Don't Start It Don't start the engine. While the petrol is still inside the tank and the engine has not yet been started, a fuel drain is almost always all it requires — and that is decided in the following few minutes, not by how much got in. Petrol in Diesel drains and cleans wrong-fuelled vehicles where they stand, all over Areley Kings and the rest of Worcestershire, on the forecourt, at the roadside or on a private drive. A single ring to us is sufficient: our engineers can show you what comes next. Make this first. ## Now what? Petrol in a diesel, in turn - Don't start the vehicle — and never rely on it if it fires up. This is the part drivers have wrong about petrol in a diesel especially. A petrol motor fed diesel generally just won't run, so the person stops and the wear stops with them. A diesel fed petrol generally starts, idles and pulls away quite happily for several miles. It isn't all right. It is grinding the fuel system whenever you drive. - Leave the car's ignition be too. Diesel has two tasks: it ignites, and before it combusts it protects your injection pump and those injectors. Petrol handles the first and not the second. Turning your ignition on is often all it takes to prime your system, which pulls the petrol out of that tank and into exactly those parts. - Never weaken it. Diesel put on top removes nothing, so all you get is more of what was already there, because percentage is not how a diesel fuel system tolerates petrol. Super unleaded? Just petrol. The octane makes no difference. - A car that hasn't moved is the quickest one to sort, so remain where you are if you safely can. Pulled up on the verge on Severn Manor Gardens? Hazards on, then leave the vehicle there. A difficult spot suits us better than a started diesel. - A van showing up instead of circling hinges on two things: a postcode starting DY13 0, and whatever is next to you with a label on it. Have both prepared before you dial. - Call 0333 366 0103. Say what got in, approximately how many litres, and if your car has fired. These three replies shape your whole visit. Quarter past eight, a rushed fill on the way in, and the penny drops close to eleven — by that point the diesel Volkswagen Golf has been left outside Hartlebury for three hours. Call us and leave the vehicle right where it sits. The run in is the part that matters now, as diesel performs two jobs on its way through the engine: it ignites, and before it burns it greases its high-pressure pump and those injectors. Petrol handles the first and not the second. So those couple of miles were covered with your pump labouring on a fuel that had shed much of the protection it is designed around — which is why the question our engineers ask is how far you drove, not how long the vehicle has been parked. ## Pump-side drains for petrol in a diesel Pumps are where this job mostly starts, and where a large portion of that closes. If you are still at the forecourt at Tesco, that is typically where this drain happens — our technicians work on petrol station forecourts all the time, with the station's permission. A filling station is the one location the mistake can be caught before the engine has started. The few seconds between checking the receipt and going for the key determine how much needs rinsing. Anywhere other than a forecourt — a car park, a private drive, a lay-by — your car was fired up and driven to get there, so fuel was drawn from the tank, through the filter then into the high-pressure pump. That means the fuel lines and your filter require flushing as well as that tank. It is not a calamity, and our engineers can still deal with it where the car sits. The staff will usually happily push the car away from the petrol pump so the next motorist can get through. That is worth doing. Shifting it four bays does not justify cranking the engine. We are in car parks like the one at Tesco all the time, and it is rarely the fuel that complicates them. It is the bay. Motors both sides. Trolleys stacked up behind. At times a height barrier at the entrance, which decides if our van gets to you at all. So mention how boxed in you are when you ring, and which way the car is facing. If there is no space to work next to that Renault Clio, we shift it without the motor. That isn't pedantry over a couple of seconds: starts prime things, blend comes out of the tank toward your pump, and a car shuffled twice for a nicer spot is gradually a worse job than one nobody touched. ## Areas we cover around Areley Kings The Walshes, Astley Cross, Stourport-on-Severn, Lower Heath, Dunley — all of those on our journeys that carry us across to Areley Kings as well, a residential suburb. Our technicians still come. Those places above are merely the nearest neighbours, and a page exists for nearly all locations around Worcestershire, so an absence from the list isn't an absence from our coverage. On a border, or somewhere a satnav can't find? Contact us to ask instead of assuming. This map shows the area this page covers. Every bit of that is territory we cover: a roadside, a forecourt, a private drive, a car park. You never move the vehicle anywhere. ## Roadside call-outs in Areley Kings Not everybody gets the opportunity to stop somewhere suitable. A normal call for us and not a rare one: worked out after setting off, landed on the verge on Windmill View or at a lay-by with the hazard lights flashing. Whether you stay with the motor or move clear of it turns on if being in it feels safe. Every mile a diesel obliges you for on petrol draws that mix further into your fuel system — and oblige it frequently will, which is why the motor doesn't get restarted to limp somewhere better. We will take our van to a difficult location without any trouble, and for the vehicle that is much better than driving on. A diesel Nissan Qashqai sitting in the car park outside The Old Beams with a tank full of petrol in it is a simple job, right up till someone drives it home. Leave the vehicle overnight and phone next morning. Nothing worsens while it sits. What we'll ask about is whether that drive there was brief and chilly, as that's where petrol is slowest to burn correctly — and whatever doesn't burn can slip past the piston rings and into the sump. ## So you've driven it? Petrol in a diesel after a few miles This is where your M5 matters, under 10 miles away from Areley Kings. A wrongly fuelled diesel will frequently get you onto it and some way along before anything feels wrong, and the symptoms when they arrive are generally lost power, a rough idle and smoke rather than a clean stop. The first sensible exit is the one to take. Turn off there, then leave the restarting alone. Long drive? Anything close to the under 15 miles to the closest city and you should presume the lot — filter, pump, injectors, all of it arrived at by the mixture. Say that on the call, since it changes what goes in our van. Don't drive it home to buy yourself time. You already have it: nothing gets worse whilst your car sits, as a diesel Peugeot 3008 parked outside Half-Crown Wood is doing none of what it did on the way there. The pump has stopped turning. ## About Areley Kings Areley Kings is a suburban area in Worcestershire, situated on the banks of the River Severn at an elevation of 51 metres. Areley Kings lies approximately 10 miles south of Worcester and 108 miles northwest of London, with nearby places including The Walshes, Astley Cross, and Stourport-on-Severn. Areley Kings has a population of around 4692 people, predominantly living in semi-detached housing. ## Once we arrive with you in Areley Kings: what happens - Three things get established before any quote — the fuel that got in, the amount, and whether anything has been run since. Each answer shapes the work. - Away flows the tainted fuel. - Our engineers purge the lines and clear your filter, so what is remaining in your system isn't what started the problem. - Clean diesel goes in, and then your system gets primed. - It is run with fresh diesel in it, and our engineers check that it is running smoothly. From there, you're ready to pull away. There's no need for a workshop at any point, as the work is all done where the car is, and when it is noticed early, lasting damage is very uncommon. Three things help when you ring from close to Areley Kings Village Hall: which side the filler is on, whether a technician can stand beside without blocking the road, and if the engine has run since you filled up. On-street is the most common spot our engineers work, and so the spot itself is rarely the problem — we would much rather deal with a tight parking spot than with a car that has been driven to somewhere more handy. We will drain the Mercedes E-Class, change the filter where there is a workable one, flush the lines then put fresh fuel through the entire circuit, because by this point the worst of it is resting in the lines rather than in your tank. ## A distinct matter: AdBlue in a diesel tank around Areley Kings AdBlue rather than petrol? Then the first instruction is unchanged — your motor stays off — while the fault beneath it is a different one altogether. Petrol does two things to diesel: weakens it, and removes the lubrication the fuel system relies on. AdBlue is urea dissolved in water, and in a diesel tank it causes rust and build-up in its place. Both are ours. There's a separate Areley Kings page for AdBlue removal, with the detail on it — including the reasons it frequently turns out to be the worse of the two. ## How much is a petrol-in-diesel drain in Areley Kings? Our technicians cannot put one number on this page honestly, since this job is not one job. What changes it: - Has it been run or driven? Nothing else matters for as much. - Wrong fuel in, against what that tank takes — that proportion. - Which was put in: petrol or AdBlue. - Whether our van can sensibly reach your vehicle and work on it, which hinges on where the vehicle is. Tell us your vehicle, the amount and whether it has run, and you'll get a firm answer rather than a range. If it isn't pressing — the car is at home and going nowhere — is fine too. ## Petrol in diesel questions from Areley Kings drivers ## I'm on a forecourt around Areley Kings. Can you drain the vehicle here? Yes — forecourts are where a large portion of this happens. Often, provided the site consents: Esso, plus every other forecourt nearby. Say on the phone where exactly you have stopped. Whether our engineers can work in that spot is something we answer straight away. ## A couple of litres of petrol in a diesel — too much? Litres are not the measure. Proportion is, and far more than either, it matters if anything has been run. What settles how much work is needed is whether that blend has been sucked through your fuel system — because though five litres in a nearly empty tank is a different matter from five in a full one, either way that is the query. ## Already driven it with petrol in your diesel? What then? Pull over somewhere safe, turn off, then leave the vehicle off. Driving shifts the problem along — out of that tank, into the pump and injectors. Motorists fear it a good deal more than the recovery rate warrants, mind. The one really valuable thing left to you isn't restarting the vehicle. ## My warranty — does a fuel drain void it? A drain and flush carried out correctly is not an alteration and does not invalidate a manufacturer's warranty. Another reason to leave it switched off: running a diesel on petrol is the thing likelier to cause a disagreement with one. ## Adding two-stroke oil, then driving home What petrol has diluted isn't put back by two-stroke oil, which is an old remedy for a distinct fault. So no. Your pump still has to put up with it, because your tank still has petrol in it afterwards. ## Main dealers and petrol in a diesel There is no need to take it to a franchised dealer, as our technicians drain and clean the vehicle wherever it is. ## Standing next to it? Switched off is the way the car remains. Driven it already? Then somewhere safe, stop, turn off, and no restarting the car later on. A stationary, cold motor is the best place to be in, and this is recoverable from much more frequently than people expect. Throughout Worcestershire and around Areley Kings: call-out fuel draining, at home or on the forecourt or at the kerbside.
