If you have not turned on your engine as yet, don't. A drain and nothing else is almost always what a car needs while the fuel is still sitting in your tank and the motor has not yet run, which is why it is the coming few minutes that matter, not how much got in. Petrol in Diesel travels to the car wherever it has ended up in Coton Green or the remainder of Staffordshire, on the forecourt, by the roadside or on a drive, and drains and flushes it there. Call us before everything else starts, and you will learn what follows after that. ## What now? Petrol in a diesel, step by step - Never fire it up. Started all the same? Then don't trust it. Diesel in a petrol vehicle typically cannot run, and so the person stops and the wear ends with them. Petrol in a diesel? It starts. It idles. It drives off normally, for a few miles. People get that confused. It is not okay — the fuel system is wearing down every mile you cover. - Diesel combusts, and before it ignites it greases — the high-pressure pump, the injectors. Petrol handles only the burning. So leave your ignition be also: turning it on is often sufficient to prime the system, and priming carries petrol from the tank into just those parts. - Topping up takes out nothing. It hands you a bigger tank of the same mixture, since a diesel fuel system does not accept petrol by percentage the way that advice suggests — so do not add diesel on top to thin it. Octane is immaterial too: super unleaded is petrol. - Sit tight if it is sensible to. Hazards on, ignition off, keep it. Wherever you have stopped — the verge on Coton Lane, anywhere — a difficult place for us is better than a started motor, and nothing is quicker for us to sort than a motor that never shifted. - Know where you are before phoning. A postcode beginning B79 8, and the name of whatever is closest to you. Otherwise the van circles rather than turning up. - Ring 0333 366 0103. Expect three things — what went in, roughly how much, and whether the motor has been turned over. The responses shape everything that follows. Petrol in a diesel Volkswagen Golf, sitting at Tamworth since breakfast? The wait has cost you nothing — fuel sitting in a tank is dormant. It was the trip in that pushed weakened diesel through your pump. Phone before you collect the car. ## Clearing petrol from your diesel at a forecourt It begins at a pump, mostly. Often enough the work finishes at one too. Still at BP? Then that's usually where it happens. Petrol station forecourts are routine for us, with the permission of the station. Nowhere else except a garage can it be halted with the motor still untouched. The few seconds between checking the till receipt and going for the key determine how much requires rinsing. Everywhere other than a forecourt — a car park, a private drive, a lay-by — the vehicle was started and moved to get there, so fuel was pulled from the tank, through the fuel filter then into the high-pressure pump. That means the fuel lines and your filter need cleaning as well as that tank. It is not a calamity, and we can still sort it out where your car sits. Out from the pump, the next customer can get through — so yes, let the staff help you wheel the vehicle. Well worth doing. Firing the car just to shift four car lengths is not. Car parks like the one at Co-op Food are a spot our technicians attend frequently, and the fuel is rarely the awkward part. That bay is: motors either side, a trolley shelter behind, sometimes a height barrier on the way in that decides if a technician can reach you at all. So tell us how hemmed in you are when you phone, and which way the car is facing. If we can't work alongside your diesel Renault Clio we'll shift the vehicle without starting it — and that's not pedantry about a couple of seconds of running. Any start primes the fuel system and draws more of that mixture out of that tank and towards your pump, so a vehicle shuffled twice into a better space has silently become a bigger job than one left exactly where it stopped. ## Will our engineers serve your end of Coton Green? As a residential suburb, Coton Green gets a steady visit, whilst the places round about come along on the same journey: Leyfields and Coton Farm, Coton and The Leys, Gillway. There are separate pages for nearly all locations around Staffordshire, and the ones listed above are merely the nearest neighbours — so yours being missing from this list says nothing at all about if our technicians come. Contact us to ask rather than presuming, particularly if you're on a boundary or anywhere a satnav struggles with. That map shows the patch the page spans. The vehicle does not need to move to us. We work throughout every bit of it — kerbside, forecourts, driveways, car parks. A passer-by will advise you to move it out of the gateway and deal with it later. Please don't. A wrongly fuelled diesel Skoda Octavia on the zig-zags outside Coton Green Primary School is a nuisance; the same vehicle fired up three more times to be helpful is a fuel system rather than a tank. Each restart primes the fuel lines and pulls more petrol past your filter then into your pump. Leave it there, let people grumble, then call us. ## Broken down at the kerbside in Coton Green The chance to pull over somewhere safe does not fall to everyone. Set off, then realised? Finished up by the verge of Cromwell Road, or parked in some lay-by with the hazards flashing? That is a normal call here. Not an unusual one. Fine right there? Sit with it. Not okay? Climb out and away from it. Every mile a diesel obliges you for on petrol draws the mix further into your fuel system — and oblige it frequently will, which is why your engine does not get restarted to limp somewhere better. We will bring our van to an awkward place without any fuss, and for the car that is a lot better than pressing on. ## Petrol in a diesel, but the motor has travelled This is where the M6 Toll counts, under 5 miles from Coton Green. Some distance along, and onto it in the first place: a misfilled diesel will usually do both before anything feels wrong. What you get then is rarely a tidy stop. Power drains away, your idle goes lumpy, and there may be smoke. The next sensible junction is the one to take. Switch off there, and leave the restarting alone. Long trip? Anything close to the under 10 miles to the closest city and you should suppose the lot — filter, pump, injectors, all of it arrived at by the mixture. Say that on the call, as it changes what goes in our van. Stop somewhere safe, switch off then ring us. Normal on the way out to Wigginton Park, gutless on the way back? Then look at that tank. Petrol weakens diesel; weaker fuel slips past the tightly fitted parts that build injection pressure; and the further the diesel Peugeot 308 went, the less of that pressure it held. ## A little about Coton Green Coton Green is a suburban area in Staffordshire, situated approximately 5 miles from the city of Lichfield. Coton Green sits in a relatively low-lying area at an elevation of around 68 metres, with nearby places including Leyfields and Coton Farm. Coton Green has a population of around 3277 people, predominantly living in detached housing. Coton Green is located inland, about 103 miles northwest of London. ## What comes next when our technicians get to you around Coton Green - Our engineers ask first, price after. What got in? How much? Has the motor run? Those responses change what the work actually is. - Our engineers drain the tank of all the contaminated fuel. - We purge the lines and clear the filter, and so what's remaining in the system is not what started the problem. - The fuel system gets bled, on clean diesel. - Once it is turned on, our engineers make sure it runs properly on clean diesel. Your car is then ready for you to drive away. Permanent damage is very rare when it has been caught quickly, and because everything is done where your car is, it never needs to be taken to a garage. Pulled off the forecourt, read your receipt, and left the diesel Nissan Qashqai up close to The Fitness Hub a few hundred yards later? That is about as well as this goes once the motor has turned. Ring us then leave the vehicle off. The short hop really assists, but it was still a start and a drive, so thinned fuel has got to the fuel filter and your pump — which is why our technicians rinse your lines instead of only emptying that tank. ## AdBlue in a diesel tank in Coton Green is a different problem AdBlue rather than petrol? Then the opening step is unchanged — the motor stays off — whereas the issue under it's a distinct one altogether. Petrol thins the diesel and removes the lubrication your fuel system depends on. AdBlue? Urea dissolved in water. Pour that in with the diesel and you get rust instead, plus deposits. Our engineers handle both, and AdBlue removal around Coton Green has its own page with the details — including why it's frequently the more serious of the two. ## What a petrol-in-diesel fuel drain will cost in Coton Green One price wouldn't be fair here, as this isn't one job. These are the things that shift it: - Whether the engine has been started or driven. This is the main one. - How much of the wrong fuel was put in, against how much your tank takes. - The sort of liquid in the tank, unleaded or AdBlue. - Access: the vehicle's position, and whether working on it there's safe for a technician. Tell us your vehicle, the quantity and whether it has run, and you'll get a straight answer instead of a range. Vehicle at home, going nowhere, nothing time-critical about it — is good for that. ## Petrol in diesel: frequent questions around Coton Green ## At a petrol station in Coton Green, can you do a fuel drain there? Yes — forecourts are where a large part of this gets done. Permission from the site is the condition. Given that, a forecourt like Sainsbury's is somewhere we are regularly, along with the rest of them locally — so name yours on the phone and you will hear if working there is possible. ## How much petrol is too much for a diesel? It depends on the proportion instead of the litres, and a lot more on whether your motor has run. Five litres in a nearly empty tank is a different case from five in a full one — but either way, the thing that settles how much work is required is if that mix has been drawn through the fuel system. ## I put petrol in my diesel and drove the car. What now? Pull over somewhere safe, turn off, and keep the car off. Driving is what takes the issue from that tank into your pump and injectors — but it is salvageable far more regularly than motorists assume, and the single most valuable thing you can do now is not restart the vehicle. ## Fuel drains and manufacturer warranties It's not a change, and so a drain then flush carried out properly 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 good reason for the engine to stay off. ## Can I just add two-stroke oil and drive home? What petrol has weakened isn't put back by two-stroke oil, which is an old fix for a different fault. So no. Later on? Still petrol in that tank, and a pump that has to cope with the stuff. ## Do I need a main dealer for petrol in a diesel? Wherever the vehicle is, our engineers drain and clean it there, so a trip to the main dealer does not come into it. ## Is your car still with you? Switched off is how it remains. If you have already driven it, pull in somewhere safe, switch it off then keep it off. A stationary, cold car is the best place to be in, and this is recoverable from much more frequently than motorists fear. Emptying misfilled motors, Coton Green and the rest of Staffordshire, wherever they are. Roadside. Forecourt. Home.
