If you have not started your engine yet, don't. A drain and nothing else is almost always what a vehicle requires while the petrol is still in the tank and the engine has not yet been started, which is why it's the coming few minutes that matter, not how much went in. Petrol in Diesel comes to the car wherever it has stopped in Shirkoak or the remainder of Kent, on the forecourt, at the roadside or on a drive, and drains and cleans it there. Our technicians can explain what the next step is. Call us — this comes ahead of everything else. ## What next? Petrol in a diesel, step by step - Give a petrol motor diesel and it will usually refuse to run at all, and so the person stops there and so does the harm. Give a diesel petrol and the engine starts, it idles, it moves off — all right for a couple of miles. People have that reversed, which is the bit they get wrong about petrol in a diesel specifically. So don't start it. And if started, never trust it: the fuel system is wearing whenever you drive. - Flicking your ignition on frequently primes the system, and priming is what moves petrol out of that tank and into your pump and injectors. Those are the components diesel keeps greased on its way through, before it combusts. Petrol manages the burning and none of the protecting. Leave your ignition off. - Topping up gets rid of nothing. It gives you a bigger tank of the same mixture, because a diesel fuel system does not accept petrol by percentage in the way that advice suggests — so never put diesel on top to weaken it. Octane is beside the point too: super unleaded is petrol. - Wait where you are if you safely can. A car that hasn't moved is the easiest one to sort out, and we'd much rather come to an odd spot than have it started. If you are stopped on the verge on Redbrook Street, switch your hazards on then leave it there. - Before you call, get your location. Anything next to you with a name on it, plus a postcode that starts TN26 3 — that's what decides whether the technician shows up or circles. - Ring 0333 366 0103. Expect three questions — what was put in, roughly how much, plus if your car has been started. Your answers determine whatever happens next. Phone us before you collect the car. Petrol into a diesel Renault Megane this morning, and it outside Ham Street ever since? Then the wait has taken nothing from you: fuel in a tank is idle, and any wear happened on the journey in, when your pump was taking diesel that petrol had weakened. ## Draining petrol from your diesel at a forecourt Plenty of the work starts at a pump, which means a big portion of it gets finished at one. Still at Esso? Then that's normally where it happens. Station forecourts are normal for us, with the permission of the owner. No place except a garage can this be halted with your engine still unrun. Fuel pulled out of your tank and through your filter, right to the high-pressure fuel pump, is what occurs when the motor is started and the vehicle is moved to where it is now: the car park, the driveway or the lay-by, everywhere other than the forecourt. So the flush takes in the fuel filter and the fuel lines along with your tank. That's still not a catastrophe, and we put it right where your car sits. What decides it is whether the key was reached for in the seconds after your receipt was read. Out from the pump, the next driver can get by — so yes, let the staff help you move it. Worth it. Moving the car four bays does not warrant starting it. ## Do we serve your corner of Shirkoak? Shirkoak is a rural village, and so our vans go out to the town and to the villages around it on those same rounds: Woodchurch, Townland Green, Brattle, Brook Street and Brissenden Green. We do come. The places above are merely the closest neighbours, and a page exists for nearly all locations across Kent, so an absence from the list is not an absence from our coverage. Guessing is the mistake to skip, especially on the border or somewhere your satnav fails. Phone and check. The map is the ground this page covers. Kerbside, forecourt, drive, car park: the lot is ground we work on, and none of it requires the car to move to us. ## Broken down at the kerbside around Shirkoak A chance to pull in anywhere suitable does not come to everyone. Set off, then realised? Finished up along the verge of Bethersden Road, or parked in some lay-by with the hazard lights going? That is a routine call here. Not an odd one. Out of the car while it's not wise to wait in it, by it if it is. It will usually oblige. A diesel running on petrol limps along quite willingly, and that is the problem: start it up to reach somewhere better and the mix goes further into the system with every mile driven. Pressing on does the car far more harm than a technician coming out to an inconvenient spot, and that's no problem for us. ## Already driven it? Petrol in a diesel over a couple of miles Here is where the local M20 comes into it — under 10 miles from Shirkoak. A wrongly fuelled diesel will usually take you onto it and some distance along before anything seems wrong, while the symptoms when they arrive are generally a drop in power, an uneven idle and some smoke rather than a tidy stop. Take the next exit that is safe, pull up there, and never start it to reposition. Long trip? Anything close to the under 25 miles to the nearest city and you should suppose the lot — filter, pump, injectors, all of that got to by the mixture. Say that on the call, since it changes what goes in the van. Your pump isn't turning, and so whatever your diesel Nissan Qashqai did on the way to Hells Hole, none of it is going on now. Nothing is getting worse while it waits. Take your time over this — but never drive the vehicle home to buy any. ## A little about Shirkoak Shirkoak is a small village in Kent, situated inland at an elevation of 56 metres, and is located approximately 48.5 miles from London. Shirkoak sits near the villages of Woodchurch and Brattle, and is close to Townland Green. Shirkoak has a population of around 574 people and is characterised by predominantly detached housing. Shirkoak is also within commuting distance of the city of Canterbury, which is 18.6 miles away. ## Our visit around Shirkoak, step by step - The answers shape the work, which is why our technicians ask before pricing: what got in, how much of it, and if your motor has run. - Our technicians drain that tank of all the contaminated fuel. - Our technicians flush the lines and clear the fuel filter, so what is left in the fuel system isn't what caused the issue. - Our technicians put new diesel in and prime the fuel system. - It is run with fresh diesel in it, and we check that it is running smoothly. From there, you're ready to set off. Lasting damage is very uncommon when it has been caught early, and because all of it is done where your car is, it never has to be taken to a workshop. The pump rests ahead of your injectors, so whatever a worn-out one gives off moves on with your fuel — which is why we are blunt about not driving on. Ring us, then leave your diesel Audi A4 where it's close to Woodchurch Museum. ## AdBlue in a diesel tank around Shirkoak is a distinct problem AdBlue rather than petrol? Then the opening step is unchanged — the engine remains off — whereas this problem beneath it is a distinct one altogether. Weakened diesel, and no protection left for the system that depends on it. That's petrol. AdBlue is urea dissolved in water, and in a diesel tank it leads to rust and build-up instead. AdBlue removal in Shirkoak has a page of its own with the details on it, including why it's frequently the more serious of the two. Our technicians deal with both. A throttle gone soft, white smoke, an uneven idle, clattering: that's a wrongly fuelled diesel Ford Focus telling you what is wrong. Don't restart it to find a better location — turn off where you have stopped, near All Saints or anywhere else. ## Shirkoak costs for a petrol-in-diesel drain Our technicians cannot put one price on this page frankly, because the job isn't one job. What moves it: - This is the main one: whether the motor has been started, or driven. - Wrong fuel in, against what your tank takes — that proportion. - Whether it was unleaded or AdBlue. - Where is it? And can our van reach it and work there safely? A firm answer instead of a range is what you get for telling us three things: your vehicle, the quantity, and if it has run. If it is not urgent — the car is at home and going nowhere — works too. Drain it then put fresh diesel in — that is the tip you'll get, normally from somebody confident, and it's only half right. Do exactly that to a diesel Mercedes E-Class by Rare Breeds Centre and it would start, which is what makes the advice sound plausible. What occurs next is the trouble: the engine at once pulls the petrol left waiting 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. Our engineers flush the circuit and take the filter off where the car has a serviceable one, which is the difference between the vehicle being fixed and the car just starting. ## Petrol in diesel queries from Shirkoak motorists ## I am on a forecourt in Shirkoak. Can you drain it on the spot? Yes, and it's where a good share of this work takes place. We visit Tesco and the other forecourts around town regularly, with the station's agreement — tell us which one you are at when you ring and we will tell you if we can work there. ## 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. A nearly empty tank with five litres in it, against a full one with the same five: separate situations, definitely. Either way, the work required comes down to one thing, which is if your fuel system has had that blend sucked through it. ## I put petrol in my diesel and drove the car. Now what? Stop sensibly. Off. Nothing after that. Not restarting it is the single most useful thing available to you now. Driving does shift the trouble out of your tank then into the pump and injectors, yes, and it remains salvageable much more frequently than drivers assume. ## Is a fuel drain going to void my warranty? A manufacturer's warranty outlasts a drain then flush done to a good standard, which is no alteration at all. A disagreement over a warranty is likelier to come from running a diesel on petrol — so leave it turned off. ## Can I just add two-stroke oil and drive home? What petrol has weakened is not restored by two-stroke oil, which is an old workaround for a distinct fault. So no. Petrol remains in that tank afterwards, whatever else goes in, and your pump gets no respite from it. ## A main dealer for petrol in a diesel — essential? You don't need one. The vehicle is drained and cleaned wherever it is, with no need to take it to a dealership. ## Is the vehicle still with you? Turned off is how the car remains. Already driven it? Then stop somewhere sensible, switch off, then let the car remain that way. A still, cold motor is the best place to be in, and this is recoverable from much more frequently than people fear. On-site fuel draining around Shirkoak and throughout Kent — at the kerbside, on the forecourt or at home.
