Abbey Hey: Put Petrol in a Diesel Car?
With that tank still carrying the fuel and the engine not yet started, nearly every job takes only a drain, so keep the motor off. That result is settled in the minutes right after filling up, rather than by the amount that got in. All over Abbey Hey and the rest of Greater Manchester, Petrol in Diesel drains the car and cleans it where it is, whether at a roadside, on a driveway or at a forecourt. Phone before all else begins, so you'll see what happens next.
Petrol in a diesel: what to do next
- Feed a petrol engine diesel and it will normally fail to run at all, so the person stops there and so does the wear. Feed a diesel petrol and the thing starts, it ticks over, it moves off — fine for several miles. Most people have that muddled, which is the thing they get wrong about petrol in a diesel in particular. So never start it. And having started, do not depend on it: the fuel system is grinding whenever you drive.
- Flicking your ignition on frequently primes the system, and priming is what moves petrol out of that tank then into your pump and injectors. Those are the parts diesel keeps protected on its way through, before it burns. Petrol does the burning and none of the protecting. Leave your ignition off.
- That advice assumes a diesel fuel system copes with petrol by percentage. It does not. Put diesel on top and nothing at all is removed; what you get is a bigger tank of the same mixture. And no, the grade makes no difference — super unleaded is just petrol.
- A motor that has not shifted is the easiest one to deal with, so stay where you are if you safely can. Stopped on the verge on Midgley Avenue? Hazards on, and leave the vehicle there. A difficult location suits us better than a started diesel.
- Check where you are before calling. A postcode starting M18 8, and the name of whatever is nearest to you. Otherwise the technician circles instead of turning up.
- Three replies decide the full call-out: the liquid you poured in, the ballpark volume of it, and whether it has been turning since. The number is 0333 366 0103.
On the forecourt: clearing petrol from the diesel
The work kicks off at a pump, mostly. Frequently the work ends at one too. The drain usually happens there and then. Still on the forecourt at Shell? Given the station's consent, that's a spot we work, and regularly.
A forecourt is the one setting the mistake can be spotted before your motor has fired. Fuel pulled out of your tank and through the filter, right to the high-pressure pump, is what occurs when the engine is fired up and your car is driven to where it is now: the car park, the driveway or the lay-by, anywhere other than the forecourt. So the flush includes the fuel filter and the fuel lines together with that tank. That is still not a catastrophe, and our technicians put it right where the vehicle is. What determines it is whether the ignition was reached for in the seconds after the till receipt was checked.
Move it out of the way if the attendants offer, and they generally will. The next driver gets through the petrol pump, and that is worth doing. Four vehicle lengths is not worth a start.
Simple, these ones, and the reason is the mileage: a mile at light throttle pulls very little fuel. Petrol into a diesel Renault Megane somewhere around Abbey Hey, a boot loaded with shopping, and you stuck outside Openshaw Superstore — phone us. Exiting that spot isn't worth another start. Your tank gets emptied where it waits, the lines rinsed, new diesel in, and you get home.
Your diesel Peugeot 308 will have seemed entirely normal on the way back from Abbey Hey Primary Academy. They do, and that's the snag with petrol in a diesel and not the other way round. Put diesel in a petrol motor and it usually will not run, so the driver stops and the wear stops with them. Put petrol in a diesel and it starts, idles and moves off as though nothing has happened — all while the high-pressure fuel pump does its work without the protection your fuel is meant to be providing. Nothing tells you, as from the driver's seat there's nothing to alert you about. Call us with roughly how far you travelled and how hard you pushed it; the second answer matters more than the first.
Pull over somewhere safe, switch off then phone us. Normal on the way out to Parkstone Park, flat on the way back? Then look at your tank. Petrol dilutes diesel; weaker fuel slips past the tightly fitted parts that build injection pressure; and the farther the diesel Mercedes C-Class travelled, the less of that pressure it held.
Pulled off the forecourt, read the receipt, and left the diesel Dacia Duster up close to Abbey Hey/High Bank Crown Green Bowls Club a few hundred yards later? That is about as well as this goes once the engine has turned. Ring us and leave the vehicle off. The short distance really helps, but it was still a start and a drive, and so diluted fuel has reached the fuel filter and your pump — which is why our engineers flush the lines instead of only draining your tank.
That deadness is your fuel failing to build pressure fully, not your engine failing — and with no warning for it, vehicles in that position normally get driven again before anybody phones. Please don't. A couple of streets is all it got: throttle gone soft, idle turned uneven, and a diesel Vauxhall Astra now sitting near St. Paul's with St. John's United Reformed Church. Turn it off then phone us.
Areas our vans cover near Abbey Hey
As a small village, Abbey Hey sees a steady visit, whilst the villages close by go along on that same run: Debdale and Openshaw, Gorton and Droylsden, Belle Vue.
There are separate pages for nearly all towns around Greater Manchester, and the ones listed above are merely the immediate neighbours — so yours being missing from the list means nothing whatsoever about whether our technicians come. Near the boundary, or somewhere your satnav misreads? Ring us to check instead of guessing.
The map marks the ground this page includes. The lot is territory our engineers work: a kerbside, a forecourt, a driveway, a car park. You don't drive the car anywhere.
Stuck by the kerbside in Abbey Hey
Some drivers find no safe spot to pull in whatsoever. If you realised after setting off and landed by the verge on Wentworth Avenue, or in a lay-by somewhere with the hazard lights flashing, that is a routine call for us rather than an unusual one.
Fine there? Sit by it. Not safe? Climb out and clear of it. Do not fire up your motor to nurse it somewhere safer — a diesel running on petrol will often oblige, and every mile it obliges for is drawing the mixture further into the fuel system. Carrying on does the car far more harm than a van coming out to an awkward location, and that is no trouble for us.
Petrol in a diesel, but the car has gone
Here is where the local M60 comes into it — under a mile from Abbey Hey. It will often take you onto it, and some way along, before you feel a thing. Then it is some smoke, a lumpy idle and power draining away — not a neat stop. Misfilled diesels rarely give you one of those.
Take the first exit that is sensible, stop there, and do not start it to move it. On a longer run — anything near the under 5 miles to the nearest city — take it the mixture has been through the filter, your pump and the injectors, and tell us when you call. It affects what our engineers bring.
A little about Abbey Hey
Abbey Hey is a locality in Greater Manchester, situated near the lakeside and approximately 87 metres above sea level. Abbey Hey lies close to the city of Manchester, being around 3.6 miles from the city centre, and is near other local places such as Debdale, Openshaw, and Gorton. Abbey Hey has a population of around 5120 people and predominantly features terraced housing.
Our visit in Abbey Hey, step by step
- Our engineers establish what went in, how much, and whether the engine has run. The answers change the work, which is why our technicians ask before pricing.
- We drain the tank of the tainted fuel.
- Our engineers purge the fuel lines and clear the filter, so what's left in the system isn't what caused the trouble.
- The fuel system gets bled, on new diesel.
- Our engineers fire it up and confirm it runs correctly on clean diesel.
From there, you are ready to pull away. There is no need to go to a garage at any point, because the work is all done where the car is, and when it's caught early, long-term damage is very unusual.
A separate matter: AdBlue in a diesel tank in Abbey Hey
Don't fire it up: that first instruction holds whether what went in was AdBlue or petrol. What differs is this fault itself. Weakened diesel, and no lubrication left for your fuel system that relies on it. That is petrol. AdBlue? Urea dissolved in water. Put that in with your diesel and you get rust instead, plus deposits.
Both are ours. There's a separate Abbey Hey page for AdBlue removal, with the details on it — including the reasons it frequently turns out to be the worse of the two.
Abbey Hey costs for a petrol-in-diesel fuel drain
We cannot put one price on this page truthfully, because this job isn't one job. What moves it:
- This is the key one: whether your motor has been started, or driven.
- The tank's capacity, set against how much of the wrong fuel got into it.
- Which got in: unleaded or AdBlue.
- Where the vehicle is, and if our van can safely get to and work on it.
Tell us what your vehicle is, how much went in, and if your motor has run. A firm answer comes back, not a range. Vehicle at home, going nowhere, nothing time-critical about it — is ideal for that.
Petrol in diesel: common questions around Abbey Hey
Fuel drains on a Abbey Hey petrol station forecourt
Much of what we do gets done nowhere else. So yes. We work at Tesco and the other forecourts around town routinely, with the owner's agreement — tell us which one you're at when you call and we'll tell you if our engineers can work there.
A few litres of petrol in a diesel — too much?
It hinges on the ratio instead of the litres, and far more on whether your motor has run. What determines how much work is required is whether that blend has been sucked through your fuel system — because even though five litres in an almost empty tank is a distinct case from five in a full one, either way that is the query.
Already driven it with petrol in your diesel? Now what?
Stop sensibly. Off. Nothing after that. Not restarting it is the single most valuable thing available to you now. Driving does shift the problem out of your tank then into the pump and injectors, yes, and it stays recoverable far more often than drivers fear.
Fuel drains and manufacturer warranties
A drain then flush carried out correctly isn't a modification and does not cancel a manufacturer's warranty. Running a diesel on petrol is the thing more likely to cause a dispute with one, which is another reason to leave the vehicle switched off.
Two-stroke oil in your tank, and then home?
No. Two-stroke oil is an old workaround for a separate issue and it does not put back what petrol has thinned. Petrol remains in that tank afterwards, whatever else goes in, and the pump gets no break from it.
Does petrol in a diesel have to go to a main dealer?
No. Our technicians drain and flush the car wherever it is, so there is no need to take it to a dealership.
Standing next to it?
Leave the engine turned off.
Driven it already? Then somewhere sensible, stop, switch off, and no restarting the vehicle after that. This is recoverable from much more commonly than motorists assume, and a parked, cold vehicle is the best place to be in.
