High Town: Put Petrol in a Diesel Car?
Petrol in Diesel drains and flushes wrongly fuelled vehicles where they sit, on the forecourt, by the roadside or on a private drive, across High Town and the rest of Nottinghamshire. The very first thing to do is not to fire up your engine. While your engine has not yet been started and the petrol is still sitting in your tank, a drain is almost always all it takes, and the next few minutes decide that, not how much got in. Our team will tell you what the next part will be. Contact us — that happens before everything else.
The next five steps: petrol in a diesel
- While you drive, the pump and the fuel injectors wear down. This is why you don't crank it, and why you don't rely on it once it has started. The thing about petrol in a diesel in particular — the part motorists get wrong — is that it drives off normally for the first mile or two. Diesel in a petrol engine usually cannot run at all, which stops the driver and stops the damage with them. This one lets you keep going.
- Leave the ignition be also. Diesel performs two tasks: it combusts, and before it ignites it greases the high-pressure pump and those injectors. Petrol manages the first but not the second. Flicking the car's ignition on is usually all it takes to prime your system, which draws that petrol out of your tank and into precisely those parts.
- Don't water down it. Diesel tipped on top gets rid of nothing, so all you get is more of what was already there, because percentage is not how a diesel fuel system accepts petrol. Super unleaded? Simply petrol. The octane makes no difference.
- We'd much rather travel to an awkward spot than have it started — so if you reasonably can, sit tight. Nothing is quicker to handle than a motor that has not moved. On the verge on Halam Road, that means hazards on and keep the car.
- Keep your location prepared before you phone. A postcode that starts NG25 0 and whatever is next to you with a name on it is the difference between the van showing up and a van circling.
- What went in, about how many litres, plus whether your car has fired — these three facts decide your whole visit. Phone 0333 366 0103 then tell us.
Forecourt draining for petrol in a diesel
Much of the work starts at a forecourt, meaning a fair chunk of that ends up done on site. Still at BP? Then that is typically where it gets done. Petrol station forecourts are everyday for us, with the consent of the owner.
The forecourt is the one location it gets stopped before your motor has started. 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 that tank, through your filter and into the high-pressure pump. That's not a disaster, and our technicians can still deal with it where it stands. It does mean the fuel lines and the filter need cleaning as well as the tank, and that is determined by the few seconds between checking the receipt and reaching for the keys.
The staff will usually help you roll the car clear of the pump so the next customer can get through. That's worth doing. Rolling it four spaces doesn't merit cranking the motor.
The difficult part is the bay, not your fuel. Cars either side of you, a trolley shelter behind, and now and then a height limit on the way in that settles whether a technician can reach you at all — so when you phone from a car park like the one outside Co-op Food, mention how much space there is around you and which way round your car is. Those our engineers visit frequently. Should there be no room to work beside the diesel Audi A4, it gets rolled with the motor off, and not out of pedantry over a couple of seconds of running: priming occurs at every start, more of the mix departs the tank for your pump, and two shunts into a better space have silently made a harder job of what was just a motor sitting still.
You will be advised to shift it clear of the gateway and deal with it later. Do not. On the zig-zags at Lowe's Wong Infant School, a misfuelled Ford Focus running on diesel is in the way, and that's all it is. Start it three more times being helpful and you have turned a tank into a fuel system: every start primes your lines, every prime draws more petrol beyond your filter toward the pump. Let them grumble. Phone.
Park it overnight. Phone first thing. Nothing about a diesel Mercedes C-Class standing in the parking area at Admiral Rodney degrades as it stands, tank of petrol or not, and the job remains an easy one right up until the moment it gets taken home. The question our engineers come with is about that run there: a cold motor over a short distance is where petrol combusts least well, and whatever fails to burn can find its way past the piston rings into the engine oil.
Out there fine, back gutless. If that was the drive to Lodge Plantation, look at the tank. Diesel gets thinned by petrol, and thin fuel seeps past the tight gaps supposed to build injection pressure — so every additional mile your diesel Dacia Duster covered, the less pressure it held onto. Somewhere sensible, turn off, call us.
Why so firm about leaving your keys alone? Since the pump is before your injectors, and a worn-out one sends whatever it sheds on with the fuel. Ring us. Leave the BMW 5 Series near Our Lady Of Victories.
Parts our vans serve near High Town
The same runs take us to Southwell, Westhorpe, Maythorne, Easthorpe and Normanton besides High Town, which is a residential suburb.
There are separate pages for most locations around Nottinghamshire, and the ones mentioned above are simply the closest neighbours — so yours being absent from this list means nothing about whether we come. Call us and check rather than presuming — boundaries especially, and wherever your satnav can get wrong.
That map shows the area the page spans. The vehicle does not need to travel to us. We work throughout the lot — kerbside, forecourts, driveways, car parks.
Stuck by the roadside in High Town
Not everybody gets the chance to pull over anywhere suitable. If you noticed after setting off and finished up on the verge of Chatsworth Avenue, or at a lay-by somewhere with the hazard lights flashing, that is a routine call for us and not a rare one.
Whether you sit by the motor or stand away from it hangs on if sitting nearby seems sensible. Every mile a diesel obliges you for on petrol drags the mixture further into your fuel system — and oblige it usually will, which is why the engine doesn't get restarted to limp somewhere safer. However inconvenient the spot, it's no problem for us to get to it, and that is a lot better for your car than driving on.
A couple of miles on petrol in a diesel: what now?
This is where the M1 comes in, under 15 miles away from High Town. Some way along, and onto it in the first place: a misfilled diesel will frequently do both before anything seems wrong. What you get then is seldom a neat stop. Power ebbs away, the idle turns lumpy, and there may be some smoke.
Take the next junction that is safe, pull up there, and don't start it to reposition. Long drive? Anything close to the under 15 miles to the nearest city and you should presume the lot — filter, pump, injectors, all of it arrived at by the mixture. Say that on the call, since it changes what goes in our van.
All about High Town
High Town is a suburban area located on the riverside in Nottinghamshire, with an elevation of around 45 metres. High Town sits near the city of Nottingham, approximately 11.6 miles away, and is close to nearby places such as Southwell, Westhorpe, and Maythorne. High Town has a population of around 3616 people and is characterised by predominantly detached housing.
What we do when we arrive with you in High Town
- Three things get checked before any price — your fuel that got in, the quantity, and whether anything has been run since. Each answer alters the work.
- The polluted mixture comes out of the tank.
- Fuel lines are rinsed through and the fuel filter cleaned, leaving nothing in the system that caused any of this.
- Bleeding the system follows, once new diesel is in.
- It's fired up with clean diesel in it, and our technicians check that it's running smoothly.
Your car is then ready for you to pull away. There's no need for a garage at any point, since the work is all done where your car is, and when it's noticed soon, permanent damage is very unusual.
AdBlue in a diesel tank in High Town is a distinct matter
The problem isn't the same, though the first rule is — don't crank it — if what went in was AdBlue rather than petrol. Thinned diesel, and no lubrication left for the system that depends on it. That's petrol. Corrosion and deposits are what a diesel tank ends up with instead, since AdBlue is urea dissolved in water.
Both are ours. There's a separate High Town page for AdBlue removal, with the full story on it — including the reasons it frequently turns out to be the worse of the two.
Budgeting for a petrol-in-diesel fuel drain in High Town
One number wouldn't be honest here, since this isn't one job. These are the things that change it:
- Has it been started or driven? Nothing else counts for as much.
- How much of the wrong fuel went in, compared with how much the tank takes.
- Whether it was petrol or AdBlue.
- Whether a technician can sensibly reach the car and work on it, which hinges on where the car is.
The vehicle, the amount, whether it has run — give us those and the answer comes back clear instead of as a range. If it is not pressing — the vehicle is at home and going nowhere — works too.
Questions our engineers get about petrol in diesel around High Town
Fuel drains on a High Town petrol station forecourt
Yes — forecourts are where a big portion of this happens. Our technicians work at Gulf and the other forecourts around town all the time, with the station's permission — tell us which one you are at when you call and we will tell you if our technicians can work there.
A few litres of petrol in a diesel — too much?
It hinges on the proportion rather than the litres, and a lot more on whether your engine has run. An almost empty tank with five litres in it, against a full one with the same five: different scenarios, certainly. Either way, the work required comes down to one thing, which is whether your fuel system has had that mix drawn through it.
Already driven it with petrol in the diesel? Now what?
Pull in somewhere sensible, switch off, then leave it off. Not restarting it is the single most helpful thing available to you now. Driving does shift the issue out of that tank then into the pump and injectors, yes, and it remains recoverable much more often than drivers assume.
Fuel drains and manufacturer warranties
It's not an alteration, and so a drain then flush carried out correctly doesn't invalidate a manufacturer's warranty. Running a diesel on petrol is the thing likelier to cause a dispute with one, which is another good reason to leave it switched off.
Can I just add two-stroke oil and drive home?
Two-stroke oil solves a separate issue, and an old one at that. Nothing it does puts back what petrol thinned. 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
You do not need one. The car is drained and cleaned wherever it is, with no need to bring it to a main dealer.
Is your vehicle still with you?
Never switch it on again.
Driven it already? Then somewhere safe, stop, switch off, and no restarting the car later on. Cold, parked, going nowhere: that's the best place to be in. Drivers fear this a lot more than they need to.
