about petrol in diesel around Boulder Hill
At a petrol station in Boulder Hill, can you do a fuel drain there?
Much of what our engineers do happens nowhere else. So yes. Regularly, provided the site agrees: Morrisons, 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 there and then.
How much petrol is too much for a diesel?
Whether your motor has run matters a lot more, though the proportion counts too, instead of the litres. A nearly empty tank with five litres in it, against a full one with the same five: different scenarios, definitely. Either way, the work needed comes down to one thing, which is if the system has had that blend pulled through it.
Already driven it with petrol in the diesel? What now?
Stop safely. Off. Nothing after that. It is fixable a lot more regularly than drivers fear, even though driving is what moves the trouble from the tank into the pump and injectors — and the single most valuable thing you can do now isn't restart it.
Fuel drains and manufacturer warranties
A drain and flush carried out properly is not an alteration and does not void a manufacturer's warranty. What is likelier to start a dispute is a diesel that has been run on petrol. One more reason for the motor to stay off.
Adding two-stroke oil, then driving home
What petrol has weakened is not replaced by two-stroke oil, which is an old workaround for a distinct fault. So no. Petrol remains in that tank later, whatever else goes in, and your pump gets no respite from it.
Do I need a main dealer for petrol in a diesel?
Wherever your car is, our technicians drain and flush it there, so a trip to the main dealer does not come into it.
Still with your car?
Leave the engine switched off.
If you have already driven it, pull in somewhere sensible, turn it off then leave it off. This is recoverable from a lot more often than drivers expect, and a still, cold motor is the best place to be in.
At the roadside, on the forecourt or at home — call-out fuel draining around Boulder Hill and across South Yorkshire.
