Petrol in Diesel drains and cleans wrongly fuelled cars where they sit, on the forecourt, by the roadside or on a driveway, across Tunstall and the rest of Kent. The very first thing to do is not to fire up the motor. While your engine has not run and the petrol is still inside your tank, a fuel drain is almost always all it takes, and the coming few minutes decide that, not how much got in. Our technicians will explain what the following move is. Phone — this happens before anything else. ## What to try now about petrol in a diesel - While you drive, the pump and the fuel injectors wear. That's why you never crank it, and why you do not depend on it once it has started. The thing about petrol in a diesel especially — the bit people get wrong — is that it drives away fine for the first mile or two. Diesel in a petrol engine generally can't run at all, which stops the person and stops the wear with them. This one lets you carry on. - Two tasks, diesel: it burns, and on the way through it keeps your high-pressure fuel pump and injectors oiled. Petrol only manages the one. Which is why the car's ignition stays off too — switch it on and you frequently prime that system, and that is petrol exiting your tank for exactly those components. - Topping up clears nothing. It leaves you a bigger tank of the same mix, because a diesel fuel system doesn't handle petrol by percentage the way that guidance suggests — so don't put diesel on top to dilute it. Grade is beside the point too: super unleaded is petrol. - Our team would rather drive to an awkward spot than have it started — so if you sensibly can, stay put. Nothing is quicker to sort out than a motor that has not shifted. On the verge on Tunstall Road, that means hazards on and keep the car. - Before you ring, gather your location. Anything closest to you with a sign on it, plus a postcode beginning ME9 8 — that's what settles whether the technician arrives or circles. - Ring 0333 366 0103. Tell us what was put in, about how much, and also whether the car has run. These three details decide the entire visit. The drive back would roughly double it, for no purpose at all. One commute has already forced a real volume of petrol-thinned diesel through the high-pressure fuel pump of your Volkswagen Passat. So leave the car where it sits. Phone us from the platform if that is quicker — no one needs you hovering over the car outside Sittingbourne whilst our engineers get on, and tonight is better than finding out on Monday. ## Pump-side drains for petrol in a diesel It begins at a forecourt, usually. Quite often it finishes there too. If you are still on the forecourt at Shell, that is usually where this drain takes place — we operate on garage forecourts all the time, with the station's agreement. Nowhere but a forecourt can the mistake be spotted with the motor still unrun. Anywhere else — a car park, a drive, a lay-by — the vehicle was switched on and driven to get there, which means fuel was sucked from that tank, through your filter then into your high-pressure pump. That is not a calamity, and we can still sort it out where it stands. It does mean your lines and the filter need cleaning as well as that tank, and that is determined by the few seconds between reading your receipt and reaching for your key. Attendants will normally help out pushing it away from the pump, which lets the next customer get past. Take the help. Starting the car just to shift four vehicle lengths isn't. Easy, these ones, and the reason is the miles: a mile at gentle throttle pulls little diesel. Petrol into a diesel Skoda Octavia somewhere in Tunstall, a boot full of shopping, and you stranded at Co-op Food — ring us. Leaving that space is not worth another start. The tank gets emptied where it sits, your fuel lines flushed, fresh diesel in, and you drive home. ## Service around Tunstall Tunstall is a rural hamlet, and so our technicians are out to it and to anywhere around it on those same rounds: Harmans Corner, Hearts Delight, Borden, Highsted and Sittingbourne. Our engineers do come. The names above are just the closest neighbours, and a page exists for the majority of places across Kent, and so an absence from the list is not an absence from our coverage. Call us and check instead of assuming — county lines especially, and wherever a satnav can struggle with. The patch the page includes appears on this map. All of that is territory our engineers cover: a kerbside, a forecourt, a private drive, a car park. You never drive the vehicle anywhere. ## Tunstall: broken down wherever you stopped Not everybody has the opportunity to pull in anywhere sensible. Hazards flashing at a lay-by somewhere, or stopped on the verge of Park Drive because you noticed after setting off — our technicians take that call so often that it's the ordinary kind. Whether you wait beside the vehicle or keep away from it rests on if sitting nearby is safe. Every mile a diesel obliges you for on petrol pulls the blend further into the system — and oblige it frequently will, which is why the engine does not get restarted to limp somewhere handier. However awkward the location, it's no problem for us to come to it, and that is a lot better for the car than carrying on. You head off at the end, once we have fired it up and confirmed it runs smoothly on clean diesel, with the fuel system bled. Before that, in the car park outside Beauty Of Bath, the tainted fuel comes out of your tank, the fuel lines get rinsed and the fuel filter comes off where your Nissan Qashqai has a replaceable one. Everything begins with three questions when our engineers get to the car: what was put in, how much of it, and whether it has been fired up since. ## Driven it already? Pull in, and check this under 3 miles out of Tunstall, your M2 is what matters now. A misfuelled diesel will usually get you onto it and some distance along before anything seems wrong, while the signs when they arrive are typically a loss of power, an uneven idle and smoke rather than a neat stop. The first sensible junction is the one to take. Switch off there, then leave the restarting alone. Long run? Anything close to the under 15 miles to the closest city and you should assume the lot — filter, pump, injectors, all of that reached by the contamination. Say that on the phone, because it affects what goes in the van. ## Where is Tunstall? Tunstall is a small hamlet in Kent, situated inland at an elevation of 53 metres, and is located near the villages of Harmans Corner and Hearts Delight. Tunstall lies approximately 14.8 miles from Southend-on-Sea and 38.7 miles from London, making it a relatively rural community. Tunstall has a population of around 778 residents, who mostly live in semi-detached houses. Tunstall is also close to the village of Borden, and is part of the wider Kent countryside. ## What our technicians do when our technicians arrive with you in Tunstall - Three things get asked before any price — your fuel that went in, the quantity, and whether anything has been run since. Each answer alters the work. - That tank gets emptied completely. - Fuel lines are rinsed through and the fuel filter cleared, leaving nothing in your system that started any of this. - The system gets bled, on fresh diesel. - It is run with fresh diesel in it, and our engineers confirm that it is running properly. From there, you are ready to pull away. Our technicians do all of it wherever the car has stopped, which means it never has to go to a garage, and if it has been noticed soon, it's very rare for there to be lasting damage. ## AdBlue in a diesel tank in Tunstall is a separate matter The issue is not the same, though the opening instruction is — never fire it up — if what was put in was AdBlue instead of petrol. Weakened diesel, and no lubrication left for your fuel system that relies on it. That's petrol. AdBlue is urea dissolved in water, and in a diesel tank it leads to rust and residue in its place. Usually the more serious of the two, AdBlue — and the detail sits on its own Tunstall page. Both are ours to handle. The slimmer petrol nozzle fits a modern diesel filler neck with practically no resistance at all, which makes this mechanical not sloppy. Unfamiliar locations see most of that for that reason. So: topped up close to Tunstall Village Memorial Hall without thinking, in a diesel Audi A3 you have had for two days? Ring us where you are. Hire and courtesy cars tend to get driven further before anyone realises, and mileage decides how much petrol gets to the injectors. ## How much is a petrol-in-diesel drain in Tunstall? Truthfully, no single price fits on a page like this. The job changes. Here is what moves it: - Whether your engine has been started or driven. This is the main one. - How much of the wrong fuel got in, weighed against how much that tank takes. - The kind of liquid in the tank, unleaded or AdBlue. - Whether a van can sensibly get to your car and work on it, which hinges on where your car is. The car, the quantity, whether it has run — give us those and the answer comes back firm instead of as a range. Not time-critical, with the car at home and going nowhere? Then is fine. Drain it then put new diesel in — that's the advice you will get, typically from a person sure of themselves, and it's half true. Do precisely that to a diesel Vauxhall Astra near Sittingbourne Cemetery and it would start, which is what makes the tip sound reasonable. What occurs next is the trouble: your engine immediately pulls the petrol left resting in your filter and the feed lines straight back through your pump, because emptying a tank does nothing about fuel that has already left it. Ring us instead. We flush your system and take your filter off where the vehicle has a workable one, which is the difference between the car being fixed and your car merely starting. ## Petrol in diesel: common questions around Tunstall ## Can you do a fuel drain at a petrol station in Tunstall? Plenty of what our engineers do takes place nowhere else. So yes. Tell us which one you're at when you ring and we'll tell you whether our technicians can work there. With the owner's agreement we attend Esso and the other forecourts nearby all the time. ## A couple of litres of petrol in a diesel — too much? Proportion decides it instead of litres — and more than either, whether the engine has run. An almost empty tank with five litres in it, against a full one with the same five: distinct scenarios, definitely. Either way, the work required comes down to one thing, which is if the system has had that blend pulled through it. ## I drove the vehicle after putting petrol in my diesel. Now what? Pull in somewhere safe, turn off, then keep the car off. Not restarting it is the single most helpful thing available to you now. Driving does shift the trouble out of your tank and into the pump and injectors, yes, and it remains fixable far more often than people expect. ## Will a fuel drain void my warranty? A drain then flush carried out properly is not a change and does not cancel a manufacturer's warranty. What is likelier to start a disagreement is a diesel that has been run on petrol. One more reason for the engine to stay off. ## Could I put some two-stroke in and just drive? No. Two-stroke oil is an old workaround for a different issue and it doesn't replace what petrol has diluted. Petrol remains in that tank later on, whatever else goes in, and your pump gets no reprieve from it. ## Does petrol in a diesel have to go to a main dealer? No. Our technicians drain and flush your car wherever it is, so there is no need to take it to a main dealer. ## Is your car still with you? Do not turn the car back on. Switch it off somewhere safe then leave it off, if you have already driven it. This is recoverable from much more often than drivers assume, and a still, cold vehicle is the best place to be in. At the roadside, on the forecourt or at home — call-out fuel draining in Tunstall and across Kent.
