Don't Start It If you have not turned on the engine as yet, don't. A drain and nothing more is almost always what a vehicle requires while the fuel is still sitting in your tank and the engine has not yet turned over, which is why it is the following few minutes that matter, not how much went in. Petrol in Diesel goes to the vehicle wherever it has come to rest in Woodhill or the rest of Shropshire, on the forecourt, by the roadside or on a drive, and drains and flushes it there. Our technicians shall tell you what your next move will be. Ring us — this comes before everything else. ## Your next five steps: petrol in a diesel - While you drive, the pump and the injectors wear. That is why you do not fire it up, and why you never depend on it once it has started. The trick about petrol in a diesel specifically — the part people get wrong — is that it drives off happily for the first mile or two. Diesel in a petrol engine normally will not run at all, which stops the motorist and stops the wear with them. This one lets you drive on. - Diesel ignites, and before it ignites it greases — that high-pressure fuel pump, the injectors. Petrol handles only the burning. So leave the ignition off as well: switching it on is often sufficient to prime your system, and priming carries petrol from your tank into just those parts. - Don't add diesel on top to thin it. A diesel fuel system does not cope with petrol by percentage as that advice implies, and topping up takes out nothing — it just gives you a larger tank of the same mixture. The grade makes no difference either: super unleaded is just petrol. - Stay put if it's sensible to. Hazards on, engine off, keep it. Wherever you have stopped — the verge on Woodhill Road, anywhere — a difficult spot for us beats a started diesel, and nothing is easier for us to handle than a motor that never shifted. - Before you call, gather your position. Anything nearest to you with a sign on it, plus a postcode beginning WV16 6 — that's what determines whether our van turns up or circles. - What went in, about how many litres, and if the motor has started — these three details decide the entire visit. Dial 0333 366 0103 and tell us. Quarter past eight, a quick fill-up on the way in, and the penny drops around eleven — by then the diesel Skoda Octavia has been left outside Kidderminster for three hours. Phone us then leave the car just where it is. The journey in is the part that is key now, since diesel performs two roles on its way through a motor: it burns, and before it burns it greases the high-pressure pump and the injectors. Petrol manages the first and not the second. So those couple of miles were covered with your pump working on a fuel that had lost most of the protection it is designed around — which is why the thing we ask is how far you went, not how long the car has been sitting. ## At a forecourt: draining petrol from a diesel A large portion of this job is done at a forecourt, as that is where it often starts. If you are still at the forecourt at the nearest petrol station, that's typically where the drain takes place — we operate on petrol station forecourts regularly, with the station's permission. A filling station is the one setting this can be stopped before the engine has fired. Fuel sucked out of your tank and through the filter, all the way to your high-pressure pump, is what occurs when the engine is started and your car is driven 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 filter and the fuel lines as well as your tank. That's still not a catastrophe, and our technicians put it right where your car sits. What decides it is whether the key was turned in the seconds after the receipt was read. Staff will generally pitch in pushing it clear of the petrol pump, which lets the next driver get through. Welcome the offer. Four car lengths is not worth the risk. Straightforward, these ones, and the reason is the mileage: a mile at easy throttle draws hardly any of it. Petrol into a diesel Dacia Duster somewhere around Woodhill, a boot loaded with shopping, and you stranded outside ALDI — call us. Leaving that spot is not worth another start. That tank gets drained where it sits, the lines purged, new diesel in, and you head home. ## Can our technicians cover your part of Woodhill? Woodhill is a residential suburb, and so our technicians are out to the town and to anywhere by it on the usual runs: Highley, Netherton, Stanley, Sutton and Hampton. Not on this list? It says nothing. The names above are just the nearest few, and nearly all places across Shropshire have a page of their own somewhere on this site. Call us and check instead of guessing, especially when you're on a boundary or somewhere a satnav struggles with. The area this page includes sits on our map. Your car doesn't need to come to us. We work across every bit of that — kerbside, forecourts, driveways, car parks. A diesel pump delivers fuel on demand, and a frantic morning dash asks for plenty — so three miles in the Peugeot 3008 seems like nothing and isn't. Twenty to nine by Highley Community Primary School, already late, the receipt in your hand reading unleaded: hazards on, ignition off, phone. ## Stuck by the kerbside somewhere around Woodhill? A chance to stop anywhere sensible does not fall to everybody. If you realised after setting off and landed by the verge on Ash Street, or at a lay-by somewhere with your hazards flashing, that is a routine call for us and not a rare one. Safe right there? Wait beside it. Not okay? Get out and away from it. Never restart the engine to nurse the vehicle somewhere handier — a diesel running on petrol will usually oblige, and every mile it obliges for is dragging that mix further into the system. A van coming to a difficult location is no problem for us, and it is a lot better for your car than carrying on. It will start. It will pull away perfectly well. That is the problem, as a diesel on a weakened tank runs normally while wearing down the components its fuel should be protecting. So no, never try the trip home from Castle Inn — leave the Mercedes E-Class and ring us. ## Run it already? Pull over, and see below Here is where your M54 comes into it — under 15 miles from Woodhill. A misfilled diesel will often take you onto it and some distance along before anything feels wrong, while the symptoms when they appear are typically a loss of power, a rough idle and some smoke rather than a neat stop. Never restart it to move it. Pull off at the next safe junction and switch off. On a longer drive — anything near the under 15 miles to the nearest city — take it the mixture has been through the filter, the pump and your injectors, and say so when you ring. It alters what we bring. Here's the full process. Diesel needs enough body to seal the close tolerances it goes through, and petrol takes that away. That's it. Which explains the usual Severn Valley Country Park call — a diesel BMW 5 Series, out there without a murmur and back down on power, uneven at idle, perhaps a bit of smoke. Injection systems work hydraulically as well as chemically, so the fuel has to hold pressure and not just burn; thinned, it leaks past those clearances instead of building, and delivery comes poorer, later, less even than the engine was engineered around. Not a failing engine, though. Fuel that has stopped acting like diesel. Put that right and it stops. ## Where's Woodhill? Woodhill is a suburban area in Shropshire, situated inland at an elevation of 119 metres, with semi-detached housing being the predominant type of accommodation. Woodhill lies approximately 14 miles west of Wolverhampton and 117 miles northwest of London, near the villages of Highley and Netherton. Woodhill has a population of around 1978 residents, living in a relatively quiet area surrounded by countryside. Woodhill is also close to the village of Stanley, which provides local amenities. ## What follows when our technicians get to you around Woodhill - We establish what went in, how much, and if your engine has run. The answers change the work, which is why our technicians ask before giving a price. - The tainted mixture is pulled out of that tank. - Lines purged, filter cleared. Whatever is left after that isn't the thing that created the problem. - The fuel system gets bled, on new diesel. - Our engineers fire it up and check it runs properly on fresh diesel. Your car is then ready for you to pull away. Our engineers do all of this wherever your car has come to a stop, which means it never has to go to a workshop, and when it has been noticed quickly, it is very rare for there to be lasting damage. ## AdBlue in a diesel tank in Woodhill is a separate problem AdBlue instead of petrol? Then the first step is unchanged — the engine stays off — whereas the fault beneath it's a distinct one altogether. Petrol does two things to diesel: dilutes it, and takes away the lubrication your fuel system depends on. Urea dissolved in water, AdBlue, and in a diesel tank that leads to rust and deposits. Our engineers cover both, and AdBlue removal in Woodhill has its own page with the full story — including why it is frequently the more significant of the two. ## Woodhill pricing for a petrol-in-diesel fuel drain Our engineers can't put one number on this page truthfully, because this job is not one job. What moves it: - Started? Driven? Either answer counts more than anything else on this list. - How much of the wrong fuel was put in, judged against how much your tank can hold. - AdBlue or unleaded, whichever went in. - Whether a van can sensibly get to the car and work on it, which rests on where your car is. The car, the amount, whether it has run — give us those and the answer comes back firm rather than as a range. Not time-critical, with the vehicle at home and going nowhere? Then does this job. ## Questions our technicians hear about petrol in diesel in Woodhill ## At a petrol station around Woodhill, can you do a fuel drain there? Yes — forecourts are where a big share of this gets done. Tell us which one you're at when you phone and we will tell you if our technicians can work there. With the site's agreement we work at Shell and the other forecourts locally routinely. ## How much petrol in a diesel is too much? It rests on the ratio rather than the litres, and much more on whether the engine has run. A nearly empty tank with five litres in it, against a full one with the same five: separate scenarios, definitely. Either way, the work required comes down to one thing, which is if your fuel system has had that mix sucked through it. ## Petrol in my diesel, and I have driven it Somewhere safe, then stop, then switch off and leave it off. Driving is what moves the issue from that tank into your pump and injectors — but it is recoverable a lot more often than drivers assume, and the single most valuable thing you can do now is not restart the vehicle. ## Will a fuel drain void my warranty? A manufacturer's warranty survives a drain then flush done to a good standard, which is no modification 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? No. It belongs to a distinct problem from a different era, and petrol has thinned something no oil of that kind restores. Your tank still has petrol in it later, and your pump still has to put up with it. ## Does petrol in a diesel have to go to a main dealer? There's no need to bring it to a main dealer, since our engineers drain and flush your car wherever it is. ## Still with your vehicle? That engine remains off. Driven it already? Then somewhere sensible, stop, switch off, and no restarting the vehicle later on. Cold and parked, a motor is in the best place available — and people fear this much more than the recovery rate warrants.
