Don't Start It Petrol in Diesel drains and flushes misfuelled cars where they are, on the forecourt, at the roadside or on a private drive, all over Addington and the rest of Kent. The very first thing to do is not to turn on the engine. While the motor has not run and the fuel is still inside your tank, a drain is nearly always all it requires, and the coming few minutes determine that, not how much went in. One ring our way will be sufficient: our technicians can explain what happens from here. Try this straight away. ## The next five steps: petrol in a diesel - Give a petrol motor diesel and it will generally fail to run at all, and so the driver stops there and so does the damage. Give a diesel petrol and the engine starts, it ticks over, it drives off — fine enough for several miles. People have that muddled, which is the thing they get wrong about petrol in a diesel in particular. So don't start the car. And having started, never believe it: your fuel system is grinding while you drive. - Diesel burns, and before it ignites it protects — your high-pressure pump, those injectors. Petrol does only the burning. So leave your ignition off too: flicking it on is commonly all it takes to prime that system, and priming moves petrol from the tank into exactly those components. - That advice presumes a diesel fuel system accepts petrol by percentage. It does not. Tip diesel on top and nothing at all is taken out; what you have is a fuller tank of the same mixture. And no, the type makes no difference — super unleaded is just petrol. - Stay put if it's sensible to. Hazards on, motor off, keep the car. Wherever you have stopped — the verge on Plowenders Close, anywhere — a difficult spot for us beats a started motor, and nothing is easier for us to handle than a vehicle that never shifted. - Find out where you are before phoning. A postcode starting ME19 5, and the name of whatever is nearest to you. Otherwise our van circles instead of turning up. - Phone 0333 366 0103. Prepare for three things — what got in, roughly how many litres, plus if the car has been turned over. Those answers decide whatever happens next. Don't drive it home. Petrol-thinned diesel has run through your high-pressure pump in real quantity on the trip in, and the way back would roughly double that for nothing at all. Phone us — the platform is good. There is no need to stand over that Volkswagen Golf at West Malling whilst the work happens, and we would much rather speak to you tonight than discover on Monday. ## Can petrol be pumped out of your diesel at a forecourt? Plenty of this work begins at a pump, so a large chunk of that ends up finished at one. We work on petrol station forecourts routinely, with the owner's agreement, so if you are still at BP that is generally where this drain takes place. A filling station is the only setting the mistake gets halted before your motor has run. The few seconds between reading the receipt and going for your key settle how much requires cleaning. Anywhere other than the forecourt — a car park, a private drive, a lay-by — the car was fired up and moved to get there, so fuel was pulled from the tank, through the filter then into the high-pressure fuel pump. That means your lines and your filter require cleaning as well as your tank. It is not a disaster, and our engineers can still sort it out where the car is. Staff will generally pitch in pushing it clear of the petrol pump, which lets the next customer get past. Accept the assistance. Four vehicle lengths isn't worth the risk. We will come out to you, clear your tank, rinse those fuel lines then put new diesel in so you can drive away. So if petrol went into your diesel Renault Clio around Addington and you're stuck outside Tesco with a boot loaded with shopping, phone us — and don't crank it once more to exit the space. A mile or so at easy throttle draws little fuel, so these are usually the simple ones. ## Parts our team cover around Addington Ryarsh, Offham, New Town, Tower Hill, Wrotham Heath — each of those on our journeys that bring us over to Addington itself, a rural village. There are dedicated pages for the majority of locations in Kent, and the ones named above are merely the nearest neighbours — so yours being left off that list tells you nothing about if our technicians come. Contact us and ask rather than assuming — county lines particularly, and anywhere your satnav may misread. Check this map for the area included on this page. Your car does not need to move to us. We work across every bit of that — roadside, forecourts, driveways, car parks. Your diesel Peugeot 308 will have felt completely usual on the way back from Offham Primary School. They all do, and that's the catch with petrol in a diesel instead of the other way round. Put diesel in a petrol car and it generally will not run, and so the driver stops and the harm stops with them. Put petrol in a diesel and it fires up, ticks over and drives off as though nothing has happened — all while your high-pressure pump works without the lubrication your fuel is meant to be giving. Nothing alerts you, because from the driver's seat there's nothing to alert you about. Phone us with roughly how far you drove and how hard you drove it; the second answer counts more than the first. ## Kerbside call-outs around Addington The opportunity to pull over somewhere safe does not come to everybody. Hazards on at a lay-by somewhere, or pulled onto the verge beside East Street since you noticed after setting off — we take that call so often that it is the ordinary kind. Whether you wait with the motor or step clear of it rests on whether sitting nearby seems sensible. Every mile a diesel obliges you for on petrol draws the mix further into the system — and oblige it frequently will, which is why your engine does not get restarted to limp somewhere handier. Driving on does your car far more harm than a technician driving out to a difficult location, and that's no bother for us. ## Petrol in a diesel, and your car has gone The local M20 is the road that matters here, and it runs under a mile from Addington. Some way along, and onto it in the first place: a misfuelled diesel will often do both before anything seems wrong. What you get then is rarely a clean stop. Power falls away, the idle goes uneven, and there may be some smoke. Get off at the first safe exit, switch off, and do not restart the car to move it. Suppose the worst of that on a long trip. Anything close to the under 25 miles to the nearest city, and the mixture has been through your filter, through your pump, through the injectors. Say so when you call. What we bring differs. Nothing is getting worse while it waits. Whatever the diesel Ford Focus did on the way to West Malling Golf Course, it is doing none of that now: the pump isn't turning. So take your time — but don't drive it home to buy yourself any. ## A little about Addington Addington is a small village in Kent, situated inland at an elevation of 48 metres, and is located near the villages of Ryarsh, Offham, and New Town. Addington has a population of approximately 547 residents and comprises predominantly detached housing. Addington is within commuting distance of London, being around 25.9 miles from the city, and is also close to the nearest city of Southend-on-Sea, which is 21.7 miles away. ## What follows when we arrive with you around Addington - Our technicians find out what was put in, how much, and whether your engine has run. The responses shape the work, which is why we ask before giving a price. - Our engineers drain that tank of all the tainted mixture. - What is left in your system should not be what started the trouble, so the fuel lines get flushed and the filter cleared. - The fuel system gets primed, on clean diesel. - Our engineers start the car and make sure it runs smoothly on new diesel. After that it's ready to set off. Long-term damage is very unusual when it has been noticed soon, and since everything is done where the car is, it never needs to be taken to a workshop. Pulled off the forecourt, read the receipt, and parked the diesel Mercedes E-Class up close to St Margaret a few hundred yards later? That's about as well as this goes once your engine has turned. Phone us then leave it off. The short distance truly assists, but it was still a start and a drive, and so thinned fuel has arrived at the filter and your pump — which is why our engineers rinse the fuel lines instead of only emptying the tank. ## AdBlue in a diesel tank in Addington is a different job Do not crank it: that opening instruction stands whether what was put in was AdBlue or petrol. What differs is the fault itself. The protection a fuel system depends on is taken away by petrol, which thins your diesel. AdBlue is urea in water, and in a diesel tank it causes rust and deposits instead. AdBlue removal around Addington has a page of its own with the full story on it, including why it is frequently the more serious of the two. Our engineers cover both. ## How much is a petrol-in-diesel fuel drain in Addington? What moves the figure is laid out below, as the job isn't one job and we cannot honestly put a single figure on this page. - This is the big one: whether your engine has been started, or driven. - How much of the wrong fuel went in, judged against how much that tank takes. - The kind of fluid in the tank, petrol or AdBlue. - Access: the vehicle's position, and if working on it there's safe for a technician. The car, the quantity, whether it has run — give us those and the answer comes back firm rather than as a range. Motor at home, going nowhere, nothing urgent about it — is fine for that. ## Petrol in diesel queries from Addington drivers ## At a petrol station in Addington, can you do a fuel drain there? Yes, and it's where a fair part of this work happens. Routinely, provided the site consents: JET, plus every other forecourt nearby. Say on the phone where precisely you have stopped. Whether our technicians can work in that spot is something our technicians answer straight away. ## How much petrol is too much for a diesel? Whether your motor has run matters much more, though the ratio matters too, rather than the litres. Five litres in a nearly empty tank is a separate case from five in a full one — but either way, the thing that determines how much work is needed is if that mixture has been sucked through the fuel system. ## Petrol in my diesel, and I have driven it Switch off somewhere sensible, and keep it that way after you stop. Not restarting it is the single most useful thing available to you now. Driving does shift the trouble out of that tank and into the pump and injectors, yes, and it stays fixable a lot more regularly than motorists assume. ## Will a fuel drain void my warranty? It isn't a change, so a drain then flush carried out correctly doesn't cancel a manufacturer's warranty. A disagreement over a warranty is likelier to come from running a diesel on petrol — so leave it turned off. ## Two-stroke oil in that tank, and then home? What petrol has weakened is not put back by two-stroke oil, which is an old remedy for a separate problem. So no. Petrol stays in that tank after that, whatever else goes in, and the pump gets no reprieve from it. ## A main dealer for petrol in a diesel — needed? Wherever your car is, our engineers drain and flush it there, so a visit to the main dealer does not come into it. ## You, and your car, still together? Keep the car switched off. Driven it already? Then somewhere safe, stop, switch off, and no restarting the car afterwards. This is recoverable from far more frequently than drivers expect, and a parked, cold vehicle is the best position to be in. On-site fuel draining in Addington and throughout Kent — at the kerbside, on the forecourt or at home.
