Put Petrol in a Diesel Car in South Harting? Don't Start It
Petrol in Diesel drains and flushes misfuelled cars where they are, on the forecourt, at the roadside or on a driveway, throughout South Harting and the rest of West Sussex. The very first thing to do is not to fire up the engine. When the engine has not run and the fuel is still in that tank, a tank drain is nearly always all it requires, and the following few minutes settle that, not how much was put in. Contact us and our team will show you what comes after that before you do any more.
The next five minutes: petrol in a diesel
- As you drive, the pump and the fuel injectors suffer. That is why you don't start the vehicle, and why you don't trust it once it has started. The trick about petrol in a diesel especially — the bit drivers get wrong — is that it drives off happily for the first mile or two. Diesel in a petrol engine normally will not run at all, which stops the motorist and stops the wear with them. This one lets you drive on.
- Leave the car's ignition be too. Diesel does two roles: it ignites, and before it burns it protects that high-pressure pump and those injectors. Petrol does the first and not the second. Flicking the ignition on is often sufficient to prime the system, which pulls this petrol out of that tank then into just those components.
- Topping up removes nothing. It gives you a bigger tank of the same mixture, because a diesel fuel system won't cope with petrol by percentage in the way that advice implies — so don't put diesel on top to weaken it. Grade is immaterial too: super unleaded is petrol.
- Sit tight if it's wise to. Hazards on, engine off, leave the car. Wherever you have stopped — the verge on B2146, anywhere — a tricky location for us beats a started motor, and nothing is simpler for us to sort than a motor that never shifted.
- Before you dial, work out your position. Anything closest to you with a name on it, plus a postcode that starts GU31 5 — that's what decides whether the van turns up or circles.
- Three facts decide the entire call-out: the fuel you tipped in, the ballpark volume of it, plus whether it has been turning since. The line is 0333 366 0103.
The journey back would close to double it, for no gain at all. One commute has already put a real amount of petrol-thinned diesel through the high-pressure fuel pump of that Volkswagen Passat. So leave the vehicle where it sits. Ring us from the platform if that's handier — no one needs you hovering over the car at Petersfield while we get on, and tonight beats finding out on Monday.
Tell us this much and we can work with it: a diesel Renault Clio, a couple of litres of unleaded in it, two miles or so, switched off outside M&S Foodhall now. Time passed isn't the thing our engineers need. Fuel sucked by your pump is.
Pull over somewhere safe, turn off then phone us. Normal on the way out to Torberry Copse, flat on the way back? Then look at your tank. Petrol thins diesel; weaker fuel slips past the close-fitting parts that build injection pressure; and the farther the diesel Mercedes C-Class went, the less of that pressure it held.
Why so blunt about leaving your keys alone? Because your pump is ahead of the injectors, and a wearing one sends whatever it gives off on with the fuel. Ring us. Leave the Dacia Duster close to St Mary & St Gabriel.
The fuel filter, the fuel lines, the pump and its rail: that's where that mix is once a diesel has run, and it doesn't come back out with that tank contents. So the tank is not where most of the trouble rests by this point, and a diesel Ford Kuga that made it by South Harting Sports Pavilion needs your circuit purged instead of emptied.
On the forecourt: removing petrol from your diesel
A big part of the job gets completed at a forecourt, since that is where it mostly begins. The drain normally takes place there and then. Still on the forecourt at Texaco? Given the station's agreement, that is a spot our engineers work, and regularly.
Nowhere else other than a forecourt can the mistake be halted with your engine still unstarted. The few seconds between checking your receipt and going for the keys settle how much needs rinsing. Everywhere other than the forecourt — a car park, a driveway, a lay-by — the vehicle was fired up and moved to get there, so fuel was pulled from that tank, through your filter and into your high-pressure pump. That means the fuel lines and your filter require flushing as well as the tank. It is not a catastrophe, and our engineers can still put it right where your car stands.
The attendants will generally offer to wheel the vehicle clear of the petrol pump so the next driver can get past. It is worth doing. Rolling the car four spaces doesn't justify starting the motor.
Do our technicians reach your side of South Harting?
East Harting, West Harting, Old Ditcham, Nyewood, Nursted — each of those on the rounds that take us across to South Harting itself, a rural village.
Not on this list? It says nothing. The names above are just the closest few, and the majority of towns across West Sussex have a page of their own somewhere on this site. Phone to ask instead of presuming — borders above all, and wherever a satnav tends to struggle with.
This map is the ground the page spans. All of that is ground our technicians work: a kerbside, a forecourt, a drive, a car park. You don't drive the vehicle anywhere.
Roadside call-outs across South Harting
Not everyone gets a safe place to pull in. Hazards going at a lay-by somewhere, or stopped on the verge on North Lane since you realised after setting off — we take that call often enough that it is the normal kind.
Clear of the vehicle when it's not sensible to be inside, with it when it is. Every mile a diesel obliges you for on petrol pulls the mix further into your fuel system — and oblige it usually will, which is why the motor does not get restarted to limp somewhere safer. A technician coming to a tricky location is no bother for us, and it is a lot better for your car than driving on.
Petrol in a diesel, and the vehicle has travelled
The Waterlooville Bypass is the one that counts now, and lies under 10 miles from South Harting. A loss of power, an uneven idle, smoke: those are the signs when they arrive, instead of a clean stop — and a misfilled diesel will usually get you onto it and some distance along before anything feels wrong at all.
Do not start it to move it. Get off at the next safe junction then turn off. On a longer drive — anything near the under 15 miles to the closest city — assume the mixture has been through the fuel filter, your pump and the fuel injectors, and say so when you call. It changes what we bring.

South Harting lies approximately 10 miles north of Chichester and 49 miles south-west of London, with the village of East Harting nearby. South Harting has a population of around 1154 people, predominantly living in detached houses. South Harting is surrounded by rolling countryside and woodland, characteristic of the South East region.
Once our technicians arrive with you in South Harting: what follows
- Our engineers find out what went in, how much, and whether your engine has run. The answers shape the work, which is why our engineers ask before pricing.
- The tank gets drained of it.
- Lines rinsed, filter cleaned. Whatever remains afterwards is not the thing that created the problem.
- Clean diesel goes in, and then the system gets primed.
- It is fired up with new diesel in it, and our engineers check that it is running properly.
After that it is ready to drive away. There is no need to go to a garage at any stage, as the work is all done where the car is, and when it is caught soon, permanent damage is very rare.
AdBlue in a diesel tank around South Harting is a distinct matter
AdBlue rather than petrol? Then the first instruction is unchanged — the engine stays off — while this problem under it's a distinct one altogether. Petrol dilutes your diesel and strips the lubrication the system depends on. AdBlue is urea dissolved in water, and in a diesel tank it brings corrosion and residue in its place.
Both are ours. There's a separate South Harting page for AdBlue removal, with the details on it — including the reasons it often turns out to be the worse of the two.
How much is a petrol-in-diesel drain in South Harting?
Our engineers cannot put one price on this page honestly, since the job is not one job. What changes it:
- Whether your engine has been run or driven. This is the big one.
- The tank's capacity, set against how much of the wrong fuel got into it.
- Which got in: petrol or AdBlue.
- Where the vehicle is, and if a technician can safely get to and work on it.
A firm answer instead of a range is what you get for telling us three things: the vehicle, the amount, and whether it has run. Not time-critical, with the car at home and going nowhere? Then works.
Petrol in diesel queries from South Harting motorists
Fuel drains on a South Harting petrol station forecourt
Yes, and it is where a good share of this work takes place. Tell us which one you're at when you phone and we'll tell you if we can work there. With the station's permission we visit Esso and the other forecourts locally routinely.
Is there a safe amount of petrol in a diesel?
Ratio settles it instead of litres — and more than either, whether the motor has run. Five litres in a nearly empty tank is a separate matter from five in a full one — but either way, the thing that decides how much work is needed is if that mixture has been pulled through the system.
I put petrol in my diesel and drove it. What now?
Stop somewhere sensible, switch off, and leave the car off. Not restarting it is the single most valuable thing available to you now. Driving does shift the problem out of that tank then into your pump and injectors, yes, and it remains recoverable much more commonly than drivers expect.
Is a fuel drain going to void my warranty?
It isn't a modification, so a drain then flush carried out properly doesn't invalidate a manufacturer's warranty. Running a diesel on petrol is the thing more likely 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?
What petrol has weakened isn't restored by two-stroke oil, which is an old workaround for a separate fault. So no. Your pump still has to cope with it, since your tank still has petrol in it after that.
A main dealer for petrol in a diesel — essential?
There is no need to take it to a main dealer, since our engineers drain and clean the vehicle wherever it is.
You, and the vehicle, still together?
Shut off is the way the car remains.
If you have already driven the vehicle, stop somewhere sensible, switch it off and leave it off. A still, cold vehicle is the best place to be in, and this is recoverable from much more regularly than people expect.
