Put Petrol in a Diesel Car in Bonnington? Don't Start It
Petrol in Diesel drains and cleans wrong-fuelled vehicles where they sit, on the forecourt, at the roadside or on a driveway, all over Bonnington and the rest of Kent. The very first thing to do is not to fire up the engine. When the motor has not run and the fuel is still inside the tank, a drain is nearly always all it requires, and the coming few minutes determine that, not how much was put in. Just one ring to us will be sufficient: our engineers can show you what follows after this. Try this straight away.
What to do next about petrol in a diesel
- Give a petrol motor diesel and it will normally fail to run at all, so the motorist stops there and so does the wear. Give a diesel petrol and the car starts, it ticks over, it pulls away — fine for several miles. People have that reversed, which is the bit they get wrong about petrol in a diesel specifically. So never start the vehicle. And once started, never believe it: your fuel system is grinding while you drive.
- Leave the car's ignition alone too. Diesel performs two tasks: it combusts, and before it combusts it protects your high-pressure fuel pump and the injectors. Petrol handles the first but not the second. Flicking the car's ignition on is frequently enough to prime your system, which carries this petrol out of your tank and into just those components.
- Do not tip diesel on top to thin it. A diesel fuel system does not tolerate petrol by percentage as that guidance presumes, and topping up takes out nothing — it only hands you a fuller tank of the same mixture. The octane makes no difference either: super unleaded is just petrol.
- A motor that hasn't shifted is the easiest one to deal with, and so remain where you are if you sensibly can. Parked on the verge on Bourne Road? Hazards on, then leave the car there. An odd spot works for us better than a started diesel.
- Get your position prepared before you phone. A postcode that starts TN25 7 and whatever is nearest to you with a label on it is the difference between a van arriving and the van circling.
- Dial 0333 366 0103. Expect three queries — what got in, approximately how much, plus if the engine has been started. Your replies settle everything that follows.
Draining petrol from a diesel at a forecourt
Much of this work begins at a forecourt, which means a big share of it is finished at one. Still at John Childs Garages? Then that's normally where it happens. Station forecourts are everyday for us, with the permission of the owner.
Nowhere else but a garage can it be stopped with the engine still untouched. We can still deal with it where it stands, even away from the forecourt. In a car park, on a drive or in a lay-by, the car has been fired up and driven there, and that sucked fuel through your filter then into the high-pressure fuel pump, all the way from that tank. None of that is a disaster, but the flush then has to go past your tank to the lines and your filter, and the few seconds between seeing the receipt and reaching for your key are what settle that.
Roll the vehicle out of the way if the staff offer, and they generally will. The next motorist gets past the petrol pump, and that is worth doing. Rolling it four spaces does not warrant starting the motor.
Do our technicians cover your end of Bonnington?
Aldington, Aldington Frith, Clap Hill, Bilsington, Chequertree — all of those on the rounds that take us over to Bonnington too, a rural village.
Not on this list? It means nothing. The names above are simply the closest few, and nearly all locations across Kent have a page of their own somewhere on this site. Guessing is the thing to skip, especially on a boundary or anywhere the satnav goes wrong. Phone and check.
The ground this page includes sits on the map. Your vehicle doesn't need to move to us. We operate throughout all of that — kerbside, forecourts, driveways, car parks.
Put diesel in a petrol motor and usually it won't run, and so the motorist stops there and the harm stops with them. Flip it — petrol into a diesel — and the thing fires up, ticks over and drives off as though nothing had happened, while the high-pressure fuel pump works without the protection the fuel is supposed to be supplying. That's the catch, and it is why the diesel Ford Focus will have seemed entirely ordinary coming back from Aldington Primary School. They always do. From behind the wheel there's nothing to alert you about, and so nothing alerts you. Ring us with approximately how far you travelled, and how hard; the second answer matters more than the first.
A diesel injection system works hydraulically as well as chemically: your fuel has to hold pressure, not just burn. Thin that fuel and pressure which should build then stay built leaks past gaps instead, leaving your engine a poorer, later, less even delivery than it was built about. Petrol weakens diesel, and diesel has to be heavy enough to seal the precision components it flows through — that is the whole process. It accounts for the ordinary Park Wood call too: a diesel BMW 5 Series that went out without fuss and came back down on power, uneven at idle, possibly smoking a little. None of which is the engine failing, and that's the bit worth hearing. The fuel has stopped acting like diesel. Put the fuel right and it stops.
About as well as this goes, once the engine has turned: away from the pumps, receipt read, and the diesel Citroen C3 parked close to Aldington Village Hall scarcely two streets on. Call us, then leave it off. A short hop does genuinely help. It was still a start and still a drive, though, and so the fuel filter and the pump have had weakened fuel through them — hence cleaning the lines rather than only emptying the tank.
Hire car or company car? Ring them before you call us — some contracts want the hire firm to sign off the work, and sorting that out first is a great deal faster than sorting it after that. Then call us about the Peugeot 2008 near Saint Rumwold's Church, and don't worry that you cannot say how full your tank was. Nearly nobody can, in a car they collected two days ago, and we work it out there. The reason we ask is that petrol in a diesel does its damage as a proportion: the same few litres in a nearly empty tank is a far stronger blend than in a full one. Petrol is rated on how well it resists igniting under pressure, which is the opposite of what a diesel needs — so the stronger that mixture, the more it knocks, smokes and goes flat.
Drain it and put fresh diesel in — that is the advice you will get, normally from a person confident, and it is only half right. Do precisely that to a diesel Vauxhall Corsa by St Peter & St Paul and it would start, which is what makes the suggestion sound sensible. What occurs next is the issue: the motor at once sucks the petrol left resting in your filter and the feed lines straight back through the pump, since emptying a tank does nothing about fuel that has already left it. Call us instead. We flush the circuit and take the filter off where the vehicle has a serviceable one, which is the difference between your car being fixed and the car only starting.
Roadside stops in Bonnington
Some people find no suitable spot to pull over whatsoever. If you worked it out after setting off and landed by the verge beside Rocky Bourne Road, or in a lay-by somewhere with your hazards going, that's a routine call for us instead of a rare one.
Out of the motor when it isn't sensible to sit inside, beside it if it is. Never start it up to get to a nicer location. It'll go — a diesel on petrol usually obliges — and each mile of obliging draws the mix deeper into the system. A van driving to a difficult spot is no trouble for us, and it is much better for your car than pressing on.
Already driven it? Petrol in a diesel after some miles
Your M20 is the road which matters here, and sits under 3 miles from Bonnington. A misfuelled diesel will usually take you onto it and some distance along before anything feels wrong, and the symptoms when they arrive are usually a loss of power, an uneven idle and smoke rather than a neat stop.
Come off at the next safe junction, switch off, and do not restart the vehicle to reposition. Long trip? Anything near the under 25 miles to the nearest city and you should assume the lot — filter, pump, injectors, all of that reached by the petrol. Say that on the call, as it affects what goes in the van.
Bonnington itself
Bonnington is a small village in Kent, situated inland at an elevation of 34 metres, approximately 15 miles from Canterbury and 54 miles from London. Bonnington is characterised by its predominantly detached housing stock, reflecting its rural setting. Bonnington lies near other small settlements, including Aldington and Aldington Frith, and is surrounded by the countryside of the South East region.
What follows when our engineers reach you in Bonnington
- Our technicians ask first, quote after. What got in? How much? Has your engine run? Those answers shape what the work actually is.
- Our technicians drain that tank of the tainted mixture.
- What is left in the fuel system shouldn't be what created the trouble, so your fuel lines get cleaned and the filter cleared.
- Priming follows, once fresh diesel is in.
- Once it is turned on, our engineers make sure it runs correctly on fresh diesel.
At that point it is ready to set off. Everything is done where the vehicle is, so it never has to go to a garage, and when it has been noticed early, lasting damage is very unusual.
AdBlue in a diesel tank in Bonnington is a distinct job
The problem isn't the same, though the first step is — never crank it — if what went in was AdBlue rather than petrol. Petrol weakens your diesel and takes away the lubrication the system depends on. AdBlue is urea in water, and in a diesel tank it leads to corrosion and residue in its place.
AdBlue removal in Bonnington has a page of its own with the details on it, including why it is usually the more significant of the two. Our engineers handle both.
What a petrol-in-diesel fuel drain will cost in Bonnington
One price would not be fair here, because this isn't one job. These are the things that move it:
- This is the key one: whether the motor has been run, or driven.
- How much of the wrong fuel went in, set against how much the tank takes.
- Whether it was petrol or AdBlue.
- Access: the vehicle's position, and whether working on it there's sensible for our van.
The car, the amount, whether it has run — give us those and the answer comes back straight and not as a range. Not pressing, with your car at home and going nowhere? Then is fine.
Petrol in diesel questions from Bonnington drivers
At a petrol station in Bonnington, can you do a fuel drain there?
Much of what we do gets done nowhere else. So yes. Permission from the site is the condition. Given that, a forecourt like Tesco is somewhere we are often enough, along with the rest of them locally — so name yours on the call and you'll hear whether working there is possible.
A couple of litres of petrol in a diesel — too much?
Proportion decides it rather than litres — and more than either, whether the engine has run. Five litres into an almost dry tank isn't five into a full one, no. But both land on the same question in the end: has that mix been sucked right through, or has it not?
Petrol in my diesel, and I have driven the vehicle
Stop sensibly. Off. Nothing after that. It's fixable far more regularly than people assume, even though driving is what moves the issue from the tank into the pump and injectors — and the single most helpful thing you can do now isn't restart it.
Is a fuel drain going to void my warranty?
No. Carried out properly, emptying and cleaning is no alteration at all, and the warranty from your manufacturer is untouched by it. What's likelier to start a dispute is a diesel that has been run on petrol. One more good reason for the engine to stay off.
Could I put some two-stroke in and just drive?
What petrol has weakened is not restored by two-stroke oil, which is an old fix for a different fault. So no. Petrol remains in that tank after that, whatever else goes in, and the pump gets no reprieve from it.
Main dealers and petrol in a diesel
No. We drain and clean the vehicle wherever it is, so there is no need to take it to a dealership.
Is your car still with you?
Do not switch your engine back on.
If you have already driven the vehicle, pull in somewhere safe, turn it off and keep it off. Cold and parked, a car is in the best place available — and motorists fear this a lot more than the recovery rate warrants.
