Hawley: Put Petrol in a Diesel Car?
If you have not fired up the engine as yet, don't. A fuel drain and nothing else is nearly always what a motor requires while the petrol is still in that tank and the motor has not yet run, which is why it's the following few minutes that matter, not how much went in. Petrol in Diesel travels to the vehicle wherever it has come to rest in Hawley or the rest of Kent, on the forecourt, at the roadside or on a driveway, and drains and cleans it there. Call us before anything else happens, and you will learn what follows next.
What next? Petrol in a diesel, in turn
- As you drive, the pump and the fuel injectors wear down. This is why you never fire it up, and why you do not trust it once it has started. The catch about petrol in a diesel specifically — the bit most people get wrong — is that it drives away 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 damage with them. This one lets you keep going.
- Diesel ignites, and before it combusts it protects — that high-pressure pump, the injectors. Petrol manages only the burning. So leave your ignition alone also: switching it on is commonly sufficient to prime your system, and priming carries petrol from your tank into just those parts.
- Do not water down it. Diesel tipped on top gets rid of nothing, so all you have is more of what was already there, because percentage is not how a diesel fuel system tolerates petrol. Super unleaded? Just petrol. The grade makes no difference.
- Stay put if it is sensible to. Hazards on, motor off, keep it. Wherever you have stopped — the verge on Harold Road, anywhere — a tricky place for us trumps a started motor, and nothing is quicker for us to deal with than a car that never moved.
- Before you call, gather your whereabouts. Anything nearest to you with a label on it, plus a postcode starting DA2 7 — that's what decides whether the technician turns up or circles.
- Three facts settle the whole job: the fuel you tipped in, the rough amount involved, and if it has been going since. The line is 0333 366 0103.
Can petrol be pumped out of your diesel at the forecourt?
Pumps are where the work usually starts, and where a good chunk of that finishes. If you're still at the forecourt at Shell, that is usually where this drain gets done — we operate on garage forecourts all the time, with the owner's permission.
No place except a garage can it be caught with the motor still untouched. We can still sort it out where it stands, even away from the forecourt. In a car park, on a drive or in a lay-by, the vehicle has been started and driven there, and that sucked fuel through your filter and into your high-pressure pump, all the way from the tank. None of that is a disaster, although the flush then has to reach past that tank to the fuel lines and the fuel filter, and the few seconds between reading the till receipt and reaching for the key are what settle that.
Roll the car out of the way if the attendants suggest it, and they usually will. The next driver gets past the pump, and that's worth doing. Rolling it four bays doesn't merit starting the motor.
Any start primes your fuel system and pulls more of that blend out of your tank and toward the pump — which is why a vehicle moved twice into a roomier spot has gradually grown into a harder job than one left just where it stopped. So if we cannot work next to the diesel Renault Megane, our technicians roll the car without running it. None of that is fussiness about a handful of seconds of running. Car parks like the one outside Lidl we visit often, and your fuel is rarely the difficult part: the bay is. Motors either side, a trolley shelter behind, sometimes a height barrier at the entrance deciding whether a technician can reach you at all. Tell us how hemmed in you are, and which way the car faces.
Your pump isn't turning, and so whatever the diesel Peugeot 3008 did on the way to Hawley Clay Shooting Ground, none of that is going on now. Nothing is getting worse whilst it sits. Take your time over this — but never drive the car home to buy any.
We rinse your lines rather than only draining your tank, and the reason is that thinned fuel has already arrived at your filter and your pump: it was a start and a drive, however short. The hop really helps — pulled off the forecourt, receipt read, a diesel Audi A3 parked up close to Brethren's Meeting Room a couple of hundred yards later is about as well as this goes once the engine has turned. Call us then leave it off.
Authorisation first, where there is a hire firm or a company behind the car — some agreements demand it, and settling that beforehand saves a great deal of time later. After that, call us about the diesel Mercedes A-Class close to Faithful Christian Assembly. You will not know how full your tank was. Barely anybody does, two days into a motor, and it gets worked out on the spot anyway. We ask since the harm petrol does in a diesel is proportional: a couple of litres in a nearly empty tank make a much stronger mixture than the same few in a full one, and since petrol is built to resist igniting under pressure, which is exactly what a diesel relies on, the stronger it gets the more the motor knocks and smokes and flattens off.
Drain it then put new diesel in — that is the tip you will get, typically from somebody confident, and it's only half right. Do precisely that to a diesel Citroen C3 by St John the Baptist Church and it would start, which is what makes the suggestion sound reasonable. What occurs next is the trouble: the motor at once draws the petrol still resting in the fuel filter and the feed lines straight back through your pump, since draining a tank does nothing about fuel that has already left it. Ring us instead. Our engineers flush the circuit and take the filter off where the vehicle has a serviceable one, which is the difference between the vehicle being put right and your car only starting.
Coverage around Hawley
Sutton at Hone, Darenth, Brooklands, Clement Street, Wilmington — every one of them on the rounds that carry us over to Hawley too, a village.
We do come. Those places above are merely the immediate neighbours, and a page is there for nearly all places in Kent, so an absence from the list isn't an absence from the coverage. Ring us and enquire rather than assuming — borders particularly, and wherever your phone might struggle with.
The ground this page covers is on the map. We operate at the roadside, on forecourts, on driveways and in car parks over all of that, and the vehicle doesn't need to come to us.
Stuck on the kerbside in Hawley
Not everybody gets the opportunity to pull in anywhere safe. Set off, then noticed? Ended up along the verge on Alfred Road, or stuck in some lay-by with your hazards on? That's a common call here. Not an unusual one.
Clear of the vehicle when it is not wise to wait in it, by it if it is. Never fire it up to get to a safer location. It will go — a diesel on petrol usually obliges — and each mile of obliging drags the mix deeper into the fuel system. We'll send our van to a difficult location without any fuss, and for your car that is far better than carrying on.
So you've driven it? Petrol in a diesel after some miles
Here is where your M25 comes into it — under a mile from Hawley. It will usually get you onto it, and some way along, before you spot a thing. Then it's some smoke, a rough idle and power ebbing away — not a tidy stop. Misfilled diesels seldom give you one of those.
The first safe junction is the one to take. Switch off there, and leave the restarting alone. It changes what we bring, so tell us when you call: on a longer run — anything near the under 25 miles to the nearest city — assume the contamination has been through the fuel filter, the pump and your injectors.
A little about Hawley
Hawley is a village situated on the riverside in Kent, with an elevation of 33 metres above sea level. Hawley lies approximately 16.3 miles from London and is near several other settlements, including Sutton at Hone, Darenth, and Brooklands. Hawley has a population of around 1059 people and is characterised by semi-detached housing. Hawley is located in a commuter belt, with London being the nearest major city, about 15.1 miles away.
What happens when we get to you around Hawley
- We check what was put in, how much, and if the engine has run. The answers shape the work, which is why our engineers ask before pricing.
- Our engineers drain your tank of all the contaminated fuel.
- Lines cleaned, filter cleared. Whatever is left later is not the thing that created the trouble.
- Our technicians put new diesel in and bleed the system.
- The motor is started and checked to make sure it runs correctly on new diesel.
After that it's ready to pull away. Permanent damage is very uncommon when it has been caught soon, and since everything is done where your car is, it never has to be taken to a workshop.
AdBlue in a diesel tank in Hawley is a distinct problem
The problem is not the same, though the opening rule is — don't fire it up — if what went in was AdBlue rather than petrol. Petrol does two things to diesel: dilutes it, and takes away the lubrication the fuel system depends on. AdBlue is urea dissolved in water, and in a diesel tank it leads to corrosion and residue instead.
AdBlue removal around Hawley has a page of its own with the details on it, including why it's frequently the more serious of the two. Our engineers handle both.
What a petrol-in-diesel fuel drain will cost in Hawley
What changes the price is set out below, because this job isn't one job and our technicians can't frankly put a single number on this page.
- Whether your engine has been started or driven. This is the key one.
- The tank's capacity, set against how much of the wrong fuel got into it.
- Whether it's petrol or AdBlue.
- Whether a technician can safely get to your car and work on it, which rests on where your car is.
Tell us your car, the quantity and if it has run, and you'll get a clear answer instead of a range. For the car at home that's going nowhere and is not pressing, is fine too.
Hawley motorists ask us these about petrol in diesel
At a petrol station in Hawley, can you do a fuel drain there?
Yes — forecourts are where a good share of this takes place. We visit BP and the other forecourts nearby routinely, with the station's consent — tell us which one you are at when you call and we'll tell you whether our engineers can work there.
Is there a sensible amount of petrol in a diesel?
It rests on the ratio instead of the litres, and much more on whether the engine has run. What determines how much work is needed is whether that blend has been drawn through the fuel system — because although five litres in a nearly empty tank is a different matter from five in a full one, either way that is the question.
Petrol in my diesel, and I have driven the car
Switch off somewhere safe, then keep it that way after you stop. Driving moves the issue along — out of your tank, into your pump and injectors. Motorists fear it a good deal more than the recovery rate warrants, mind. The one really helpful thing left to you isn't restarting the vehicle.
Is a fuel drain going to void my warranty?
No. Carried out correctly, clearing and rinsing is no change at all, and the warranty from your manufacturer is untouched by it. Another reason to leave it switched off: running a diesel on petrol is the thing more likely to cause an argument with one.
Two-stroke oil in your tank, and then home?
No. It belongs to a separate fault from a different era, and petrol has thinned something no oil of that kind puts back. Petrol remains in that tank later on, whatever else goes in, and the pump gets no break from it.
A main dealer for petrol in a diesel — necessary?
There's no need to take it to a dealership, since our technicians drain and flush your car wherever it is.
Still with the vehicle?
Shut off is how it remains.
Turn it off somewhere safe and leave it off, if you have already driven it. Cold, parked, going nowhere: that's the best position to be in. Drivers fear this far more than they need to.
