If you have not fired up your engine as yet, do not. A drain and nothing else is nearly always what a motor needs while the petrol is still inside your tank and your engine has not run, which is why it's the following few minutes that matter, not how much got in. Petrol in Diesel travels to the car wherever it has come to rest in Rowde or the rest of Wiltshire, on the forecourt, at the roadside or on a drive, and drains and cleans it there. Ring us before everything else begins, and you'll see what comes next. ## The first five steps: petrol in a diesel - Never start it. Fired up regardless? Then never depend on it. Diesel in a petrol vehicle typically won't run, so the driver stops and the damage halts with them. Petrol in a diesel? It starts. It ticks over. It drives off normally, for several miles. Motorists get that backwards. It's not all right — that fuel system is wearing every mile you cover. - Diesel ignites, and before it ignites it protects — that injection pump, its injectors. Petrol handles only the burning. So leave the ignition be as well: turning it on is often all it takes to prime that system, and priming draws petrol from your tank into just those components. - Topping up gets rid of nothing. It hands you a bigger tank of the same blend, because a diesel fuel system does not accept petrol by percentage as that guidance assumes — so don't tip diesel on top to water down it. Grade is irrelevant too: super unleaded is petrol. - Sit tight if it's sensible to. Hazards on, engine off, leave it. Wherever you have stopped — the verge on Marsh Lane, anywhere — a tricky place for us beats a started engine, and nothing is simpler for us to sort out than a vehicle that never shifted. - A van arriving instead of circling hinges on two things: a postcode starting SN10 2, and whatever is closest to you with a name on it. Get both prepared before you dial. - Three replies settle your whole call-out: the liquid you put in, the rough amount involved, and if anything has been going since. Our line is 0333 366 0103. How many miles you travelled is what our technicians query, not how long the motor has been parked — and here's why. Diesel performs two jobs on its way through an engine: it combusts, and before burning it protects that injection pump and the injectors. Petrol handles the first only. So a quick refuel on the trip in, the realisation coming close to eleven, and a diesel Renault Megane parked outside Melksham since quarter past eight means those few miles were travelled with your pump labouring on a liquid robbed of a lot of its protection. Phone then leave the vehicle right where it stands. ## Can petrol be drained from your diesel at the forecourt? A large chunk of this job is completed at a forecourt, because that is where it often begins. The drain typically gets done there and then. Still on the forecourt at Murco? Given the site's consent, that's a place our technicians work, and routinely. Nowhere except the forecourt can this be spotted with your motor still untouched. The few seconds between seeing your receipt and reaching for the keys settle how much needs cleaning. Anywhere other than the forecourt — a car park, a drive, a lay-by — the car was started and driven to get there, so fuel was sucked from the tank, through the fuel filter and into the high-pressure pump. That means the fuel lines and the filter require rinsing as well as that tank. It is not a disaster, and we can still put it right where the vehicle stands. Move the vehicle out of the way if the attendants offer, and they usually will. The next motorist gets by the pump, and that is worth doing. Four car lengths is not worth a start. Petrol in your Skoda Octavia, and it takes diesel? Shopping in your boot, you at M&S Simply Food, somewhere in Rowde? Then phone us, and leave the motor out of it — not even to leave the bay. A technician gets to you. Tank drained, fuel lines flushed, clean diesel in, and home you go. Easy throttle over a mile draws little, and so these are usually the easy ones. ## Service in Rowde The same trips take us to Tanis, Mid Wilts Way, Martinslade, Sells Green and Devizes along with Rowde, which is a rural village. Not on the list? That says nothing. The places above are simply the closest few, and nearly all places in Wiltshire have a page of their own somewhere on this site. Presuming is the thing to avoid, especially on the boundary or somewhere your satnav fails. Phone and check. That map is the area this page covers. All of it is territory we serve: a kerbside, a forecourt, a private drive, a car park. You don't bring the car anywhere. Each restart primes the fuel lines and drags more petrol past the filter then into your pump. So a misfilled diesel BMW 3 Series on the zig-zags outside Rowde CofE Academy is a nuisance, whereas the same vehicle started three more times to be courteous is a fuel system and not a tank. Someone will urge you to move the vehicle out of that gateway and deal with it later. Please don't. Stay put, let people complain, and call us. ## Rowde: broken down where you stopped Not everybody gets a chance to pull in anywhere suitable. If you noticed after setting off and ended up along the verge of High Street, or in a lay-by somewhere with your hazards flashing, that is a normal call for us rather than a rare one. Okay where you are? Remain with it. Not okay? Move out and away from it. It will usually oblige. A diesel running on petrol limps along quite willingly, and that's the problem: restart the vehicle to get to somewhere handier and the mix goes further into your fuel system with every mile covered. We'll bring the van to a difficult place without any fuss, and for the car that is much better than driving on. ## So you've run it? Petrol in a diesel over a few miles This is where the M4 matters, under 15 miles away from Rowde. Some way along, and onto it in the first place: a misfilled diesel will often manage both before anything seems wrong. What you get then is rarely a clean stop. Power ebbs away, your idle turns lumpy, and there may be some smoke. Get off at the next safe exit, turn off, and do not start it to move it. It affects what our engineers bring, and so say so when you call: on a longer trip — anything close to the under 15 miles to the nearest city — assume the contamination has been through the filter, the pump and your injectors. Nothing is getting worse whilst it stands. Whatever the diesel Vauxhall Astra did on the way to Big Wood, it's doing none of that now: the pump is not turning. So take your time — but do not drive the vehicle home to buy yourself any. ## Where's Rowde? Rowde is a small village in Wiltshire, situated inland at an elevation of 73 metres, with semi-detached housing being the predominant type of accommodation. Rowde lies near the Mid Wilts Way and is close to the nearby settlements of Tanis and Martinslade. Rowde is approximately 14 miles from the city of Bath and around 83 miles from London. Rowde has a population of around 864 residents. ## What our engineers do when our engineers reach you in Rowde - We find out what went in, how much, and whether your engine has run. The answers change the work, which is why our engineers ask before giving a price. - Out comes the contaminated fuel. - We rinse the fuel lines and clear the fuel filter, so what is remaining in the system isn't what started the trouble. - Bleeding your system follows, once new diesel is in. - Your engine is turned on and checked to be sure it runs correctly on fresh diesel. From there, you are ready to drive away. Our technicians do all of it wherever your car has come to a stop, which means it never has to be taken to a garage, and if it has been caught soon, it's very rare for there to be lasting damage. ## A separate problem: AdBlue in a diesel tank in Rowde The problem isn't the same, though the first rule is — do not crank it — if what went in was AdBlue instead of petrol. The protection a fuel system relies on gets taken away by petrol, which weakens the diesel. Corrosion and deposits are what a diesel tank ends up with instead, because AdBlue is urea dissolved in water. AdBlue removal around Rowde has a page of its own with the full story on it, including why it's often the more significant of the two. Our engineers handle both. Petrol in a diesel does its damage as a ratio, which is the reason our engineers ask at all: the same few litres sitting in an almost empty tank make a far stronger mix than they would in a full one. And petrol is rated on how well it resists igniting under pressure — the opposite of what a diesel wants — so a stronger mixture knocks more, smokes more, goes flatter. None of which means you need an answer ready. Nearly no one knows how full your tank was in a vehicle picked up two days ago, and our engineers work that out on the spot. Do call the hire or company firm first, though: some contracts want them to sign off the work, and that's far faster settled before than after. Then phone us about the Kia Sportage close to Caen Hill Flight of Locks. ## Budgeting for a petrol-in-diesel drain in Rowde One figure would not be honest here, as this is not one job. These are the things that move it: - Has it been run or driven? Nothing else counts for as much. - Wrong fuel in, against what the tank takes — that proportion. - AdBlue or petrol, whichever was put in. - Where your vehicle is, and if our van can safely get to and work on it. Tell us your vehicle, the quantity and if it has run, and you will get a clear answer rather than a range. Not urgent, with the car at home and going nowhere? Then is fine. ## Petrol in diesel queries from Rowde drivers ## Fuel drains on a Rowde petrol station forecourt Yes — forecourts are where a large share of this happens. Tell us which one you are at when you ring and we'll tell you if we can work there. With the owner's permission our technicians work at Esso and the other forecourts around town routinely. ## A couple of litres of petrol in a diesel — too much? Litres are not the yardstick. Proportion is, and a lot more than either, it matters whether anything has been run. What settles how much work is required is if that mix has been pulled through the fuel system — since although five litres in a nearly empty tank is a distinct case from five in a full one, either way that is the question. ## Petrol in my diesel, and I have driven the car Stop safely. Off. Nothing after that. Not restarting it is the single most valuable thing available to you now. Driving does shift the trouble out of the tank then into your pump and injectors, yes, and it remains fixable a lot more commonly than drivers assume. ## Will a fuel drain void my warranty? It's not a modification, so a drain and flush carried out correctly doesn't void a manufacturer's warranty. What's likelier to start a disagreement is a diesel that has been run on petrol. One more reason for your engine to remain off. ## Can I just add two-stroke oil and drive home? Two-stroke oil solves a separate problem, and an old one at that. Nothing it does puts back what petrol weakened. No. Your pump still has to live with it, since that tank still has petrol in it later. ## Main dealers and petrol in a diesel Not at all. Our technicians drain and flush the car wherever it is, so there is no need to bring it to a main dealer. ## Still with your car? Your engine remains off. Turn it off somewhere sensible then leave it off, if you have already driven it. This is recoverable from much more frequently than drivers assume, and a still, cold motor is the best position to be in. Mobile fuel draining in Rowde and across Wiltshire — at the kerbside, on the forecourt or at home.
